The right click on your adapter (so probably ethernet) then properties, then Internet protocol version 4.
On the popup window click Use the following ip adress, then also use the followind dns server
Enter an ip adress just pick somthing that would not be already taken, for example if devices have ips of 192.168.1.1-192.168.1.12 the pick something like 192.168.1.20
Netmask should probably be 255.255.255.0
Gateway should be your router
And dns can be 188.8.131.52 and/or 184.108.40.206
after that click apply, and it should work
