I suppose you use the network manager applet which Ubuntu uses by 
default. Some people have more luck using wicd instead of network 
manager. If you install wicd, please remove the network manager packages 
because they may be in conflict if both try to use the wireless 
interface. But before you try wicd, what is the output of these 
commands?

route -n
cat /etc/resolv.conf

That should at least clarify if you got the needed network configuration 
via DHCP. The route -n command should give you the IP address of the 
access point. You should be able to ping that address. If that works, 
you can test the name resolution with

ping www.google.com

Another option would be to reset the access point (disconnect the power) 
but I'm not so sure it would help.

As you can connect to other access points, it is unlikely that the 
driver is the problem.
