I have upgraded my Vsz to 22.214.171.124.510 and upgraded the APs to 126.96.36.199.709. 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 188.8.131.52.1026 and the connection errors went away. Has anyone seen this and have any ideas why i am seeing this.
