Software-specific FAQ:

Is my network card supported?

Airscanner™ Mobile Sniffer supports all known wireless networking cards and integrated WiFi

such as the Toshiba e740 series -- and even the flawed IPAQ 5450 series to some extent (use the

fix below to correct the reported problems in the 5450 hardware). They key is to select the

correct adapter at program start-up. Please check with your device manufacturer to find out

what the appropriate driver name for your card is. Note certain footnotes and exceptions to this

as described below.

Does your product work with the IPAQ 5450 series?

Latest Update: HP has partially fixed their 5450 wireless hardware problem in a later ROM

release (1.11.19 ROM). If you download this fixed version of the ROM or later from HP, you

will be able to view packets non-promiscuously by choosing the correct adapter (vnetusba1),

without having to perform the registry hack listed below. However, you will need to reset your

device for each new capture session. Hopefully HP will continue to work on their bug in the

5450 series drivers. Thanks to Benjamin Bolton for this update.

Yes, it works with the 5450 series. Part of the problem is mistakes from your device

manufacturer.

In the meantime, Sgyee, a reviewer for PDAJunkie.NET, offers this hack on how

to get the sniffer working on the IPAQ 5450:

1) Load the ROM Update

2) Load the WLAN update over the ROM update

3) Perform the VNETMINI1 registry patch (see below)

4) Load AirScanner Mobile Sniffer

5) Turn off promiscuous mode.

How to perform the VNETMINI1 registry patch:

To fix HP’s error in order to enable your WLAN card so programs like Airscanner Mobile

Sniffer can see it, use a CE registry editor to go to

\HKLM\Comm\vnetmini\Linkage

Then delete the Multi-String Value Route and enter a new Multi-String Value Route with the

value of vnetmini1.
