Ubuntu Networking :: Monitor Mode On Broadcom 14e4:4315 And 14e4:432* Wireless Cards?

First of all, this tutorial will use NDISWRAPPER, not b43, not wl (Broadcom STA). So, hooray for new method (actually, the only method ). Now, I don't want anyone to get scared because of bad experiences with Ndiswrapper or whatever, it's actually quite easy. I did not come up with any of this info. I'm just putting this guide together from Kacper Szczesniak's info (who came up with this method), WifiDocsDriverbcm43xxFeisty_No-Fluff from the Ubuntu Wiki, and my experience. The Broadcom STA (wl) driver has references to monitor mode in it's code, but does not have that functionality in reality. The Broadcom Windows driver on the other hand does have this capability. So, for monitor mode to work, you will need a patched version of ndiswrapper.

1) Install the Linux kernel headers:

Code:

sudo apt-get install linux-headers-$(uname -r)

2) Install the tools required to compile Ndiswrapper:

Code:

sudo apt-get install checkinstall dh-make fakeroot gcc build-essential

3) Unload current Ndiswrapper module, if running:

Code:

sudo rmmod ndiswrapper

[code]....
