Glasfibre and wifi or utp..

In a couple of weeks i get a glasfiber connection with tripple-play (TV,
Telephone and internet) The standard speed for the internet is 10 mbit.

What would be wiser:
an UTP connection to the comp (ASUS A8N-SLI Deluxe) or wifi?
The wifi connection would be more esthetic, because otherwise i have to put
cable from one side of the room to the other side (including doors 30
meter).
I'm afraid that due to the wifi i can't get everything of the speed, is this
true?
What would you recommend?
And if using wifi, what kind of router?
