Maybe doing another reset could help then? Using the physical button, the 30 30 30 method.
- When the router is on, press the reset button and hold it for 30 seconds.
- While holding down the reset button, turn off the power of the router and hold down the reset button for 30 seconds
- While holding down the reset button, turn on the power to the unit again and hold for another 30 seconds
Old trick, but might just work

Basically keep holding reset for 90 secs while on - off - on
