The Preferences Menu gives access to additional features, including showing or hiding specific columns in the information chart, changing graph views, and customizing speed test settings.
Show Best SSID for Scan Results - Allows devices that are on the same network (such as multiple routers or access points) to be combined into one result, displaying the one with the best signal.
Delete networks if not seen after - Removes networks from scanner if they are not seen after the time limit.
Access Point Groups - Groups SSIDs from the same Access Point in the Channels graph for easier viewing. (SSIDs on the same channel coming from the same Access Point do not interfere with each other, instead they take turns. So their signal only needs to be shown once on the graphs.)
Show Signal Value on Graph - Automatically add the signal values (RSSI values) to the time spots on the graphs for each network shown on the graph for “RSSI vs. Time”.
Show Gridlines for Graphs - Add gridlines to the x-axis and y-axis for all graphs.
Show Summary Screen when Closing WiFi Scanner - Turn on/off the pop-up summary screen seen when the app is closed down.
Font Size - Adjusts the Font size of the values in the information chart.
Toggle Columns on/off for the Information Chart. These settings are saved when WiFi Scanner is closed, then reopened.
Show Avg Download Line and Show Avg Upload Line - Turn the dotted averages lines on/off for the Speed Test graph.
Repeat Speed Test - Allows the user to have continuous speed tests running with a wait time between entire test sets.
Run Speed Test automatically - Speed tests run as they move across a network, such as one with multiple Access Points or varying networks.
Custom Server - Test using your own local or Internet hosted speed test server. Please visit http://wifiscanner.com/custom-server.html for instructions on how to setup a custom speed test server on your own network.
Preferences for the “Who’s On My Network?” tab include an IP Address range. By default it will choose the current subnet you are connected to and search all the IPs within that range X.X.X.1 – X.X.X.254.
The default Netmask (255.255.255.0/24) is what most home networks use. It can be changed to shrink or enlarge the IP Range that will be scanned.
