Unable to connect Q box to internet

[Tarrind]

Web page help told me to update password - instructions followed. The box briefly connected to internet (long enough for me to see my mini box could connect to the Q box again), but then stopped again. However, it still looks like password not updated (current version shown is : Q360.000.08.00L (68x37s0)). Then I contacted the AI help robot by phone. It told me to cold boot and reinstall software (by using a long press on standby button). Completed this. Still not able to connect to my router. I have also performed many connection resets, and twice I have had short lived reconnections to the router (an EE smart hub 6 plus).

Any suggestions on what to try next would be greatly appreciated.
