[RESOLVIDO]Notebook desconecta do wifi após hibernar/suspender
« Online: 21 de Março de 2017, 14:07 »
Olá!

Uso um Dell inspiron 14 5458, intel core i3, com ubuntu 14.04. Toda vez que ele suspende ou hiberna o wifi desconecta. Para voltar a reconectar, só reiniciando-o. Como tenho duas redes (uma rebate a outra), é só conectar na outra. Mas eu estou cansado desse problema e gostaria de uma solução.

Eu achei estes posts relacionados, mas não me senti seguro para prosseguir:

O que vocês me recomendam?
Obrigado.

Step 1: Create a new script in the systemd system-sleep folder.

sudo gedit  /lib/systemd/system-sleep/reset_network.sh

Step 2: Copy and paste the following into the newly created script.

#!/bin/bash
if [ $1 = post ] && [ $2 = suspend ]
then service network-manager restart
fi

Step 3: Save e exit.

Step 4: Make the script executable.

sudo chmod +x /lib/systemd/system-sleep/reset_network.sh

reboot and test suspend!

Sua máquina está atualizada?
Qual é o adaptador wireless dela, o adaptador Dell/Broadcomm, ou o Intel iwlagn?
Pesquise antes de perguntar, sua dúvida pode já ter sido respondida.

Como vejo essas informações?
Esse problema acontece desde que o notebook chegou em casa, há quase um ano.

Verificar atualizações:

sudo apt-get update && sudo apt-get dist-upgrade

Verificar o adaptador wireless: voce deve ter escolhido o modelo do adaptador quando comprou a máquina. Se não lembra de ter escolhido, ou se não comprou na própria Dell, provavelmente está com o adaptador Dell mesmo. De qq forma, vc pode confirmar com o comando abaixo.

sudo lshw -C network

Cole o resultado aqui que a gente te ajuda a analisar.

voce deve ter escolhido o modelo do adaptador quando comprou a máquina.

Comprei na própria Dell, mas não tinha opção de escolha, ou escolhi sem saber.

Re:Notebook desconecta do wifi após hibernar/suspender
« Resposta #5 Online: 21 de Março de 2017, 15:05 »
Veja se isso resolve seu problema.

No meu caso, tive problema com conexão de internet após hibernação do Ubuntu 14.04. A conexão de rede simplesmente não retornava, ou seja, a rede permanecia em estado de sono. No meu caso, inseri uma linha de comando dentro do arquivo /etc/pm/sleep.d/10_grub-common (Que na verdade é um script). Para editar este arquivo:

1) Abra o terminal e vá até a pasta acima: cd /etc/pm/sleep.d
2) Digite sudo gedit 10_grub_common
3) Veja os comandos dentro deste script:

#!/bin/sh
# Tell grub that resume was successful
case "$1" in thaw)
[ -s /boot/grub/grubenv ] || rm -f /boot/grub/grubenv
mkdir -p /boot/grub
grub-editenv /boot/grub/grubenv unset recordfail

# Nova linha de comando inserida (24/07/2014)
nmcli nm sleep false
;;
esac

4) Salve o arquivo. Hiberne (Ou reinicie a máquina). Em seguida certifique se o dispositivo de rede volta automaticamente. O comando acima acorda a interface de rede, digamos assim. Pra mim funcionou bem! abs

Não resolveu:

Veja se isso resolve seu problema.

No meu caso, tive problema com conexão de internet após hibernação do Ubuntu 14.04. A conexão de rede simplesmente não retornava, ou seja, a rede permanecia em estado de sono. No meu caso, inseri uma linha de comando dentro do arquivo /etc/pm/sleep.d/10_grub-common (Que na verdade é um script). Para editar este arquivo:

1) Abra o terminal e vá até a pasta acima: cd /etc/pm/sleep.d
2) Digite sudo gedit 10_grub_common
3) Veja os comandos dentro deste script:

#!/bin/sh
# Tell grub that resume was successful
case "$1" in thaw)
[ -s /boot/grub/grubenv ] || rm -f /boot/grub/grubenv
mkdir -p /boot/grub
grub-editenv /boot/grub/grubenv unset recordfail

# Nova linha de comando inserida (24/07/2014)
nmcli nm sleep false
;;
esac

4) Salve o arquivo. Hiberne (Ou reinicie a máquina). Em seguida certifique se o dispositivo de rede volta automaticamente. O comando acima acorda a interface de rede, digamos assim. Pra mim funcionou bem! abs


RESOLVEU!!!
Tive esse problema aqui no meu ubuntu 16.04 e segui esse tutorial aqui que e "batata" para ajudar  ;  )

https://igtek.tk/index.php/2016/05/11/fix-ubuntu-16-04-no-wireless-connection-after-suspend/

Step 1: Create a new script in the systemd system-sleep folder.

sudo gedit  /lib/systemd/system-sleep/reset_network.sh

Step 2: Copy and paste the following into the newly created script.

#!/bin/bash
if [ $1 = post ] && [ $2 = suspend ]
then service network-manager restart
fi

Step 3: Save e exit.

Step 4: Make the script executable.

sudo chmod +x /lib/systemd/system-sleep/reset_network.sh

reboot and test suspend!

Logo que voltei da hibernação o notebook já estava conectado, então acho resolveu e foi a segunda opção, do platão.

Muito obrigado, zekkerj e platão.
