Configuring the EN-4000’s
802.11 Wireless Card
T
he EN-4000 is the newest member of Encore Networks’ family of routers. It
provides wireless and cabled connections to a local area network (LAN) and to
peripheral devices and remote devices.
The 802.11 wireless card was installed in the internal card slot (also called the
embedded card slot) before the EN-4000 was shipped. Place the EN-4000 in its
network location, and attach antennas to the ports labeled MAIN 1 and AUX 1, to
support the internal wireless card. (For details, see the EN-4000™ Quick Installation
Guide.) The EN-4000 supports 802.11a, b, and n wireless protocols.
After logging in to the EN-4000 Management System, follow the procedures in this
discussion to configure the EN-4000’s wireless card as a wireless access point or as a
wireless client.
Note: For additional details of EN-4000 configuration, see Configuring General
Settings for the EN-4000.
11.1 Configuring the 802.11 Wireless Card for the
Network
The EN-4000’s 802.11 wireless card can use one of two operating modes:
• It can function as an access point. See Configuring the 802.11 Wireless Card as
an Access Point, on page 2.
• It can function as a wireless client. See Configuring the 802.11 Wireless Card as
a Wireless Client, on page 10.
Note: A single wireless card can support only one mode at a time.

11.1.1 Configuring the 802.11 Wireless Card as an
Access Point
To configure the 802.11 wireless card as an access point, use the steps in the
following procedure.
1
On the EN-4000 Management System, select the Networks tab; then select
the Wifi tab.
❖ If the EN-4000 contains a wireless card, the Overview Screen for Wireless
Configuration is displayed (Figure 11-1).
This screen provides basic information about the card’s wireless
specifications; it displays the MAC ID and supported versions of 802.11 (in
Figure 11-1, 802.11abgn). If the wireless card has already been
configured, the display also lists the card’s mode and related specifications.
Figure 11-1. Overview Screen for Wireless Configuration
2
In the row for the new wireless card, select the Add button.
❖ The Wireless Access Point Initial Configuration Screen is displayed
(Figure 11-2).

Figure 11-2. Wireless Access Point Initial Configuration Screen
Note: Configure the fields in the lower half of this screen first (under the
heading Interface Configuration).
3
Under the heading Interface Configuration, make sure the General
Settings tab is displayed, and do the following:
a For the Mode, select Access Point.
b In the field labeled ESSID, type a name for the access point. (In this
example, that name is EN4KWIFI.)
c Select the box to indicate that the Network is a LAN.
d Leave the field labeled Hide ESSID blank.
e Make sure the box for WMM Mode contains a check mark.
4
Under the heading Interface Configuration, select the Wireless Security
tab.
❖ The Wireless Configuration Screen, Wireless Security, is displayed
(Figure 11-3).
Go to Table
of Contents
Page 11-4

Figure 11-3. Wireless Configuration Screen, Wireless Security
5
On that screen, set the following values:
a Make sure the Encryption is WPA2-PSK.
b Make sure the Cipher is set to Auto.
Note: In auto mode, the cipher uses CCMP (AES). Other protocols, such as
TKIP, might appear in the list, but 802.11n recommends CCMP (AES).
c For the Key field, specify a password for users to gain wireless access
through this Access Point.
6
Under the heading Interface Configuration, select the MAC Filter tab.
❖ The Wireless Configuration Screen, MAC Filter, is displayed (Figure 11-4).

Page 11-5
On that screen, make sure the MAC Address Filter is disabled.
Note: You can enable that filter if you wish to allow or block specific MAC
addresses.
8
In the top portion of the screen, under Device Configuration, make sure
the General Setup tab is displayed. (Note that the Status display is only
for information; it cannot be changed.) Then do the following:
a Make sure the Wireless Network is Enabled. (Do NOT select Disable.)
b Leave the Channel on Auto.
c For Transmit Power, select the maximum value allowed under your region’s
regulations.
9
Under the heading Interface Configuration, select the Advanced
Settings tab.
❖ The Wireless Configuration Screen, Advanced Settings, is displayed
(Figure 11-5).
Figure 11-5. Wireless Configuration Screen, Advanced Settings
10
On that screen, do the following:
a Select the Mode that provides the highest throughput for your region.
802.11n is the preferred mode when it is available.
b Select a range that works well for HT Mode in your area.
Note: If there are few wireless networks in your area, and if all the devices
that will connect to this access point can support 40 MHz, then this access
point can use 40 MHz. If several wireless networks are in the same area,
20 MHz works better.
c Set the Country Code for the country where the device is located (to
conform to regulations for use of frequencies, etc.).

Select the Save & Apply button.
12
When the EN-4000 is configured as an access point, the 802.11 wireless
interface and the LAN interface can be bridged, to allow the user to connect
through Ethernet or through 802.11 wireless. Do the following:
a On the EN-4000 Management System, select Network, then Interfaces.
❖ The EN-4000 Interfaces Screen is displayed (Figure 11-6).

Note: The DHCP server assigns an IP address to each device that connects
to this EN-4000 over a wireless connection or over an Ethernet LAN. (The
DHCP server’s configuration is shown in the lower portion of Figure 11-7.)

Open a device that will use this access point to reach the wireless network.
That can be any mobile or static device with 802.11 wireless capability. Use
that device’s system to connect to the wireless access point.
Note: If you are connecting another device to this access point, that device
must be an 802.11 wireless client. If that other device is an EN-4000, you
can connect that device to this access point by doing the following on that
EN-4000’s management system:
a Select the Network tab,
b Then select the Wifi tab.
c Then select the Scan Button.
❖ A list displays 802.11 wireless networks within range.
d In that list, find the access point’s network and select Join Network.
Note: For details, see step 1 through step 3 and Figure 11-14 and

Figure 11-13. EN-4000 as Wireless Client
To configure the wireless card as a client, you must first identify the wireless
access point that the wireless card will connect to. That access point must support
the type of 802.11 wireless transmission that the EN-4000 supports (802.11a,
802.11b, 802.11n; or combined support for 802.11a+n). You must also know the
password (and other credentials, if applicable) to log on to that access point.
