We currently have ZD3050 with over 30 ZF7363 APs. I have tried updating the firmware from 9.6.1.0.15 to 9.6.2.0.13, 9.7.0.0.220, 9.7.1.0.17, 9.7.1.0.32 and 9.7.2.0.9 without success. ZD itself updates just fine, but after restarting it, all APs remain in disconnected state. The only way to get them back online is to roll back to 9.6.1.0.15. I have updated firmware on ZD many times before and have never experienced similar issue.
Regards,
M.
