Hello, i have a white mid 2007 macbook with Lion. I recently sold it to my friend who is trying to connect to his router via wifi. He has a 4S and iPad 2 which connect perfectly fine. the macbook shows that its connected and diagnostics say he is connected fine as well. Unfortunately he cannot load pages without it taking a couple minutes (google or yahoo). He has renewed his DHCP lease as well as reset router/modem. Any info at all is appreciated, tia!
