Linksys WRT54GS Wireless Bridge
Yesterday I had the idea of using my Linksys WRT54GS wireless access point as a bridge to a neighboring wireless network. I knew that that capability didn't exist in the WRT54GS out of the box, but that there are various projects on the Internet touting aftermarket firmware capable of such a task. The most popular being Satori, from Sveasoft. I was able to download the firmware from LinksysInfo.com and install in a matter of minutes.
1) Unzip the Satori distribution to obtain the .bin firmware image
2) Login to the access point through the Linksys web interface
3) Choose to upgrade the firmware with the Satori firmware image
4) Once the image is installed, reset the Linksys access point by holding the 'reset' button for 15-20 seconds
5) Login to the access point to confirm successful installation of the new firmware
6) If currently running in 'AP' (Access Point) wireless mode, change it to 'client' to act as a client to the primary network. Specify the SSID of the primary network in the SSID text box.
7) Disable the DHCP server and assign a static IP (192.168.1.10, something currently not used) to the router.
Now, the router should be capable of bridging the ethernet switch to the neighboring wireless network.
