Omnipeek will run with a NDIS 3 or higher compatible Ethernet, Fast Ethernet, or Gigabit promiscuous mode network adapter. Promiscuous mode is the ability to have Omnipeek take over the driver and put it into a mode that will allow it to passively capture all packets on an Ethernet wire, regardless of the address to which they are being sent/received.
For wireless packet capture, Omnipeek requires the installation of a custom driver corresponding to the supported wireless network adapter. Savvius has tested adapters based on Atheros and Ralink chipsets for wireless captures. Other wireless cards may work with this version to the same degree that they worked in prior versions; however, these cards would not be supported.
