O Atheros Wi-Fi não funciona no ubuntu 17.10 para o Acer Aspire

Question

Após o comando

sudo lspci | grep Network

Eu tenho:

03:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev31)

Há boas notícias, ao acessar a Internet sem fio, a Internet funciona por 3 segundos e tudo

Answer 1

Por favor, veja:

wlp3s0: disabling HT/VHT due to WEP/TKIP use

Por favor, verifique as configurações no roteador. WPA2-AES é preferido; não qualquer modo misto WPA e WPA2 e certamente não TKIP. Segundo, se o seu roteador for capaz de atingir N velocidades, você poderá ter melhor conectividade com uma largura de canal de 20 MHz na banda de 2,4 GHz em vez de 20/40 MHz automática, embora seja provável que afete a velocidade de N. Eu também tenho melhor sorte com um canal fixo, 1, 6 ou 11, em vez de seleção automática de canais. Além disso, certifique-se de que o roteador não esteja configurado para usar apenas N velocidades; auto B, G e N são preferidos. Depois de fazer essas alterações, reinicie o roteador.

Em seguida, recomendo que seu domínio regulatório seja definido explicitamente. Verifique o seu:

sudo iw reg get

Se você obtiver 00, essa é uma configuração de tamanho único, talvez ajustada para todos. Encontre o seu aqui: link Defina-o temporariamente:

sudo iw reg set IS

Claro, substitua o código do seu país, se não a Islândia. Definir permanentemente:

sudo nano /etc/default/crda

Altere a última linha para ler:

REGDOMAIN=IS

Revise cuidadosamente, salve e feche o editor de texto.

Alguma melhoria?

EDIT : Eu não posso, em sã consciência, sugerir que alguém proteja suas redes sem fio apenas com WEP, pois é bastante inseguro: link

In August 2001, Scott Fluhrer, Itsik Mantin, and Adi Shamir published a cryptanalysis of WEP that exploits the way the RC4 ciphers and IV are used in WEP, resulting in a passive attack that can recover the RC4 key after eavesdropping on the network. Depending on the amount of network traffic, and thus the number of packets available for inspection, a successful key recovery could take as little as one minute.

Sugiro que você desative a economia de energia no Network Manager. Do terminal:

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*

Reinicie o Network Manager:

sudo service network-manager restart

Por fim, vamos ter certeza de que você tem o firmware mais recente. do terminal:

sudo dpkg -s linux-firmware | grep Version

Se a sua versão for anterior a 1.169.2, faça:

cd /tmp
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.169.2_all.deb
sudo dpkg -i linux*.deb

Reinicie. Alguma melhoria?
