I have recently got the new 5g router and am trying out att tv because i can run 20 devices on the home network. It is set up for the host ip of 188.8.131.52. After a reboot of the router the host ip is now 184.108.40.206 and att no longer recognizes my networkas home? If I switch it too many times (4 times a year) I can only stream 3 devices. i ls there a way that t mobe can keep the 172 ip address static or change it back so i do not have to reset my home location again?
