Eu tenho um notebook HP Pavilion G7 e, quando uso o ubuntu, ele inicializa bem e, quando eu chego, não consigo me conectar ao wifi. Eu sei o problema porque ele diz algo como "desconectado por switch de hardware". Eu tentei ligar meu interruptor de hardware, mas ele não quer ligar (é um botão que deve acender uma luz azul para mostrar que está ligado, mas brilha uma luz laranja que significa que está desligado).
Você pode tentar usar o seguinte comando no terminal; rfkill desbloquear wifi. Depois disso, desligue o seu switch wifi e volte a ligá-lo. Se isso não funcionar, vá para a configuração de rede no canto superior direito da tela com os ícones de notificação. desabilitar a rede e fazer o comando "rfkill desbloquear wifi", depois que renate a rede.
Sir tente seguir este link. Seu Wifi provavelmente foi colocado na lista negra do Ubuntu. Não sei por que eles permitem isso, mas eles nos deram a solução. Veja aqui para mais detalhes.

Instalando os drivers wireless da Broadcom Como instalar a placa Broadcom / STA Wireless (BCM43XX)
up vote 7 down vote favorito
21
Estou tendo sérios problemas ao instalar os drivers da Broadcom para o Ubuntu. Funcionou perfeitamente na minha versão anterior, mas agora é impossível. Eu sou um usuário sem conhecimento prévio em Linux, então eu precisaria de explicações claras sobre make, compile, etc. Eu estava seguindo as instruções no blog seguinte, sem sorte.
Como posso ter o Broadcom BCM4311 Wireless funcionando?
Alguém pode me ajudar?
Edit: Para o comando: lspci | grep Network , recebo a seguinte mensagem:
06:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
For the command: iwconfig, i get the following:
lo no wireless extensions. eth0 no wireless extensions.
Quando sigo os seguintes passos (do link acima), há uma mensagem de erro NO:
1. Abra o 'Ubuntu Software Center' e procure por bcm
2. Desinstale o bcm-kernel-source package
3. Verifique se os pacotes firmware-b43-installer e b43-fwcutter estão instalados
Em seguida, digite no terminal:
cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl'
(você pode querer copiar isso) e ver se o termo lista negra bcm43xx está lá se for, digite
cd /etc/modprobe.d/ and then sudo gedit blacklist.conf
coloque um # na frente da linha: blacklist bcm43xx em seguida, salve o arquivo (eu estava recebendo mensagens de erro no terminal sobre não ser capaz de salvar, mas ele realmente salvou corretamente). reinicialização 'Fim do procedimento' Antes (não Ubuntu 11,04), se eu quisesse conectar sem fio, eu fui até o ícone na parte superior da tela, cliquei, mostrei TODA a rede sem fio disponível e pronto.
