After I used 'airodump-ng -write ath0 ath0' ath0 interface was left in 'monitor' mode (which maybe is a bug in airodump itself).

Command 'ifconfig ath0 -monitor' is supposed to clear 'monitor' mode. But it doesn't seem to make any difference.

This is a very serious problem  since after this interface isn't usable until reboot.  It stays in 'monitor' mode (no packets go out or in).

Same is true for ral0 device.
