a network cable is unplugged

I just booted up two of my computers and both of them are giving me this
over and over. It's been happening for some time, but not this bad! Bad
router you think?

And switches between:
Local Area Connection is now connected Speed 100.Mps and
Local Area Connection is now connected Speed 10.Mps

Try different cables, and check that:

a) They're straight not crossover (ie. the order of the wire colors at both ends
is the same)
b) You're not plugged into an uplink port (used for connecting switches, etc to
one another)

First try to check to see if the router is functioning properly. It may have
failed, or require to be reset. This can be a task, if all the entries have
to be redone. I have had routers having to be reset, or fail.

It is rare that Ethernet cables will go defective, unless they are in an
area where they can be disturbed, or users are un-plugging and re-plugging
them all the time, or people are able to walk on the cables.

Check the cables, their plugs, the socket, etc. Rarely I
find systems that have rear case slots off-spec a little
such that the RJ45 connector's locking tab doesn't seat
fully due to being depressed a little by the slot
cross-member. In such a case an adjustment of the NIC,
motherboard on the standoffs, or a different NIC might help.

Check the switch Link and 10/100 connection LEDs. Do they
change? Do they change if you wiggle the cable slowly?

Check for dirty contacts, if you had a spare switch it
wouldnt' hurt to try it. Some of the passive switches have
capacitors that get really hot and might not last very
long... how long can only be seen in retruspect, IF/when
someone has theirs fail.

You haven't menitoned what you HAVE done so far to try and
troubleshoot this though, it would be good to know so we
don't redundantly cover basics that you've already tried.

Some NICs have software that can give you cable
length/signal-strength/etc feedback. 3Com, Intel (can't
remember) and some Via chipset NICs come to mind as those
that do... and probably others.
