Default Network wiring problem - weird one!

wrote in message
...
When we had our extension built recently, I took the opportunity to
install a Cat5 LAN. Well, to be more accurate, the electrician ran
the cabling in but said he didn't do network wiring so the tails sat
there for a while until eldest son got his new laptop. I got a friend
who is an experienced network engineer with his crimping tool to
install the face plates for the network points.

The engineer had a wee gizmo that he plugged into the individual
points and then another into the 4-gang which lit up to show that the
wires were correctly connected. Everything seemed fine and dandy and,
as I say, he's an experienced engineer.

Unfortunately the network doesn't work. A laptop plugged into any of
the individual 1-gang outlets can't see the network. However, if it's
plugged directly into the back of the router, all is fine.

Anyone any thoughts? I bought the cable from work (we do network
installations, though I'm a software engineer myself) - it's
unshielded twisted pair, and it's what we have in our work LAN.

Thanks


One obvious answer is that you have patch leads with cross-overs in them.
Assuming you haven't checked this, get two leads that work connecting the
laptop into the router and use one of these as a patch lead. If you have
already tried this or it still fails, maybe there's a crossover in the
installed cables - try a patch lead with a crossover! Otherwise, in spite of
his test, the cabling isn't correct.
