As I’m facing issues with connection betwenn HassIO on Raspi connected to 5Ghz WLAN and Aqara Hub M2 to 2,4 Ghz I would like to connect HassIO fix to 2,4Ghz.
I’ve edited the config, restartet host and nmcli shows:
# nmcli con show
NAME UUID TYPE DEVICE
Supervisor wlan0 6779e42c-fccf-4222-a63c-fe2d571e2ce6 wifi wlan0
HassOS default f62bf7c2-e565-49ff-bbfc-a4cf791e6add ethernet --
# nmcli con edit "Supervisor wlan0"
nmcli> print 802-11-wireless.band
802-11-wireless.band: bg
which should lead to 2,4Ghz connection from my point of view. Looking in Fritzbox it still tells me that Raspi is connected within 5Ghz band.
