+====== DEPRECATED ======
+**IMPORTANT NOTE**: This page is deprecated, updated documentation can be found [[install_drivers|here]]
 ====== ACX100/ACX111  ======
+//Note: This page is about the older acx100/acx111 drivers. For the new mac80211-based driver, see [[acx1xx]].//
+===== WARNING!!! =====
+**There is legal controversy surrounding the development of this driver, see the wireless [[http://kerneltrap.org/comment/reply/6692|mailing list]] for more information. See [[http://acx100.sourceforge.net/wiki/History#Kernel_inclusion|kernel inclusion section]] for some background information on the previous attempt to include it in the mainline kernel.

+===== Driver Status  =====
+This is a short report about acx driver. See [[http://forum.aircrack-ng.org/index.php?topic=2216.msg12412#msg12412|this thread]] for details.
+There are 3 version of the driver:
+- plain
+- SoftMac
+- mac80211
+The current stable release of the "plain" driver is v0.3.36 (acx-20070101) and it works t works on kernels equal or greater than 2.6.10.
+For kernel 2.6.21-22, a patch is needed: http://acx100.sourceforge.net/wiki/Patch_2.6.22
+The driver does not support WPA.
+The driver can be patched for injection with the instructions below on this page.
+The SoftMac version uses deprecated stack layer, it's not updated anymore.
+The [[acx1xx|mac80211 version]] is still in beta. It requires a kernel equal or greater than 2.6.18 (with mac80211 support). Starting with 2.6.27, it will be integrated in the kernel.
+From kernel 2.6.23 forward, an injection patch is already integrated in the mac80211 stack in the kernel mainline. For fragmentation attack support, an additional patch is required. See the [[mac80211]] page for more details.
+All versions require a non-GPL firmware in /lib/firmware/, you can find it online.

+====== Troubleshooting Tips  ======
+===== FAILED to free any of the many full tx buffers =====
+You get kernel messagess similar to:
+Jul  3 00:44:12 ubuntop kernel: [  736.008000] wlan0: FAILED to free any of the many full tx buffers. Switching to emergency freeing. Please report!
+Jul  3 00:44:12 ubuntop kernel: [  736.008000] wlan0: tx timeout!
+From the author of the driver patch:
+That's a problem with the driver. I saw it several times while writing the acx111 patch. It works like this:
+Every packet you transmit allocates a tx buffer, so it will start filling up the whole buffer space until its freed again and that's the point. It just doesn't get freed in time.
+Once you reached the limit and have eaten up all available buffers, it won't work again until you reload the driver. Its waiting for a TX_COMPLETE message...
+Possible workarounds (don't know for sure right now, just try it):
+    * This happens when you use the unpatched driver, double and trible check that you're infact using a patched driver: look at the buildtime, remove all acx modules, make sure your custom module is in the correct /lib/modules/`uname -r`/ path...
+    * Use aireplay-ng 0.8 or higher, as they incorporate indirect support for acx injection (sending more ack frames)
+    * Change your hardware mac to the fakemac used for "-h"
