I need some help with an issue with the TP-Link AC1900 extender i just got. Got it working and have a computer hooked up to it. But then starting to have network issues. My smart tv seemed to have issues with internet connectivity. Rebooted the modem and it was fine. But also I have a couple Uverse wireless cable boxes that now lost signal, must be some problem interfering with the new TP-Link AC1900 presence. I am guessing the TP-Link AC1900 configuration has some issues. I did notice at first a conflict with first setting it up, the IP and gateway coming across the TP-Link AC1900 from the uverse wf fi was wrong. I manually put in right one on machine and that worked. Also had to manually put in the DNS suffix. SO maybe the issue is the TP-Link AC1900 configuration with not carrying over correct IPs, gateway etc.?
