Hey guys. Having some troubles with my Ouya Wlan.. (obviously )

So I wanna do a workaround and need some help, because im a Noob at network stuff.

My Computer is connected to the internet by wlan. I wanna create a network tunnel to my ouya with a Lan cable to give my ouya what it needs: Internet.

How can I do that?

btw. I've a Win7 HomePremium pc.

best regards,
