Hello, I might think that this thread has already shown, but I need help. I really don't know how this works. My ethernet cable does not glow when pluggled in. My computer had a virus recently and it blocked the internet, but now the virus is out, but i can't use the internet. I believe it is the ethernet because it does not glow and because in the modem it does not show as connected. Its not the cable because it works with other computers. Can you please help me. Thank You
