AT&T DSL is an internet service which uses a Digital Subscriber Line to deliver a high speed internet connection to its subscribers.
DSL utilizes existing telephone lines to transmit data. Consequently internet connections delivered via AT&T DSL max out at 6Mpbs downstream and 768Kbps upstream.
I have never had a worse cable & internet service than AT&T. I just wasted a whole Saturday with not one, but two technicians and my cable television service stopped working the minute they drove away. I’m going to switch to another carrier. I just can’t take it anymore! U-Verse is always down and AT&T just doesn’t care.
