Wireshark-users: Re: [Wireshark-users] wireless lan packet

Hello,

I was wondering.  I'm capturing packets from our server VLAN and I'm seeing a lot of duplicate packets.  Is there a way to filter out those duplicate packets by IP ID?

Thx.

I should have made it more clear.  Packetyzer and Wireshark are 
installed on the same PC.  Registry points to "c:\program files\winpcap" 
for winpcap.  I've also confirmed that no packet.dll exists under the 
network chemistry's directory.  I am using packet.dll version 4.0.0.901 
and Wireshark Version 0.99.6a (SVN Rev 22276).

Weird...I was going to write "Packetyzer let's me capture with my Cisco 
CB20A card.  Wireshark does not.  It throws up an error message....."

so I ran Wireshark to get the error message (what I got earlier).  But 
now, it works (user data, not control data).  Very odd.  I'll see if I 
can reproduce the error message that I got earlier.
