WiFi Guard doesn't see some or any devices on my network

Sometimes WiFi Guard may be unable to detect some or all devices connected to your network. There can be a few reasons for that:

  • Those devices are in sleep mode. Wake, activate, or turn them on, and try rescanning the network again. Sometimes it takes a couple of scan rounds to detect everything.
  • Your router is using a so-called wireless client isolation or session isolation, which means that the devices cannot see each other over the network. There should be a setting in the router's web-interface to turn this feature on and off.
  • An incorrect network adapter was chosen in WiFi Guard settings. Make sure it is an active adapter connected to WiFi or cable.
  • A firewall is running on your computer and preventing WiFi Guard from accessing the network. Try turning the firewall off.
