Need to turn off Proctected WiFi on the router as it's not needed for PCs, mainly for wireless devices like printers and such. Setup security and a password under Setup/Wireless settings/manual. Set up a WPA or WPA2 security mode. Down under Cipher type should be a selection for Auto TPIK or AES. Under that you should see a box that you can enter in a password that you want to use, can be anything, make it something you remember. Once it's set up and saved in the router. Go to your wireless device and connect to the wireless SSID you made. It should ask you for a password, enter this in. It should connect.
