can u completely not send any traffic or is this a random drop. If
random there could be interference causing replay counter mismatch.
This may force AP to drop the packet, the ap may de authenticate
client if it sees continuous stream of such packets in a short
interval and force client to drop existing sessions like ftp.
Please try changing the channel. If the client and AP are both A
capable please try using the A band as there are more non overlapping
channels and u may be able to find a channel with low interference.

I keep seeing my wlan0 interface go down.. I suspected a faulty wifi

Ive tried using WEP and WPA. Currently using WPA.
Here are the logs Im seeing..

Given the errors seen what would be the best debug to use??
wlandebug or tcpdump ??
I went ahead and enabled since my logs are complaining about
association and
authentication..
yeaguy# wlandebug -i wlan0 auth+assoc
net.wlan.0.debug: 0x0 => 0xc00000<assoc,auth>
yeaguy#
Any tips would be appreciated.. I have an end user continually
complaining
of disconects over FTP..
Thanks,

Hi Mubeesh,
It seems to be a random drop.. FTP will be humming along and then
wlan0 will go down..
I have the router set for channel 11...
i do not have these types of drops with other wifi capable devices..
ex. WIN laptop, Playstaion 3... etc...

Also yesterday, I lost complete connectivity to the router while my
WIN PC was connected and browsing just fine..
I had to bounce the interface and reset the default gateway and my
connection restored.
I did:
/etc/rc.d/netif restart && /etc/rc.d/routing restart
Thanks,
Justin
What version FreeBSD are you using? The only workaround I know is kill
wpa_supplicant and run again- been happening to me for ages. But 8.1 it
_finally_ sorted it out :)
