You bought fiber internet from the devil what were you thinking?
I have AT&T Fiber too, although not gig as it is a waste of money just my wife and I. We live within a 1TB cap easily on our 50/50 plan for $40/month. My other choices were:
Frontier VDSL2: Best speed available 12/2, run by a bunch of jerks too
Spectrum: Up to 300/20 available, but crappy tech support; slow DNS (including Google, OpenDNS, etc. -- I think they are under constant DDoS on port 53 or something. Used to run local caching nameserver when I had this in the past); streaming problems; service goes out when it rains a lot, gets too hot, someone sneezes, etc.; and run by as-big or bigger jerks than AT&T
It was an easy decision to go with AT&T. I have AT&T wireless because Verizon, T-Mobile, Sprint all have coverage problems in specific areas I frequent. I've had it for years, and I've never had any issues. So far, by Fiber internet service is the same.
