I use a cable co. for the phone etc. This flashing light worked fine. But here's the thing I want everybody to know. The old modem had a separate router. probably more powerful than the one they replaced it with, which has the modem and router in one. The phone with its flashing light would continuously shut off indiscriminately with anyone even calling. (Is that weird?) This went on for over two weeks with dozens of calls to the co. (from my cell, of course) and finally a senior service tech came here yesterday. He fixed the problem. The flashing light cannot be used. It had to be disconnected because the new modem can't handle the power needed. See, I have 9 phones on the 1 line, upstairs, downstairs, and workshop, and now without the light, they all work fine again even with the less powerful modem.
