Do you have a wireless USB or wireless card attached to the router, or do you all just hook it up to it.
If so I had about 5 weeks of fun with it before it worked properly.
I suggest screwing around with the router itself. Type in 192.168.1.1 in your internet browser, then type in admin for password. (no username)
Check if you accidently set a static IP. Also ensure you dont have any MAC address set. I prefer setting the channel on 11 also, check out your computers set IP addresses.
Otherwhise there is always tech support.
