Setting Up and Scanning Networks
1. Access the “File” menu and select “Preferences” add a checkmark next to “Log Data”. Click OK.
2. Select the wireless interface of your choice from the drop down list (most computers have only one).
3. Click the “Play” button (resembes a VCR) to start the test.
4. Sort the networks by “Signal” - lower numbers first (like golf, a lower number is better!
5. Ensure the “2.4 Ghz Channels” graph is showing! The channels with the most wifi networks represent the frequency bands with the most interference from other networks.
6. Click your network’s name to highlight it.
7. Leave the program to run for about 15 minutes and take a screenshot of the report. This will save the screenshot as an image in your “Pictures” file folder. Include the image in a reply to the most recent ticket email you received from email@example.com as an attachment.
