UTM 9.301-2
High Availability (both systems are upgraded to the latest firmware)
AP30 devices for WiFi
After the update to the latest firmware we are we are experiencing exchange sync difficulties with our iOS devices that are connected to our WiFi. The mobile devices will not sync with our Exchange server anymore. Surfing the internet works just fine.
When the mobile devices are connected tot 3G/4G or when connected to a different WiFi, for example at home, syncing just works fine.
Before or after upgrading to 9.3 we didn't change anything in our UTM configuration.
We tried rebooting the UTM's and even performed a complete shutdown. Also we powered of all AP devices for a while. No solution.
In the wireless protection log we see that two AP devices (we have 21 AP's) show up all kinds of warnings look like this:
kernel: [143074.290000] rt305x-esw 10110000.esw: link changed 0x11
We haven't got a clue if this has to do something with it, but also these warnings are showing up since the update.
Anyone familiar with this problem, and maybe more important, is there a solution?
