mam nietypowy problem z WiFi, przeszukując google i forum nie potrafię znaleźć podobnego. Otóż w pewnym momencie straciłem możliwość połączenia się z Wifi. Nie jest to raczej problem routera, bo na telefonie czy laptopie z Windowsem mogę się bez problemu łączyć. Co więcej, po przeinstalowaniu systemu mogłem na nowo bez problemu się z internetem bezprzewodowo łączyć, specjalnie też robiłem restart po zainstalowaniu aktualizacji (wciąż działał), ale za trzecim razem jak włączyłem laptopa to nie potrafi się on z WiFi połączyć.
Problem komplikuje fakt, że widzę dostępne sieci, jednak po próbie połączenia się, ikonka tylko się obraca i w końcu pyta ponownie o hasło. Sieć jest zabezpieczona przez WPA/WPA2 Personal, ale nie mogę się też podlączyć do sieci niezabezpieczonej.
Dołączam wyniki poleceń znalezione w innym wątku, nie wiem na ile to będzie przydatne w moim wypadku:
