[ubuntu-bo] colocar tarjeta inalambrica en modo monitor

Vie Abr 1 21:45:54 UTC 2011

Tengo ubuntu 10.04 x64 en una laptop hp dv7-4190us con la sgte. tarjeta de
red la cual la instale activandola en Sistema-Administracion-Controladores
de Hardware
These package contains Broadcom 802.11 Linux STA wireless driverfor use with
Broadcom's BCM4311-, BCM4312-, BCM4321-, andBCM4322-based hardware.

raul en hpi7:~$ lspci|grep Bro

02:00.0 Network controller: Broadcom Corporation Device 4727 (rev 01)

el controlador de la tarjeta ya esta instalado y puedo conectarme a redes
wifi. El problema es cuando quiero poner la tarjeta en modo monitor

raul en hpi7:~$ sudo airmon-ng stop eth2

Interface    Chipset        Driver

eth2        Unknown         wl (monitor mode disabled)

raul en hpi7:~$ sudo airmon-ng start eth2

Found 5 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!

PID    Name

como ven, no me crea la interfaz en modo monitor (mon0).

Que puedo hacer?
