I will be opening a ticket with cambium but I wanted to let everyone know this issues we just came across.
I updated all our 450 APs to 14.1.1 yesterday. On our 5Ghz 450s we use the 5.4 band. On all these APs the "Alternate Frequency Carrier 1" and "Alternate Frequency Carrier 2" were reset to "none". when I go and set them back to what they should be, save and reboot they still come back as "none". Because of this if we experience a DFS event we have no other frequency to hop to. Additionally we have a couple APs that after the upgrade are now seeing DFS events when previously they experienced no events...ever. We live in the middle of the rocky mtns. so there really shouldn't be any events because of all the granite clouds in the way ;-) anyway, DFS seems to be broken on 14.1.1 and I wanted to let everyone know before they apply the upgrade incase you need DFS to work properly. -Sean
