This is weird. I upgraded my ATT fiber box about six months ago and everything transferred seamlessly (I anticipated a huge project). All Chromecast, Firestick, video game consoles, Next, etc. all immediately adapted to the upgraded ATT CyberTAN box. We had a rodent chew throw some wires and ATT had to replace. Once they did, GhZ was combined. While most things on the network have been reestablished, we cannot figure out how to cast anymore on our 2023 LG smart TV (all things worked perfectly a month ago before the change of the wires). The smart TV works for streaming, but will not pick up casting. Chrome will no longer work. Cannot cast from I-phone 15 or or brand new Lenovo. Was able to before the cable replacement. Cannot figure out what is going on?
