I'm currently setting up a let, with five student rooms on two floors. Is it desirable to have Ethernet cabling to each room? Thanks
Absolutely! And, as the other poster has alluded, perhaps leave a cable or two in the room. If you're gonna cable to the room, you'll prolly want a central switch close to the router so that you can actually distribute stuff. However there + and - to consider. The router will have 4 Ethernet ports. You've got 5 rooms; one Ethernet port per room maximises throughput potential per room. Five cables from a switch, the switch connected to a single Ethernet port requires a switch that minimises contention when all 5 students are at it streaming.
So there's a bit of thinking to do. You'll still find students who'll only be interested in wireless and might whinge when the Hub's woreless won't reachthrough a couple of floors and walls. If you are going to be a dream landlord, you could install Powerline adapters on each floor to broadcast wireless.
If you want to go the whole hog, I would put two Ethernet connections in each room and one wireless Access Point per floor, all wired back to a 16 port switch next to the router. You could also possibly turn off the wiresless on the router.
