Hi, does anyone know why my Archer C24 is not detecting the 5Ghz of our main router. I would like to use the C24 as wifi extender, however it only detects the 2.5ghz. All of my devices are detecting the 5Ghz. I tried putting the SSID and PASSWORD manually but no luck at all. I've watched a youtube tutorial wherein he just changed the channel of the 5Ghz settings through the ADVANCE settings but when I access the WEB GUI, there no such thing that exist. The settings I see are very limited settings.
