why are all my 2.4G Light Weight Access Points running on channel 1

[Richard Bradfield]

looking into a problem at one of my sites with 49 APs (1242s) using WLC 4402 running 7.0.250.0 all channels are on 1, why is this when controlled by the WLC? has the algorithm changed with newer software, please see enclosed for the DCA screenshot, DCA done every 12 hours. Note there is a university next to this site so always had a lot of interference has that got something to do with it?

Untick "Avoid Cisco AP load". 

Untick "Avoid Persistence Non-Wifi Interference".

I think this is a buggy  behavior, If you have TAC support reach them & check any known bug ID for this. This is not exact the same, but similar behaviour in CH36 in 5GHz

Remove the CH1 from DCA list & see AP assign CH6 & CH11. Then readd CH1 to the list.
