We have WOW here competing with spectrum and AT&T. it was great to have a lower priced regional service but they have since been trying to ape the bigger providers by adding data caps and increasing their prices.
I threatened to switch to Spectrum a couple of years ago because they were offering new users $20 for their 100 Mbps connection and charging me $60, so they gave me a $30 plan which expired this month and now im back to $60. I can call them and threaten to quit again or just switch to spectrum because they also offer $30 plans to new costumers but this time WOW can put me in their data cap plans even if they do let me keep my $30 plan.
So yeah, even regional services are lame, but they might be your best bet. Just google ISP providers in atlanta and pick anyone that gives you a good price per performance. dont bother looking at reviews, all ISPs have trash ratings because people only review them when they have issues. Just give them a shot for a couple of months.
Atlantic Nexus comes up first when I search ISPs in Atlanta, and has surprisingly good reviews. But thats probably because they are new. Again, dont discount a provider if they have bad ratings, but good ratings are a good sign.
