You say you can ping fine but... browsing doesn't work?? Maybe a firewall issue? /etc/init.d/iptables stop I agree with Pavel this does not seem like a driver issue.

Can you try a simple netcat server and netcat client on different ports and also on port 80 just to see if its really firewall/AP configuration. Luis
