A friend of mine asked me to help him with his home network. The router he has has 2 computers connected to it by cable and a few laptops wirelessly. The issue concerns the computers wired to it.
Computer 1 can access the internet fine if Computer 2 is turned off. If Computer 2 is turned on when Computer 1 is already on, then both can access the internet. If Computer 1 is turned on while Computer 2 is already on the internet, then Computer 1 cannot get on to the internet, and receives the error message: "a network cable is unplugged".
I have tried setting up a static IP for computer 1 but that didn't change anything.
Any help would be much appreciated!
