I have two different named SSID’s, 2,4GHz and 5Ghz. Devices connected to 2,4 are visible ONLY by others wifi devices when they are connected to 5 band.

for example I can cast from phone to Android TV (connected to 5ghz) only when phone is on 2,4 ghz band…

why its like that and how to fix it

wired connected pc to router does not have these issues
