Recently was alerted by Tether App that my AX10 has new firmware to update. Everytime I click update and download, it will stop at around 41% then failed and the network disconnected. I need to totally factory reset to make it recover to function. Same experience when I tried to upgrade via 192.168.0.1 over PC, even I plug the LAN cable directly to PC for such process. I have checked on the Tplink official site for a download copy for that firmware, but indeed not as update as the router App indicated. 

Does anyone have idea on it? 

Thanks!
