Hello, I have uploaded new AP firmware to my Smartzone. I am now going to the zone and selecting 'Change AP firmware'. However I only receive this blank popup page with no option to select the firmware to upgrade to. Am I missing something ? n.b. I have tried multiple different web browsers in case it was a GUI rendering problem but see the same result.
It seems you only uploaded the new controller firmware file to v/SZ but not yet hit "Upgrade" or "Backup & Upgrade".
Hit the "Upgrade" or "Backup & upgrade"(recommended) button and complete the controller firmware upgrade. Doing so will also upgrade AP firmware and then you can go to AP Zone >> More >> Change firmware and you should be able to see 220.127.116.11.698 AP version in the available AP firmware.
