Internet intermitentemente cai em 16.04

Question

Como o título diz, eu continuo tendo que desconectar e reconectar do meu wifi para obter uma conexão com a internet (e ocasionalmente reiniciar meu computador). O wi-fi se comporta bem quando estou no Windows, então eu sei que isso não é um problema específico de wifi.

Eu tentei 1. Alterar a versão do meu kernel 2. Desligar o gerenciamento de energia 3. Desativar o IPv6 4. Tornar a resolução de endereços IPv6 somente local de link. Nenhum desses funcionou.

Aqui está uma saída do dmesg, porque eu acho que tem alguma informação relevante.

Answer 1

eu corrijo o problema seguindo esta pergunta respondida :

1. Verifique seus detalhes da rede sudo lshw -class network
2. Obtenha o valor logical name , no meu caso wlp1s0
3. Dê a permissão sudo chmod 755 /etc/pm/config.d/
4. Abra ou crie a configuração e adicione SUSPEND_MODULES="wlp1s0" (substitua wlp1s0 pelo seu próprio logical name )
5. Em seguida, execute echo "options wlp1s0 fwlps=N" | sudo tee /etc/modprobe.d/wlp1s0.conf , Finalmente reinicie seu sistema.

Eu também tento executar sudo service network-manager restart , mas eles dizem que é apenas uma solução temporária.
