I did find some other posts about other vendors having problems and to disable the Aironet Extensions. I'm currently using CKIP, CCKM, and forcing power levels for 7920 IP phones which looks like this would no longer work if I did this. I tried it though and it will not disable. I reset a WAP to factory defaults and same thing. I disable, apply changes, and it goes back to enable.
Even if I did get it to save, sounds like I'm out of luck if this is the solution.
