I recently bought a new Linksys E2000 Wireless Router (N Band) since my old Linksys WRT54GS (G Band) did not have the range to reach my basement where my Wii is set up. After setting up the new router, I realized that the Wii does not work with Wireless N. When I set my new router to use Wireless G, It also did not have the range to reach my basement.
Frustrerated, I thought there must be a way to connect my old router to my new router to get a wireless signal into my basement. After searching the web, I found a solution. Using a third party firmware (www.dd-wrt.com), I was able to connect my two routers using the old WRT54GS as a Wireless Gateway Repeater. Set up was pretty simple (Followed the simply steps listed here (www.dd-wrt.com/wiki/index.php/Repeater_Bridge) and I was able to get a wirelss signal to my basement.
I feel great as I was able to identify a problem, think things out, and then take the steps necessary to resolve it without spending extra money (my old router wasnt being used; was going to give it away) and without a lot of time (took a few hours to get everything up and running)
