So my Dad uses the same WiFi as me and on his Network properties it says the Network band is 5GHz yet on mine it says 2.4GHz. I've recently bought an 802.11ac adapter to make sure I can use 5GHz. I have searched on command prompt using netsh wlan show drivers and it confirms I can use 5GHz. I have tried setting the mode to 802.11ac only but my network just disappears and only reappears when I set it to 802.11b/g/n or Auto. Any help would be appreciated, thanks
