Hi Kevan, Yep, I have been using a pair for about 18 months now. Devolo is the make I use. I have also installed this on about a dozen sites or so and one failed. The reason being that the pair (source and destination) were on different phases. On other site there was an electricity meter in between and we got that to work by putting the destination device before the meter and then used a longer Ethernet cable. It does work across breakers on the same phase. As far as I know it does not use the earth wire because I used it on an unearthed extension and it worked fine. But to be save and test first, if you can. There could also be interference from equipment on the same 13amp ring preventing it working. Hope this helps, Walt -----Original Message----- From: staffslug-bounces(a)staffslug.org.uk [mailto:staffslug-bounces@staffslug.org.uk] On Behalf Of Kevanf1 Sent: 27 January 2011 15:07 To: Staffslug Mailing List Subject: [Staffslug] Ethernet over power lines. Does anybody use the ethernet over power lines system at home? I think the brand was Devolo but there may be others? Anyway, it's the way of setting up a home network by pugging the ethernet cable into a special power socket plug, I'm sure you all know what I mean. I just wondered if there are any restrictions on usage. by that I mean does the network all have to be on the same breaker circuit (downstairs sockets or upstairs sockets) or does it use the earth wire? -- ============================================== Kevan Linux user #373362 Staffordshire ********************************************** www.freeworld-recycling.org 'From me to you towards a sustainable future.' ********************************************** _______________________________________________ Staffslug mailing list Staffslug(a)staffslug.org.uk http://lists.staffslug.org.uk/mailman/listinfo/staffslug

I put a couple of the netgear ones in for a friend and they have been working away fine now for 18 months. They are on different circuits up and down I think. I don't recall what sort of speed it was getting but it was better than the wireless connection he did have. I have to say I was (am) incredibly sceptical about them but they do seem to be doing the job. Probably not applicable to a business environment though. Just my 2p.

I remember a home automation system based around a Commodore 64 where the different components communicated over the mains. That would have been around 1986. Google tells me it was also available for the Spectrum. Here's a page about it: http://www.worldofspectrum.org/hardware/feat34.html

There are two approaches - apparently Maplin used to sell a pair of modules that would send/receive several channels (analogue and digital). Alternatively, it had a simple receiver and transmitter circuit that you could build yourself. IIRC, the DIY circuits would only transmit on/off commands, but they were much simpler and cheaper than the commercially-built modules.
