I have three Mac's one iMac, one Mac Mini (2010) and a brand new 13" MacBook Pro. I am using a Buffalo WHR-HP-GN wireless N router. All the computers except the MacBook Pro connect at N speeds, but the MacBook Pro connects at G speeds. All the computers are in the same room so distance is not the problem. I thought interference was the problem, so I turned off WiFi on the other computers and used Ethernet cables. Still the MacBook Pro would not connect at N speeds. I brought it to the Apple store and it connects at N speeds there. Any ideas why it will not connect here at home?
