Hi... Can you help me please?
How to set up my wifi card to monitor mode, to will be able to capture packets from only one wireless network? For example I need capture packets from network - essid "KOZ4" channel 8. When I used shift + L in Kismet on this network, so my card captured packets from other networks too and packets from network KOZ4 were mostly malformed and previous segment of packets were lost. I have Intel 3945 wifi card with ipw3945 driver and Ubuntu 6.10 32b.

I hope that you will understand my problem and sorry for my English

First of all I hope your not trying to break into someones wlan and that your only experimenting on your own.

I have not tried to capture packets with kismet that much i can however recommend another program that i think is way more competent. Program is "airodump" its a part of "aircrack", with airodump you can capture packets on specifik channel and on specifik accesspoint even between specifik client/AP. You control it via cli wich can be a bit more difficult but once you get the hang of it its great.
Heres a link http://www.aircrack-ng.org/ .

Good Luck!
