Tenho um PC com Windows 11 e Ubuntu 22.04 dual boot. Atualizei o BIOS recentemente. Depois disso, o WiFi no Ubuntu não funciona. Ele não está encontrando nenhuma rede possível para se conectar. Ele funciona normalmente no Windows, e a conexão Ethernet funciona bem.
Aqui estão algumas verificações:

O ethernet mostra disponível quando conectado. Não tenho certeza do que se trata o docker. Eu o usei há um tempo.
