I have upgraded my Vsz to 184.108.40.206.510 and upgraded the APs to 220.127.116.11.709. After the upgrade i noticed that almost every AP had a high percentage of connection errors. I let it go for several days and thought i still had a lot of clients connected so it must be working. In the events I see a lot of Force DHCP disconnects. I did not make any changes to that but did double check the settings. Some wlans were not enabled and some set to anywhere from 5-15 seconds. Downgraded the firmware to 18.104.22.168.1026 and the connection errors went away. Has anyone seen this and have any ideas why i am seeing this.
