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. Do you have
your AP configured to disable :80 TCP communication? 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.
