I have an interesting situation. I have my cable modem and Netgear wireless router in my basement. I have my Xbox 360 and desktop PC on the second floor and neither has a wireless card.
What I do have is an extra Linksys WRT54GL wireless router. I'm wondering if it's possible to use that as a wireless repeater/port replicator so I can hook it up on the second floor, have it connect to my main wireless, repeat that signal, and also have the 4 LAN ports work as part of the "repeating". This would allow me to use the Xbox 360 and desktop PC via wired connection on the Linksys router upstairs (and not pay money to buy wireless adapters).
I haven't flashed the DD-WRT firmware yet, but can do so if needed.
Thoughts on this? Is it possible?
