396157 2005-10-14 06:01:00 I have a situation where there are network plugs wired into the walls of a new house .the sparky tells me that there should be a 'straight thru' connection between two particular rooms.......so ....one plug in one room joined by ordinary network cable to the other plug in an other room......k so I had a laptop and pc to network I set the lappy up beside the pc and networked them using a crossover cable this worked well. Then plugged an ordinary, (not crossover) calbe between the pc and the wall plug and took the lappy to the other room where I plugged it into the wall socket with a crossover cable...........no network. tried pluggin em both in with 'straight thru' cable in case the sparky had somehow wired the wall plugs as crossover . no network. didn't matter which pc I had plugged in with which cable I couldt'n get a network . Am I right in thinkin the sparky most likely didn't correctly wire the network ? apparently the cable from teh two plugs are joined behind a socket thing in the pantry cupboard. perhaps they didn't join em ?

I woulda have thought that with one end crossover and the other end 'straight thru' cable it shoulda worked ? or should i have had a crossover cable at either end considering the 'joiner' cable *should* be wired correctly and be 'ordinary' patch cable ?

396159 2005-10-14 06:37:00 Two crossovers would cancel out, so if using a crossover cable, a straight through connection would be needed between sockets. If he has crosssed them over, a straight through would be needed to reverse that effect.

There is no guarantee that there is even a connection between outlets anyway. If there are more than two outlets then a central outlet hub is needed to connect to a switch or a hub. I installed a six-way outlet plate under my desk with individual cables up to my switch. This services my office and five more outlets around my home.

I'd take a closer look at the "socket thing" in the pantry. You may find a connector strip paralleling all the conductors, or not, as the case may be.

396160 2005-10-14 07:02:00 well i tried

LAPTOP:crossover > sparkys cable > straight thru:PC

LAPTOP:straight thru cable> sparkys cable > crossover:PC

LAPTOP:straight thru cable > sparkys cable > straight thru:PC


THE only one i didn't try was

LAPTOP:crossover > sparkys cable > crossover:PC

and now i'm wondering if that woulda worked ......grrrrr......

rang the sparky and they're gonna go check their connections but I dont wanna look silly..... :-(

396161 2005-10-14 07:26:00 Probably just not connected. You could try a modern network switch as a test (it will be able to automatically corssover if needed). Plug in one socket using a normal cable and plug your laptop in the other socket.

As the other poster said you don't want to connect the wall sockets directly, the cables should run separately back to a space where you can install a network switch (after all maybe you want to connect more than 2 devices, say a desktop, a laptop and an external ADSL router..)

People have also been know to stick a nail through network cables :eek:

396162 2005-10-14 07:32:00 damn a switch woulda been useful to try for sure............if I had one...... drcspy (146)
396163 2005-10-14 07:33:00 People have also been know to stick a nail through network cables :eek:

... and copper pipes. The difference being you know about the nail thru the cable pretty much at the time, the pipe one will get you when you have been away on an extended vacation and return home to a pool party in your living room.

396164 2005-10-14 11:14:00 Take the sockets out of the wall to see if the wires match up, you can check the colors here (www.incentre.net) Rob99 (151)
396165 2005-10-15 00:39:00 interesting thanks.........but I"m not going to open up those things the sparky can do that I've no idea what they've done drcspy (146)
396166 2005-10-15 00:57:00 Totally the electricians problem.
If xover or patch doesn't work, when it works directly...there is a problem between outlets. Either a hole in the middle (not patched or jumpered) or one/both of the sockets are wired incorrectly.
