Are you perchance looking at the Digital Fence or are you sure these devices are on your network?

@Pixie if these are not your devices. Could you block with Fingbox?
I think @Pooh @Pixie may not have a Fingbox - am I correct?
Thus, the best bet is to change your WiFi password to get these devices off...

Wasn't sure myself, @VioletChepil...

@Pixie - I've just given this title an update - so we can get more responses too - about how these devices may enter your network and what you can do - if you do not have a Fingbox for example! 

Pixie

O ok so a fingbox adds a security thing to the wifi ????

Pixie

Yes I get it ok thank you , I will look into the fingbox 👌

@Pixie yes if you get the Fingbox you can block devices too!

Rather than rely solely on Fing, you could interrogate your router. 1. Check Wi-fi security is enabled. 2. Ensure your network is protected by a firewall. 3. Check the DHCP table which should provide a list of devices actually connected via your router. 4. Cross check unknown devices against your Fing scan then, if required, block them via fingbox or you may be able to do the from your router.
if you are still uncertain about some devices you can check ip addresses & MAC addresses to verify the individual identity, this information should also be available in your router DHCP table and most networked devices have a label showing the MAC address.
