airport problem

[topper <mbdu@free.fr>]

Hi

I ve got an apple powerbook G4 with an apple airport (not extreme) inside.
I've got all modules compiled and loaded (hermes, orinoco and airport)
The card seems to be properly configured, and i even receive dhcp 
informations from my wireless router ---> iv got an ip and the router 
sees me.
But unfortunately, i can not have access to internet, i can not even 
ping the router.
This is not a problem of firewall (on my computer) and i have the 
default route to my router for my card (eth1) as given by the router

I don t see what s wrong....

Can someone help me?

Thanks
