I have discovered a serious problem with 1142 APs after moving them to a newer controller version. They were previously ether on WISM or 3750G controllers running 7.0.240.0 or similar. I have moved them to either 2504 or 5520 controller running 8.3.112.0.
Some 1142s ported over fine and are working normally but quite a few broke completely.
It seems any that are HW revision V01 printed on the back are working 100%
I am testing others i have some v02 and v06 i think....
I have a lot of V04 APs that are now broken. If I plug into the console and manage to erase the NVRAM so that I can get them to rejoin a controller on an older software version.
There is nothing in the release notes or bugs i can find to say these are not supported!
A console output from the AP I get the following in an infinite loop.
