I have AT&T fiber. Never had any issues with it. I can run 3 TV's, 3 computers, and 3 phones, ring doorbell, 3 other outside cameras. iPad or laptop if not on my computer.
Was paying $52 a month for a crappy DSL service. Was about to switch to something else. But for some reason when I was able to go to fiber, they gave me some type of discount, and now I pay $25.25 with taxes per month.
Only issue was when I had my lawn re-sodded, they cut the line. AT& came out the same day to fix it. The guy didn't seem to happy, and made some rude comment about it. I told him to learn to bury the cable deeper other wise just fix it. The line was not run correctly to begin with. This time they ran it along the fence and next to the house instead of across the middle of the yard.
