I recently purchased a mac book pro a few days ago and when i tried to connect it to my wireless network, it worked...but the internet connection is not working... it's so strange. the pages aren't loading, and i wonder what i've done wrong (forgive me, but i'm not too computer-savvy). when i go to the network diagnostics, the last three are red (failed).. isp, server, etc.. so i'm not sure what to do. i've been trying to figure this out for days!
