I had some wireless issues right out of the box with Asus F8Va-B1 laptop. It did not see my Wireless N and would not connect to my G. Contacted Asus and they had me send it in, they keep it for a week and returned it with same issues. I contacted EXcaliberPC and they immediately offered a RMA on unit and a full refund which I applied to the purchase of F8Va-C1. Received PC, works great, one powerful little laptop. EXcaliberPC is an outstanding company to deal with and definitely near the top of my “Approved Vender List”
