Clean Install and no wireless capability

I just did a clean install of Mac OS X 10.3 on my powerbook G4 and I cannot get my wireless airport to open any web pages with safari. I do not even know if I am explaining it right. I did a clean install because safari help told me that one of my updates may have been corrupted and to reinstall my operating system. I did the clean install because prior to, I was having the same problem with being unable to access any webpages on the internet.

Please Help!!

Did you update your install to the latest version of Panther? Another idea is to go further and upgrade to Tiger as life is better at 10.4.11. Wireless is a tricky thing to get right and the later you OS the better your shot. Have you tried hardwiring to the router to make sure that it can connect? It is possible that the wireless has gone AWOL.
