I have my 2.4 and 5 Ghz networks separate because not all my devices can see the 5 Ghz, and the signal drops off too fast with distance and obstructions. I don't care if it's "not recommended". It's how I want/need it.
Problem is, the devices I have that WON'T DO 5 Ghz don't see the 2.4 Ghz at all. As far as I can tell it is supposed to be broadcasting the name. But I can't see it. I can't even connect to it if I manually input the SSID and pasword.
I seriously HATE companies that decide what I can and can't do on my system.
