Re: Strange Kismet Newcore behavior

Hey Denis,
the tests have been done in two locations. Both with quite a few APs (~5/~30) and the same results at both locations. The APs/Ad-Hoc networks keep popping up like hell. Real APs do have strange characters in the SSIDs. When using an RTLink or Atheros USB card, no problem. No problem with a Atheros based Fonera, too. Just with this TP-Link AP I´m having issues right now. Unfortunately I don´t have any other TP-Link hardware to test with.

Cheers,
Nils

I get this type of behavior using Airodump when using certain model TPLink
Even within the brand, different models produce varying results.
The other reason may possibly be transmitter receiver saturation -
what distance ?
Try another AP ?

Hi guys,
I´m looking into a strange Kismet behavior.

The wireless IDS I´m running is based on:
Kismet Newcore Server 2011-03-R2
Kismet Newcore Drones 2010-07-R1 running on  Atheros Fonera Drones
This setup is working great!

Then I´ve tried to add a drone based on TP-Link´s TL-WR1043ND access point
with a AR71xx 802.11ng chipset and running OpenWrt Backfire 10.03.1-RC6
The wireless chipset driver is  ath9k/mac80211
It didn´t matter which version of the Kismet-drone I´ve tried, I ended up
with Kismet filling up the logs with strange APs popping up. See log output
below!
Next to Kismet 2011-03-R2 I´ve compiled the lastest svn version of
Kismet-Drone for OpenWrt Backfire, both including full support for
libnl/netlink mac80211.
But still......
These BSSIDs look weird. They are changing and popping up every second. I´d
have expected ~30 APs around me but not hundreds of them in a few minutes,
all with hidden SSID. But it looks more like a general wireless driver issue
as even Aircrack/Airodump-ng shows some strange APs.  Both either Kismet or
Aircrack show broken SSIDs with strange characters in them, too.
