> Pretty sure that the Kismet opkg package provided in the OpenWRT repositories is not compiled to allow mac80211 VAP creation support. To get mac80211 support I had to compile OpenWRT myself with a newer Kismet version. Guessing that the wireless chipset in the Nanostation M is using mac80211? You only need mac80211 if you are using a newer wireless driver, eg. ath9k.

> As far as the error message, I have no idea sorry. Dragorn would know a lot more about that stuff! As he said, when connecting to a Kismet drone ensure the following criteria are met:
> Firewall - allow traffic through from the Kismet drone. I just turn it off for testing (/etc/init.d/firewall stop)(/etc/init.d/firewall disable)
> Routing - check drone to server connection (I use ping to check)
> Kismet configs - make sure allowed connections in kismet_drone.conf are defined and kismet.conf has drone settings.
> A good way to troubleshoot is to install all the kismet packages (kismet drone, server and client) on OpenWRT and check it is running properly. Note: in this scenario use the drone to collect traffic and forward to the local kismet server on OpenWRT. The kismet.conf file should have drone source as on the local interface.

Hi stomponthis, I've same problem. I've got a TL-WRT1043ND Access Point and I use OpenWrt Backfire 10.03 with kismet-drone - 2009-06-R1-2.
Did you resolve your problem ? I think my problem is in the configuration of ncsource. My ncsource configuration is "ncsource=mon.wlan0:name=mon.wlan0,type=mac80211,forcevap=false,channel=5,hop=fa
and the /etc/config/wireless is

config wifi-device radio0
option type mac80211
option channel 5
option macaddr 00:23:cd:xx:xx:xx
option hwmode 11ng
option htmode HT20
list ht_capab SHORT-GI-40
list ht_capab DSSS_CCK-40
#option disabled 1

config wifi-iface
option device radio0
option network lan
option mode ap
option ssid Openwrt
option encryption none

The kismet_drone run well but i can't see any packet that it captures. The connection between kismet_drone and kismet server is ok. Please give an advise to resolve my problem !
Thank you very much and sorry about my bad english {":...:"}
