Who Is On My Wifi – Blocking
Who’s On My Wifi currently offers 2 supported solutions for blocking unknown devices on a network.
#1. Router Based Blocking – Blocking that is done at the router to disable network access for certain devices. Who’s On My Wifi offers this through the Simple Secure Router. The Simple Secure Router offers a stable blocking technique through the use of IPTables on an OpenWRT firmware.
#2. Mac Filter Blocking – Any device that is detected by a Who’s On My WiFi detection agent will show the Mac Address. This Mac Address can be added to the Wireless Mac Filter of your current router for a consistent, stable blocking effect. Look into the details of your current wireless router to see how to do this.
Deprecated – No Longer Supported – Software Based Blocking – A jamming technique done through the Windows software and WinPcap to disrupt a device’s network connectivity. Support for this option was removed on October 2015, and has been removed from all future versions of the software.
Simple Secure Router
Blocking in our router edition provides a consistent, stable blocking effect by using packet filtering on the router to filter any network traffic specifically targeted to go to the device being blocked. In this case, the intruder is still on the wireless, but unable to receive any packets. This is very similar to the technology used in a router MAC Filter.
Blocking in the Simple Secure Router is done using an IPTables filter to remove traffic targeted from reaching the intended receiver.
Your current router may provide blocking through a Mac Filter in several different ways. Please refer to your manufacturer provided information to see how they are implementing their filtering.
Windows Software based blocking worked as a network jammer to disrupt the network connection of devices that were detected. This had several problems, most notably that the computer detecting devices had to be on consistently to also act as the management piece. Also, although the blocking effect worked well when it was first released, it became less effective over time, and finally was pulled as a feature from the Windows software.
