Hi. Ok, so basically, I have my computer connected to a router, which is connected to my modem. My internet works without problems. HOWEVER, whenever I connect my modem DIRECTLY to my computer, the connnection is not detected. On my modem (I have an arris modem), a light with word 'link' blinks to detect transfer. When it is directly connected to my computer, this light stays off. Also, on my computer, it tells me that the local area connection (I am using windows xp) is not connected because the ethernet cable is "unplugged". What could this be? Why can't my computer connect to my modem directly?
