Habilitar Wifi Broadcom en Ubuntu 9.10 Karmic Koala

Existe un problema en la instalación de Ubuntu 9.10 en la instalación de los drivers de tu tarjeta inalámbrica WiFi, que impide que sea reconocida de inmediato. Aquí veremos la sencilla solución, para las tarjetas del tipo Broadcom.

Supuestamente (no lo he probado), si realizas una instalación completa de Ubuntu 9.10, deberías estar conectado a Internet por cable y de esta forma te detectaría tu tarjeta inalámbrica sin problemas. Si no lo hiciste de esa forma, y tu tarjeta inalámbrica no es reconocida, continúa leyendo.

Primero, si quieres saber que tarjeta tiene tu computador, simplemente abre una consola y escribe:
mauricio@digitalconcept:$ lspci -nn | grep Broadcom

01:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)


Si tu tarjeta es del tipo Broadcom, y no es reconocida, este procedimiento te puede servir:

* Sistema -> (Administración) -> Gestor de Paquetes Synaptics. Introducir la clave que proporcionaste durante la instalación.
* Click en Configuración -> Repositorios desde el menú superior.
* En la pestaña “Otro Software” seleccionar las 2 opciones que aparecen. Click en “Cerrar”.
* Click en “Recargar”.
* Una vez que se actualice la lista de paquetes, seleccionar el paquete “bcmwl-kernel-source” de la lista. Con el botón derecho haces click en “Marcar para instalar”.
* Aparecerá una ventana indicando que el paquete tiene otras dependencias. Simplemente, presionamos “Marcar”. Luego, presionamos el botón “Aplicar” para que tomen efecto los cambios.
* Una vez finalizado el proceso de actualización, reiniciar el equipo. Listo! debería estar funcionando tu tarjeta inalámbrica y ya no es necesario el cable.

I have been surfing online more than three hours
today, yet I never found any interesting article like
yours. It's pretty worth enough for me. In my view, if all website owners and bloggers made good content as you did, the net will be a lot more useful than ever before.
