Problems with computer cable extension.
hillbillyracer - 16/3/08 at 08:00 PM

Our computer is sited in a spare room upstairs & the phone line comes into the kitchen at the other end of the house downstairs. We were having connection problems with the cable which is just an ordinary telephone extension run though the inside of the house, when a new cable was connected the problem went away so we expect the cable has been damaged at a door.
As a better solution we have run the cable back out the kitchen window externally & then under the floor upstairs using what I'm told is data cable that a freind had left over from connecting computers in neighbouring houses. We dont have a plug & socket to fit the data cable so I've just soldered the ends of the old extension line to it to get us going till we get it sorted properly.
The problem is that it wont work with this setup, if I connect the new telephone extension lead up instead then it's fine (if it didnt you would'nt be reading this! .
So what will be causing the fault?
The new cable has 4 pairs of wires, each pair twisted together, when I soldered it to the old lead ends I joined each pair as one wire could it be the cable is too thick now?
The new cable just for ease got clipped to the telephone cable coming into the house along the outside wall, would this have an effect like running it next to electrical cables would?
Another factor is that we are about 3 miles from the exchange which can't help.
We've looked into going wireless but the opinion of "experts" was that the big thick walls in our old farm house would cause too many obstructions.
Thanks for any help, Kev.

Google is your friend!
But if you are too lazy click here

The data cable (ethernet) should be good for 100m if you have your modem with an ethernet port plugged into the phone line and the other end of the data cable into the ethernet socket on your computer.

Sounds like you will need new plugs on it though

Cheers

The thing I'm trying to understand though is why one the cheapo extension line works but the good cable doesent, I've checked that I've connected everthing the right way round. The only thing I can think of is my having soldered the pairs of wires together as one wire making it far thicker than it needs to be, I only connected them that way because they were there!
Distance should'nt be an issue, both cables are about 20m, & the previous cable through the house was 30m by the time we'd run it round the edges of walls etc.
Thanks for the link nitram38, it's shown me that I've got stuff connected right & that we have the crap old style BT master socket without the removeable bottom half
Mabye we'll just have to run with the telephone extension laid through the house till we get the right plugs sorted.

differing signals have different requirements on the wires.

Assuming this is all so you can use a dialup modem, I would suggest you simply get a decent telephone extension kit from maplin.

Sorry, I never thought to say, we have broadband way up in the wilds of Cumbria!

You might as well have told me to use sky hooks & moon beams! (I've a long way to go before I become a computer expert). I'll have a look about on tinternet to find out what you're on about.
The idea was to just wire it like the telphone extension we had but run outside to avoid running it around doors etc but if there's a better system without going to great expense then it's worth a look.

I've had a look to find out what power line networking is & found this:
http://computer.howstuffworks.com/power-network1.htm
I like the idea but we've already run this other cable in & it says on there that it's only suitable for the 110v systems in use in the USA but I'm guessing as you lot suggested it there are systems that work in the UK.
My boss is away to a computer fair tonight & is trying to connect the computer in the workshop to the one in the house & is having similar problems so he's going to see what he can find out.

If you want cheap powerline networking then order BT Vision for 30 quid from here and choose self install, pay per view. BT will send you a pair of comtrend adapters along with the set top box. You can then take a torx driver to the box and remove the 160gig HD for your own use elsewhere and bin the box. Quids in.

All useful, but if you aren't on BT broadband and can't take advantage of the BT vision thing then get on ebay. The Comtrend 200Mbps kits sell for 30/pair on there.

As it happens we have BT broadband so that's all useful stuff, thanks.
My boss has got some of the correct connectors for the cable we have so we're going to give that a go first & if it's not right then this powerline networking may well be the way to go, cheers.
