I'm building a new PC for my friend and the motherboard I'm about to order is in this build below:

But the thing is he cannot 100% use an ethernet cable to get internet for a personal reason so he is forced to use wireless connection but the motherboard I'm looking at buying doesn't have a wireless internet card and I don't know what to do. Should I get a different motherboard that is compatible with my PC's components and has a wireless card or just buy a wireless card, also I was looking at this wireless internet card by ASUS: http://www.asus.com/us/Networking/PCEAC68/
And I have NO idea how it works and if it will work, please look at that and tell me if that's what I should buy for the best internet for gaming, will that allow my friend use his wifi since he's NOT using ethernet and his router is downstairs, so how do we set this up? Please answer as fast as possible because I must order this PC before the cyber monday sales end which is at 12:00pm, thank you so much.
