Before this commit, devices supporting both 2.4GHz and 5GHz would be configured for 2.4GHz by default - unless they have VHT capabilities. With this commit, channel 36 is only set when the frequency is supported. VHT isn't checked unless that is the case. Signed-off-by: Leon M. George <leon@georgemail.eu>
