 I began to experience a problem with my Internet connection. On one of my PCs, in the notification area, an icon consisting of two monitors with a red "X" appeared with the message: "Local Area Connection: A network cable is unplugged." However, the cable is not unplugged

First, I thought it may be the cable, so I replaced it with another cable I had. No luck.

Then I thought it may be the port on the switch, so I plugged it into one of the other
ports (including the port that the working PC was plugged into). Still no luck.

Next, I checked Device Manager > Network Adapters > Intel(R) PRO/100 VE Network Connection. There is no exclamation point next to it. Plus, under Properties, it indicates that this device is working properly.

I shut down all my computers, and unplugged the dsl modem and router. I waited a few minutes and then plugged in the modem, followed by the router. Once both of those were fully booted, I turned my computers back on. Still, no connection for the problem PC.

I went back into Device Manager and uninstalled the network adapter. Following this, I went to Add Hardware. The PC found the new hardware and installed it successfully. However, immediately upon reinstalling the hardware components, the unplugged network cable icon reappeared.

Following this, I went to Run, typed "cmd" and then "ipconfig." Under Windows IP Configuration, it reads:
"Ethernet adapter Local Area Connection: Media State.........: Media Disconnected." Is this the source of the problem? If so, how do I fix this?

How sure are you that the port on the router is working? Change routers port. i mean the cable plug the cable on a different port.

Shynnie, no offense, but it makes for a faster resolution if you throughly read the OP's post before making a suggestion, as in this case the suggested solution had already been attempted.
