After Patch my wlan0 disappeared

[CeMPUTER]

Hi everyone,

I patched Backtrack 5 when the you have N updates message appear on my screen and after a reboot my wlan0 device disappeared.

When i execute
lspci -vnn |grep -i net

i get the following response which tells me that my wlan0 hardware is still alive [4e4 : 4727]

01:00.0 Ethernet controller [0200]: Atheros Communications AR8152 v2.0 Fast Ethernet [1969:2062] (rev c1)
02:00.0 Network controller [0280]: Broadcom Corporation Device [14e4:4727] (rev 01)

any ideas? When i found a solution i will share it here...

Edit: hmm i just remember that i run the

iwconfig wlan0 txpower auto

command .. maybe that caused the problem ?

and when i run

/etc/init.d/networking

i see "Failed to bring up wlan0" as last line

edit2:
okay i noticed that i can boot the old version of BT5 from the boot menu and Voila! there is a wlan0 device

here some research..
