Problemas de Wifi com o TP-Link WN822N (Ubuntu 13.10)

5

Estou tendo um pouco de dificuldade com meu wifi no Ubuntu 13.10. Eu nunca usei Ubuntu ou Linux antes. Acabei de instalá-lo no meu novo PC e estou usando um adaptador de rede sem fio TP-Link WN822N USB para executar minha internet. O problema é que a minha internet continua em espera ... Ou seja, a conexão está lá e aparentemente funcionando, no entanto, depois de cerca de 5 minutos ou assim ele simplesmente pára de fazer qualquer coisa (sem realmente desistir). Eu apenas desconecto, reconecto e depois ele funciona novamente por mais 5 minutos, enxágue e repita.

Alguém tem alguma idéia sobre como eu posso consertar isso?

Eu tive o mesmo problema. O driver RTL não é tão bom, então, felizmente, algumas pessoas muito inteligentes encontraram uma boa solução; Acabei de instalá-lo e estou conectando solidamente sem perder ou desistir. Siga estes links, leia atentamente e aplique: "Procure primeiro entender". (- Suzanne Brown). Sorrisos esperam por você.

link (mais fácil de seguir, mas leia os outros para ajudá-lo a entender o que você estão fazendo.)

Esta não é uma resposta , mas ajudará a solucionar problemas com informações importantes, e a mensagem é muito longa para ser colocada nos comentários. Desculpa aí.

VERSÃO AUTOMÁTICA: (usa um script)

Para ajudar na solução de problemas de sua conexão sem fio, você pode adicionar algumas informações importantes executando um script simples.

  1. Faça o download: wificheck.sh
  2. Coloque o arquivo na sua pasta HOME ( ~/ ou /home/username )
  3. Abra um terminal (CTRL-ALT-T)
  4. Execute o script (a pergunta está em francês, mas responda "y" para sim):

    sudo bash wificheck.sh && sudo chmod 777 wificheck.log
    
  5. Abra o arquivo recém-criado wificheck.log e poste o conteúdo em Askubuntu.com ou Ubuntuforums.org

Ele contém todas as informações sobre o seu hardware / software relacionado a wi-fi.

VERSÃO MANUAL: (usa linhas de comando, copiar e colar e editor de texto)

Agora, isso fará o mesmo que o script (= fornecer informações úteis para solucionar problemas de conexão sem fio), mas sem um script. Você fará tudo manualmente com as linhas de comando. Cole o retorno de cada comando em um arquivo de texto ou no segmento que você abriu.
