I live in a fairly new house, 2002, in a small estate. The master socket
for the phone is just inside the front door. There are also extension
sockets in the lounge and upstairs in the master bedroom and one of the
smaller bedrooms. That last was an extra I arranged while the house was
being built. Others on the estate seem to have a master socket by the
front door, one in the lounge and one in the master bedroom. My brother
lived at one time in a new house off North Road where the old school
once stood. He also had the master socket by the front door plus two
extensions.

Why all this going on about the master socket? Well, since I have lived
here I have always had my desktop computer in the smaller bedroom and
used the extension socket. This has worked really well. Now I find that,
for FTTC, I *must* use the master socket, which is in the entrance hall.

I did have a thought about this just now, maybe not a neat solution unless you've got maybe a small cupboard that the modem can be put in, but one possible way of powering it would be to use a POE injector and POE splitter with a length of Ethernet cable.

Basically put the POE injector next to your router, presumably next to your PC and plug it into the mains. Plug the non-injected end of the Ethernet cable into the router, then the injected end (power and data) connects to the long cable to go to the modem.

At the modem end plug in the POE splitter. This has two outputs, Ethernet and power (the TP-Link POE splitters we use can provide 12 volts at 1 amp, 9 volts at 1 amp and 5 volts at 2 amps). The Ethernet and power connections plug into the modem and it gets power over the Ethernet cable.

While it's not the neatest solution it could work (well assuming the modem doesn't draw any obscure voltages or amperages).

I've done this at work with a switch to extend a leg of network which was over 100 metres, basically after about 50 metres or so we put in a POE splitter attached to a standard 10/100 8-port switch, from there it goes into another long length of Ethernet in a shed.

The TP Link injectors and splitters we use are:
