my reply to that, and my advice on this whole issue
i wish my phone would tell that, but my android does not. One of the ways that I can tell is if my ChromeCast icon appears - then I know I am at 2.4. (There are certain rooms in my house that connect at 2.4). Also, if I go outside my stone house, and disconnect and reconnect using that WI-FI icon on my android, I will connect at 2.4. Then I can come into my house and set up any smart plugs (which all use 2.4), or the Chromecast (which also uses 2.4). I must have 50 different devices in my house - all the smartplugs use only 2.4 - I can't remember if the google speakers use 5.1 or not, but I know the Chromecast use 2.4. My LG refrigerator and LG Washer and Dryer all use 2.4. (But, I have found that each time, if I go outside - disconnect and reconnect - then I can do the setup). And once it is set up, then I don't have to worry about the issue again. (Except for Chromecast - which requires that I go out of the rooms that the televisions are in - until the Chromecast Icon appears on my phone (an interior stair case, my bedroom, or outside my house - then I can see the Chromecast icon - cast whatever it is I want to cast, then I can come back in my house and watch the show).
It wasn't me that discovered this - it was my teenagers. I didn't believe them when they first told me. I spent hours trying to figure out why the chromecast button appears once in a while, but not usually. They told me if they go upstairs - then they can do it, then they come back downstairs. I've been doing this for well over a year, and it always works. In fact, I just installed a new chromecast on an attic tv - and the same thing. I go out of the attic - down to my bedroom, then I can see the cast button, and then I can proceed.
Strange, but true.
So regardless of what people tell you that this should happen or not, it does. I have 4 teenagers - I lived through the whole covid thing with all of us on and off the network - and I have learned how to deal with this system - as awkward and strange as that answer is. (I haven't tried the foil. I think I will do that now to see if I have a foil lined box that I can put my phone in and access the tv from the room the tv is in.
