I'm curious if the hardware in a WRT54GL would support this. Especially if it could route the connection to one of the ethernet ports so that there would be minimal configuration on the desktop end. In case it isn't clear I'll try a more visual representation: Internet -> Modem -> Wired ethernet connection to the WRT54GL would be internet connection #1. Obviously that would be the primary and you could plug several ethernet cables in to use it. I'm wondering if you could then use the unused wifi on the WRT54GL to bridge connections to another wifi router which would of course have its own internet connection, then tunnel that second internet connection to one of the ethernet ports on the WRT54GL. Is there anything about the hardware in the WRT54GL or other routers that would prevent that from working? Could it work? Provided of course a firmware could support it.
