<p class=MsoNormal>I’ve ran into a very odd situation with WinPCap 4.1.2.
I have a several quad core HP computers running a WinPCap based application
that sends a broadcast UDP message at 10hz. For some reason on these HP
machines, instead of the broadcast (192.168.x.255) coming out of the NIC at
10hz, the traffic only seems to be at 1-3hz (this is displayed on our embedded
system.) If I run Wireshark on the local HP PC though, I clearly see a
packet every 100 ms. However, if I run Wireshark on another PC connected
to the same network, it confirms the 1-3 hz issue. Here’s the really
strange thing. If I plug in a USB drive, or a USB network adapter (even
though I’m not using it), the broadcast starts working normally (10 hz).
Unplug the USB device, and it drops back down. I ran a test application
that uses basic Winsock (the Delphi Indy components to be exact), and it always
seems to work fine.<o:p></o:p></p>

<p class=MsoNormal>Any suggestions are greatly appreciated.<o:p></o:p></p>
