Configuration

The Wireless Configuration Screen allows you to turn on/ turn off the

wireless function, and set up basic wireless settings. you can also

enable/disable the Wireless function using the WiFi on/off button at the

back of the unit.

Figure 40

Wireless Configuration Screen

To enable the wireless function:

1

Check

Enable Wireless Networking

checkbox.

2

Select the wireless channel you want to use from the

Channel

drop-down

menu.

3

Select the Extension Channel. Extension channel is used to increase the

throughput. If the Bandwidth is set to 20 MHz, then this option will not

be available.

4

Specify the SSID to be used by your wireless network in the

SSID

field. If

there are other wireless networks in your area, you should give your

wireless network an unique name.

5

Enable or disable

SSID Broadcast

.

A feature of many wireless network adapters is that a computer's SSID

can be set to ANY, which means it looks randomly for any existing

wireless network. The available networks are then displayed in a site

survey, and your computer can select a network. If you disable this SSID

broadcast function, you can block this random search, and set the

computer's SSID to a specific network (for example, WLAN). This

increases network security. If you decide to disable

SSID Broadcast

, ensure

that you know the name of your network first.

Select whether your Router will operate in 11b mode only, 11g mode

only, 11n mode only, or mixed mode from the

Wireless Mode

drop-down

menu. If your network contains 11b, 11g, and 11n clients, select the

mixed mode. If your network contains just one type of clients only, select

11b only, or 11g only, or 11n only, depending on your wireless network

environment. Note that selecting one type of wireless network only will

improve the performance, however, this will prevent clients of other type

from connecting to the router.

7

Bandwidth: select the bandwidth to use. Select 20/40 MHz when your

wireless mode is 802.11n or 11n with 11b, 11 g mixed mode. If your

wireless network is purely 11 b only or 11g only, or 11b and 11g mixed,

select 20 MHz.

8

Select to turn on/off the

Protected Mode

function. As part of the

802.11g & 802.11n specification, Protected mode ensures proper

operation of 802.11g & 802.11n clients and access points when there is

heavy 802.11b traffic in the operating environment. When protected

mode is ON, 802.11g & 802.11n scans for other wireless network traffic

before it transmits data. Therefore, using this mode in environments with

HEAVY 802.11b traffic or interference achieves best performance results.

If you are in an environment with very little--or no--other wireless

network traffic, your best performance will be achieved with Protected

mode “OFF.”

Disabled

In this mode, wireless transmissions will not be encrypted, and will be

visible to everyone. However, when setting up or debugging wireless

networks, it is often useful to use this security mode.

64-bit WEP

WEP is the basic mechanism to transmit your data securely over the

wireless network. Matching encryption keys must be setup on your

Router and wireless client devices to use WEP. Note that 3Com

recommends using WPA/WPA2 to secure your wireless connection.
