Do you have the bug id for “ show stopping bug”? I have tried to look up the bug details for the Radius Auth bug in 7.6.120.0 but it doesn’t say if it affects 8510s. We just upgraded our 8510s to 7.6 MR1 and have run into several client issues. Planning to upgrade to 7.6MR2 but want to make sure I understand the risks. Thanks in advance.

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.
