Description Lev A. Serebryakov freebsd_committer 2012-02-02 21:30:11 UTC
  
  Sometimes ath0 gives tiemout when transmitting to 802.11g client.
  The higher is speed the higher is tiemouts frequency.
  When environment is noisy, speed is low and timeouts is rare. When environment is clean, speed is high (up to 2.5MiB/s) but timeouts are frequent.
  Here is output of `dmesg' when reset debug is enabled.
