What versions of OmniPeek 5.1 support the new Advanced Voice & Video features?

These features are included with OmniPeek Enterprise 5.1.

Can I add the new Advanced Voice & Video features to my copy of OmniPeek Workgroup Pro?

No, but you can upgrade your software to the new version of OmniPeek Enterprise 5.1. Just email us: sales@wildpackets.com or call us at 925-937-3200.

What 10GbE adapters are supported in OmniPeek 5.1?

The list of supported adapters can be found at this location on our web site:

What 802.11n adapters are supported in OmniPeek 5.1?

OmniPeek 5.1 now supports both Marvell and Atheros chipsets. Drivers for both of these chipsets ship with OmniPeek 5.1, The current list of supported adapters can be found on our website at:

There seems to be some differences between the way 802.11n data is displayed by the Marvell and Atheros drivers. How do you explain this?

The Marvell driver is developed by that company and the custom Atheros driver is developed by WildPackets. Since we do not control the code in the Marvell driver, these differences are to be expected. We expect that when the 802.11n specification is finally ratified, all the manufacturers will endeavor to make their products completely consistent with the draft. WildPackets, as a member of the Wi-Fi Alliance, is in the forefront of 802.11n technology and OmniPeek has been designated product of choice for 802.11n analysis.

When I configure a capture with my Buffalo card, it reports a speed of 1Mbps instead of 54Mbps in the Capture Options. Why?

This is because Omni 5.1 is reporting the actual speed of the adapter’s connection, not its maximum data rate. This is an issue that will be addressed by Marvell, as OmniPeek cannot be adjusted to change this behavior.

Can you explain the function of the new AP capture adapters included with OmniPeek 5.1?

These adapters work with managed AP solutions from Cisco, Aruba, and Airtight to allow streaming of wireless data on different channels into a single capture in OmniPeek 5.1. These adapters were designed to work with the existing wireless Access Points and Controllers being deployed in modern wireless networks.

What new decoders are included in OmniPeek 5.1?

OmniPeek 5.1 now includes decoders for NTLM2, SOAP, SSL, as well an enhancements for the decodes of MPEG4, H.264, H.323, H.225, T.37, and T.38

Are you going to release a patch for WildPackets Products in order to make them compatible with the new 2007 Daylight Savings Time changes?

Since all WildPackets products make use of the underlying Operating System for all time computations, no patch will be necessary for our products to operate correctly with the new Daylight Saving Time Change.

I see that OmniPeek supports Intel Centrino wireless adapters. Does this mean that I can use the Centrino adapter in my laptop to capture wireless packets?

Yes, but keep in mind that OmniPeek will only support Centrino adapters that use the 3945 chipset. At the present time, that is the only Centrino chipset that is supported. If you have an older Centrino chipset, you will need to use an adapter that utilizes our custom driver.

My new laptop has a built in wireless adapter that uses the Intel Centrino 3945 chipset. I see that OmniPeek now supports this chipset, but I am having problems getting this to work. What am I doing wrong?

Although many manufacturers are using this Intel Centrino chipset for the built-in WLAN adapters in their laptops, the drivers used may vary both in version and design. Please review the items below which are the WildPackets tested conditions for supporting the Intel 3945 Chipset:

1. Window XP, Service Pack 2. (Centrino 3945 is not yet supported on Vista).
2. Intel driver version 10.5.1.72 or 10.5.1.75
3. Make sure the Intel PROSet Wireless utility is *not* installed. If it is, uninstall it.

My new Vista laptop has a Centrino 3945 wireless adapter, but I cannot capture wireless packets. Why?

This is because the Intel 3945 adapter does not have any ISV Promiscuous Mode capabilities. When Intel updates their driver for this adapter and includes ISV Promiscuous Mode, wireless capture from OmniPeek 5.1 will then be possible. This feature is completely incumbent upon the Intel driver update. There is nothing at present that can be added to OmniPeek to allow this functionality.

I see that OmniPeek now supports Vista operating system from Microsoft. Will OmniPeek work with any edition of Vista?

Although all of our testing was done using the Business Edition of Vista, OmniPeek should install and run fine on the other editions as well, such as Home Basic, Home Premium and Ultimate.

Are there any capture adapters that are not supported using OmniPeek 5.1 on Vista?

Capture from the WAC PCI T1/E1 or GAC DAG-Series adapters are not supported under Windows Vista at the present time.

Will OmniPeek 5.1 run on 64 bit Operating Systems?

OmniPeek will load and run on 64 bit operating systems in 32 bit compatibility mode and supports AMD and Intel x86 processors including the 64 bit capable Pentium and Xeon processors.

Does OmniPeek provide Application Performance measurements?

Yes, OmniPeek has fully integrated the Application Performance Index (Apdex).

Why do the Web Views stop displaying new requests?

The web views currently have a limit to the number of requests it will display; ¼ the expert flow limit. By default, the expert flow limit is set to 10,000, so the web views will only display the first 2500 requests.

Will the Web View allow me to view pages visited by the users on my network?

Yes, the Contents tab of the Web Views will attempt to reassemble web pages from traffic still in the buffer. But since there are a myriad of different implementations, content from a number of sites my not be viewable.

What is the timeline tab and column for in the Web View?

It shows a timeline of the selected request, its duration, its packets, and its phases. With it, you can see the timing and location of packets in a request or requests. This will allow you to determine what request is slowing down a page load.

The timeline column is essentially a mini representation of the timeline tab.
