Controller auto sensing power and channel question

[Cisco1619]

A few months ago we upgraded our warehouse from 1242 APs to 3502E APs. We changed 16 units, all in the same building. When we came in the next day we found out that they were all on channel 1 at their lowest power level. The WLC was set for auto negotiate for power and channel but for some reason it did not work. We had successfully changed they rest of the factory with the auto feature enabled but for some reason, the warehouse did not work properly. All APs have the same IOS and are they same model. Has anyone else seen the WLC do this and if so, what caused this? We have WiSMs mounted in a 6509 chassis as our WLC.

Thanks!

Well the only way I can see that happening is if the AP's are pretty far apart from each other where the algorithm doesn't make any changes.  Do you have an * next to the power and channel?  Its really tough to say without really knowing what your setting are and the location of the AP's.  I'm guessing you are running v7..x?

Thanks,

Scott
