sid Posted March 13, 2011 Share Posted March 13, 2011 I've been using a Netgear Powerline adapter setup for over 2 years without problems. My "main" laptop and router in a small office and another laptop in the dining room. Yesterday I moved my "other" laptop to another mains socket on the other side of the room and it no longer connects to the network. No extension leads, no surge protector connected. This mains socket is on the same circuit as the one I moved it from. Any ideas as to what the problem could be? I've read that they don't always work but what technical explanation could there be? Sound like a house wiring issue... but what?As a further test I spent another hour going round all the sockets in the house and then out into the garage and barn; it works everywhere else, even 40 metres away at the far end of the barn. Very odd. Link to comment Share on other sites More sharing options...
Rjpfrancais Posted March 13, 2011 Share Posted March 13, 2011 This is just a thought off the top of my head and I am not sure if would make any difference but could it be that the live and neutral are reversed in the socket giving you the trouble?

sid Posted March 13, 2011 Author Share Posted March 13, 2011 Hmm! Possible I suppose. Worth a shot. I'll dig out my mains/earth tester thingy and report back. Link to comment Share on other sites More sharing options...
sid Posted March 14, 2011 Author Share Posted March 14, 2011 No, polarity OK and earth OK. The CPLs are 2-pin devices so it is possible to insert them "upside-down" anyway, so I guess that polarity is not important. I've read on the web that sometimes the odd sockets does not work but there's no explanation! Link to comment Share on other sites More sharing options...
tonyv Posted March 14, 2011 Share Posted March 14, 2011 My guess would be that this is due to transmission line effects. Basically, a standing wave is set up along the power line, resulting in a "null" at that particular socket. Think of your FM car radio, which wont't receive a particular programme at one position, which is perfectly clear a few meters further on. Link to comment Share on other sites More sharing options...
Quillan Posted March 14, 2011 Share Posted March 14, 2011 This is probably a silly idea but I wondered if your house has a single phase or three phase supply and that if by some fluke this one socket may have been 'added on' and is on a different phase?

tonyv Posted March 14, 2011 Share Posted March 14, 2011 Hmm, Q, did you miss the OP's "This mains socket is on the same circuit as the one I moved it from" ? Link to comment Share on other sites More sharing options...
sid Posted March 14, 2011 Author Share Posted March 14, 2011 Quillan, the house is single phase and this socket is on the same circuit as 2 others in the same room, both of which work OK for the network.It's really puzzling, and a bit annoying as we'd prefer the PC to be set up in the corner of the room where this rogue socket is.EDIT Sorry Tonyv, I repeated that detail while you were posting your reply.

Quillan Posted March 14, 2011 Share Posted March 14, 2011 Oh dear, sorry about that. Can I suggest an alternative. If the computer has a WiFi card (if it doesn't you could by a USB 'dongle') you could the use the same sort of thing to send the signal round but there is a WiFi extender version. That bit could go in the working plug and should 'reach' the computer on the other side of the room with ease. I was thinking somethin like this - http://www.amazon.co.uk/WiFi-Ethernet-Home-plug-adapter/dp/B002QAEF76/ref=pd_cp_ce_0 Link to comment Share on other sites More sharing options...
sid Posted March 14, 2011 Author Share Posted March 14, 2011 That's an interesting alternative which I hadn't seen. I'll have a think about it, thanks. Link to comment Share on other sites More sharing options...
