I have AT&T Fiber and I detest AT&T’s residential gateway. Gigabit up and down was great! Especially if transferring large VM disks up to Azure cloud. I've since moved, but Fiber sure was nice and wish I still had it. That was back in 2017 so things might have changed/improved since then. To fix that I disabled ALL firewall options on the 5268AC.

Quick specs: - 2 phone lines - 1 ONT broadband - 4 ethernet ports. Happy to work something out! Hoping to find this a new home especially during the stay-at-home orders in the Bay Area. Works perfectly, but I upgraded to AT&T Fiber and have no use for this anymore! It's a modem + router combo, so you don't have to buy those pieces separately.
