I moved my computer, running Windows 10, from the room with the router, to another on a TPLink adapted. I couldn't get wifi, so up against a time deadline I connected by Ethernet to the TPLink system. Later in the day this also failed to connect to the Internet. I have moved the computer back to it's original location, and still cannot get either wifi, or by Ethernet. Other devices, lap top and iPad connect to wifi in both locations fine. Presumably it is settings on the PC ? Help please. Thank you.
