Tried this and discovered some issues.
The 160 MHz option was missing for both 5 GHz bands.
Noticed a lack of speeds on the 5GHz bands and discovered both 5GHz bands were on 20 MHz.
Set them to 20/40/80 MHz and they were still at 20 MHz.
Set to 80 MHz then they stayed on 80 MHz.
Did a complete reset of the router and all bands were set to 20 MHz with no 160 option.
Rolled back to 22127.
