All motherboards includes integrated audio ( at least over 90% ) this board does not have integrated wireless. Keep in mind there are different wireless specifications.
You could consider a Z87-Pro which has integrated audio along with integrated dual band wireless ( 2.4Ghz and 5GHz ) 802.11N wireless support with Bluetooth 4.0
If the board is too high on price point you could consider
Z87-Plus or Z87-A which are much lower in price and then go with a ASUS USB-N53 dual band wireless adapter which goes for around 30 dollars so it is pretty reasonable in cost. If you are going to consider heavy browsing or downloading and gaming as well as HD streaming then this is a really solid adapter.
Wow! Thanks for the awesome answer!
