Not a lot of help, but -- we are on 7.6.120.0 with 1142s in our mix (about 55%
of 3800 APs). We have not seen this problem.

Subject: [WIRELESS-LAN] Radios Shutdown After WLC Upgrade
Hello,
Wondering if anyone else running Cisco has run into this:
After upgrading controllers from 7.4.121.0 to 7.6.120.6 about 3% (~100) of our
AP's joined the WLC but both radios are shut down. If you try to re-enable the
radios via the WLC or directly SSH'ed to the AP they auto-disable again.
Disabling, and re-enabling the switchport does nothing, and rebooting the AP
does nothing. Intentionally disabling one radio on the AP does not help
either. The switch shows it is providing 15.4 watts of PoE.
We are split evenly between 1142's, 3500's, and 3600's and have mostly Cisco
switches, but have only seen the issue on some 1142 series AP's, and some
Foundry PoE switches. In some cases another 1142 is working fine on the same
switch, and if we walk over and connect another 1142 it works fine on the same
port. The current work-around is to move AP's back to a WLC on 7.4 code.
I have a TAC case open, and 7.6.120.6 is a special build but we were encouraged
to go to it in order to avoid the catastrophic web-auth, and severe RADIUS-NAC
bugs.
Let me know if you have any suggestions.
Thanks,
