Wifi lento, temporariamente consertado redefinindo a conexão

3

Eu tenho uma nova instalação do Ubuntu em um desktop com este cartão Wi-Fi Gigabyte conectado a ele. O driver padrão do ubuntu parece estar funcionando, o que é bom porque não consegui encontrar drivers Linux Gigabyte proprietários. No entanto, a velocidade é tremendamente aleatória e, muitas vezes, abaixa para o intervalo de ~ 0,2mbps até que eu desabilite e habilite o wifi.

Eu encontrei muitas respostas semelhantes a isso, mas como o leque de problemas de Wi-Fi é grande, tenho evitado respostas que envolvem, por exemplo, a remoção de módulos e etc. O que posso começar a investigar para encontrar a raiz desse problema? questão específica para a minha máquina / compilação e, em seguida, resolvê-lo?

Eu possuo e uso com sucesso dois dispositivos sem fio da Intel. Eu aprimorei algumas técnicas em vários anos e milhares de posts no fórum.

Primeiro, verifique as configurações no roteador. WPA2-AES é preferido; não qualquer modo misto WPA e WPA2 e certamente não TKIP. Segundo, se o seu roteador for capaz de atingir N velocidades, você poderá ter melhor conectividade com uma largura de canal de 20 MHz na banda de 2,4 GHz em vez de 20/40 MHz automática, embora seja provável que afete a velocidade de N. Eu também tenho melhor sorte com um canal fixo, 1, 6 ou 11, em vez de seleção automática de canais. Além disso, certifique-se de que o roteador não esteja configurado para usar apenas N velocidades; auto B, G e N são preferidos.

Noto que o seu SSID tem o nome "Speedy Remember Harambe". Eu trabalhei recentemente em um caso em que a conectividade foi muito melhorada, notavelmente, removendo espaços no nome. Eu sugiro que você tente renomear a rede para algo como SpeedyRememberHarambe.

Depois de fazer essas alterações, reinicie o roteador.

Em seguida, recomendo que seu domínio regulatório seja definido explicitamente. Verifique o seu:

sudo iw reg get

Se você obtiver 00, essa é uma configuração de tamanho único, talvez ajustada para todos. Encontre o seu aqui: link Defina-o temporariamente:

sudo iw reg set IS

Claro, substitua o código do seu país, se não a Islândia. Definir permanentemente:

gksudo gedit /etc/default/crda

Use nano ou kate ou leafpad se você não tiver o editor de texto gedit.

Altere a última linha para ler:

REGDOMAIN=IS

Revise cuidadosamente, salve e feche o editor de texto.

Em seguida, defini o IPv6 como Ignore no Network Manager: link Este exemplo é para ethernet, mas você quer wireless.

Reinicie o computador e deixe-nos ouvir seu relatório.
