In my house we have a cable modem that feeds to two computers through a linksys router. It uses Netgear Phonline adapters to get to each computer. One computer is running windows ME, and there is no problem there. However, on the other computer with Windows XP, there is some crazy stuff going on. Every day after about 5 or 6 p.m. it starts happening. The "Network Cable Unplugged" message appears randomly and with it the network and internet access goes out. It can happen in 5 seconds - 1minute intervals. Again, it only happens on the one computer, and only at night. Any ideas?
