that is the switch . the cable that i think is faulty is a flat ethernet cable , and when plugged into the switch and the amazon box , the corresponding light on the switch , doesnt light , as if there is no activity , and the amazon box says there is no internet connection . i will test the port on the switch with a new cable . The only thing that was puzzling me is that i know the faulty cable was working in the morning , but hasnt worked since , thanks for all your help , im nearly there now .
