If you have a connect to your access point, then time to ping the AP and be sure 
packets are going. Then look at your routing with
   netstat -rn
and see if the default route is through the AP. Note that you still might have a 
problem with the connect between the AP and the net, if the AP isn't configured 
correctly.

Should see something like this:
   Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
   192.168.41.0    0.0.0.0         255.255.255.0   U         0 0          0 eth0
   0.0.0.0         192.168.41.100  0.0.0.0         UG        0 0          0 eth0

One step at a time...
