Bridging a Linksys WRT54G and Belkin 7230-4 Wirelessly
These steps will create a wireless bridge between a WRT54G as the Gateway and a 7230-4 as an access point (AP). The AP will act as a repeater (extending the range of your wireless network), as well as an AP. The AP will also act as an ethernet bridge, so you can plug it in to an xbox or ps2 (or a computer with ethernet but no wireless) to gain access to your wireless network. I am writing this because I found many tutorials explaining how to connect two WRT54G's together, but nothing explaining how to connect a Linksys and a Belkin. After trial and error, this is what I came up with:
Step 1) If you are using Linksys firmware, you will have to flash a 3rd party firmware to the WRT54G, such as Sveasoft's Alchemy. I am using dd-wrt, which is a variation of Alchemy. I won't discuss flashing, as it is explained very well on other forums.
Step 2) Now that the firmware is upgraded, you can now establish wireless bridging on the WRT54G. If you haven't messed with the IP settings of the router, use IE to access 192.168.1.1 to get to the web-interface of the router. Go to the "Wireless" tab. In "Basic Settings, change the Wireless channel to 11 (or whatever works for you, but the two units must be on the same channel, the default for Linksys is 6 and the default for Belkin is 11). Click on the "WDS" link on the far right. Change the drop down menu to LAN and type in the WLAN MAC address of the Belkin. Click "Save Settings" button. You are done with the WRT54G.
Step 3) Clear all settings in the Belkin router by pushing in the reset button on the back and holding for 10 seconds. You will see all the lights blink green, then orange, then router will go back to normal with all factory settings.
Step 4) Connect to the 7230-4 with an ethernet cable directly from a computer (do not go from the WRT54G) and plug into one of the blue ports (not the green one). It is helpful if you are doing this on a different computer than the one the Linksys is connected to. You can now access the web-based interface through 192.168.2.1. Click on "Use as Access Point" on the menu at the left, then click "Enable". The new default IP address will be 192.168.2.254. You can change that 254 to whatever you like as long as it's less than 255. Remeber what you set it at, or you will be doing another hard reset. Click "Apply Changes", then change the address in you web browser to the new IP address (e.g. 192.168.2.254).
Step 5) You are now in the web-interface of the AP. Click on "Wireless Bridge" on the menu at the left. "Enable Wireless Bridging" should already be selected. Select "Enable Only Specific Access Points To Connect" as well, and put in the WLAN address of the WRT54G. Note: It is very important to be working with the WLAN address of both units, and NOT the LAN address. Click "Apply Changes". Lastly, make sure that the unit is on the same channel as what you set the Linksys to.
Step 6) Log out of the web-interface and unplug the power to the Belkin, wait a few seconds, and plug the power back in. The two units should now be bridged. To test it out, plug a separate computer into the the Belkin and see if you can access the internet or view files on the computer connected to the Linksys. No computer or other device needs to be plugged into the Belkin for it to be bridged, so it can sit in a closet or something if all you want to do is extend your wireless range.
The only problem I have is that once the Belkin is rebooted and bridged to the Linksys, I can no longer access the web-interface via 192.168.2.254. The only way I can get back into the Belkin is to do the hard reset, make my changes and go through steps 4, 5 & 6 again. If anyone solves this problem, let me know how.
Hope this helps someone!
