Several unknown computers connected to my wifi network

Solved

Hello,

I suspected my neighbors were stealing my Bbox internet connection, and after doing some research, I downloaded "who's on my wifi". I saw that 3 unknown "devices" are connecting to my wifi (of course, I've identified my connected devices as well, which number 4 including laptops).

So I changed my wifi password, but there are still 2 unknown "devices" connected.
I think I misunderstood this software "who's on my wifi" because it's in English.

Finally, I don't understand much, so I would like to know if the devices I suspect are connected without my knowledge are really unknown (I'll provide the necessary information) and if that's the case, how can I prevent them from connecting to my wifi anymore?

An explanation of "who's on my wifi" would really help me.
Thank you ^^

    Hello

    It's possible that the unknown devices are actually your printer (if it’s WiFi), or your mobile phone, or...

    Here’s a way to secure your Bbox WiFi:
    https://www.panoptinet.com/securiser-ma-connexion/documentation-technique/la-configuration-du-wi-fi-bouygues-telecom.html

    At the end of this document, it mentions "MAC address filtering": this filtering is very effective because it only allows the devices you designate to connect to your WiFi, thanks to the MAC address (which has nothing to do with Apple) that is unique to each device that can connect to a network.

    Here’s how to configure your Bbox to apply MAC address filtering:

    Here’s how to find your PC’s MAC address:

      Ok, thanks a lot, I will try all that!

      I have identified the phones I know connected to my Wi-Fi, but I didn't think about the printer, that's true. But it's hard to know since devices are named with numbers and letters or even nothing.

      So do you really have WiFi connections that aren't from your place?

      Hi

      MAC filtering is illusory and doesn't hold up for long against someone who can find the WiFi password for your router

      Changing your WiFi password is the right thing to do using WPA2 encryption and also changing the access password to your router's configuration

      In the "unknown" section, also think about a possible TV decoder

      Finally, this software does not only list WiFi connections but all the devices present on your local network (including Ethernet connections)

      a good wifi key with uppercase letters, lowercase letters, and numbers

      Alright, thank you very much for your answers,

      and I don't know how to tell if it's my Ethernet cable or my TV decoder.
      But I think that's it, because when I changed the Wi-Fi key, those two "devices" that I thought were unknown stayed connected.
      But there was another unknown device that had connected (not anymore though)
      Well, in any case, I will do all these manipulations when I get back to school to be sure.

      Thank you all!

      Yes, it's showing up like the other Wi-Fi networks, but there is indeed a code to enter, so it's secure.
      Thank you for all your messages.
