Yeah, the Wii has a G card and uses a B driver, so it doesn't work on pure G networks; and forget WPA2. I bought the wired ethernet adaptor and ran a cable. Nintendo doesn't understand networking to save their lives. I don't get all the pissing and moaning about the 360's lack of built-in WiFi; Micro$oft didn't put in a major security hole for once and people are upset.
