I have an edimax br-6240wg wireless router. It started giving me real trouble - the computer will tell me a network cable is unplugged, tries to get a new ip address, and then almost immediately says a cable is unplugged, ad infinitum. Meanwhile, the wireless seems to work since other devices can connect to it, unless it'd during the time that my computer is being used and giving me all the cable unplugged problems. So to summarize: on my computer it won't work, but the wireless works for others, unless my computer is in use. I thought it may be the ethernet card that's the problem, but when I connect to the internet via a regular dsl modem, the internet works fine. So it doesn't seem to be the computer. I'm wondering if it's not a virus. Can you help?
