Macbook Wifi issue?

[DarkVictory]

I bought one of the aluminum Macbooks last month (the 1599 one). I guess now it's called a MacbookPro, I'm not sure.

I'm wondering if there is anything wrong with my Macbook. Once in a while it will not pick up my Wifi, even though my other devices can no problem. Is this normal? Is there something I can do to fix it?

I have the same problem occasionally with my mbp.

At first I thought it was my airport but the problem is still present with the at&t/uverse mandated 2wire. To top it off, I gave my airport to my sister who is reporting no issues with her macbook.
