Rj45 to RJ11

[NotAllThere]

I'm still playing with the using the phone line, 'cos I'm awkward like that.

Now, I've got RJ11 to RJ45 adaptors. They link the middle four connectors the RJ11 to the middle four connectors of the RJ45. So where the RJ45 goes brown-white-green-white-blue-green/white-orange-white, only green-white-blue-green/white are connected. blue-brown-white-yellow

In order:

RJ45 green - RJ11 blue
Rj45 white - RJ11 brown
RJ45 blue - RJ11 white
RJ45 green/white - RJ11 yellow

Seem ok?

I think you've got the wrong wires for ethernet. Your adapters are probably for phones:

Why not just use a couple of Homeplugs? I've got a couple and they're great.

I've rewired the adaptors now, so that I'm using 1,2,3 and 6 on the ethernet end. Still no connection; maybe the wiring behind the socket is dodgy - I'll check that.

Does powerline work when you've got european wiring - circuit board with two switches, and 5 circuits off each? Even so, I've got all the equipment for doing it the ethernet, so it would be nice if I could get it working!

I don't really understand why don't you just google it all
I occasionally used to split the Ethernet cable and used the unused pair to wire the phone, but not the other way around.
The reason being, electrical signalling scheme in Ethernet (codenamed Manchester I believe) uses higher frequencies (36MHz for 10Mbit and 360 for 100 - again from a distant memory), which is still much higher than Plain Old Telephony System, being a simple analog representation of our voice and cutoff at around 10KHz.
The reason there are 4 pairs of wires in Unshielded Twisted Pair cable, is to shield and reduce interference, they're also twisted in a very specific fashion.
Like I mentioned not all wires are used, but that's also for a reason.

The only things I can think of than can work over a simple copper cable used for telephony are:
modem (up to 56kbit)
serial (up to few megabits depending on the quality of the cable)
adsl

but why bother? I'd simply go and route a nice, cheap cat6 (or cat5e) and run a gigabit network over that. If you don't have means to route within the house, just run it through the windows or sth.
