This Linux kernel module tracks stations on a 802.11 monitor interface and collects various statistics. This might be useful to assess link qualities, find out which stations are in range or are interfering, etc.

BUILD

To compile against your currently installed kernel, just type:

make

if you want to compile against some other kernel, use:

make KERNELPATH=/path/to/kernel

USAGE

Usage:

1. Create monitor device mon0, for example by doing: iw phy phy0 interface add mon0 type monitor flags control ifconfig mon0 up

2. insert the kernel module: insmod wifi-statistics.ko

3. activate the monitor device: echo 1 > /sys/kernel/debug/wifi_statistics/mon0/active

4. read the statistics: cat /sys/kernel/debug/wifi_statistics/mon0/stats

Optional:

echo "read" > /sys/kernel/debug/wifi_statistics/mon0/mode or echo "reset" > /sys/kernel/debug/wifi_statistics/mon0/mode

The reset mode is similar to the read mode, deletes all stations from the internal database when reading. In read mode, the internal database is not modified. (reset mode is default)
