I just bought the Linksys Wireless Access Point Router with 4-port Eithernet Hub (WEFW11S4) and it works fantastic with my iBook and Airport card. I get a VERY strong signal throughout my 2 story house. I also bought its companion Linksys Wireless USB Adapter (W11USB) to hook up to a PC and I'm happy to report that works like a charm too. I get a 100% connection downstairs, about 150 from the router, which is upstairs.

Good luck.
