The Scanner panel gives you access to the Wi-Fi scanner configuration. The application scanner sweeps through the channels supported by the wireless adapter to collect and analyze packets being sent on the selected channels. It is not recommended that you modify the default 250 ms per channel scan interval. As for the list of channels to be scanned, you may want to modify it if you know that some of the channels supported by the wireless adapter are not used in your WLAN. For example, if your WLAN does not use the 5 GHz band, you may want to turn off all 5 GHz channels; this will shorten the scanning cycle and, therefore, increase the data accuracy. However, please keep in mind that skipping some of the channels may result in the application's inability to detect sources of interference, such as neighboring APs that work on the channels that were skipped. If you uncheck the Use the same interval for all channels box, you will be able to specify individual per-channel intervals. It is recommended that you leave this box checked. You can use the Select channels button for selecting or deselecting all channels, as well as for selecting channels based on the country- or region-specific allowed channel lists (e.g., choosing United States will select channels 1-11 and deselect channels 12-14 in the 2.4 GHz frequency band). The Scanner panel can be used only if you have a compatible adapter for passive surveys.
