Try reseting the router to factory defaults. Using a paper clip, press the reset button at the back of the router for 10 sec and let it go. After the routes initializes, type IPconfig /release and then ipconfig /renew on the command prompt from one of the computers directly connected to the router. If you do not receive an IP address from the router, I will suggest that you contact technical support at 1-877-453-5465 for further assistance.
