I had the same problem and it was a MTU problem as Guillaume says.
In your /etc/network/interfaces file, add these lines where you 
configure your wireless connection :
       mtu 1450
       up echo "0" > /proc/sys/net/ipv4/tcp_window_scaling
       up echo "0" > /proc/sys/net/ipv4/tcp_ecn

Then restart network with :
/etc/init.d/networking restart

And try again to use internet, it works for me.

Hope this helps
