My company has a ZD1100 and hasn't upgrade the firmware after the deployment, the firmware is still using 220.127.116.11 build 8.
I would like to upgrade the firmware to the most update version 18.104.22.168.14 and follow the upgrade path. However, when I upgrade to 22.214.171.124.3 and 126.96.36.199.16, I found the built-in hotspot login web page cannot connect again in both version. After downgrade back to 188.8.131.52 build 8, it can connect again. Anyone has idea and how to solve this problem?
Thanks in advance!!
