"Network Cable Unplugged"... strange circumstances

In my house we have a cable modem that feeds to two computers through a linksys router. It uses Netgear Phonline adapters to get to each computer. One computer is running windows ME, and there is no problem there. However, on the other computer with Windows XP, there is some crazy stuff going on. Every day after about 5 or 6 p.m. it starts happening. The "Network Cable Unplugged" message appears randomly and with it the network and internet access goes out. It can happen in 5 seconds - 1minute intervals. Again, it only happens on the one computer, and only at night. Any ideas?
thanks

First thing is to ck your scheduled tasks for anything that might be running at that time..  Antivirus, etc...   then look around the house for something that is turned on at that time, that could possibly cause interference in the signal...  for instance, say for some reason you turn on a flourescent light at 5 PM..  It could be that the wire is to close to the EMI of the light..  Just a thought..

thanks, but I've tried that, I've stopped all the non-windows tasks, and I don't think there is anything that happens that time of day but I will make sure.  thanks for the ideas

You might try changing the time on your computer for a day or so..  Just to see if it is related to your system time...  Just a thought..

that's a good idea, but when the time change happened a couple nights ago, the problem didnt change with it, it moved back an hour on the clock, so it can't have anything to do with clock time

Left click on 'My Computer' and right click on Manage and look at the logs and see if something is kicking off.

I have a slightly similar problem with a computer that is running a Java to communicate between two applications on an XP machine.  It seemed to me that (about) when Windows Update - or Norton AV Live Update ran, I sometimes lost the connection and had to re-boot.  I changed the updates to manual and the problem seems to have gone away.

you know, i fell kind of stupid now.  I switched the ports of my modem and my network card and now the problem has disappeared.  this still doesnt explain the crcumstances, but it seems to work (it has for a few days).  sorry for not trying that earlier.

You know I had an issue years ago with a computer that would dial up at night to a database and download info......except every night it would drop the call....works fine during the day, so finally I came into to see what was happening during its scheduled download time..........youll never guess.......

The cleaning lady was using the circuit the comp was on.......yup you guess it.....

Sometimes it has nothing to do with the computer itself.

if you missed it, the solution was switching the port that the card was in.
