+ | =====Installing the drivers===== | ||
+ | |||
+ | 2.6.24 kernels and newer don't need any patches applied to the driver itself for monitor mode and packet injection. The only patch that is needed (for fragmentation attack support) is the standard mac80211 frag+ack patch. | ||
+ | |||
+ | |||
+ | **Important note:** If you install or update your b43 driver via [[compat-wireless|compat-wireless]], | ||
+ | sudo update-initramfs -u | ||
+ | |||
+ | If you have a card with the 14e4:4315 PCI ID and a kernel lower than 2.6.33, you need to install the compat-wireless package, since today' | ||

+ | Keep in mind that your distribution might offer its own b43-fwcutter package and scripts intended to obtain and extract the firmware. It is up to you if you're going to do it manually or let your distro do the work. If you have the card with the **14e4: | ||

+ | =====Testing the new module===== | ||
+ | |||
+ | After building and installing the new module, it is best to test that injection is working correctly. | ||
+ | |||
+ | =====Troubleshooting Tips===== | ||
+ | ==== Confirm you are running the new module ==== | ||
+ | |||
+ | First, double check that you are in fact running the new module: | ||
+ | |||
+ | | ||
+ | | ||
+ | |||
+ | It will give you the fully qualified file name. Do "ls -l <fully qualified file name>" | ||
+ | |||
+ | This thread has a number of potential fixes to problems you may encounter: [[http:// | ||
+ | |||
+ | ==== "SET failed on device wlan0: Device or resource busy" when setting monitor mode ==== | ||
+ | |||
+ | This is a known issue with all mac80211 drivers. To avoid this error, make sure you do: | ||

+ | |||
+ | | ||
+ | |||
+ | This way, you can monitor on mon0 while still being associated on wlan0. | ||
