Wifi solo funciona conectado con el cargador

xfce

#1

Buenos días, el problema que presento es que a través del teléfono genero Wifi y la computadora solo se conecta cuando se esta conectado al cargador, si no esta conectado al cargador se queda cargando un largo tiempo sin realizar la conexión con éxito. He actualizado el equipo a la última versión. Cabe destacar que soy nuevo en Linux así que desconozco muchas cosas, de antemano disculpen mi ignorancia.

Pon este comando en el terminal o consola, copia el resultado que te ponga y pegalo aqui para que lo veamos:

cat /etc/default/tlp | grep WIFI_PWR_ON_BAT

Saludos.

Vale, vamos a intentar una cosa. Vas a editar ese archivo de configuración para cambiar el ahorro de energía del wifi en batería.

En una terminal:

sudo nano /etc/default/tlp

Pones tu contraseña de admin e intro. Con el teclado vas bajando hasta encontrar la opción que hemos comentado antes de:

WIFI_PWR_ON_BAT=on

y la cambias a:

WIFI_PWR_ON_BAT=off

Ahora, para guardar el cambio, pulsas a la vez las dos teclas CTRL + O (O la letra, no cero el número y el mas no es la tecla, quiere decir como y). Y le das a intro para confirmar el nombre.

Y para salir de la edición, una vez mas a la vez teclas CTRL + X.

Ya solo te queda reiniciar y comprobar si ha habido suerte y ha funcionado.

Gracias, me funcionó a la perfección de verdad gracias.


#7

Algún libro o página para aprender sobre el uso de comando etc. Ya que no se por donde aprender.


#8

No sabría decirte, yo he ido aprendiendo sobre la marcha, trasteando y haciendo cosas. Hay varios cursos interactivos online pero en ingles.

Pero vamos, que si pones en Google “guia comandos linux” o similar te vas a hartar a resultados, como por ejemplo:

Pero como te digo, lo mejor es ir trasteando y cuando te surjan problemas, buscar soluciones en Google e intentar aplicarlas tu mismo.

Vale, mil gracias de verdad. Actualmente presento dos problemas, no se si puedes echarme otra mano.
