smalltech there two cheap ways. if the pc are near each other then a cheap 4 port switch will work.
the other is a router.

you want a router that does n now. if you have older cards the n routers will slow down.

How to connect the switch or router? Is my "new connection" setup below correct? (note: the *router belong to the flat owner. I do not want to touch it.)

Now: Internet source from wall (fibre terminal)>modem>*router>Ethernet Cable connect to PC in my room

New connection: Internet source from wall (fibre terminal)>modem>*router>Ethernet Cable connect to [new router]/[new switch]>Ethernet Cable connect to any PC.
