I've got a WRT54GS v4 with Official Firmware 1.05.2 as my main base station. I also have an AirPort Express that I want to put in the living room and use it to connect my Elgato EyeHome to wirelessly stream video from the PC to the TV. I'm new at all this and I think I need to set up a WDS with the WRT54GS and the AirPort Express. Is this possible to do using the official firmware? If so, what are the steps?
