Fantastic team and great coverage

on September 28, 2019

AT&T Internet

Absolutely fantastic! Tech came out to help install and, due to the wiring in our apt, it took a while to find the correct outlets. But he was so patient and helpful and kind, really going above and beyond to make sure things got set up so I could have the level of coverage needed to qualify for work from home. Truly amazing guy, I honestly can't speak highly enough of him. He kept trying long after I suspect most would have given up. Huge THANK YOU to AT&T for the coverage at the right price (literally half the price of the competitor in this area), and more importantly for having such an amazing guy on your team. Thank you.

Excellent service

AT&T Internet

I received my letter of approval for internet service thru the Access AT&T program. I called to set up service and spoke with a rep. She was so friendly and helpful. She was pleasant to speak with and very knowledgeable about my questions. She made sure I understood everything she said. She kept me informed on what she was doing in the process of setting up my account. She transferred me to another agent to set up my service and have a tech come out to install a phone jack. He was very efficient and professional and very friendly. He made sure all of my questions and concerns were answered. He was extremely polite and personable. I've had this service in the past and am extremely delighted that my area is covered to use their service again. My appointment and equipment is scheduled for Friday, just 5 days from my initial call. I am grateful AT&T offer this service, the same service as for those paying full price receive. It's a blessing to those of us on a fixed income can have the reliable and easy to use internet in today's times so we may stay connected and help with the stay at home request during virus epidemic. I felt like I was given the same respect as anyone else, even with receiving the discount rates. Thank you AT&T for making the effort to keep things simple and quick in setting up my account.

Great Speeds

on December 14, 2015


Signed up for Mediacom after having a very slow and nonfunctioning DSL connection. Had to wait for them to run a line to my area but all in all well worth getting cable connection. Right from start have had a 58 Mbps download and 6 Mbps upload consistently. What I signed for is 50 Mbps/5 Mbps so am receiving a little higher rate. Have only had 2 calls to support and the connection was fixed quickly. Both times it was in their plant so no one needed to come to house.

Could be better

on January 09, 2020


I use Mediacom at my office in Forsyth, MO. It was the only service I had access to when I signed up. It sometimes runs really slow and I don't know why. They did do an update a year or so ago and that did help some, but there are times when it's still slow. It's expensive too. I haven't looked to see if I can do better, so I need to do that.
