I keep seeing my wlan0 interface go down..  I suspected a faulty wifi 
router.. i changed that out..

Ive tried using WEP and WPA.  Currently using WPA.

Here are the logs Im seeing..

Dec 16 07:47:57 yeaguy wpa_supplicant[9492]: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
Dec 16 07:47:57 yeaguy kernel: wlan0: link state changed to DOWN

Dec 16 07:48:20 yeaguy kernel: wlan0: link state changed to UP

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,
