Eu sou novo no Ubuntu, dias atrás, então sou praticamente ignorante da maior parte da programação. Eu tenho tentado configurar minha rede sem fio, mas nada parece funcionar. Para obter informações adicionais, tenho um laptop G750JM. Eu instalei o driver de Additional Drivers
in Software & Updates
.
Eu usei o comando lspci
para verificar meu controlador de rede e obtive
Broadcom Limited BCM4352 802.11ac Wireless Network Adapter (rev 03)
mas quando eu verificar a conexão em iwconfig
lo no wireless extensions.
enp4s0 no wireless extensions.
Eu recebo essa saída.
Eu segui esse vídeo
link
e isso não ajudou.
Em seguida encontrei o comando service network-manager restart
que encontrei em askUbuntu
. A rede mostra a vida dizendo que a rede sem fio está desconectada e parece tentar se reconectar, mas não faz isso. Eu segui mais algumas instruções sobre o Ask Ubuntu, que também não ajudaram, apesar de terem sido habilmente escritas e fáceis de seguir.
essa é uma
Instalando os drivers wireless da Broadcom
o comando nmcli dev
fornece a saída

quando eu uso o comando sudo lshw -C network
eu recebo a saída

Eu então usei a primeira resposta nesta pergunta
