We have just moved into a flat under a house, and the WIFI is shared with the main house upstairs.
We have a couple of Windows laptops, and a Macbook Air, and also a PLEX server.
I'd like to keep our PC's private from other users on the LAN. How do I best go about this? Start by changing the Windows Workgroup name to something obscure, but what else? I have access to the router settings.
Thanks in advance.
