Problema no Xubuntu 14.04 com TP-Link WN822Nv4

Question

Eu obtive recentemente o adaptador TP-Link WN822Nv4 (EU) porque o meu adaptador de bordo não parece funcionar muito bem (baixa intensidade de sinal, meu telefone recebe 10x a velocidade), mas não posso para a vida de mim descobrir como fazer isso funcionar. Eu tentei procurar no site por coisas semelhantes (como isso e isto , o segundo reportou algum tipo de erro), mas nenhum deles parece funcionar. Meu laptop é um HP Pavilion G6-2002SM, se for importante.

Saída de lsusb (o dispositivo 004 é o adaptador que eu acho):

Não estou muito familiarizado com a solução de problemas no Linux, por isso não consigo descobrir como resolver o problema. Algum conselho?

    

Answer 1

Eu não percebi a versão do kernel, para atualizar para 4.4 você pode

sudo apt-get install linux-generic-lts-xenial

Precisamos nos livrar de uma das instalações do dkms, pois não tenho certeza se o Pilot6 atualizou seu PPA para a Trusty

sudo dkms remove rtl8192eu/4.3.1.1.11320.20140505~trusty1 --all

sudo dkms remove 8192cu/1.10 --all

Reinicie

Então podemos instalar o git e o build-essential

sudo apt-get install git build-essential

Em seguida, podemos clonar o código github de Mange

git clone https://github.com/Mange/rtl8192eu-linux-driver.git

Em seguida, use dkms para adicioná-lo sudo dkms add ./rtl8192eu-linux-driver

Em seguida, instale

sudo dkms install -m rtl8192eu -v 1.0

Reinicie

O código da Mange suportará seu dispositivo por causa de um commit feito há 6 meses
