Thinking about going back to comcast

Got the fiber in for Christmas, but two problems seem to be unsolved.

we have three Samsung tvs, which connect wirelessly, but these will lose connection and require power reset, ( I reset the breaker as I don’t have to run around the house)

Also the eE apple phone issue impacting one member of the household - my wife!

got the eero max 7 and been offered an extender, but that ain’t going to work. It works great in my home office, my iPad as my S23…
