Using netANALYZER with WinPCAP / Wireshark packets are dropped

When I do a capture via the WinPCAP interface, or in Wireshark, sometimes Ethernet packets are dropped.

Cause it the WinPCAP capture driver.

Two possible causes:

1. Either the WinPCAP capture buffer (see function PacketSetBuff(LPADAPTER AdapterObject,int dim)) is too small, to handle network load peaks.
2. You PC is has too less performance to handle the amount of capture data.
