Can't make wireless conection to internet

[James W Eanes Jr.]

I have a HP ZV5255USlaptop running Windows XP Pro and Fedora Core 3 
X86-64. I can connect and use the internet with windows  but not under 
Fedora. I used NdisWrapper to get the broadcom chip to work. I can get a 
conection to the network. When I try to ping anything on the internet 
DNS will resolve the address but then I get 100% packet loss. Using 
wavemon it shows alot of activity but I get nothing. I have tried 
disabling the firewall but no change. I don't understand what's stopping 
the conection.
