You can try a Winsock reset. This will typically reset all network settings to their defaults and known connections to see if that helps. Make sure you know your network name and wireless password before performing these steps. To perform this reset, in the search bar of the computer, type in CMD, right click on the Command Prompt result, and select Run as Administrator. In the window that appears, type in netsh winsock reset and then press Enter. Once a verification message appears, restart the computer to complete this reset, and then attempt to reconnect to your network.
