RTL8723BE não está funcionando no Ubuntu 14.04.3

0

A conexão Wi-Fi era fraca e desconectava com frequência, então eu segui os passos em link1 . O problema não foi resolvido, então eu tentei link2 . Infelizmente desta vez wi-fi não funciona em todos os .. Ethernet funciona muito bem. Tudo o que sei é que o kernel do Linux foi atualizado depois que eu tentei o link2 de 3.19.0-25.26 para 3.19.0-42.48

A saída do script de informações sem fio é aqui

Precisa de ajuda para fazer a placa de rede funcionar. Obrigado antecipadamente!

Atualização:

Eu iniciei a minha versão anterior do kernel 3.19.0-25 em vez do último 3.19.0-42 e o wifi parece estar funcionando! É instável embora!

Perguntas:

  1. Eu quero remover o kernel mais recente onde tive problemas com o driver, já que não preciso mais dele, como faço isso?

  2. O wifi está instável e continua desconectando enquanto eu me afasto do roteador, alguma correção para isso?

Olá,

Eu tenho a mesma placa sem fio e também tive problemas com o Wi-Fi após as atualizações.

Estabeleça uma conexão de internet temporária (com o cabo ethernet), abra um terminal e tente estes comandos.

sudo apt-get install build-essential git
git clone https://github.com/lwfinger/rtlwifi_new/
cd rtlwifi_new
make
sudo make install

Depois de fazer isso, reinicie e seu Wi-Fi deve estar funcionando.

Quando isso não resolver seu problema, tente o seguinte:

Acesse o BIOS e desative a inicialização segura!

Talvez o seu sistema não esteja permitindo a sua placa sem fio.

Espero ter ajudado! -orion -
