|Okay, I've done all the usual checks - cables, reset the router, renew IP address, etc.|
After running ipconfig /all in the command prompt, "Physical address" (ie. the MAC address) is displayed as FF-FF-FF-FF-FF-FF, which I know is invalid. The IP address is also invalid, but I think the bad MAC address is the cause of the problem. Without a valid MAC address, she can't connect to the network.
How do I resolve this problem?
