I had posted on here before of I problem I am having with my AirPort card. Some people suggested that I am just receiving interferance, but I now know that is not the case. For whatever reason, my connection randomly goes away. The icon turns grey like it is not receiving a signal at all. I know there must be some problem internally, because I live in an apartment, and at any given time, I can see at least 4 other networks within range of my PowerBook. In order for Airport to work again, I have to completely shut down my computer and start it up again. Sleeping, restarting, or logging out does not fix the problem. Any ideas of what is going on would be greatly appreciated. Thanks in advance! BTW...I am using a PowerBook G4 (titanium) with OS X 10.3.2
