Glad to hear you are happy... I've used ASUS motherboards and video cards for many years to build PC's from scratch and they are a great company!

Yes - you would need the wireless router if you want to go unplugged - if you don't mind a cord, you could just go right into any CAT5 plug into the laptop as well. But the freedom you have with wireless is quite nice and truly compliments the laptop mobility as well.

Good luck!
