Hi, 

You can use "wl chanspec" command for this. For ex: if you want to set channel 42 for 80MHz mode, you can use the command "wl chanspec 36/80". You can find more information in the WiFi CLM Regulatory Manual in section 4.2.4.1 Channels Testing and Channel Availability by Country (Tier-1). I provide the link for the same -

But, do change the band to 5GHz as 802.11ac operates in 5GHz. You can do this by "wl band a", by default it's in auto mode.

Thanks

Aditi
