You would need high speed internet (cable or DSL) and a wireless router in order for the Archos unit to get to the internet. Your manual that you receive with the unit should explain the set up procedure. The Archos unit will also pick up wireless feeds in public areas (Airports, Coffe shops, etc..). Be prepaired that is you contact Archos about this, they do not have the best customer service in the world.
Hope this helps.. Good luck!
