As of 2.6.17, a driver for the Broadcom bcm43xx wireless chipset has been included in the kernel. Older kernels can sometimes be made to work, check out resources available here While this driver natively supports monitor mode, it requires patching before packet injection can be done. After testing aireplay-ng with the patches, please contribute to the forum thread by reporting any successes or failures there.
This patch may not apply directly and may require that you modify the bcm43xx_main.c (located in $linux/wireless/net/drivers/bcm43xx/ manually.
Because the bcm43xx injection scheme is rather, ahem, unconventional, it is necessary to apply one of the following patches to aireplay-ng, depending on the version you are using. The patch detects a loaded bcm43xx driver, uses “bcm43xx way” to inject packets and automatically changes the packets per second rate if needed instead of crashing aireplay-ng.
The bcm43xx has been verified to produce all attacks. However, there a few known problems.
There is a problem in the bcm43xx driver when injecting packets using DMA access. I'll try to compile the mod without DMA and see what happens asap. I'll also make another patch soon that waits till the send buffer is empty before resuming after an error occured. Now it just waits a second before resuming at a lower rate.
Same problem as above, there is a problem with injection and DMA access.
ASSERTION FAILED (!ring→suspended) at: drivers/net/wireless/bcm43xx/bcm43xx_dma.c:71:request_slot(). Again, a problem with DMA. Aireplay tries to write a packet, the driver wants a free DMA slot for that and can't because the DMA slots were all taken (the driver blocks all dma requests then).
