Realtek RTL8723BE. Red inalambrica se cierra al alejarse del modem/ruter [SOLUCIONADO]

Post by Dickfree » Wed Dec 13, 2017 8:59 am

Instalé Sylvia en este equipo:

Code: Select all

Network:   Card-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
           driver: r8169 v: 2.3LK-NAPI port: 4000 bus-ID: 02:00.0 chip-ID: 10ec:8168
           IF: eno1 state: down mac: <filter>
           Card-2: Realtek RTL8723BE PCIe Wireless Network Adapter
           driver: rtl8723be port: 3000 bus-ID: 03:00.0 chip-ID: 10ec:b723
IF: wlo1 state: up mac: <filter>
System:    Host: lely-HP-Laptop-14-bs0xx Kernel: 4.10.0-42-generic x86_64 (64 bit gcc: 5.4.0)
           Desktop: Cinnamon 3.6.6 (Gtk 3.18.9-1ubuntu3.3) dm: lightdm Distro: Linux Mint 18.3 Sylvia
Machine:   System: HP (portable) product: HP Laptop 14-bs0xx v: Type1ProductConfigId Chassis: type: 10
           Mobo: HP model: 831E v: 17.36 Bios: Insyde v: F.21 date: 07/24/201
CPU:       Dual core Intel Core i5-7200U (-HT-MCP-) cache: 3072 KB
           flags: (lm nx sse sse2 sse3 sse4_1 sse4_2 ssse3 vmx) bmips: 10848
clock speed: min/max: 400/3100 MHz 1: 691 MHz 2: 697 MHz 3: 699 MHz 4: 699 MHzHH
Cuando la notebook se aleja del modem o el router la conexion se cierra porque disminuye la intensidad de la señal.
la configuracion de las preferencias son Automatico (DHCP)
Uso este sistema operativo en mi PC de escritorio sin ninguna dificultad.
Este mismo equipo tiene Windows 10 y no tiene problemas con la conexión.
Hay alguna solución o debo cambiar de distro?

Hola Dickfree. Bienvend@ al foro. :D

Deberías esperar la participación de los que si entienden de estas cosas que posiblemente necesiten mas información , como el contenido del archivo de texto (whireless-info) que se genera en tu directorio de usuario al introducir el siguiente código en una terminal (Ctrl+Alt+T).
    • Code: Select all

      wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info
Asegúrate de estar conectado a la red por otros medios (cable) cuando lo hagas, edita el archivo y copia su contenido aquí usando la opción Code como se indica en este post.

Parece ser que las tarjetitas estas vienen con dos antenas mientras que los laptops de HP solo tienen una (y mal posicionada) . Por lo que puedo entender se trata de un problema con los controladores que está pendiente de solución, pero en tu caso, con el kernel 4.10 podrías tratar de cambiar la antena a ver que pasa (no es infrecuente que el bluetooth deje de funcionar al cambiar de antena).

Puedes probar
  • 1)Editando el contenido de /etc/modprobe.d/rtl8723be.conf (si no existe créalo) con
    • Code: Select all

      gksudo xed /etc/modprobe.d/rtl8723be.conf
      comprueba los siguiente parámetros

      Code: Select all

      options rtl8723be fwlps=0
      options rtl8723be ant_sel=2
    si no existen añáde las dos lineas (copia y pega) y guarda el archivo.

    2)Prueba la nueva configuración reiniciando y/o asegurate que se recarga el módulo con
    • Code: Select all

      modprobe -r rtl8723be
      modprobe -v rtl8723be
Puedes ver la intensidad de la señal con dicha seleccion de antena, si es menor que la que tenías cambia la antena (volviendo al punto 1) con options rtl8723be ant_sel=1 y recargando el módulo (2). Suerte. :wink:

Editado: código incompleto subsanado,

Perdón faltaba un trozo de código, precisamente el que ejecuta ese script y genera el archivo wireles-info.txt cuyo contenido es el que tienes que devolver. Mea culpa :oops:

Code: Select all

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info

SOLUCIONADO.
Gracias a Jopeta inefable colaborador. La solucion estuvo cuando cambie a la antena 1.
Los porcentajes de conectividad cambiaron de una 24% a 100%.
Todo muy simple gracias a tu sabiduría.
Un abrazo y FELICES FIESTAS!

PD: Por favor, edita tu primer post (el que abre el hilo) haciendo clic en el icono del lápiz a la derecha y añade [Solucionado] a ese título. Gracias. :wink:
