Trouble getting airport to connect, HELP PLEASE!


I had airport working fine until i tried to install a graphite base station, after that i can not connect to any network. I have a hotspot also available and i can not connect to that either. I finally got the ethernet to connect but i have to turn off airport for that to even work. I am running an ibook G3 with an original airport card. The network light it is green and says it is connected to the internet via airport but when i ping something i get 100% loss on all packets. I have messed with this for over 20 hours now and i am at the breaking point.
