QUESTION I have a pair of Homeplug 200 megabits per second (Mbps) Powerline adaptors, broadband web access and a Speedtouch ST585 v6 router. The PC is located upstairs and connected to the router via a wireless access point. I've connected a Homeplug to the router. I installed the software to connect one device to the Speedtouch, but the computer doesn't detect the Homeplug. According to the instructions, it should be simple and straightforward. I have no idea where to go from here – can you help? Jimskopi

HELPROOM ANSWER You may be experiencing problems with the electrical circuit in your house. Homeplugs require all the sockets you wish to connect through to be on the same electrical circuit.

If your upstairs electrics are on a different circuit from those downstairs, your computer won't be able to see your Homeplug. If possible, take your computer downstairs and run the connection software to see whether the Homeplug is visible to it. If so, you will need to rethink your setup.
