Sorry to hear about the issues you ran into. We also started the semester with

The challenge with testing FT, either "enabled" or "adaptive" is that it will
most likely work with the few devices you can test with, but the minute you
enable it and expose it to all your client devices, there will be some that
will just not play nice. At that point you either revert your

Similar to others, we also broadcast our main SSIDs outdoors. I think it is the

For those of you on or considering 8.10., be aware of this bug:
CSCvt38486:
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvt38486
This was actually brought up a couple of months ago on subject "WLC 8.10.121
Deferred". We did experience the issue with Windows clients. And testing on
they wouldn't join the controller.
Only 1 eventually joined after more than an hour. I wouldn't recommend that
version for now. All AP's were 2802's.

Not sure if everyone saw the deferral of 8.10.121.0 There is a single bug that
is fixed on 8.10.122.0 Must be bad enough for Cisco to decide to pull
8.10.121.0 off the suggested list of releases.
