All of my network cables are currently set up for a cable modem and router in my work room, but that isn't where the phone line comes in - that's in the hall about 25 ft away. There isn't a mains socket there, though there's one just the other side of the wall so that isn't an insurmountable problem.
Am I right to think that I'll have to put the ADSL modem near the phone socket, rather than using the extension phone cable I already have to get it in here?
Not a huge problem either way, if I put the router in the hall I can run a network cable into this room and use a switch in here - might even improve wireless reception around the flat. It just affects what cables etc. I'll need to get.
