In order to get 160MHz bandwidth on both my 5GHz-1 and 5GHz-2 bands, I have to manually assign the bands' channels to 36 and 160 (respectively). *However, sometime in the middle of the night EVERY NIGHT, the backhaul band changes channels to an 80MHz channel. *I haven't waited around long enough to see whether it eventually switches back to 160MHz, but why is it doing this in the first place since I've manually assigned the channels? *If I reboot the router and the nodes, both 5GHz 160MHz bands' connections return, but why is this happening in the first place? *What can I do to prevent it from happening?
