Hi everyone - Here's the scenario:

ATT Gigapower 1Gb Service

Speeds connected directly to modem are about 990/990

Great huh?

Well, it was, I was getting full AC for months - now - I'm getting 45/150.

I can verify it's NOT the modem and or ethernet cable between the modem and this router.

I have set the router back to stock, no change.

Hardwire test from router to laptop = same results - around 45 down 150 up.

Anyone else run into this? I should note the router is about a year old, and this is my first go at TP Link

Please, and by no means is this egotistical, but I am a network engineer and have done everything that I know to do, to this thing. 

TIA.
