In WiFi Guard settings, the scanning options can be set to scan a certain number of devices simultaneously - "Scan this many devices simultaneously". What exactly does that mean and how does it work? I couldn't find anything in the user manual.
Another scanning option on the Advanced tab says it is possible to "Get web-page title from HTTP enabled devices". How do I get such "web-page titles" and where are they shown? Again, no information to be found in the user manual.
Scan this many devices simultaneously option simply refers to the number of devices scanned in parallel.
A higher number will achieve a faster scanning but will use more computer resources, and vice versa. Usually there is no need to adjust this setting unless you have a reason to want WiFi Guard scans finish sooner or use fewer system resources.
Get web-page title from HTTP enabled devices option allows WiFi Guard to capture web-page title from devices that have a web-interface, to provide user with more information about such devices.
When a device is first discovered, WiFi Guard tries to get its name to help the user recognise it. However some devices don't have names assigned to them. In such case, if a device doesn't have a name but has a web-interface, WiFi Guard fetches the web-page title. Usually those titles say something like "Welcome to XXX" or "Login to XXX", so the user may recognise XXX as their device.
