 +If your device ID is NOT listed here, it means it is not supported by aircrack-ng at this time.

 +**IMPORTANT**
  
-Also, if the PCI ID of your card is **14e4:​4315** (BCM4312 with a LP "Low Power" ​PHY, commonly found on laptops), you need to install the development version of the driver, since it is unsupported by the stable versions - you will get a "UNSUPPORTED PHY" ​message in dmesg if you try to use it anyway. More information is provided underway.+Some chips are covered by both the "b43" ​and "​wl"​ driver. If you have such device, you have to make sure you **blacklist** ​the "​wl" ​driver ​before ​you utilize b43, otherwise they will collide and your card will stop functioning altogether, let alone hope for injection. The "wl" ​driver does not support aircrack-ng.

-If you have a card with the 14e4:4315 PCI ID, then you need to install the compat-wireless package, since today'​s stable versions of the drivers do not support this card at all. In fact, the b43 driver is constantly being improved and using the development version of it can yield very positive results for all its users. ​ More on this particular card [[http://​wireless.kernel.org/​en/​users/​Drivers/​b43#​fw-b43-lp|here]].+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'​s stable versions of the drivers do not support this card at all.
