No puedo conectar la notebook a Fibertel via ethernet

[User21]

Tenés DUAL BOOT en esa máquina? Window$ puede estar "administrando" la configuración de energía de esa placa, dejandola "OFF". n_n

[sefsinalas]

WHAT?! nono...no tengo mocosoft en mi pc. Pero igual la bateria no es porque esta al 100%

probaste con pppoeconf? a mi siempre me salva las papas

Las conexiones de cablemodem no usan ese protocolo, son Ehternet lisa y llanas.

Se me ocurre que deberiamos ir al principio y esto es tener a la vista la salida de los comandos en consola/terminal de "lspci", "lsusb" (por las dudas) y "lshw" (sin las comillas) asi tendremos una vision concreta de que cosas de hardware ve, como las ve y que es lo que no ve. Ademas nos dara la informacion necesaria sobre el chip de la interfaces de red en cuestion.

Que dice la configuracion de redes de Network Manager ? Que adaptadores de red esta gestionando ?

[sefsinalas]

Bueno...aqui estan las 3 salidas que me dices:

Como veras en ninguna aparece nada de Ethernet. Estoy un poco embolado porque no entiendo como puede no andar

[guillermolisi]

El BIOS de la notebook tiene opcion para habilitar/deshabilitar el adaptador de red (LAN)(no me refiero a bootear desde la LAN sino a encenderlo/apagarlo).

Por las salidas que mostraste no hay ningun adaptador Ethernet por cable electrica/fisicamente incorporado a la maquina, lo que realmente me parece muy raro considerando es una notebook.

[sefsinalas]

Claro...pero si aparece durante los primeros 2 booteos despues de instalar el S.O.
ya busque en la BIOS pero no encontre nada. A mi tambien me parece rarisimo. Alguna otra idea? Porque de que si funciona como ya dije...pero despues de unas cuantas reiniciadas deja de andar.

[guillermolisi]

Sugiero que inicies la note con un LiveCD/pendrive con 9.10 y en ese modo (sin instalar nada de nada) te fijes que salidas te dan los comandos que corriste.

Si con la version basica de la 9.10 (sin actualizaciones) se ve la placa de red Ethernet, entonces podria ser una cuestion de software. Si el contenido de las salidas de esos comandos, particularmente "lspci" y "lshw" (ya que esta claro que la placa es PCI y no USB), no difiere de lo que obtuviste un par de post antes, entonces diria que el problema esta en el hardware, en la maquina precisamente.

[sefsinalas]

Me parece buena idea...

reinstale kubuntu y esto fue el resultado:

como veran ahora si aparece en ambas salidas la palabra Ethernet...y tengo internet, ahora mismo escribo este post desde internet. Una vez que baje las actualizaciones y reinicie todavia funcionara...pero a la siguiente vez seguramente ya no tendre internet. Buscare mas info pero si alguien sabe algo aviseme por favor.
