"update of the packet capture window". What's that?
I started a simple traffic monitoring in wireshark. Nothing fancy.
In the 'Capture Options', the only option you can set is 'Hide capture
info dialog'. If you turn on 'Update list of packets in real time' or
'Automatic scrolling in live capture', packets get dropped. I don't
know if its a libpcap queue that fills up, if it starves the NIC, or
what--but having those turned on greatly reduces the # of packets you'll
capture.
Hm, yeah. I have that turned on. But I don't see this issue
when monitoring with bcm43xx hardware.
I had read about it on a libpcap forum a while ago (it wasn't an ipw2x00
issue that was being discussed); I never looked into the root cause of
it since I figured it was 'just the way it was'.
If you turn it off, does the # of packets captured improve w/ the ipw2200?
