A conexão com a Internet cai após 1-2 horas (RTL8821AE wifi drivers)

0

depois de instalar o Ubuntu 16.04 meu novo Laptop (Asus P2520LA) Eu não posso resolver um problema que eu tenho com o meu wlan / internet, então eu ficaria muito grato se você pudesse me ajudar.

O problema é que depois de conectar com sucesso ao meu wlan, depois de algumas horas a internet cai de repente enquanto eu estou apenas navegando em um site ou algo assim. A conexão wlan ao meu roteador parece permanecer intacta, mas a internet desapareceu. (O ícone "conectado" na barra superior não muda, mas um ping não é possível).

Depois disso, uma reconexão wlan não é possível (através do ícone) e a única possibilidade que encontrei para reconectar é reiniciar ou remover e adicionar meu módulo de driver:

sudo modprobe -r rtl8821ae && sudo modprobe rtl8821ae

Em este tópico foi publicado um script que coleta informações relevantes para problemas de wlan, portanto, aqui está a saída do script executado logo após a queda da conexão com a Internet:

########## wireless info END ############

Há outra coisa estranha que notei que pode ser relevante: depois que a Internet caiu, posso me desconectar do wlan por meio do ícone, mas não consigo me reconectar. Mas depois de executar o script de análise, as reconexões funcionam bem.

Eu ficaria muito feliz se você pudesse me ajudar com este problema. Se você precisar de qualquer outra informação, diga-me e eu postarei.

Obrigado!

EDITAR: Depois de mais algumas pesquisas, encontrei alguns posts / artigos que descrevem exatamente o mesmo problema que eu:

Infelizmente, em alguns posts o problema permanece sem solução e em alguns outros, onde as soluções são postadas, as soluções não funcionam para mim, então eu realmente conto com a sua ajuda.

Então, acho que consertei o problema agora. Se o dropout não ocorrer nos próximos dias, marcarei este thread como resolvido.

Eu tentei várias estratégias que foram postadas em sites diferentes. Talvez bastasse instalar novos drivers (- > parágrafo 5), mas vou listar tudo o que fiz, apenas no caso de haver dependências:

1. Ignore o IPv6

(sem sucesso direto)

fonte: link

Clique no Gerenciador de rede - > Clique em "Editar" - > Edite a conexão sem fio - > Clique na guia IPv6 - > Definir o IPv6 para ignorar - > clique em OK - > Reinicie.

2. Edite wifi-resume.service

(sem sucesso direto)

source: wi-fi ainda está dormindo quando retomar

gksudo gedit  /etc/systemd/system/wifi-resume.service

Adicione o seguinte:

[Unit]
Description=Local system resume actions
After=suspend.target

[Service]
Type=oneshot
ExecStart=/bin/systemctl restart network-manager.service

[Install]
WantedBy=suspend.target

feche o editor de texto.

Agora faça:

sudo chmod +x  /etc/systemd/system/wifi-resume.service
sudo systemctl enable wifi-resume.service

reiniciar

3. Configurar driver

(sem sucesso direto)

fonte: 16.04 conexão wi-fi LTS perdida aleatoriamente a cada 5 minutos

  1. Get details of your PCI wireless card by running sudo lshw -class network
  2. Get your card model info according to the product line. For instance, as you can see in the question description it says product: RTL8723BE PCIe Wireless Network Adapter so the model of my card is RTL8723BE
  3. Open or create /etc/pm/config.d/config and add SUSPEND_MODULES="rtl8723be"(replace rtl8723be with your own model number) Then run echo "options rtl8723be fwlps=N" | sudo tee /etc/modprobe.d/rtl8723be.conf and reboot.

Now your system should be able to reconnect automatically after sleep, and wifi connection never got lost once for me after doing this.

4. Instalar outros drivers

(sem sucesso direto)

Fonte: link

Verifique se o seu cartão é um dos seguintes modelos: rtl8192ce, rtl8192se, rtl8192de, rtl8188ee, rtl8192ee, rtl8723ae, rtl8723be e rtl8821ae

lspci | grep Wireless

Então:

sudo apt-get install linux-headers-generic build-essential git 
git clone http://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
sudo modprobe rtl8821ae

Reinicie.

5. Mais uma vez, instale drivers diferentes

(Sucesso!?)

Eu passei por tudo isso depois de atualizar para 16.04 wi fi dropping após 5 minutos e, em seguida, muito lento

Então, esse wi-fi desconectado

Roteador conectado via ethernet.

Terminal aberto

entrou no terminal sudo apt-get install wicd

Em seguida, digitou wicd na pesquisa, arrastou o ícone para a barra lateral e clicou no ícone e seguiu os prompts.

Utilizou o canal 11 usado no roteador

Não teve problemas nas últimas 6 horas e a velocidade aumentou, reiniciei 3 vezes apenas para verificar se a conexão automaticamente parece OK

sudo service network-manager restart

Este comando deve consertá-lo mate (Você deve repeti-lo sempre que sua conexão cair) .Não sou especialista, mas um conselho, se o seu laptop for antigo, tente verificar se o cartão está superaquecendo ou da próxima vez que desconectar Execute o comando, reinicie o roteador e verifique se ele está se conectando, caso isso aconteça é problema do roteador não seu computador / OS.Eu costumava ter esse problema, meu computador não vai se conectar à rede reiniciando o roteador consertou.
