Description (Last modified by mrenzmann)

Hi,

I am trying to capture all the traffic from surrounding stations and also what is sent from the card. My current configuration is as follows.

ath0 working as an AP
ath1 is set in monitor mode

While capturing traffic on ath1 by using tcpdump (ethereal) only traffic sent to the card is captured while any data sent from the card through interface ath0 is not captured.

As I recall earlier (old) version of this driver used to capture all kinds of packet. Is there any way to bring back that functionality.

Thanks heaps in advance. Great work
malik

Hi, try the patch attached in #897 which fixes capture of transmitted packets.

Cheers,

Scott.

Hi

I tried your latest version 0.9.3 ( svn trunk) on the cards with the same setup as in the first post, Now the problem is that sometime the card is giving me sent rate of 0. I have fixed the data rate to 54M, but the card gives me data dates of 36, and 48 etc too. Majority of the time the data date is correct ( 54M).

I am capturing it using prism headr format. I will try the radio header later and let you know if the problem is still there.

On a side note does the data rate of the card vandor alot, even if it is fixed, please let me know, how I can fix the rate permenantly. I was using the old drivers for my experiments and convinced myself to use the ng driver as it has removed some of the bugs in monitor mode. Can you also please clarify the status of monitor mode issues.

Thanks Malik
