Ubuntu 20.04 LTS non si collega al WiFi

Question

Ciao a tutti! Vi scrivo in quanto il mio pc non si collega al WiFi o, meglio, si collega ma dopo un po' si disconnette non ho idea del perchè, fino alla settimana scorsa funzionava. Ora mi collego usando il cellulare con hotspot oppure via ethernet. Vi posto alcuni output che potrebbero essere utili per capire il problema:
