Eu tentei usar o e funciona relativamente bem com poucos problemas. Ontem eu tentei remover / reinstalar o driver e depois que eu não posso ativar o WiFi no meu Lenovo ThinkPad E540.

Se eu tentar baixar os drivers do GitHub e, em seguida, limpar, fazer, fazer o sudo isntall, sudo modprobe rtl8723be, recebo um erro:

Como @ chili555 perguntou, aqui está o que eu recebo: cat / var / log / syslog | grep -e rtl -e etwork | tail -n25

Agora, estou trabalhando com a conexão com fio, mas não tenho a opção de ativar / desativar a conexão sem fio.

Além disso, como eu disse em outra pergunta, de tempos em tempos, perdi a conexão por algum motivo e depois disso não consigo me reconectar à rede. Eu tenho que reiniciar e depois disso eu tenho WiFi.

I can confirm that chili555 method works for me. But I have strange problem - if I'm > connected and if I lost connection for some reasons, after that I can't connect to > any other(or same) WiFi. is anybody else having the same problem? Lenovo ThinkPad > E540.

Agradecemos antecipadamente:)

UPDATE Eu seleciono a versão anterior do kernel:

Linux metodiew 3.8.0-19-generic #30-Ubuntu SMP Wed May 1 16:35:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

e agora eu tenho conexão WiFi. Vai atualizar a questão se eu ainda tiver problemas com a perda de conexão de tempos em tempos.

Problema resolvido pelo consulente:

Cite a pergunta:

I select earlier kernel version:

Linux metodiew 3.8.0-19-generic #30-Ubuntu SMP Wed May 1 16:35:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

and now I have WiFi connection. Will update question if I still have problems with lost connection from time to time.

Isso é para deixar claro que a questão foi resolvida, pelo menos até que o usuário responda por si mesmo. Eu vou deletar assim que isso acontecer.
