Hi everyone,
About 3 or 4 weeks ago, just before our spring break, I upgraded our entire district wireless IAP infrastructure (roughly 1900 APs) from 6.4.2.0-4.1.1.1_46936 to 6.4.2.3-4.1.1.2_48114. A day or two after spring break was over, we started having some issues where random APs seemed to stop passing DHCP traffic. Clients were getting 169.254 (automatic private) IP addresses, and couldn't connect to the network. Rebooting the AP would solve the problem for a couple of days. I opened a TAC case (#1650699 if anyone with TAC access wants to check out the history), but then the problem became a major epidemic. Last week, while I was at Atmosphere 2015, I had to remove in (thank goodness for VPNs) and initiate a district-wide downgrade (thank goodness for Airwave!) back to 6.4.2.0-4.1.1.1_46936. Since then, we've had no problems.
I suspect that perhaps this could be another reason why 6.4.2.3-4.1.1.2_48114 was pulled...??
