Eu tenho um notebook Kanji Tamura Duo, em que eu tinha Windows10 um tudo funcionou muito bem. Ontem eu instalei o Ubuntu 18.04 e o WiFi não funciona. Ele me permite ligá-lo e, em seguida, quando eu vou para "Select Network" fica preso em "sem redes" (eu sei que existem redes disponíveis). Eu estive procurando na internet, mas não consegui encontrar uma correção. Vou incluir algumas das saídas que tentei no caso de serem úteis. Eu já voltei para o Win10, estou deixando o piso aberto, já que há outros com o mesmo problema.

Tente desconectar qualquer coisa externa, especialmente qualquer monitor externo, e reinicie o computador. Isso resolveu o problema para mim.
