Operating system WINDOWS XP with two network cards, one is disabled, the other is hardwired to a linksys wireless router. I RECENTLY had to rearrange my office and needed a longer cable to connect my computer to the router. When I plugged in the new cable to the NIC card and router I get the network cable unplugged. Check the connection and they are fine, plugged network cable into another computer on the network and that was fine. Is it possible that the other NIC card is interfering with the other NIC card Ran a check in device manager and both NIC cards when enabled are WORKING fine. So any suggestion would help.Why do you have two NIC cards installed? If it worked before I doubt that's a problem, but it would be simple enough to make sure. Just pull out the disabled card.

Just eliminate potential problems one at a time.I thought the first one went bad at the connections because I got the same message that a cable was unplugged. so when I installed the new NIC it worked fine. And it has worked fine until I had to replace the cable to a longer one then I get the message Cable unplugged.1. I'm with "rthompson80819". Remove the extra network card. Probably won't solve the problem, but it simplifies your configuration.

If you open up the machine (use a grounding wrist strap - see ElectroStatic Discharge or ESD), do it this way:
a. Shutdown, power off, and unplug power cord from computer (to ensure no standby voltage to motherboard). Actually the ESD link recommends you remove all cords from the back of the computer. At least turn the monitor power off.
b. Remove both network cards.
c. Connect power and reboot all the way into the operating system (this should remove both cards from your software configuration).
d. Shutdown, power off, unplug power cord.
e. Insert one network card.
f. Connect power and reboot. System will rediscover card and assign driver from its database.

Maybe you'll get LUCKY...

2. What version and service pack level of Windows XP?

To check: Start -> right-click My_Computer -> Properties -> General tab.

3. Can you provide the "exact" message string for "Cable unplugged" and where and when it appears. Perhaps someone with time on their hands can survey the Internet for cause/solution...

4. What's the product name/number for the network card you want to use? Usually they have "status" LEDs on the back that show whether they have physical connectivity and activity. What do your status LEDs SAY?

5. Linksys Router.
a. What is the model number of Linksys router? Sound be on the bottom...
b. What is LAN status (LED) for port Windows XP computer connects to?
