I have internet issues with my Belkin H (brand new) router. I can connect and stay online directly, but when I connect the router, it will connect and almost instantly disconnect from internet. I have had this router about 2 months with no problems, wondering if I need a new cat cable. I have a cat5e that appears to be in good shape. But I can't think of any other reason I can't stay online with the router connected. Will a new cat cable solve the problem?
