Ubuntu 16.04 - degradando o desempenho sem fio

1

Eu tenho lido vários outros passos sobre esta questão e tentei várias coisas, mas ainda o mesmo problema.

Eu fiz o upgrade de 14.04 para 16.04 - e foi aí que os problemas começaram. Minha conexão sem fio é perfeita - o speedtest.net mostra velocidades de download de até 65 Mbps. Um pouco mais tarde (cerca de 10 a 20 minutos - dependendo do uso) quando percebo que minha conexão com a Internet se deteriorou - a mesma verificação de velocidade retorna velocidades tão baixas quanto 0,5 Mbps. Se eu continuar, ele falhará completamente em algum momento, enquanto o wifi se desconecta, e então continuamente tenta se reconectar sem sucesso.

Se eu executar esses comandos

    sudo modprobe -r rt2800pci
    sudo modprobe -v rt2800pci

A conexão está perfeita novamente. Por mais 10 ou 20 minutos, e então o mesmo acontece novamente até eu resetar novamente.

Quaisquer pensamentos sobre o que poderia estar causando isso, ou como eu posso fazer a 'correção' permanente seria muito apreciada.

Meu "wireless-info" retorna o seguinte

Obrigado

... Eu quero colocar isso no topo novamente

Finalmente, depois de mais de uma semana de frustração - acho que encontrei uma solução para essa questão - há mais alguém lá fora que quer arrancar os cabelos, não faça isso.

Parece que a solução desse problema específico - que anda de mãos dadas com o incômodo

rt2x00queue_flush_queue: Warning - Queue 2 failed to flush

erros em / var / log / syslog requerem a seguinte ação

Execute o seguinte comando

 iwconfig

e obtenha o endereço MAC do Access Point. Eu inseri isso no campo BSSID na tela Configuração de rede na guia wifi

IMAGEM mostrando campos relevantes no Ubuntu 16.04

Espero que isso ajude alguém !!

=============================================== ==========================

Uma hora depois, notei a velocidade da internet caindo para 1 - 3 Mbps novamente ... e notei do / var / log / syslog que aconteceu ao mesmo tempo que um problema do IRQ16.

Então eu segui as recomendações para adicionar "irqpoll" às opções de inicialização.

Para adicionar isso no Ubuntu 16.04 - é necessário Edite o arquivo / etc / default / grub Editar / adicionar uma linha para incluir o seguinte

GRUB_CMDLINE_LINUX_DEFAULT="irqpoll"

Se você já tem valores, basta adicioná-los no final,

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash irqpoll"

Para atualizar o grub cfg - execute o seguinte

sudo update-grub

Você pode verificar se o irqpoll foi adicionado ao seu arquivo cfg fazendo

cat /boot/grub/grub.cfg | grep irqpoll

Você deve conseguir algumas entradas.

Depois de um REBOOT - minha máquina ficou perfeita - 24 horas depois - ainda é o caso!
