q, then the same frequency is used as a part of channel list (it replaces t=
he channel list supported by the device)
It means if the freq is set to 5GHz, the supplicant will not include any 2.=
4GHz channels in the channel list in GO negotiation frames.
This can lead to Interoperability issue. One such device seen until now nex=
us 5.
Is there a way to indicate the preferred channel but keep the channel list =
intact ? So that we can preferably go to 5GHz without any interoperability =
issue?
Thanks
