Introduction
Welcome to the Intel® Pro Wireless Display (Pro WiDi) Implementation Guide. This guide is written for
those looking to test and deploy Intel Pro WiDi in their environment.
The complete Intel Pro WiDi experience occurs when both the client and receiver devices are Intel Pro
WiDi certified. This guide is focused on that primary setup scenario. This guide will also address
interoperability with other Miracast capable devices that also benefit and can be integrated into an
Intel Pro WiDi experience.
1.1
Why Wireless Display for Enterprise
Intel Wireless Display for Enterprise, commonly referred to as Intel Pro WiDi, enables a business
professional to share full high definition content to a nearby display via a local wireless connection.
With the diversity of video out options across a variety of mobile computing platforms business
professionals are often challenged to perform this daily task. Some screen sharing applications
require network infrastructure connectivity or specialized applications enabled for wireless display,
further impacting a simple daily task.
Built upon industry standard Miracast and enhanced beyond consumer Intel WiDi, Intel Pro WiDi
includes additional business environment use case scenarios along with Enterprise IT requirements of
security and manageability.
Intel® Pro Wireless Display
Implementation Guide
Page 5 of 52
One example of the additional use case scenarios is that multiple users can be connected with an
ability to manage who presents. In the first example below, multiple users are connected with the
ability to easily transition from one to the next.
In the second example, multiple users are connected with the session controlled by the meeting
leader.
In both scenarios, meeting latencies are minimized by removing the cables and adapters associated to
connecting and projecting to a conference room display. These two examples highlight use case
differences where Intel Pro WiDi is built for enterprise, enabling beyond a consumer solution.
NOTE: See the Intel Pro WiDi User Guide for more information on the user experience and session
management.

Intel® Pro Wireless Display
Implementation Guide
In addition to a business professional’s desire to connect and project their screen, those responsible
for Enterprise Information Technology (IT) in the business environment want to ensure the solution is
secure and manageable. A solution built for a home environment often lacks the security and
management needed in an enterprise.
The security features include enhancements that are enabled by default and can be further
customized specific to an environment. Preventing bridging between an infrastructure and Wi-Fi
direct session is often a native feature of the host operating systems, with additional options on
Microsoft Windows 7 platforms. Connection confirmation for the user to ensure they are connected
to the correct display is defined on the client application. Session pairing, content protection,
whether a USB input device connected to the receiver can be used, and other settings specific to the
wireless display receiver can be defined by IT administrators.
An important capability to an enterprise with multiple locations using wireless display is the ability to
remotely manage the receivers. Select Intel Pro WiDi receiver vendors enable this functionality.

1.2
Purpose and Structure of this Document
The main sections of this document address specific roles related to Intel Pro WiDi deployment,
identifying key responsibilities and decision points. The target audience of this guide is dependent
upon the role or job description.

PC Lifecycle: This role focuses on those responsible for client computing environment.
Those responsible for the PC Lifecycle will be intimately familiar with the client computing
hardware inventory, imaging, update, and related events. Specific to Intel Pro WiDi,
knowledge of specific hardware, driver, and software is required to ensure a great experience.

Conference Room: Often a part of the facilities team, this role focuses on those responsible
for audio-visual setup and support for the conference room environment. They will be
intimately familiar with room build out such as ports and connections, conference room
displays, whether video scalers are present, and so forth. Specific to Intel Pro WiDi, the
placement and connections to the receiver along with initial configuration to ensure a great
experience apply to the conference room setup.

Network Infrastructure: This role focuses on wireless network infrastructure and
management of network devices. The individuals involved are intimately familiar with the
wireless channel spectrum utilization in the environment and how to fine tune the
environment to ensure a great connectivity experience. Specific to Intel Pro WiDi, this
individual will define the initial configuration settings, may be involved with remote
management of the wireless display receivers and helps ensure a great wireless display
experience.


1.3
Components Overview
Intel Pro WiDi consists of three primary components: one of more transmitting devices, a single
receiver device, and a single display. All three components should be located in the same room for a
successful experience.
Specifics on Transmitters are referenced in Section 2. The Receiver is certified and branded for Intel
Pro WiDi. For the purposes of this document, the Actiontec ScreenBeam Business Edition will be
used. The display is a monitor, projector, flat panel, or similar device that may be located in a
conference room or collaboration area. In some cases, the receiver and display may be the same
device. Although Intel Pro WiDi can be used in a single user workspace area, other solutions such as
Intel Wireless Docking may be more appropriate.
1.4
Architectural Overview
The foundation of the wireless display session is provided via the Wi-Fi Alliance Miracast™ standard.
Miracast and Intel WiDi provide a consumer focused solution via 802.11n. The wireless
infrastructure channel used for an active client connection is also used to connect to the wireless
display receiver.
The above example is commonly referred to as Single Channel Mode, or SCM. For a business
enterprise environment a few adjustments are needed: Autonomous Group Owner for the session is
transitioned to the receiver, Different Channel Mode (DCM) on the client to allow for two simultaneous
wireless networking sessions on different channels, security on the client to isolate wireless LAN from
wireless PAN, wireless channel selection on the wireless display receiver, and more.
Intel® Pro Wireless Display
Implementation Guide
Page 9 of 52
For an enterprise business environment, multiple wireless infrastructure access points often exist
across multiple wireless channels to provide a seemingly always connected experience for mobile
systems. Unlike a consumer wireless environment, an enterprise wireless infrastructure has access to
a larger number of wireless channels in the 5 GHz spectrum, including Dynamic Frequency Selection
(DFS) channels which are prohibited in a Direct Wi-Fi usage model. The Intel Pro WiDi solution
accommodates for these additional requirements.
Instead of sharing the same wireless band and channel as the wireless infrastructure, the Intel Pro
WiDi experience for a business enterprise environment enables the wireless display receiver to be the
Wi-Fi-Direct group owner, commonly referred to as Autonomous Group Owner (AGO). In this model,
the client system must support Different Channel Mode (DCM) to allow two discussions on separate
wireless channels.
Separately from the wireless connectivity changes, Intel Pro WiDi provides improved security and
manageability for Enterprise IT environments. The security enhancements include isolation between
infrastructure (i.e. Wireless LAN) and Wi-Fi-Direct (i.e. Wireless PAN) connections and ensuring only
wireless display communications are occurring on the Wi-Fi-Direct session. Manageability
enhancements include access to settings within the wireless display receiver to customize options

Implementation Guide
specific to the target environment.One benefit of the Intel Pro WiDi architectural changes is the
enabling of an important functional use case: Managed Meetings. With Intel Pro WiDi, up to 16 client
devices can be connected to the wireless display receiver device with presenter controls to determine
which device is shown on the external display. In this scenario, each of the participating clients may
be on a different wireless infrastructure connection, but all are connected to the same Wi-Fi channel
as defined by the Intel Pro WiDi receiver depicted in the following diagram.
1.5
Before you Begin
If new to Intel Pro WiDi, please review the quick start guides or Intel Pro WiDi user guide for more
details on basic setup and use of the solution.
The prior sections provide a foundational understanding on the capabilities of Intel Pro WiDi. In
preparation to deploying Intel Pro WiDi, start with a simple test environment based on the three main
components of Intel Pro WiDi:

Utilities to Assess Existing Microsoft Windows Client Devices
To help in assessing a Microsoft Windows Client for Intel Pro WiDi compatibility two utilities are
available: Intel WiDi Compatibility Checker Tool and Intel Platform Discovery Tool.
2.5.1
Intel WiDi Compatibility Checker Tool
The Intel WiDi Compatibility Tool4, analyzes a client system and provides a summary answer. This
utility requires an internet connection when assessing the client device to query an online database.
2.5.2
Intel Platform Discovery Tool
Intel Platform Discovery tool5, generates an XML file output that can be imported into reviewed by a
client management solution to determine next steps. This utility queries for several Intel hardware
features specifically enabled for enterprise client devices, including Intel Pro WiDi. This utility runs
independently of a network or internet connection.
To use the utility:
1.
2.
3.
Download the tool and extract to a c:\Temp on the client
Open a command prompt using Run as Administrator for the required elevated rights
Run the command: PlatformDiscovery.exe > file.xml
4 Intel WiDi Compatibility Tool available at http://downloadmirror.intel.com/25025/eng/CompatibilityChecker.exe
5 Intel Platform Discovery tool available at https://downloadcenter.intel.com/download/24667

4.
Open the resulting file.xml and scroll to the final section of the output.
In the example output shown below, the platform meets the minimum requirements per the following
data points.
o Intel WiDi application (i.e. WiDiapp.exe) installed is version 6.0.621
NOTE: The application installation checks platform requirements. If the application with appropriate
version number is already present, the platform is known to be Intel Pro WiDi compliant
o Intel Dual Band Wireless 7260 with driver 18.20.0.9
o Intel HD Graphics with driver 10.18.14.4264
o Microsoft Windows 8.1 64-bit
The collected information identifies the current state of the client device. Comparing the data to the
minimum and recommended versions will help identify if and where updates are needed.
2.6
Updating Drivers and Software
If a driver or application update is needed, choose one of the following sources for downloads:
1.
2.
OEM platform downloads meet or exceed the suggested minimums.
Intel generic drivers and software packages via Intel Download Center
The recommended option is to obtain and install drivers provided by the OEM which meet the
minimum requirements for Intel Pro WiDi.
If the OEM drivers do not meet the minimum requirements, Intel generic drivers and software can be
obtained from the Intel Download Center.
The Intel WiDi Update Utility6 is often not preferred for business environments. It is intended for a
consumer user with permissions to install software and drivers on their system. Enterprise policies
often prevent end users ability to accomplish this. In addition, most PC manufacturers have a
customized graphics driver. Intel recommends IT managers refer to OEM drivers first. If an IT
managers chooses to use the latest graphics drivers found on Intel.com, the existing OEM customized
drivers must be removed.
More information on silent installation of the drivers and application is available via Appendix A.

3.1
Area of Responsibility
Those responsible for the conference room environment will be intimately familiar with the room
build out such as ports and connections, conference room displays, whether video scalers are present,
and so forth.
3.2
Specific items to know about Intel Pro WiDi
Intel Pro WiDi requires a receiver, either an adapter connected or capability integrated into the
conference room display device. If the adapter supports remote management, either a network or
wireless infrastructure connection is required along with a centralized remote management console.
The power, network, and video connections, along with placement of the adapter, in the room are the
focuses of this role.
Some Intel Pro WiDi receivers include a USB port. The advanced USB-over-IP (UoIP) or User Input
Back Channel (UIBC) capabilities of the adapter are used for touch screen displays or other
compatible USB Hardware input devices.
These factors will need to be considered by those responsible for conference room environments.
Please refer to your preferred Intel Pro WiDi receiver vendor for additional details on USB connected
devices for the adapter.
3.3

Network Infrastructure
4.1
Area of Responsibility
This role focuses on wireless network infrastructure and management of network devices. The
individuals involved are intimately familiar with the wireless channel spectrum utilization in the
environment and how to fine tune the environment to ensure a great connectivity experience.
4.2
Specific items to know about Intel Pro WiDi
Specific to Intel Pro WiDi, this individual will define the initial configuration settings, handle remote
management of the wireless display receivers and help to ensure a great wireless display experience.
As mentioned in Section 1.3, Intel Pro WiDi is built upon the Miracast standard. Communications
occur via 802.11n between the transmitting client device and the wireless display adapter. The
wireless display adapter is the Autonomous Group Owner (AGO) and include the ability of wireless
channel selection. The transmitting client device supports Different Channel Mode (DCM), enabling
two separate wireless network associations on different wireless channels whether in the 2.4 GHz or 5
GHz band.
Reference the receiver vendor documentation for details how to access and adjust network related
setting.
As a reference for wireless infrastructure best practices, please reference the associated IT@Intel
White Paper7

Remote Management of the Intel Pro WiDi Adapter
Please contact your wireless display adapter vendor regarding their ability to support remote
management and the associated network infrastructure requirements.
4.4
Wireless Infrastructure Assessment
When planning the placement and configuration of the Intel Pro WiDi adapter for the environment,
consider the infrastructure wireless utilization. The wireless display receiver can be set to any nonDFS8 channel in the 2.4 GHz or 5 GHz band.
A variety of wireless infrastructure assessment tools are available for 802.11 a/b/g/n/ac networks.
This document references inSSIDer by MetaGeek, a simple tool that shows wireless network beacons.
For a complete assessment of wireless network saturation or full spectrum analysis, additional tools
may be available to you.

Intel® Pro Wireless Display
Implementation Guide
Page 23 of 52
An example enterprise wireless environment with an Intel Pro WiDi receiver is shown below. The
assessment should occur near the location of the Intel Pro WiDi adapter.
The receiver SSID is labeled DIRECT-xyDDE582 in this example. Actiontec ScreenBeam Business
Edition adapters will commonly be shown via wireless beacons with DIRECT-xyXXXXXX, where the
last 6 characters are unique per adapter. This wireless beacon label is not reflective of the wireless
display receiver names seen by the users when scanning for devices via the Intel Pro WiDi application.
When a specific SSID is selected in the inSSIDer tool, additional information is shown:
The following guidance is provided based on these example screens in regards to Intel Pro WiDi:





The wireless display receiver operates on 802.11n with WPA2-Personal security which
includes CCMP-AES encryption
Link score, as defined by inSSIDer, is a grade for each network calculated by its signal
strength, channel power, and number of networks competing for airtime. With a range of 0100, the higher the value the better.
Co-Channel, as defined by inSSIDer, indicates other access points on the same wireless
channel. Each access point will negotiate when to transmit signal. The more access points
on the same channel, the slower the overall performance for every connected device. For
Intel Pro WiDi, a value of 10 or less is recommended. The actual value will vary based on the
number of client devices connected to co-channel networks and their respective level
network activity, which is beyond the capabilities of the inSSIDer utility to determine.
Overlapping channels should be avoided. As defined by inSSIDer, this refers to stations or
access points on overlapping channels or frequencies. This causes transmission corruption
and slows performance for connected devices. Overlapping channels have a more severe
impact on performance than co-channel networks. Overlapping channels are common in
the 2.4GHz band when access points are set to channels beyond 1, 6, and 11. This is also a
reason to set the Intel Pro WiDi adapter to a channel in the 5 GHz band.
Signal refers to the RSSI (Received Signal Strength Indication) of the wireless access point.
For quality wireless communications, a signal strength of -67 dBm or better is recommended.
In this example, a value of -35dBm indicates a strong signal.

Additional observations from the inSSIDer tool in regards to Intel Pro WiDi:


4.5
Dynamic Frequency Selection (DFS) channels exist only in enterprise wireless infrastructure
and cannot be used for wireless display. The list of DFS channels will vary by country. 9
Intel Pro WiDi uses standard 20 MHz range within a channel, commonly referred to as
standard. Wide channels are common in the 5 GHz spectrum, using a 40 MHz range and
shown as two channels together such as 149+151.
Select an Appropriate Wireless Channel for Intel Pro WiDi
The following screenshot shows the Actiontec Configuration Settings page via a web browser, which
can be accessed via an active wireless display session if the appropriate address and credentials are
used.
NOTE: The wireless channels shown apply primarily to North America. The available wireless
channels may differ in other countries and regions.
Please check with your preferred Intel Pro WiDi receiver vendor for a similar setting capability.
9 For a list of DFS and related wireless network channels, see http://en.wikipedia.org/wiki/List_of_WLAN_channels
Intel® Pro Wireless Display
Implementation Guide
Page 25 of 52
As a reference in selecting a channel, the following example inSSIDer snapshot is provided:
In this example, wireless channels 149, 151, or 165 would be good candidates for the following
reasons:




Use a 5 GHz channel for the Intel Pro WiDi receiver. The 5 GHz spectrum, especially the
higher channels, is often not used for corporate wireless due to signal penetration. An Intel
Pro WiDi session will commonly occur within a conference room with the client system less
than 20 meters away and minimal obstructions. This will require connecting client devices
to support dual-band wireless, which is standard on Intel Core vPro platforms.
Use a wireless channel that is non-overlapping. Often the wireless display receiver is set to
default channel 11. Changing to an available 5 GHz band channel is recommended.
DFS channels cannot be selected. For North America, the DFS channels are 52-14010.
If co-channel networks exist, ensure other access points are separated by at least 20 dBm
The lower 5 GHz band, channels 36-48, would also be good candidates in this example.
With the enterprise wireless network dynamically adjusting based on users and devices, a reassessment of the environment at different times or weekdays may be needed to determine the
appropriate channel per Intel Pro WiDi adapter.

4.6
Conference Room and Quality of Service Considerations
In a dense conference room environment where multiple Intel Pro WiDi receivers will be in range of
each other, additional considerations may apply. In the example below, 6 conference room are
shown with an Intel Pro WiDi receiver in each room connected to either a flat panel display or
projector. In this example, a client PC in Conference A may see the wireless display receivers in
Conference Rooms A through F. Similarly, the Intel Pro WiDi receivers are set as Autonomous Group
Owners for the Wi-Fi direct sessions and by default will have overlapping wireless signals.
Intel Pro WiDi supports 802.11e QoS (Quality of Service). The video and audio packets are marked as
AC_VI (video) which enables the transmitter to have priority over other non-QoS packets. QoS only
applies to devices on the same wireless channel.
If infrastructure wireless solutions, such as such as VoIP (Voice over IP) which utilizes 802.11e QoS
setting AC_VO (Voice), are present they will have a higher priority than the wireless display. With a
Wi-Fi over the air PHY data rate above 100Mbps and a wireless display throughput maximum of
10Mbps, approximately 10% of the available wireless network communication on a specific channel is
used by wireless display QoS packets.
Early deployment testing of Intel Pro WiDi indicated that up to 6 wireless display adapters can be in
range of each other on the same wireless channel without causing conflict to the enterprise wireless
infrastructure. If adjustments are needed, a simple solution is to set the wireless display receivers to
separate channels based on channel availability.

Client and Infrastructure Security
5.1
Area of Responsibility
This role focuses on the protection of corporate electronic assets, especially when transmitted by a
device via wireless to a display while connected to the corporate infrastructure. Ensuring the data
being transmitted and the source of that data is protected from intrusion while allowing the intended
functionality is the focus of this section.
5.2
Specific items to know about Intel Pro WiDi
The foundation of Intel Pro WiDi is industry standard Miracast as defined by the Wi-Fi Alliance. Once
established, the Wi-Fi direct session is protected via the WPA2-Personal standard. Transmitted
content can be further protected via High Definition Content Protection (HDCP) version 2.x.
The Wi-Fi-Direct session of Miracast utilizes a wireless personal area network (WPAN). The Miracast
architecture is native to Microsoft Windows 8.1 and 10, when the installed graphics driver supports
Windows Display Driver Model (WDDM) version 1.311. Miracast was also adopted via select Android
based devices. The Microsoft Windows 7 operating system does not natively support Miracast,
requiring an extension to the operating system that is provided via Intel My Wi-Fi Technology in the
Intel PROset Wireless Software.
The WPAN session is established similar to a wireless infrastructure session. The Intel Pro WiDi
receiver is the Autonomous Group Owner (AGO) to define the wireless session parameters including
wireless channel and session security. The Intel Pro WiDi receiver also includes a DHCP server with a
defined TCP\IP address scope. The sequence in establishing a session is summarized below:
1.
2.
3.
4.
5.
6.
7.
Scan for available wireless display receivers.
User selects the target receiver.
Peer to peer session occurs via Wi-Fi Direct.
DHCP lease reply\request occurs via UDP ports 67/68. The IP address of the receiver and
the DCHP scope are customizable.
An IP address is assigned to the wireless personal area network of the client system, a
Miracast RTSP (Real Time Streaming Protocol) determines the systems capabilities between
the transmitting client and receiving wireless display adapter.
Simple Service Discovery Protocol (SSDP) on multicast port 1900 occurs to determine the
USB-over-IP capabilities of transmitting client and receiving wireless display adapter.
Intel Pro WiDi session is established using the Miracast protocol on TCP port 7236.

Common Enterprise Security Settings to allow Intel Pro WiDi
A comprehensive list of all enterprise security solutions that may need adjustment to allow Intel Pro
WiDi is beyond the scope and purpose of this document. Three common areas of focus include:
1.
2.
3.
The pairing method between transmitting and receiving devices.
Enterprise security policies to allow hosted networks for the WPAN.
Client security or wireless supplicant settings to allow only wireless display via the WPAN
Using the foundation guidance of the previous sections on how wireless display operates, the
following sections focus on specific focus points. If additional guidance is needed, please contact the
receiver vendor.
5.4
Select an appropriate pairing sequence
The initial pairing between the transmitter and receiver devices is via Wi-Fi Protected Setup (WPS)
with a preference for PIN entry by the user. The default setting is a dynamic PIN shown on the
conference display that must be entered by the user. An alternative option is a static PIN that is not
shown on the display but must be known and entered by the user. Pairing between the client
transmitter and the wireless display receiver can also occur via an automated push button
configuration (PBC) to simplify the initial connection experience, if enabled by transmitting client and
receiver devices.
The Intel Pro WiDi pairing process will create a display device on a Microsoft Windows client. The
pairing process occurs only once. Once pairing has completed, subsequent connections utilize the
device setting for future wireless display sessions. If the security settings of the wireless display
receiver are changed, the device must be removed from the Microsoft Windows client and the pairing
process restarted.
Intel® Pro Wireless Display
Implementation Guide
Page 29 of 52
5.4.1
Dynamic PIN
The default and preferred approach is a dynamic PIN that is shown via the Intel Pro WiDi receiver at
the top of the external display.
5.4.2
Static PIN
If displaying the PIN is not preferred, use a static PIN. A static PIN is defined via the configuration
settings of the wireless display receiver and must be known by those wanting to pair to the receiver.
In the following example, the static is 12345670. The PIN can be changed by the administrator.
NOTE: If the PIN Generation Method is changed from Random to Static, all client devices previously
paired to the adapter will need to remove the virtual display device and restart the pairing process
due to the security setting change of the receiver.
Page 30 of 52
Intel® Pro Wireless Display
Implementation Guide
When a client PC initiates a pairing session with the device, the following message will appear and the
user will need to know the static PIN.
5.4.3
Push Button Configuration (PBC)
For simplicity and device interoperability, use push button configuration (PBC). This is the default
option for Microsoft Windows 8.1 systems supporting wireless display and will allow for specific
Android devices that support Miracast to connect. If Microsoft Windows devices have already paired
to the receiver before changing this setting, the display device on the client must be removed and
repaired after the change.
Reference the wireless display receiver user manual for more information on how to enable this
feature.

5.5
Microsoft Active Directory Group Policy Setting for Wireless
Display
Microsoft Active Directory Group Policy settings must allow for Wi-Fi direct communications.
Microsoft Windows 7 systems are impacted if Hosted Networks are not allowed. Microsoft Windows
8.1 and 10 systems are impacted if Wi-Fi Direct Groups are not allowed.
5.5.1
Domain Group Policy Settings
On a Microsoft Windows Server 2008 R2 or higher, the domain group policy for wireless network
security must allow for Hosted Network and Wi-Fi Direct Groups. The options for Don’t Allow
Hosted Networks and Don’t Allow Wi-Fi Direct Groups must be unselected
Page 32 of 52
Intel® Pro Wireless Display
Implementation Guide
5.5.2
Validate Resultant Domain Group Policies on the Client
To ensure the latest domain group policies have been applied to the client system, run gpupdate.msc
To validate the resultant set of policies applied to the client, run rsop.msc
The client system will check all domain enforced policies and show a screen similar to the Group
Policy Editor shown previously. The difference is that resultant policies are read only on the client.
Navigate to the Wireless security settings to validate that Host Networks and Wi-Fi Direct groups are
allowed.
5.5.3
Addressing Common Concerns to Allowing Hosted Networks
Hosted networks must be allowed for Microsoft Windows 7 client to participate in a wireless display
session. Foundational information on Hosted Networks is available via Microsoft MSDN12. Enabling

or disabling of hosted networks does not impact wireless display on Microsoft Windows 8.1 or 10
clients.
Security tools outside the scope of this implementation guide can help to identify and remediate
client systems of concern, and still allow for hosted networks to be enabled.
There are two main components to a wireless hosted network within the Microsoft Windows 7
operating system:


Virtualization of a physical wireless adapter
Software-based access point (“Soft AP”) that is disabled by default
A common, and valid, concern is that the hosted network will be started and the specific wireless
connection settings will be known to others. As a reminder, adjusting the settings and starting the
“Soft AP” requires local administrator. If the hosted network is started and active, it will appear as an
independent access point in the enterprise environment. If the system is rebooted or resumes from
sleep, the hosted network status will reset to “not started”.
In consideration of the timeframe and environment when wireless hosted networks was introduced, a
few environmental items have changed. Users have mobile hotspots, often via a smartphone which
may be connected via USB to a client system and effectively bypass the intended reason of disabling
hosted network. Wireless is more pervasive and sharing via wireless hosted networks may be less of
a requirement. An independent wireless access point in a corporate environment with wireless
network monitoring tools will often be seen as a rogue access point with associated measures to
isolate. Plus, as a reminder, starting the hosted network requires local administrative access which
changes the security perspective of allowed user access or other potential attack surfaces.

Client Firewall and Intrusion Prevention Settings
This subsection identifies the client firewall and intrusion prevention settings to allow for Intel Pro
WiDi session. These settings commonly occur via an administrative console of the client security
solution for the enterprise

This role focuses on the troubleshooting of events that may impact user productivity. Specific to
Intel Pro WiDi, this individual helps to isolate and possibly resolve wireless display issues when
needed. When needed, this individual will engage peer teams for PC lifecycle, Conference Room and
Facilities, Network Infrastructure, or Security to assist in resolving a situation. In addition the
guidance of this implementation guide, this individual may contact a specific component vendor of
the Intel Pro WiDi solution for further assistance.
6.2
Specific items to know about Intel Pro WiDi
There are three main components associated to Intel Pro WiDi: client system (transmitter), wireless
display adapter (receiver), and the conference room display. The Intel Pro WiDi experience is
impacted when one or more components is not configured correctly or the target environment is
disrupting the Wi-Fi direct communication.
A common approach to troubleshooting Intel Pro WiDi is to isolate what solution component or
environment scenario may be impacting the overall solution. Review of the prior sections will assist
in this process. When needed, contact the specific vendor of the transmitter or receiver device.
When needed, assess changes to the environment to allow for wireless display.
6.3

NOTE: VPN solutions often create a virtual network interface and redirect all network communications
resulting in disruption to wireless personal area network (WPAN). If disabling or removing the VPN
client restores wireless display, contact the VPN vendor for additional guidance.
NOTE: If wireless display is successful after disabling, refer to section 5.6 to determine security
adjustments that allow wireless display and maintain security.
6.3.2
Receiver Device Assessment
A complete Intel Pro WiDi experience requires an Intel Pro WiDi certified receiver. Common
differences between a consumer and business wireless display receiver include:



Branding and certification that the receiver is Intel Pro WiDi.
An Intel Pro WiDi receiver is seen via Wi-Fi beacon scanners. (See section 4.4)
Either local or remote management options exist to adjust receiver settings.
Ensure the receiver device is updated to the current firmware release.
For additional assistance, please contact the receiver vendor.
6.3.3
Environment Assessment
If the considerations for transmitter and receiver have been completed, use the same devices in a
different environment. For example, if issues are occurring in a meeting room, re-test the equipment
in a different building or location. Review sections 4.4 through 4.6. If needed, contact your receiver
vendor regarding remote management options.
If the pairing sequence or security settings of the wireless display receiver(s) changed, the associated
virtual display device on the client systems will need to be removed and the pairing process restarted.

When a driver or application is needed for an Intel Pro WiDi client system, the OEM provided package
is commonly a self-extracting installation wizard with no apparent silent or scripted options
applicable to software delivery solutions. Most OEM packages can be extracted to expose the
underlying folder\file structure for the Intel HD graphics and Intel PROset\WLAN driver packages. If
the driver updates are obtained via Intel Download Center, a similar folder\file structure will occur.
The Intel WiDi application is a single executable.
The preferred source for updates is from the OEM.
This section of the document provides guidance how to use the silent installation commands
associated to the driver and application. A complete explanation how to re-package the installer for
distribution across several clients systems is beyond the scope of this document.
7.2
Silent Installation of the Intel Generic Graphics Driver
Using the extracted files, run setup.exe -? to see the command-line options of the Intel Graphics
package installation.
Running the command setup.exe –s –overwrite will silently install the driver, overwriting existing Intel
graphics drivers and suppressing the system reboot. A reboot is recommended once all driver and
software updates have completed.
7.2.1
Overwriting OEM driver via silent installation
NOTE: An OEM driver update is preferred. If the OEM provided graphics driver does meet
recommend minimum versions, testing with an Intel generic driver will require removal of the OEM
platform optimized driver.
If an OEM customized driver is present, the driver from Intel Download Center will fail to install with
reference to incompatible platform. An additional step is required. Using the downloaded and
extracted Intel graphics package, first run setup.exe –uninstall –s. Once that completes, then run

setup –s –overwrite. This sequence will remove the OEM driver, install the Intel driver, and allow for
the network driver package installation to occur before rebooting the client system.
7.3
Silent Installation of Intel PROset package and driver
To create a silent installation package, the Intel PROset/Wireless Software and Drivers for IT
Administrators is required, available at http://www.intel.com/support/wireless/wtech/prosetws/sb/CS-034038.htm. The file downloads will be in ZIP format instead of single installation EXE
format. The recommended package version for Intel Pro WiDi support is 17.14 or higher.
7.3.1
Intel Wireless driver for Microsoft Windows 8.1 and 10 platforms
Microsoft Windows 8.1 and 10 platforms only require the appropriate Intel Wireless LAN Driver as WiFi-Direct and wireless display is native to the operating system. The Intel PROset software extensions
are not required.
Access the Intel PROset/Wireless Software and Drivers for IT Administrator webpage as indicated
above, specifically for version 18.20 or higher. In the file download area, the specific file for 32-bit
platforms will be Wireless_ (Version) _De132.zip. The specific file for 64-bit platforms will be
Wireless_ (Version) _De164.zip. The extract file downloads will include only the wireless drivers.
7.3.2
Intel PROset and Wireless driver for Microsoft Windows 7 platforms
Intel PROset/Wireless software package is required for Microsoft Windows 7 platforms, specifically
the Intel PROset Package Wireless Software Extensions to enable Wi-Fi direct along with the Intel
Wireless LAN driver.
Access the Intel PROset/Wireless Software and Drivers for IT Administrator webpage as mentioned
earlier, specifically for version 18.20 or higher. In the file download area, the specific file for 32-bit
platforms will be Wireless_ (Version) _Win32.zip. The specific file for 64-bit platforms will be
Wireless_ (Version) _Win64.zip. These downloads include the complete Intel PROset installation.
Extract the downloaded ZIP file specific to the target operating system. Advanced configuration
options as referenced in Appendix B require the Intel PROset Administrator Tools on one client
system and can be selected by manually executing setup.exe.

To see the available silent installation options, run setup.exe -?
For silent installation of Intel PROset and wireless drivers on a Microsoft Windows 7 client use:
setup.exe –s -norestart
7.4
Silent Installation of the Intel WiDi application
Version 6.x or higher of the Intel WiDi application is recommended for Intel Pro WiDi.
The downloaded file is setup.exe and be used on either 32-bit or 64-bit platforms.
To see available silent installation options, run setup.exe -?
An example silent installation of the Intel WiDi application with option to disable Windows desktop
shortcut icons is shown below:
Setup.exe /s /v/qn /V“WIDIAPP_DESKTOP_SHORTCUT=0”
NOTE: The Windows desktop icon may be preferred for Windows 7, as the wireless display
connection occurs via the Intel WiDi application. In Microsoft Windows 8.1 or 10 environments,
clicking the connect option in the Intel WiDi application initiates a shortcut key to complete the
connection via the operating system.

Administrator Control
8.1
Introduction
Intel PROset Software Extensions are required for Microsoft Windows 7 clients. In addition to the
software extension, an administrator profile can be defined to restrict usage Wi-Fi Direct
communications.
A single PROSet package will be defined using Intel PROSet administrator tool to apply wireless
display session security options. Once defined on the administrator or reference system, the resulting
package can be applied to other client systems by running the saved executable file on each client.
Wireless display security settings that can be defined by Intel PROset administrator and applied to
Microsoft Windows 7 clients include:





Restrict the Wi-Fi direct session to only Intel WiDi connections
Isolate the personal area network (PAN) from infrastructure wireless LAN (WLAN)
Allow USB over WiDi functionality
Enable the Intel WiDi session connection indicator
Enable the Intel WiDi connection confirmation
