If you run the USRobotics Network Test, follow the instructions in the utility, and still cannot connect to the Internet, manually step through the remaining procedures below.
If you can connect to the router's configuration pages: The problem is not in the connection between the wireless adapter and the router. Go to "Verify the Router's Connection to the Cable or DSL Modem".
Reset the router. If the router has a Reset button, follow the instructions of the router manufacturer for using the button to reset the router; otherwise, reboot the router by disconnecting and then reconnecting its power supply.
Note: When you restore the factory defaults, all your current settings of the router will be lost and you will have to repeat the installation of the router.
Note: If your ISP uses a static WAN protocol, make sure that the WAN IP address of the router is the one that is provided by your ISP or is in the same subnet as the device that is connected to the WAN port of the router.
If you still cannot access the Internet: The problem is in the cable or DSL modem or your ISP. Contact the customer support department of your ISP to determine whether there is a problem with the modem or Internet connection.
