A "device timeout" means that an outgoing packet could not be transmitted during a period of 5 seconds. Assuming the driver works correctly, what you're seeing could simply be a matter of heavy contention for the medium. How many other wifi networks are "active" around you when the timeout occurs? Perhaps monitor traffic on your channel (from another box with a wireless interface in monitor mode on the same channel) continously, and check if bursts of traffic from other networks coincide with the athn device giving up.

If so, can you figure out which conditions trigger them? I use this device daily (have two of them), and have some problems with it. Frequent device timeouts as you said, already changed the router, wifi channel, and still the problem. Sometimes programs takes some time to connect, like when I'm browsing the web and open irc, it takes some time to connect with the server. Usually timeouts happens when I do a new connection, like I never had a timeout when only watching a video on youtube, it happens like when I open a new site. It has been difficult to me to figure out what causes this error, and try to reproduce it, it looks totally random, some days I get a lot of timeouts, others I get no one. -- Regards Henrique Lengler

I'm surprised it works for you at all on 5.6. It might actually crash your machine quite easily because of bugs in the driver. And scanning is rather broken with this device in 5.6 (won't see more than 8 APs). Support for this device was improved a lot for 5.7. See the changelog at http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/dev/usb/if_athn_usb.c There are still some issues, though. Some people are seeing frequent device timeouts which I can't reproduce. And hostap mode seems to be broken. If you have time to do some tests (with -current), I'd be interested to know if hostap works. To test, set it up for hostap mode, try to assoiate to it, assign IPs, and ping across. Does the device send beacons in hostap mode? Beacons should be visible from another computer with a wireless interface in monitor mode on the same channel, and tcpdump -y IEEE802_11_RADIO -v Do you see frequent or occasional device timeouts when using the device normally? If so, can you figure out which conditions trigger them?
