I had to switch to AT&T U-verse because Comcast hasn't fixed the problem were my modem was cutting out every hour for the last month. I had my lines checked like 8 times, and the modem replaced 3 times. The Comcast technician told me there was a problem with a module on the pole, but he wasn't allowed to fix it because it was a maintenance function. After waiting a month ( calling the Comcast tech support every 3 days for a month), I just couldn't take it any more, so I switched to AT&T. Unfortunately, there are no other ISP's that service this area.
With Comcast my latency while playing ESO was always between 50 and 90 ms, but with AT&T my latency is always 100 ms or 133 ms. The game is jerky now, even though the frame rate stays between 50 and 60 fps.
I had to use Googles's DNS of 8.8.8.8 because AT&T's DNS server took 2 to 5 minutes to resolve a DNS address.
I have my router (Netgear R7000) plugged into the AT&T router because I use 802.11ac, and the AT&T router doesn't support this. My gaming computer is using a LAN line to connect to my router.
So is a latency of 100 to 133 ms normal, or are most of the you getting a latency much less than this?
The latency and frame displays can be enabled in the ESO options menu.
