Me and three roommates, all wired connections are 1G ethernet. the two wireless APs are in opposite corners of the house to provied the most coverage. everything is wired because for some reason wifi speeds are crap on all devices at any distance from the APs, even on 5Ghz (no neighbours are using 5Ghz)
Incoming connection is 50/10 VDSL.
raspberry Pi is running raspBMC and is connected to our TV. Ubuntu Server acts as a media server, and anything else we need.
setup spans three floors of our house.
