Conexão Wifi Instável Ubuntu 14.04

9

Eu li outras perguntas no askUbuntu, mas não consegui resolver o problema, pois sou novo no Linux.

O problema é que a conexão Wifi no Ubuntu 14.04 é instável. Ele se conecta ao wifi por um tempo, mas após 5 minutos, simplesmente não consegue encontrar a maioria das redes (encontra algumas delas).

Acabei de comprar no Mouse Computer. Mas como é estável no Windows 8.1 (inicialização dupla), não parece ser um problema de hardware.

Eu tentei as soluções abaixo.

  1. Adicione "opções iwlwifi 11n_disabled = 1" em /etc/modprobe.d/iwlwifi.conf

  2. Ignorar IPv6

  3. Reinicie o NetworkManager

Nenhum deles resolveu o problema.

Abaixo segue as informações do meu Ubuntu.

    ======== Done ========

Agradeço antecipadamente.

Aliás, estou estudando o Ubuntu porque achei mais divertido do que tentar lidar com o Windows. Eu poderia decidir mudar minha plataforma principal para o Ubuntu por causa da comunidade Ask Ubuntu. Obrigado a todos os geeks do Ubuntu.

Percebi isso quando uso o WPA para conectar-se ao roteador. Tente usar o WPA2 - ele funciona bem para mim agora.

Eu sugiro que você tente um parâmetro de driver. Por favor, abra um terminal e faça:

sudo -i
echo "options rtl8723be fwlps=0"  >  /etc/modprobe.d/rtl8723be.conf
modprobe -r rtl8723be
modprobe rtl8723be
exit

Pode levar uma reinicialização. Alguma melhoria?

Muito obrigado! Funcionou e agora eu tenho uma conexão estável! Mas parece mais lento do que deveria (ou comparado com o Windows).

Bem, parece que foi porque eu desabilitei o IPv6. Vou testar isso amanhã.

Resolveu todos os problemas! Muito obrigado pela sua ajuda. Você gostaria de me explicar qual foi a causa do problema? Estou tentando descobrir sozinho, mas não consigo encontrar informações.

Eu adicionei as seguintes linhas em /etc/modprobe.d/iwlwifi.conf:

options iwlwifi 11n_disable=1

options iwlwifi swcrypto=1

e o bug se foi!

Você tem um adaptador sem fio diferente. Esta resposta não é relevante.

Eu nunca postei o que é meu adaptador de rede. Não assuma antes da mão. Pode haver mais soluções para esse problema. Eu fiz um comando "lshw -C network" e meu adaptador de rede é "RTL8723BE PCIe Wireless Network Adapter". É o mesmo da pergunta Antes de comentar primeiro "pense".

Mas os comandos que você postou como um iwlwifimódulo de configuração de resposta , que é um driver para os adaptadores sem fio Intel. Não afeta os adaptadores Realtek de forma alguma.
