O que é o Generic * disabled

Question

Enquanto usava wifi como hotspot, funcionava bem por algumas horas, mas depois parou. Eu comecei a reiniciar o gerenciador de rede digitando o comando: -

sudo systemctl restart network

disse:

Unit network.service not found

e quando eu digitei o comando: -

sudo lshw -c network

A saída foi esta: -

mayur@mayur-HP-Notebook:~$ sudo lshw -c network

Answer 1

Nós vemos algumas pistas interessantes em lshw :

*-generic DISABLED
       description: Wireless interface
       product: Illegal Vendor ID
       vendor: Illegal Vendor ID
       physical id: 0
       bus info: pci@0000:0d:00.0

E em dmesg :

[16343.485345]  rtl8723be_driver_exit+0x10/0x6be [rtl8723be]
[16378.491054] rtl8723be 0000:0d:00.0: Refused to change power state, currently in D3

O ID do fornecedor ilegal é às vezes observado com peças compradas no exterior que aparentemente são clones baratos. Às vezes também é observado em partes que falharam eletricamente. Em ambos os casos, sugiro que o seu laptop precise de uma placa wireless substituta.
