ZD3000 + ZF7363s - unable to upgrade firmware beyond 184.108.40.206.15
We currently have ZD3050 with over 30 ZF7363 APs. I have tried updating the firmware from 220.127.116.11.15 to 18.104.22.168.13, 22.214.171.124.220, 126.96.36.199.17, 188.8.131.52.32 and 184.108.40.206.9 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 220.127.116.11.15. I have updated firmware on ZD many times before and have never experienced similar issue.
