Question BCM94311MCG in Monitor Mode


Hey guys, Im new to the Linux scene and I'm just trying to figure out if my WLAN card is able to go into Monitor Mode, because I've read that this doesnt work with many cards.

Heres my sudo lspci -vv output

02:00.0 Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 01)

Heres my iwconfig output

eth1 IEEE 802.11g ESSID:"******"
Mode:Managed Frequency:2.462 GHz
Access Point:00:19:4A:1D:23:EE
Bit Rate=24 Mb/s Tx-Power:32 dBm

Power Management: off
Link Quality:31/100 Signal level:-76 dBm Noise level:-96 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

Does that mean that it can only go into Managed mode ? if not can anyone link me some software to test it out ?

Any help would be greatly appreciated

would take it to monitor mode.

I think most cards support Monitor mode but they do not support packet injection. Moreover, while compiling drivers like the ipwXXXX ones you need to make sure that you enable the monitor and injection mode.

Cool, I'll give it a try. I compiled my drivers using a tutorial, I'll see what I can find out about enabling monitor and injection mode. I'm guessing its done by adding a few more commands in.

Thanks for the help
