Thanks - I'll get a decent surge lead & give it a go. Should probably have one anyway.

The two adapters are on different rings (one upstairs one down) & worked fine in one bedroom, when we moved the PC the other bedroom it stopped working properly.

I have just had a look at the socket in the room where it worked fine & that socket is on a ring circuit, whereas in the new room the socket is a spur.

Do you think that being on a spur might cause problems?

This will have less of an effect the further the PC filters are away from the source (HomePlug) due to inductance in the mains cabling. The reactance increases with distance and you ideally need a large amount of reactance between both devices.
