Hello,

I would like to monitor the traffic coming from the internet towards the wifi interface of my Linksys WRT54G.
Indeed, I just want to be alerted when there is a new packet for the wireless interface.
So far I have been using tcpdump, grabbing all the packets with destination address belonging to the wifi address range, but I've noticed that this type of approach bring down the speed performances of my connection.

So my question is: is there any lighter version of tcpdump (or a completely different method) in order to monitor the packets?

Thank you,
Mike
