B43 packet injection

Question

I have bcm4311 which is supported. Looked over here here and here and I only see 2.6.26 patches, and I have 2.6.27 kernel version. Will 2.6.26 patch work or will I mess something up in the process?
My guess it then that this:
cd /usr/src/wireless-testing
sudo wget http://patches.aircrack-ng.org/b43-injection-2.6.26-wl.patch
sudo wget http://patches.aircrack-ng.org/mac80211_2.6.26-wl_frag.patch
sudo patch -p1 < b43-injection-2.6.26-wl.patch
sudo patch -p1 < mac80211_2.6.26-wl_frag.patch
sudo make net/mac80211/mac80211.ko drivers/net/wireless/b43/b43.ko
drivers/net/wireless/b43legacy/b43legacy.ko
sudo -s
make modules_install
is all that needs to be done to make packet injection work or is there anything else I need to do?
And lastly - no, I'm not trying to break into my neighbours or anyone elses network, don't really have any need for such actions. I just want to try it on my own AP to learn more..
thank you

Answer 1

for successful injection, AP you're trying to crack has to have at least one client connected to it. and after that client makes some bandwidth, you 'steal and replicate' one of the packages it made, and with aireplay send it over and over... about 40 000 packages is enough
just follow this steps and it should work.
the thing I overlooked is when you start  airmon-ng start wlan0 <channel> it made another interface mon0 which you then need to use, but i think that's not the problem in your case
