wpa_supplicant/wpa_supplicant.conf describes these parameters.

If you are using a driver that does not use internal BSS selection,
setting freq_list with only 2.4 GHz frequencies would prevent connection
on the 5 GHz band. Please also note that there is a "SET setband
<AUTO/5G/2G>" control interface command.
