hi, i tried but still the same. Now the device reset to default automatically.
Before that, the AP firmware version is 9.1 and i tried to upgrade via ZD (version 9.4)but configure in standalone mode. It seem not stable and i download from web portal and upgrade again from my local PC. It seem working fine for the first hour but after that, it become unstable and it happen like keep rebooting every 5-15mins.
Just checked the device and i can't ping at all (but LED show fast blinking). Hard reboot it and it back to default setting.
We got few units with us but all look the same. I guess it was due to software since all of them have similar issue.
