I have yet to find a real solution for my problem. I have a horrible wireless connection in my house, but it's fine everywhere else. I've used the internet in my local Apple Store, and at my school today - flawless. I come home, connect to our network (broadcast through an Airport Extreme Base Station) and I get maybe a few seconds and then nothing (I monitor this via a ping). For whatever reason (I can't really explain it because in both cases it was like dumb luck), I've been able to maintain a stable connection twice. I don't really know what I did - I tried many things, mostly using Network Diagnostics with Ethernet plugged in, then unplugged running the diagnostic, combinations like that. In both cases, when I turned my computer off and then back on, the problems came back. It has to be something with my network, but I don't know what it could be because my previous generation 15" MBP and 24" iMac are connected fine - it's just my new 15" MBP. Any idea or possible solutions? I'll probably bring my computer in on Friday and have them look at it over the weekend.
