Eu recentemente instalei o Ubuntu no meu laptop Dell Inspiron 1545.

Eu posso me conectar à Internet via Ethernet, mas sem fio não funciona. O prompt para colocar na senha WiFi aparece, mas quando eu coloque a senha, ele simplesmente diz conectar e o prompt para a senha volta! O prompt voltará a cada dois ou três minutos, mas a mesma coisa acontece.

Eu tentei instalar drivers usando drivers sem fio do Windows, mas não consigo descobrir. Minha placa sem fio é um atheros ar928x. Esta é a minha primeira vez usando o Ubuntu.

Aqui está a saída dos comandos que recebi para executar:

I recently installed Ubuntu onto my Dell Inspiron 1545 laptop.

I can connect to the Internet via Ethernet, but wireless won't work. The prompt to put in the wifi password pops up, but when I put in the password, it simply says connecting and the prompt for the password comes back up! The prompt will come back up every two or three minutes, but the same thing happens.

I've tried to install drivers using Windows Wireless Drivers, but I can't seem to figure it out. My wireless card is an Atheros AR928X. This is my first time using Ubuntu.

Here is the output of the commands I've been asked to run:

Eu tive esse mesmo problema com um cartão sem fio Realtek RTL818EEE e Ubuntu 13.04. A solução rápida foi apenas colocar no IP do meu roteador sem fio, depois alterá-lo da AES para TKIP-AES. Isso manteve os outros sistemas no meu feliz sem fio, e repentinamente o Ubuntu assumiu a senha e me conectou com uma velocidade de conexão de 72MB relatada.

Eu não poderia fazer muito mais desde que eu estava sendo executado do DVD, certificando-se de que ele funcione antes de instalar. Eu tinha visto sugestões de fazer Ndiswrapper e depois reiniciar - não vai ajudar no DVD.

Espero que isso ajude a qualquer outra pessoa. Provavelmente tarde demais para ajudar a pessoa original a postar, mas talvez ajude outra pessoa. Se você não puder fazer TKIP-AES, tente ir de AES para apenas TKIP. Que foi sugerido em outro fórum também.

 

I had this same issue with a RealTek RTL8188EEE wireless card and Ubuntu 13.04. The quick solution was to just put in the IP of my Wireless Router, then change it from AES to TKIP-AES. This kept the other systems on my wireless happy, and suddenly Ubuntu took the password and connected me with a reported 72Mb/s connection speed.

I couldn't do too much more since I was running from the DVD, making sure it works before I install. I had seen suggestions of doing NDISWrapper and then rebooting - not gonna help with the DVD.

Hope this helps anyone else looking. Probably too late to help the original person posting, but maybe it will help someone else. If you can't do TKIP-AES, try going from AES to just TKIP. That was suggested in another forum as well.

Por favor copie e cole os comandos para precisão uma linha de cada vez:

  script1.sh2   

Também seria melhor definir a criptografia no roteador para apenas WPA2 se você tiver essa opção entrando em 192.168.0.1 ou algo muito semelhante aos números no seu navegador, tendo uma conexão Ethernet, você pode ter que olhar A documentação para o seu roteador para os números exatos entram.

também tente o canal 1 ou 11 no seu roteador.

Você pode google a documentação para o seu roteador. Por favor, defina suas configurações sem fio no Gerenciador de rede para corresponder às capturas de tela. Configurações sem fio configurações sem fio

Você também deve remover sua conexão no Gerenciador de rede e redefinir seu roteador e reiniciar o computador.

 

Please copy and paste the commands for accuracy one line at a time:

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf  sudo modprobe -rfv ath9k  sudo modprobe -v ath9k 

Also it would be best to set encryption in the router to just wpa2 if you have that option by entering 192.168.0.1 or something very similar to those numbers in your web browser while having an ethernet connection, you may have to look at the documentation for your router for the exact numbers to enter.

Also try channel 1 or 11 in your router.

You can google the documentation for your router. Please set your wireless settings in network manager to match the screenshots.wireless settingswireless settings

You should also remove your connection in network manager and reset your router then reboot your computer.

Certifique-se de ter ferramentas sem fio instaladas via sudo apt-get instalar ferramentas sem fio

Isso fornecerá uma GUI melhor para se conectar a redes sem fio existentes.

Tente pingar qualquer site, computador local ou não, para testar se estiver funcionando. Você pode obter um erro específico, o que pode significar que algumas das configurações estão desligadas.

 

Make sure you have wireless-tools installed via sudo apt-get install wireless-tools

This will provide a better GUI to connect to existing wireless networks.

Try pinging any site, local computer or not, to test if it is working. You may get a specific error, which may mean that some of the settings are off.
