Hello,
Since last night, I have a computer connected to my network (in the list of computers in "Computer," precisely), but I have no idea what this computer is; the only thing I know for sure is that it doesn't belong to me.
The problem is that it is not connected to my box via Ethernet, nor is it connected to my Wi-Fi, which totally perplexes me.
The only things I have are the name of the computer, a MAC address (which allowed me to verify that the computer is not on my Wi-Fi), an IP address, a serial number, and a unique identifier (and two possible addresses among my neighbors)
How can a computer be on my network without being connected to my box? I would like to know before I go knock on their door and complain...
Configuration: Windows 7 / Chrome 24.0.1312.52

It's a shared folder on another PC, so if you can open it in Explorer, you'll know what it's about and what type of files are shared.
Make sure that no computer on your network has an ad-hoc or similar network that is not secured, and on which a neighbor has connected.
A printer, a multimedia hard drive, anything that offers a Wi-Fi network bridge can introduce an external machine onto your network, without it necessarily being hacking.
If you can't find it, you can always try knocking on your neighbors' doors until you find a Corentin, and ask him not to connect anymore.
The simplest solution remains to secure your network and your devices properly.

Mouthon -> An ad-hoc network, what does that mean?
Otherwise, as for connecting to it with an external device, the only thing connected to my Wi-Fi is my PS3 (aside from our computers, of course), and "CORENTIN-PC" was always there even when it was turned off.
I have indeed planned to go knock on my neighbor's door, but as I said, I’m trying to understand first in order to avoid any unfounded accusations.

An ad-hoc network is a direct network created by a machine to which one or more other machines can connect, without going through an access point (your box is thus "bypassed").
What I suggested is to check all the machines in your house to see if any of them has one created.
The ad-hoc network has multiple uses, but one of them is to serve as a 'network bridge', which allows people connected to the ad-hoc network in question to connect to another network to which the machine is connected.
What I suggested then is to check if any of the computers at your place has one created, and if it happens to be the case, then disabling it could solve the issue.
Another method would be to try to connect to all the unsecured networks that your main computer detects until you find one that may be responsible ;)
Have you tried connecting as a guest on Corentin? By simply entering "guest" in the username, if he hasn't secured his file sharing, you'll be able to access it.

For me, it's what I mentioned earlier, it's a shared folder on a computer, either your father's or another one. The fact that you don't have access and probably don't have a user account on that computer means that if you know the ID and password of the administrator account on that computer, you can access the folder. Otherwise, you need to create an account on the other connected PCs to be able to log in with your own ID and password.
The recalcitrant who does not want to connect to your Wi-Fi from the box is probably connected thanks to the magic of another unknown function, available on all current multimedia devices, and if this function is activated on the DNLA box. Turn it off using the appropriate button provided on your Android device and then see if it has any correlation.
not possible, you must have something connected: a TV, a mobile, a Switch, a printer... it’s not necessarily a computer; Windows recognizes each IP address as coming from a computer, but not every IP is a computer.
Windows identifies it as "CORENTIN-PC" in the list of connected computers (just like my "MIYAK-PC" or my father's), which makes me doubt that it is anything other than a computer. It also displayed "CORENTIN-PC" a second time, but this time under media devices.
He doesn't want to open it for me, he's asking for an ID and a password...
But what I still don't understand is how he can be on my network without being connected to my box (see the link of the screen below)
Moreover, when I try to connect to his desktop remotely, it doesn't work.
Oh, and I've never had this computer on my network before last night.
