Is it possible to share an internet connection through WDS? I'm on the very edge of a wireless network, the spot that I'm in maintains a stable 22% according to XP with the help of a parabolic reflector crafted from a cheap pie tin. I was thinking I could grab another wireless router, use WDS to bridge the this router with the other one and share the 'net connection through it thus giving me a little bit more freedom but when I tried it it didn't work. WDS looks like it bridged the networks just fine, but I couldn't access anything on the internet. Do I need to do anything special or is this just not possible?
Yes this is possible. I have done this configuration with both the DD-WRT and Tomato firmwares on on a Linksys WRT54GL. In my particular configuration I had a WRT54G acting as the router connected to the internet and my WRT54GL was bridging the connection to a couple of devices that I had wired to the WRT54GL.
I am no longer using this configuration, but I did have it running for over a year so I know that it works. I don't know if any of the stock firmwares support it, so you may have to install a 3rd part firmware on the router in order to get this feature.
