Então, isso significa que o driver foi instalado com sucesso? Mas o iwconfig não dá nada para wlan0 novamente. Ajude-me, por favor, evite voltar ao Windows ...

    

Answer 1

Você instalou o driver rtl8192cu corretamente, mas nenhuma interface sem fio foi criada porque o rtl8192cu está incorreto para o seu dispositivo. Por favor, obtenha uma conexão ethernet com fio temporária e faça:

sudo apt-get install git
git clone https://github.com/purchae/rtl8188eu.git
cd rtl8188eu
make
sudo make install
sudo modprobe -r rtl8192cu
sudo modprobe 8188eu

Quando uma versão posterior do kernel é instalada pelo Update Manager, após a reinicialização requerida, recompile:

cd rtl8188eu
make clean
make
sudo make install
sudo modprobe 8188eu

    

Answer 2

Eu tenho o mesmo D-Link DWA-125 rev.D1, mas

lsusb

imprime

...
Bus 001 Device 005: ID 2001:3310 D-Link Corp. 
...

(preste atenção no ID)

E para que isso funcione, eu mudo o arquivo rtl8188eu/os_dep/usb_intf.c

-       {USB_DEVICE(0x2001, 0x330F)}, /* DLink DWA-125 REV D1 */

para:

+       {USB_DEVICE(0x2001, 0x3310)}, /* DLink DWA-125 REV D1 */

salve

sudo make
sudo make install
sudo modprobe -r 8188eu
sudo modprobe 8188eu

e agora o driver funciona para mim:)

    

Answer 3

O maior obrigado a você. Finalmente, o driver está instalado. A única coisa é que o dongle não funciona corretamente: depois de 7 a 10 segundos de download - nada ou nada fazendo na internet, o ícone na bandeja mostra "sem sinal", o ping é ilimitado.

Apenas por caso eu mencionei que, se eu começar a baixar algo realmente grande, minha boa internet existe, desde que o processo de download seja longo. O que eu fiz errado? Btw, no Windows funciona perfeitamente.
