AT&T is abhorrent! Costs a fortune, service is sporadic at best and nothing is ever done to improve things. 99% of the phone reps don't know their ass from their elbow!
The AT&T U-Verse slows down when using multiple internet devices and trying to view multiple TV's. I had to switch to DirecTV for the TV service. I've had many intermittent connectivity issues (Ethernet connection drops). The modem was replaced & the issue still keeps happening. Based on my negative experience I would not recommend this service.
