I have been using 1x at our high school for a few years. I cannot be sure if it's related to XOS updates or Windows updates, but when we came back to school this summer I ran into problems with clients (mostly win7) reverting to an unauth state (preauth topology/vlan) mid day.
the problem is that the connection does not reset when that topology changes, so my users are left with a DHCP address from the authenticated topology, which is no longer egressing on the port.
My work around had been to ask my users to unplug/replug the network cable in these cases, but now I have just made the auth topology be the same as the unauth topology.
There are a number of windows hotfixes related to 1x from Microsoft released going back to 2013. I know some take care of a problem at startup that is causing 1x timeouts due to Windows not acknowledging a successful auth.
Have anyone figured the best mix of hotfixes to apply to windows clients to make 1x stable?
Thanks!
