We got a wireless router.  The whole deal with unplugging the modem and bringing it downstairs to play X-Box was getting annoying.  We have another modem, but for $20.00 more per month to use it, a router pays for itself in 2.5 months.  The idiotic thing is that nothing is really wireless in the house.  The computer is attached to the modem, which is attached to the router.  The router has a ginormous ethernet cable running to the X-Box downstairs.  Silly, but whatever.  We knew when we moved we wanted to go wireless anyway, so it’s one less thing.
