This might be a stupid question but here it is. I have a Scientific Atlanta cable modem with the Ethernet line hooked to a Netgear wireless router. On the modem it has lights for Power, DS, US and Online, these 4 lights stay on solid all the time, Then it has lights for Link, Tel 1 and Tel 2. I don't have a phone line hooked up so the phone lights stay dark. The link light stays blinking all the time, When the link light is blinking it indicates that there is traffic to and from my PC and when the link light stays solid or not blinking it indicates that there is connection but there is no traffic back and forth, So when I shut down my PC the link light should stop blinking and go solid but when I shut down my PC the link light only pauses for a second and then goes back to blinking mode. If my PC is shut down there should be no back and forth traffic so why does this link light continue to indicate traffic??????
