On the add WDS screen, enter the MAC address of the access point, up 
to 4 APs can be added to the AP MAC Address table, and click Apply. 
Here is an example of how to setup two units of 3Com Router over WDS. 
Note that when setting up two units of 3Com Router, you should disable 
the DHCP function on one of the units.
Setting of the first Router: 
■Set the LAN IP setting, make sure the DHCP function is enabled on this 
Router. 
■Set the wireless settings, including SSID, channel, and wireless mode.
■Set the wireless security setting, and enable wireless WDS function. 
Setting of the second Router: 
■Set the LAN IP setting, use a different IP address from the IP address of 
the first Router. Disable the DHCP function, this would allow the first 
Router to allocate IP address for wireless clients. 
■Set the wireless channel, and security same as the first Router, but use 
a different SSID. Make sure that WDS function is enabled. 
Access the Web UI of the first Router, use wireless WDS settings screen, 
make sure that WDS is enabled. Click Rescan Wireless Networking to 
scan the available APs in your area, you should see the SSID of the second 
Router. Check and add the second Router to the WDS table (see 
Figure 52).

AdvancedThe Advanced screen allows you to configure detailed settings for your 
wireless connection. Please note that you should not change this settings 
unless you are an expert user. There are six parameters that you can 
configure:
Figure 54   Wireless Advanced Setting Screen 
■Beacon Interval: this represents the amount of time between beacon 
transmissions. 
■DTIM Interval: A DTIM (Delivery Traffic Indication Message) is a 
countdown mechanism used to inform your wireless clients of the 
next window for listening to broadcast and multicast messages.
■Fragmentation Threshold: this is the maximum size for directed data 
packets transmitted. The use of fragmentation can increase the 
reliability of frame transmissions. Because of sending smaller frames, 
collisions are much less likely to occur. 
■RTS Threshold: RTS stands for Request to Send, this parameter 
controls what size data packet the low level RF protocol issues to an 
RTS packet.
■CTS Protection Mode: CTS stands for Clear to Send. CTS Protection 
Mode boosts the Router’s ability to intercept 802.11b/ 802.11g 
transmissions. Conversely, CTS Protection Mode decreases 
performance. Leave this feature disabled unless you encounter severe 
communication difficulties between the Router and your wireless 
clients.
■AP Isolation Mode: AP Isolation is a function to prevent wireless clients 
connected with the device from communicating with one another. 
When enabled, this creates a separate virtual network for your 
wireless network, each of your wireless client will be in its own virtual

may want to utilize this feature if you have many guests that 
frequently connect to your wireless network.

There are five options available for the connection mode:
■Dynamic IP — Using DHCP for WAN connection (see page 74)
■Static IP — Using fixed IP for WAN connection (see page 75)
■PPPoE — PPP over Ethernet, providing routing for multiple PCs (see 
page 76)
■PPTP — Point-to-Point Tunneling Protocol (see page 77)
■L2TP — Layer 2 Tunneling Protocol (see page 78)
