My MacBook, circa 2007, refuses to connect to my home WiFi network, despite having added my MAC address, being WPA encrypted, updated firmware and the like. I haven't had a problem in the last year, until I started taking my laptop to work. It connects to my work wifi network, WPA encryption, and every other network. I have no idea why it wont connect at home. I'm running snow leopard, other macs and PCs at home can connect... It seems I'm missing some odd quirk, I've seen a few threads of similar complaints, but no working resolution. Any ideas? I've wiped out Safari, cleaned all network settings, and it all started once my use shifted predominantly from home to work. Hmpf.
