We moved into a new building where a wall plate with coax, RJ11 and RJ45 was installed in every room with wires run from the basement. Verizon provided DSL which was turned on but never connected. When the tech showed up to connect it (I wasn't home) for some reason he plugged the modem into a jack on an upper floor, I assume to position the built-in wireless in the most central location (not that it reaches everywhere it needs to go). However that doesn't do much for the hard-wired jacks throughout the rest of the house. I imagine the right way to set up the network is to put the modem in the basement where the service enters the house and then place wireless routers on each floor allowing for wired or wireless access. I would try that myself but there doesn't seem to be a place to properly connect the modem in the basement.
