I have a computer in my house where the DSL line connects to the router. The router feeds the home computer that sits next to it and also another cable that goes to the computer in my shop. The shop is about 175' from the house. It worked great for about a year but now I keep loosing my internet connection from the shop computer, if I unplug the cable from the shop computer and plug it back in it will usually work again for a few minutes to a day or so. Is there some sort of test I can do to determine if the problem is in the cable or the router? Thanks.
