O Realtek RTL8188CE é desconcertado aleatoriamente e possui conexões lentas

Question

Eu sou novo no Ubuntu e estou tendo problemas com a Internet, pois desconecta cerca de 10 a 15 minutos e geralmente é muito lento. Eu percebo que este é um problema muito comum, mas parece que as soluções dependem da placa wireless e do roteador que você usa. Eu corri o wireless_script e aqui está o resultado:

Answer 1

O driver usado pelo seu dispositivo é problemático, mas às vezes, se adicionarmos alguns parâmetros a ele e alterarmos algumas configurações no roteador, poderemos fazê-lo funcionar se não tivermos que compilar um novo driver.

Primeiro, na mudança do seu roteador, 802.11bgn para 802.11bg .

Segundo, altere a criptografia do wep para apenas wpa2 (CCMP) (AES) e não (TKIP) se você tiver essa opção, ela funcionará melhor.

Terceiro, configure seu canal sem fio no roteador para 1 ou 11, salve a configuração do roteador e reinicie-a.

Em quarto lugar, vá para o gerenciador de rede no canto superior direito da tela e clique na guia editar conexões > sem fio e defina o IPV6 para ignorar.

Agora abra o terminal CTRL + ALT + _T e copie e cole o código a seguir, uma linha de cada vez, para precisão:

echo "options rtl8192ce swenc=1 ips=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf
sudo modprobe -rfv rtl8192ce
sudo modprobe -v rtl8192ce

    

Answer 2

Os drivers Realtek (para mim o RTL8188ee) são quebrados do kernel Linux 3.13 (talvez antes) em diante. Parece que os desenvolvedores do kernel tentaram resolver um problema de driver RTLxxxx e como um efeito colateral, eles o quebraram. Então eu acho que você tem que esperar, até que alguém conserte de novo. Uma alternativa será fazer o downgrade para uma versão mais antiga do kernel, como a que foi entregue com o Ubuntu LTS 12.04.

    

Answer 3

Eu instalei o kernel principal do Ubuntu 4.0 no meu Ubuntu de 64 bits 14.04 com ASUS PCE-N15 e as coisas são muito melhores! iwconfig reporta 54 Mb / s agora em vez de 1 Mb / s!
