I have a router (Sky hub) that does not seem to light up the ethernet ports when I connect one cable to my computer. When I go to my network connections menu in control panel, it claims that there is no ethernet cable connected. I have no idea why it is doing this because it seemed to work just fine before. I know that the router works because the ethernet port lights up if I connect a cable from that router to another router (Belkin) and then that secondary router to my computer. I don’t think the router is broken and my drivers are not faulty because I have tried this on 3 different computers. My cables are not faulty either because I have tried 5 different cables.
