Try going to Control panel, Network & Sharing Center and setting up a new connection. You will need to know your network name and pass phrase (key). The pass phrase will be the same as whatever you use for other devices on your network. Sometimes is it given on the base or back of the router. If you manage this then restart the computer when finished.
Always pop back and let us know the outcome - thanks
