I am in need of some serious help.

My husband and I share a modem through a wired router and the other day for no reason we would start to lose the connection. We have not downloaded anything and have run our virus software constantly. We have to restart the modem and router to GET connection BACK but it will only last a few minutes. We have also replaced the router but we are now having the same issues with the new one. We are able to get around this problem by TAKING the router completely out of the picture but then my husband is the only one who can connect due to no router useage. Please help I don't have a huge knowledge of computers and I am losing my mind trying to figure this out.This is a shot in the dark but I'm thinking maybe its the network cable itself? Do you have any spare cable that you could switch out with the original? Otherwise TRY using the one your husband is using and hook it up to yours. I'm no network specialist, but I don't think it would hurt. Try this just for grins and giggles. More info would help - current and previous models of router, name of ISP, brief computer specs, etc.

Thanks!Check the CABLES first. When you have problems, can you "ping" one computer from the other? Can you "ping" the router"? If you connect your computer directly to the modem, it works?
