Thanks for reaching out.
A few questions: what devices are you referring to, is it indicated? Are you using a private or public Wi-Fi network Also, what app are you using in detecting the devices?
Have you tried changing your network credential so that you can limit the devices that will connect to your network.
Keep us posted.
