LAN SettingsYour Router is equipped with a DHCP server that will automatically assign 
IP addresses to each computer on your network. The factory default 
settings for the DHCP server will work with most applications. If you need 
to make changes to the settings, you can do so. 
The LAN settings screen allows you to: 
■Change the default IP address of the Router. The default IP is 
192.168.1.1
■Change the Subnet Mask. The default setting is 255.255.255.0
■Enable/Disable the DHCP Server Function. The default is “Enable”.
■Specify the Starting and Ending IP Pool address. The default is 
Starting: 2 / Ending: 254. 
■Specify the IP address Lease Time. The default is One day.
■Specify a local Domain Name. This field is optional. 
■Specify the IP address of 3Com NBX call processor. 
The Router will also provide a list of all client computers connected to the 
Router.
LAN SettingsThe LAN Settings screen is used to specify the LAN IP address of your 
Router, and to configure the DHCP server.

1Enter the Router’s IP Address and Subnet Mask in the appropriate fields. 
The default IP address is 192.168.1.1.
2If you want to use the Router as a DHCP Server, check Enable in the DHCP 
Server field.
3Enter the IP address range in the IP Pool Start Address and IP Pool End 
Address fields.
4Specify the DHCP Lease time by selecting the required value from the 
Lease Time drop-down menu. The lease time is the length of time the 
DHCP server will reserve the IP address for each computer. 
5Specify the Local Domain Name for your network (this step is optional).
6Enter the IP address of the NBX Call Processor in the 3Com NBX Call 
Processor field (this step is optional).
7Check all of your settings, and then click Apply.
DHCP Clients ListThe DHCP Clients List provides details on the devices that have received IP 
addresses from the Router. The list is only created when the Router is set 
up as a DHCP server. A maximum of 253 clients can be connected to the 
Router.
Figure 38   DHCP Clients List Screen 
For each device that is connected to the LAN, the following information is 
displayed:
■IP address — The Internet Protocol (IP) address issued to the client 
machine. 
						

							54CHAPTER 5: CONFIGURING THE ROUTER
■Host Name — The client machine’s host name, if configured.
■MAC Address — The Media Access Control (MAC) address of the 
client’s network card.
■Client Type — Whether the client is connected to the Router by wired 
or wireless connection.
■Check the Fix checkbox to permanently fix the IP address.
■Click Release to release the displayed IP address.
■Click Add to allocate an IP address to a MAC address. Enter the 
required details and click Apply to save your settings.
The DHCP server will give out addresses to both wired and wireless 
clients. 
						

							Wireless Settings55
Wireless SettingsThe Wireless Settings screens allow you to configure the settings for the 
wireless connections.
You can enable or disable the wireless connection for your LAN. When 
disabled, no wireless PCs can gain access to either the Internet or other 
PCs on your wired or wireless LAN through this Router.

							56CHAPTER 5: CONFIGURING THE ROUTER
ConfigurationThe 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:
1Check Enable Wireless Networking checkbox.
2Select the wireless channel you want to use from the Channel drop-down 
menu.
3Select 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. 
4Specify 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.
5Enable or disable SSID Broadcast.
A feature of many wireless network adapters is that a computers 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 
computers 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. 
						

							Wireless Settings57
6Select 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.
7Bandwidth: 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.
8Select 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.”
9Click Apply.
EncryptionThis feature prevents any non-authorized party from reading or changing 
your data over the wireless network.
Figure 41   Encryption Screen 
						

							58CHAPTER 5: CONFIGURING THE ROUTER
Select the wireless security mode that you want to use from the 
drop-down menu, and click Apply. There are five selections:
■Disabled 
■64-bit WEP: (see page 58)
■128-bit WEP: (see page 59)
■WPA-PSK (no server): this option includes both WPA and WPA2 
(see page 60
)
■WPA (with RADIUS Server): this option includes both WPA and WPA2 
(see page 61
)
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.
Figure 42   64-bit WEP Screen
To setup 64-bit WEP:
1You can enter the 64-bit WEP key manually:
■enter the WEP key as 5 pairs of hex digits (0-9, A-F).
