You put switch thingy in there, connect all ports to switch thingy. You connect modem LAN port to any room port (so it connects to switch thingy), and connect modem to WAN via VDSL in room where VDSL available. Dumbed down enough for you?
Alter, kauf dir ein Switch, steck alles dort ein, pack dein Modem dort hin wo du das Internet bekommst (VDSL: Telefonsteckdose, Kabel: Coax), verbinde den LAN port von deinem Modem und voilà jeder Raum hat Internet.

Sorry I'm not a youtuber 😅
It has it's dedicated place, and is my emergency backpack with everything to survive for a few days. It's simply connected via a sowed in keystone jack. It uses an embedded RPi powered by PoE (via said keystone jack) and auto syncs everything. It mostly only syncs PDF/A that I can use to view on a netbook, in case society collapses (instructions and manuals). Backpack has a small solar array and a 40mAh battery pack. Emergency equipment, knifes, axe, rope, fire kit and all of that. It's also the backpack I take on trips and hikes, to see its endurance. It's not meant as a backup your pictures kit, for that I have the four physical locations which are all in different parts of the country.
I think you know that I and everyone else knows that.
Wait till you learn about Wireguard.
Sure, but why not webUI vs VDI?
3-2-1-1-0 and you have 99.9999% covered. I replicate all backups between four physical locations, doesn't get more overkill than this. For personal use I even have a backpack with external HDD in it, that syncs the most important data every day.
Why do they need VDI to manage files? A simple web UI not enough?
Over what distance? What bandwidth?
Funny idea but I see no point in it?
No. In all cases all devices have maximum speed of your network equipment and themselves. I think what you meant to ask if a switch would reduce the bandwidth available to the devices, which is also a no. Both PC’s using the internet at the same time will reduce the bandwidth, but not 50:50. A normal unconfigured router will give 100% of the bandwidth to each connection, meaning, if PC A is downloading a 1GB file that takes 10’ to download, the internet for all other devices for the next 10’ would appear to be very slow, till that download is finished. A more advanced router, would reduce the bandwidth of PC A to like 70% so that 30% can be used by PC B. In any case, the network equipment you use, as long as it is faster or the same speed as your internet connection, and not connected by dozens of switches, will not slow down your internet. Multiple clients do. I have a network of over 250 clients at home, so there are rules in place to guarantee the bandwidth needed for certain devices (like TV’s for streaming) where as other devices (like phones or tablets) are less prioritized.
