4.1.3 Configuring PC Ethernet port for WIF.exe
WIF.exe can be configured to operate over the PC Ethernet port. There are a couple of things which must be done
first, in order to allow proper Ethernet operation…
WinPcap
WinPcap is a networking package which MUST be installed on your PC in order for WIF.exe to communicate to the
WISM+ over Ethernet. You would have been warned at install time if WinPcap didn’t exist on your PC. This
package is used by programs like “WireShark” to monitor network traffic (just one example). You must install this (if
you don’t have it) before attempting to use WIF.exe over the Ethernet port. It allows WIF.exe to capture and transmit
network packets bypassing the windows protocol stack.
To install WinPcap on your PC, go to “http://www.winpcap.org”. Click on the option on the left of the screen called
“Get WinPcap”. Under the “WinPcap 4.1.1 download” section, click on the link…
Download the installer and launch it on your PC. Follow the installation instructions so that it will automatically start up
at boot time.
Stopping services which interfere with network traffic
At Laird, we use Symantec virus protection and network traffic monitoring. Part of its job is to look for potentially
harmful network traffic which might be hacking into your computer. The WIF to WISM+ communications look
potentially harmful to these types of services, and the services will interfere and capture the network traffic thus
keeping WIF.exe from communicating with WISM+ over the Ethernet interface.
Click…StartControl Panel and double-click on the “Administrative Tools” icon. Next, double-click on the “Services”
icon. Once the “Services” window is open, scroll down to the virus protection services. The following screen shot is an
example of the Symantec services which are running (if you use Symantec virus protection). Over to the right, under
the “Status” column, you can see the services which have been started. Right click on the service, and click “Stop” on
all the Symantec services which indicate “Started”. Your PC will be vulnerable to attack, but you will only be
connected to the WISM+ Dev Kit. When you are finished using WIF.exe, turn the services back on to connect back to
your network, or simply re-boot.

WinPcap must be installed on your PC.
Any PC service which traps out of the ordinary network traffic must be halted.
