Broadcom 4354 chipset TX1 does not support Monitor mode

I intend to set TX1 Wifi module Broadcom 4354 chip in Monitor mode so that I can use it as a sniffer on Wifi networks.

I downloaded latest aircrack-ng from github and compiled it.

But I am unable to set Wifi module in monitor mode.

Any idea why ?

Hi vaghelan,

Just check that we don’t support monitor mode. “iw list” will list all modes the chip supported.

Supported interface modes:
* IBSS
* managed
* AP
* P2P-client
* P2P-GO
* P2P-device

Is this a driver issue and by recompiling we can enable “monitor” mode ?
Or is this the chipset limitation ?

Hi vaghelan,

It is due to chipset limitation.
