Currently, DSL in, one computer and printer wired to the wireless router, and the rest of the place is wireless. Separate accounts on the machines.
It will change, hopefully soon, with hard wire connections to some of the rooms, and a wireless access point at the other end of the house, it's got a very weak signal. That will also give us coverage in the back yard.
The goal is to have two switches, one in the basement to handle the wiring I run to the first floor, and another up on the second floor to handle any wiring needs up there, with the two connected.
