I have three computers that work off of the same modem/router. And two of them work fine, and all of a sudden the third one says the network cable is unplugged. I tried a different network cable and I get the same reaction. I looked in device manager and uninstalled my network driver, reinstalled it....same problem.
You have lots of posts, and I do not want to offend you, but sometimes hitting the basics are a good idea to start with.....so....have you checked your cables to make sure they are ok? Have you tried to switch which ports they are plugged into to see if any other computer disconnects in that port? Try some control testing and let me know what happens!
