Do i need another part to connect to the internet for my motherboard

First of all, every new motherboard can connect to the internet, its just a standard 😛
If you want to check it out anyway, go to your link, 3rd picture, you can see the ethernet port top of the 2 usbs
 
No the motherboard doesnt have wireless on it, but thats actually a pretty rare feature on desktop pc mobos
If you need wifi you can buy an adapter like this http://www.mwave.com.au/product/netgear-wna3100m-n300-wifi-usb-mini-adapter-ab55151
I owned one of these myself, but then I decided to put a 10-meters ethernet cable throughout my hall from my pc to the router
Seriously,you must consider it, I have never had any lag or connection timeouts in games since then
