Setup 3Com Wireless LAN Access Point 2000 as a wireless bridge

Depends if you need a wireless or wired bridge?

Here is some info for you.

Infrastructure Mode

With a wireless Access Point, you can operate the wireless LAN in the infrastructure mode. This
mode provides wireless connectivity to multiple wireless network devices within a fixed range or
area of coverage, interacting with wireless nodes via an antenna.

In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet
data, acting as a bridge between the wired LAN and wireless clients. Connecting multiple Access
Points via a wired Ethernet backbone can further extend the wireless network coverage. As a
mobile computing device moves out of the range of one access point, it moves into the range of
another. As a result, wireless clients can freely roam from one Access Point domain to another and
still maintain seamless network connection.


Wireless Bridging Overview
Using Wireless Router as a Wireless Access Point

For 3com type of routers, you must connect firstly to 3com setup, By:
First: open your browser and type 192.168.1.1
Second: you will find adapter setting and reset it, it all depends upon your router's software.
Third: the easiest way is to reset it from the small button in the back of your router.

I'm assuming you have two of these.
Configure one as an access point. Choose a frequency channel, an SSID, a power setting, and an encryption method and password. Set its administrative password. Give it an IP address in the proper range of your LAN, and attach it to your LAN switch. Point it properly.
Configure the other as a bridge or a bridge-router, as you require. Tell it what SSID to find, set its power setting, and give it the same encryption method and password. Set its administrative password. Give it a different IP address in the proper range of your access point's LAN. If you configure it as a bridge-router, configure its own LAN side as you wish. Point it at the remote access point, and within about 30 seconds it should pick up on the signal and you will have a point-to-point network.

CONNECT YOUR ROUTER TO 1 COMPUTER WITH LAN CABLE MEANS ETHERNET CABLE.
then access link
http://192.168.1.1
or
http://192.168.0.1

Key's are usually installed by the one that installed the Wireless, if you are the one that installed it try to login into the router and disable the security or change it.

You need to access the setup page of your Belking router and go to the wireless setup, look fro Use as Access Point, now just a reminder this will defeat the NAT IP sharing feature of the router. Configure the IP address of the router to the same subnet as the network your tying to bridge here's the more detailed procedure:

1. Enable the AP mode by selecting "Enable" in the Use Access Point only page. When you select this option you can now change the IP Settings.

2. Set your IP settings to match your network. Click "Apply Changes"

3. Connect a cable from the LAN port of the router to your existing network.

contact your ISP for proper settings for the router.

The repeater must be the same brand as the signal it is repeating. Different routers / access points work in slightly different ways and the current generation of wireless repeaters aren't smart enough to work with other brands.

It's kind of like trying to put an engine from a Nissan Altima into a Honda Accord... both make the car move but they aren't the same inside.

Usually there is a paper clip sized hole in the back of the WAP that you insert a pin or paper clip into for 10 seconds.

try using predefined IP addresses. Let each pc make it's own IP address and see if the conflicts continue, if they do, post again. :)
