I had my house wired up with ethernet ports in each room (yes I am a
nerd:-). I keep getting a message on my PC saying "a network cable is
unplugged". The message stays for a few seconds and then disappears. Network
during this time is interupted but resume ok after the message goes away.
I've confirmed it's not the network card in my PC and it's not the switch.
Assuming it's the wiring in the wall, what would be causing that?

What NIC is in your PC?
I have the same problem with the Marvell gigabit port on my DFI
mainboard. The nVidia gigabit port on the mainboard works fine with the
same cabling. I expect a driver issue, but haven't really put a lot of
effort into fixing it.

It's a dlink GFE-530TX gigabit PCI card. The card isn't the problem (I
presume) as I had the same issue with my other card which was a Zyxel
gigabit card. I actually suspect now it's not the cabling in the wall as I
hooked up a cable direct to the router and I still got the same problem. I
suspect it might be the dlink router. Did I mention how much I hate Dlink
junk?

I've tried running the card into a 10/100 switch also and had the same
problem, althought I'm going to confirm that again (it might take a day to
confirm). I guess it's a matter of problem solving until I find the cause.

When you get the message is the computer always connected to the same wall
plate with the same cable? Swap cables and try again. Move the computer to
a different wall plate in a different room. Connect a different computer to
the original wall plate. Swap router/switch/hub ports around and see if the
problem moves.
Personally, I've installed Ethernet outlets all over my house too and wired
them to a patch panel in a closet in the basement with my DSL modem,
router, switch, and file server. The one problem I've had that seems
similar to yours was caused by my own clumsiness in preparing one wall
plate connection which caused a wire to break internally which caused
intermittent problems. Because the outlet was behind my home theater stand
finding the problem and fixing it took a long time and required nearly
standing on my head.

I'm in the process of doing all that. It's not easy as the problem sometimes
doesn't show for many hours. I think I've eliminated the cabling in the
wall. The problem is I think I've eliminated everything. It's not my PC, not
the patch lead to the wall, it's not the cabling in the wall or the patch
lead at the other end, it's not the switch and I think it's not the router.
I'll have to go back to see what I missed, I suspect it is the router which
is what I'm testing now.

It seems to be getting more common now, on new homes it's an optional extra
where you just tick the box and it gets installed.

sounds like some poor troubleshooting..
try different computers, different sockets.
Try DIRECT to your hub.
(presumably in this structured cabling you have, the sockets in the
wall "attach" to a hub in a room somewhere)
you should be able to isolate what it is, whether it is windows
corrupted somewhat on one computer.. Or a cable, or whatever.
If you really cannot isolate it, then just list all your
troubleshooting reasoning, and people can improve it.

I've gotta admit I didn't follow a well structured troubleshooting plan at
first. Generally though it's not necessary, just try a couple of things and
usually the solution presents itself. There was added difficulty in this
case because the problem would sometimes not show for hours and because of
this I thought a direct cable connection had solved the problem when it
hadn't. Usually when standard problem solving fails then there are multiple
problems. It turned out that my dlink network card was faulty and also my
dlinlk router. The dlink wireless box was also faulty but that wasn't part
of this problem. I've bought a linksys wireless router and plugged in a
non-dlink card so everything is working again. I guess it really was one
common point of failure - Dlink. That problem is solved for good.
