Ibook Airport Mysteriously Stopped Working


I have a G3 iBook 800 Mhz w/ 10.2.8 OS X. All of the sudden my airport wireless decides to stop working!

I can see the networks and their signal strength, but I cannot surf the internet or retrieve an IP address. Only when I connect my iBook into my hub I can surf the internet. On my other laptop w/ wifi I can connect no problems.

I really don't know what to do to correct this problem. I tried messing w/ the router and making changes to my iBook. I never updated or touched the wifi router (linksys) that is used to work from, so I did kind of rule that out.

Any suggestions or ideas would be great! Thanks ahead of time for the help!
