I had new service put in 30 days ago. Phone, Tv, and Internet and the gateway took a dump. ATT sent me another gateway, which arrived 5 days later, (no phone, tv or internet), and that was just another piece of crap. Finally after hours on my Onstar Phone CS deceided that I need a tech to come over. After checking all the wires he replaced my gateway #3 and I was up and running. The moral on this story is get a new gateway. The tech said that most gateways are customer returns, checked out, and put back in service so you really don't what you are getting, new or refurbished.
