The HUB can be plugged into a router or modem or set up wirelessly if your router transmits a wifi signal.  It doesn't come with a router and depends on an existing connection to the internet.  You can test it for 30 days and take it back if it's not compatible or you don't like it.  There is, however, a restocking fee of $35 if you return it, because it can't be resold as "new."
