Good morning,
It is possible that it is the different ports of the same machine (LAN/Wifi/virtual) or the passage of a Wifi connection through a Wifi extender (alteration of the client’s MAC address by the extender).
The router associates the MAC address with a name and by default it uses PC-xxx by incrementing xxx

thanks for the contribution
to complete the answer / solution from @DanielD
These PC-XXX machines can be connected to a VPN using a
or a security application (secure connection, etc.) with the creation of a virtual machine
this can also come from a restart of the router which reloads old devices
go to router management and delete them
Router > Expert mode > Network > Device list > Not connected > open details
Remove device
check if they reappear
Router > Expert mode > Network > Device list > Not connected > open details
- check the data and in particular that of “Last connection” of the machine
Status Not connected / Last connection… / Wake-on LAN…
- and if this corresponds to duplicates or not

Hello
These unknown machines are external devices that constantly search for public WiFi. Possibly neighbors with their devices or Smartphones passing near your home. These devices which are not known to your network in the absence of the WiFi code, as your network is not public, they cannot connect and are listed in the “unconnected device” page in gray. as indicated by PC-177, PC 176 etc.

Good evening,
These connections are not only in unconnected devices.
It enters the network but they only receive IPV6 addresses.
There’s nothing to do, I changed the name, changed the password.
Currently I have 1 which is well connected in my network with an IPV6 the signal is strong, I just have parental control as a means, but the name and MAC Address changes all the time.
So it’s impossible to do anything for the long term.
