If I connect my router directly to the main DSL cable, my internet works just fine. If I connect it to a telephone, it also works. When I try to use a splitter to use both the internet and the telephone, only the telephone works - also tried three different splitters, new cables, the router does not even see a DSL connection. What could cause this issue?
