2.2 Preparing the Networking
This chapter covers the things that need to be done before configuring the router. The first thing is
to set all computers on the network for TCP/IP networking and also gather necessary information
from the Internet Service Provider (ISP).
2.3 Collecting ISP Information
The following information needs to be gathered from the ISP before configuring the router:
․IP Assignment from ISP: Are IPs assigned dynamically or you have a fixed IP address? If fixed,
what are the IP address, Subnet Mask, Default Gateway as well as the DNS addresses for this
account?
․Connection Type: Is this a PPPoE or PPTP connection? If PPPoE, what are the username and
password associated with this account? If PPTP, the server IP address as well as user
authentication information is required.
Please contact your ISP if you’re not sure of the answers to these questions.
2.4 Configuring Windows for IP Networking
Each computer on the network and connecting to the router should be configured for TCP/IP
networking. The router is by default a DHCP server and if you plan to use DHCP (recommended).
Each computer must be configured to receive an IP address automatically. See the procedure
below.
If fixed IP addresses are to be used on the network, you’ll need to manually assign an IP address
to each computer and make sure that they are in the same subnet as the router. Refer to your
Windows documentation for instructions on IP assignment.







Authentication Type: The router supports three kinds of the authentication typesOpen System, Shared Key, and Auto.
Fragment Threshold: Fragmentation mechanism is used for improving the
efficiency when traffic is high in the wireless network. If a wireless client often
transmits large files, you can enter new Fragment Threshold value to split the
packet. The value can be set from 256 to 2346. The default value is 2346.
RTS Threshold: RTS Threshold is a mechanism implemented to prevent the
“Hidden Node” problem. “Hidden Node” is a situation in which two stations are
within range of the same wireless access point/router, but are not within range of
each other. Therefore, they are hidden nodes for each other. When a station starts
data transmission with the Wireless-G Router, it might not notice that the other
station is already using the wireless medium. When these two stations send data
at the same time, they might collide when simultaneously arriving at the
Wireless-G Router. The collision will most certainly result in loss of messages of
both stations. If the “Hidden Node” problem is an issue, please specify the packet
size. The RTS mechanism will be activated if the data size exceeds the value you
set. The default value is 2347.
Beacon Interval: Beacon interval is the amount of time between beacon
transmissions. Before a station enters power save mode, the station needs the
beacon interval to know when to wake up to receive the beacon (and learn
whether there are buffered frames at the wireless router).
Data Rate: By default, it selects the highest rate for transmission.
Preamble Type: A preamble is a signal used in wireless environments to
synchronize transmit timings including Synchronization and Start Frame Delimiter.
In a “noisy” network environment, Preamble Type should be set to Long. The
Short Preamble is intended for applications where minimum overhead and
26

maximum performance is desired.
Broadcast SSID: When enabled allows all wireless stations to detect the SSID of
this wireless router.
IAPP: The Inter-Access Point Protocol (IAPP) can extend multi-vendor
interoperability to the roaming function.
802.11g Protection: Is used to prevent packet collision and increase
performance in wireless networks with both 802.11b (using CCK modulation) and
802.11g (using OFDM modulation) devices.
WMM: The short of Wi-Fi Multi-Media. It will enhance the data transfer
performance of multimedia content when they are being transferred over wireless
network. If you do not know what it is / not sure if you need it. It’s safe to set this
option to “Enable”, however, default value is “Disable”.
RF Output Power: Output power can be set of wireless radio. Unless you are
using this wireless router in a really big space. You may not have to set output
power to 100%. This will enhance security.
Turbo Mode: The data rate will up to 72Mbps when the turbo mode is enabled.
Please be noted the turbo mode might have compatibility issue when be used
without Realtek solution.
Apply Changes: Click on “Apply Changes” to save the setting.
Reset: Click on “Reset” button to undo your changes.

3.3.3 Security
Here users define the security type and level of the wireless network. Selecting different methods
provides different levels of security. Please note that using any encryption may cause a
significant degradation of data throughput on the wireless link. There are five Encryption
types supported: “None”, “WEP”, “WPA (TKIP)”, ”WPA2(AES)”, and “WPA2 Mixed”.

No Encryption Used





Encryption: “None” means no encryption used. Users can enable 802.1x
Authentication and enter the RADIUS server parameters – port, IP address and
Password.
Use 802.1x Authentication: Is a port access protocol for protecting networks via
authentication. If wireless user is authenticated (via 802.1x), a virtual port is
opened on the router/access point allowing for communication. If authentication
fails, the router/access point will deny access to the user.
Authentication RADIUS Server: RADIUS is the Remote Access Dial-In User
Service, an Authorization, Authentication, and Accounting (AAA) client-server
protocol, which is used when a AAA dial-up client logs in or out of a Network
Access Server. Typically, a RADIUS server is used by Internet Service Providers
(ISP) to perform AAA tasks. AAA phases are described as follows:

Authentication phase: Verifies a user name and password against a local
database. After the credentials are verified, the authorization process
begins.

Authorization phase: Determines whether a request is allowed access to a
resource. An IP address is assigned for the Dial-Up client.

Accounting phase: Collects information on resource usage for the purpose
of trend analysis, auditing, session time billing, or cost allocation.
Users must enter RADIUS Server’s Port number, IP address and Password.

Encryption: “WPA” stands for Wi-Fi Protected Access. There are three encryption
modes – TKIP, AES and Mixed.

TKIP: Temporal Key Integrity Protocol.

AES: Advanced Encryption Standard.

Mixed: WPA2 Mixed mode operation permits the coexistence of WPA and
WPA2 clients on a common SSID. WPA2 Mixed Mode is a Wi-Fi Certified
feature. During WPA2 Mixed Mode, the Wireless-G Router advertises the
encryption ciphers (TKIP, CCMP, other) that are available for use. The client
selects the encryption cipher it likes to use and the selected cipher is used
for encryption between the client and Wireless-G Router.

Appendix B: Frequently Asked Questions
Q1: What is wireless networking?
Ans: The term wireless networking refers to the technology that enables two or more computers to
communicate using standard network protocols, but without network cabling. Strictly speaking, any
technology that does this could be called wireless networking. The current buzzword however
generally refers to wireless LANs. This technology, fuelled by the emergence of cross-vendor
industry standards such as IEEE 802.11, has produced a number of affordable wireless solutions
that are growing in popularity with business and schools as well as sophisticated applications
where network wiring is impossible, such as in warehousing or point-of-sale handheld equipment.
Q2: What is a wireless network made up of?
Ans: There are two kinds of wireless networks:
a. An ad-hoc, or peer-to-peer wireless network consists of a number of computers each equipped
with a wireless networking interface card. Each computer can communicate directly with all of the
other wireless enabled computers. They can share files and printers this way, but may not be able
to access wired LAN resources, unless one of the computers acts as a bridge to the wired LAN
using special software. (This is called "bridging")
Figure A1: Ad-Hoc or Peer-to Peer Networking.
Each computer with a wireless interface can communicate directly with all of the others.
b. A wireless network can also use an access point, or base station. In this type of network the
access point acts like a hub, providing connectivity for the wireless computers. It can connect (or
"bridge") the wireless LAN to a wired LAN, allowing wireless computer access to LAN resources,
such as file servers or existing Internet Connectivity.
There are two types of access points:
I. Dedicated hardware access points (HAP) such as Lucent's WaveLAN, Apple's Airport Base
Station or WebGear's AviatorPRO. (See Figure A2). Hardware access points offer comprehensive
support of most wireless features, but check your requirements carefully.
ii. Software Access Points which run on a computer equipped with a wireless network interface
card as used in an ad-hoc or peer-to-peer wireless network. (See Figure A3) The Vicomsoft
InterGate suites are software routers that can be used as a basic Software Access Point, and
include features not commonly found in hardware solutions, such as Direct PPPoE support and
extensive configuration flexibility, but may not offer the full range of wireless features defined in the
802.11 standard.
With appropriate networking software support, users on the wireless LAN can share files and
printers located on the wired LAN and vice versa. Vicomsoft's solutions support file sharing using
TCP/IP.

Q3: Can I mix wireless equipment from different vendors?
Ans: Because most wireless networking hardware vendors support the 802.11 standard they can
inter operate. However, we recommend verification as the standard is a fairly recent one, and does
specify two different methods for wireless communications; Frequency Hopping (FH) and Direct
Sequence Spread Spectrum (DSSS or DS), which are not interoperable.
When purchasing wireless networking hardware from separate vendors be sure to obtain
guarantees from the vendors that the hardware will interoperate and follows the standards.
Within a short time we expect all new wireless cards, like Ethernet cards, to become inexpensive,
ubiquitous and totally interoperable.
Also of note is that the latest version of the standard defines 11mbps and 5.5mbps networking,
with support for the older standard 1mbps and 2mbps speeds. This provides some compatibility
with different or older equipment. Note that this new standard covers DS-type Networks, not FH
types.
Software access points such as InterGate which uses the wireless interface of the host computer
should have no compatibility issues with third party wireless hardware, as long as standards are
followed. Typically wireless hardware is identified to the software as a network interface, and
therefore can be used in the same way as any other network card.
Q4:If my computer is connected to a wireless LAN, can it communicate with computers on a wired
LAN as well?
Ans: To do this you will need some sort of bridge between the wireless and wired network. This
can be accomplished either with a hardware access point or a software access point. Hardware
access points are available with various types of network interfaces, such as Ethernet or Token
Ring, but typically require extra hardware to be purchased if your networking requirements
change.
If networking requirements go beyond just interconnecting a wired network to a small wireless
network, a software access point may be the best solution.
A software access point does not limit the type or number of network interfaces you use. It may
66
also allow considerable flexibility in providing access to different network types, such as different
types of Ethernet, Wireless and Token Ring networks. Such connections are only limited by the
number of slots or interfaces in the computer used for this task.
Further to this the software access point may include significant additional features such as shared
Internet access, web caching or content filtering, providing significant benefits to users and
administrators.
Q5: What is Roaming?
Ans: A wireless computer can "roam" from one access point to another, with the software and
hardware maintaining a steady network connection by monitoring the signal strength from in-range
access points and locking on to the one with the best quality. Usually this is completely transparent
to the user; they are not aware that a different access point is being used from area to area. Some
access point configurations require security authentication when swapping access points, usually
in the form of a password dialog box.
Access points are required to have overlapping wireless areas to achieve this as can be seen in
the following diagram:
Figure A6: Roaming.
A user can move from Area 1 to Area 2 transparently. The Wireless networking hardware
automatically swaps to the Access Point with the best signal.
Not all access points are capable of being configured to support roaming. Also of note is that any
access points for a single vendor should be used when implementing roaming, as there is no
official standard for this feature.
Q6: What about security?
Ans: Wireless communications obviously provide potential security issues, as an intruder does not
need physical access to the traditional wired network in order to gain access to data
communications. However, 802.11 wireless communications cannot be received --much less
decoded-- by simple scanners, short wave receivers etc. This has led to the common
misconception that wireless communications cannot be eavesdropped at all. However,
eavesdropping is possible using special equipment.
To protect against any potential security issues, 802.11 wireless communications have a function
called WEP (Wired Equivalent Privacy), a form of encryption which provides privacy comparable to
that of a traditional wired network. If the wireless network has information that should be secure
then WEP should be used, ensuring the data is protected at traditional wired network levels.
Also it should be noted that traditional Virtual Private Networking (VPN) techniques will work over
wireless networks in the same way as traditional wired networks.
Section Two - Wireless Networking and the Internet
Q7: How can I use a wireless network to share an Internet connection?
Ans: Once you realize that wireless cards are analogous to Ethernet cards and that empty space
67
is analogous to Ethernet cabling, the answer to this question becomes clear. To share an Internet
connection across a LAN you need two things:
If your LAN is wireless, the same criteria apply. You need a hardware or software access point and
a wireless LAN. Any computer equipped with a wireless network card running suitable Internet
sharing software can be used as a software access point. (See Figure A8) A number of vendors
offer hardware access points.
A hardware access point may provide Internet Sharing capabilities to Wired LAN computers, but
does not usually provide much flexibility beyond very simple configurations. (See Figure A9)
Figure A8: Software Access Point.
Wireless connected computers using a Software Access Point for shared Internet access.

Q8: How can I secure my wireless home network?
Ans: Here are 3 quick steps to help you secure your wireless network from unauthorized access.
These steps are provided as general guidelines - for detailed help, please contact your hardware
vendor.
1. Change the administrator password.
2. Change your SSID and turn off SSID Broadcasting
3. Enable WEP
Q9: What is Virtual Private Networking?
Ans: Typically, a Virtual Private Network (VPN) is defined as a group of two or more computer
systems connected to a private network with limited public-network access that communicates
securely over a public network, such as the internet: Security experts agree that VPNs include
encryption, authentication of remote users or hosts, and mechanisms for hiding or masking
information about private network topology from potential attackers on the public network:
Q10: What is encryption?
Ans: Encryption is a mathematical operation that transforms data from standard text to cipher text.
Usually the mathematical operation requires that an alphanumeric key be supplied along with the
standard text. The key plus standard text is processed by the encryption operation, which
68
produces secure scrambled text. Decryption is the opposite of encryption; it is the mathematical
operation that transforms cipher text to standard text.
Q11: Why do I need a router?
Ans: The increased reliance on computers to store valuable information and the development of
applications that share information over the internet through networked personal computers, in
combination with the advent of computer hacking, has made information and network security an
important issue. Typical analog modems and/or the higher-speed cable/DSL modems do not
provide the necessary security to prevent someone from hacking into a computer. Having a device
that provides network address translation (NAT) capability provides a simple solution to the
hacking issue.
Q12: What is NAT?
Ans: Network Address Translation is used in a router to prevent hacking into the local area
network (LAN). NAT substitutes a "private" IP address of devices located on the LAN side of the
router with a new "public" IP address that is visible on the internet side of the router. By virtue of
this simple implementation, any of up to 253 devices located on the LAN will be hidden from
internet hackers. Only the router's IP address is visible on the internet.
Q13: Isn't NAT the same as "firewall"?
Ans: No. Though the term "firewall" has been used when describing a router's ability to hide the
LAN IP addresses, a true firewall employs a technology called Stateful Packet Inspection (SPI).
Firewalls provide a greater level of security and are generally more expensive than a NAT router.
Firewalls give the administrator the ability to set up specific IP addresses or domain names that
are allowed to be accessed, while refusing any other attempt to access the LAN. This is often
referred to as filtering. Firewalls can also allow remote access to the private network through the
use of secure login procedures and authentication certificates (VPN). Firewalls are used to
prevent Denial of Service (DoS) attacks and can use software to provide content filtering to deny
access to unwanted web sites.
Q14: Can the Access Point act as my DHCP Server?
Ans: No. The Access Point is nothing more than a wireless hub, and as such cannot be configured
to handle DHCP capabilities.
Q15: Can I run an application from a remote computer over the wireless network?
Ans: This will depend on whether or not the application is designed to be used over a network. See
the application's user guide to determine if it supports operation over a network.
Q16: What is Ad-hoc?
Ans: An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as
an independent wireless LAN. An Ad-hoc wireless LAN is applicable at a departmental scale for a
branch or SOHO operation.
Q17: What is Infrastructure?
Ans: An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure
is applicable to enterprise scale for wireless access to a central database, or wireless application
for mobile workers.
Q18: What is WEP?
Ans: WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40-bit shared-key
algorithm, as described in the IEEE 802.11 standard.
Q19: How do I reset the Access Point or Router?
Ans: Press the Reset button on the back of the Access Point for about ten seconds. This will reset
the unit to its default settings.
Q20: Does the Access Point function as a firewall?
Ans: No. The Access Point is only a bridge from wired Ethernet to wireless clients.
69
Q21: What is the maximum number of users the Access Point facilitates?
Ans: It depends on the volume of data and may be less if many users create a large amount of
network traffic.
Q22: What is the maximum number of IP addresses that the Router will support?
Ans: The Router will support up to 253 IP addresses.
Q23: Where is the Router installed on the network?
Ans: In a typical environment, the Router is installed between the cable/DSL modem and the LAN.
Plug the Router into the cable/DSL modem's Ethernet port.
Q24: Does the Internet connection of the Router support 100Mbps Ethernet?
Ans: The Router's current hardware design supports up to 100Mbps Ethernet on its Internet port;
however, the Internet connection speed will vary depending on the speed of your broadband
connection. The Router also supports 100Mbps over the auto-sensing Fast Ethernet 10/100
switch on the LAN side of the Router.
Q25: Does the Router support any operating system other than Windows 98, Windows Millennium,
Windows 2000, or Windows XP?
Ans: Yes, at this time, provide technical support to setup, configuration or troubleshooting of any
non-Windows operating systems.
Q26: When all else fails in the installation, what can I do?
Ans: Reset the Router by holding down the reset button until the Power LED fully turns on and off.
Reset your cable or DSL modem by powering the unit off and then on. Obtain and flash the latest
firmware release that is readily available.
Q27: I am not able to get the web configuration screen for the Router. What can I do?
Ans :You may have to remove the proxy settings on your Internet browser, e.g., Netscape
Navigator or Internet Explorer. Or remove the dial-up settings on your browser. Check with your
browser documentation, and make sure that your browser is set to connect directly and that any
dial-up is disabled. Make sure that your browser is set to connect directly and that any dial-up is
disabled. For Internet Explorer, click Tools, Internet Options, and then the Connection tab. Make
sure that Internet Explorer is set to Never dial a connection. For Netscape Navigator, click Edit,
Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to direct connection
to the Internet.
Q28: Can the Router act as my DHCP server?
Ans: Yes. The Router has DHCP server software built-in.
Q29: How to use Virtual Server in Wireless/Broadband Router?
Ans: It’s also called Port forwarding. Virtual Server feature allows Internet users to access
standard Servers on your LAN, via the Internet IP Sharer. Normally, Internet users would not be
able to access a server on your LAN because your Server does not have a valid external IP
Address.
Q30: Why Wireless/Broadband Router always has problem under Cable connection but not ADSL
connection?
Ans: For ADSL, one subscriber shares one line. If your ISP provides you a 512K account then you
can enjoy the full 512Kbps on your side. But Cable is different. Many subscribers share the same
line. For example, the bandwidth of Cable is 1.5Mbps. If there are 25 users accessing the Internet
at the same time then the bandwidth of each user is 1500K/25 near 60K. The speed is just like the
traditional modem connection. If there are only 5 users on line at this moment then each user can
share the bandwidth to nearly 300K (1500K/5). So, the speed over ADSL is more stable than
Cable. The access will hang up when the traffic is heavy over the Cable. It is the reason why many
problems only happen over Cable.
