Caleb Hearon pointed me at the "Network stalls every 30 seconds" thread
from back in June which contains the suggestion of doing:
echo >/sys/kernel/debug/ieee80211/phy0/ath9k/disable_ani 1
This fixes the immediate packet loss problem for me. There still seem to be
some issues with the first few packets of a large ping getting lost (during
ARP it would seem), and DHCP takes a long time to complete when ath9k is
initially brought up.
Is anyone working on a fix for the ANI problem?
