It depends where it is being stopped.
If you are using windows then try pinging to web sites and the router.
start>run>cmd
in DOS box type ipconfig and press enter.
The info should show a wireless connection with a 192 ip
the default gateway is the router, probably 192.168.2.1 or suchaslike.
type : ping {correct ip of default gateway} and press enter.
