Recentemente, atualizei meu sistema operacional de 12,10 para 13,04, funcionando bem.
Eu não estava enfrentando esse problema até hoje, mas não consigo me conectar a um determinado WiFi pela manhã. Eu tenho dois WiFi aqui & amp; Eu consigo me conectar a outro.
Quanto ao WiFi, não há problema, já que outras pessoas que estão usando o Windows podem se conectar bem com isso. Como resolver esse problema eu não sei?
Observação - Eu reiniciei o Wi-Fi e o sistema duas vezes para resolver esse problema.
