Just ran Software Update, now wireless (Airport) doesn't work...

Hello,

I just ran Software Update on my Macbook and after doing so, my wireless internet stopped working. It still shows full strength for my network, but no browser or other program will connect. This is the second time this has happened, the first was fixed by a re-installation of Leopard, but the same updates made it stop working again.

To me, the two updates that seem most likely to have caused this would either be the Airport Utility update, or the Mac OSX 10.5.2 Combo update.

Do anybody know what is going on and how it fix?

Thanks!

I have restarted both the modem and the router. Unfortunately, neither worked.

The Macbook reads that my network has full strength, and I know that is true because the other laptop in the house works fine.

All of ones that were available until they made my internet stop working.

I tried connecting ethernet to my Macbook, but I still couldn't connect to the internet.
