Subject:Kismet stops recording data (and working) after 5-10 min of use
Date:03:41:35 28/03/2006

The problem I have is that Kismet after 2-10ish minutes of running will stop recording data. The elapsd time is moving, the Madwif ch is hopping around but the packets stop and I can no longer see any new data. When this happens it's like the wifi card is turned off. If I shutdown kismet and start up airodump it will no longer see anything either. So to fix this problem I turn the card off (ifconfig ath1 down) and then back on (ifconfig ath1 up) and then everything is working just find again... till I run kismet for 2-10ish minutes. I have 3+ gig's of space where the data is being stored. Here is what the screen shows after I exit Kismet:
