networks are highly RSSI sensitive, so it is still possible for IWD to
prefer 2.4Ghz APs in certain circumstances.
* - BandModifier6Ghz
- Values: floating point value (default: **1.0**)
Increase or decrease the preference for 6GHz access points by increasing
or decreasing the value of this modifier. Since 6GHz networks are highly
RSSI sensitive, this gives an option to prefer 6GHz APs over 5GHz APs.
