No meu computador principal, executando o Ubuntu 18.04, posso me conectar normalmente à minha rede doméstica.
Instalei recentemente o Ubuntu 18.04 em outro computador, a rede está funcionando. Ele pode ver as redes Wi-Fi dos meus vizinhos, mas não exibe minha rede doméstica na lista de redes.
Eu já experimentei o Ubuntu e o Ubuntu Mate e isso está acontecendo em ambas as distribuições. Alguém tem uma idéia do que pode estar acontecendo?
Aqui está a saída de lspci -nnk , pois lspci -nnk | grep -iA3 net não produz saída:
