Question [Q] Using Note 3 as a Wireless Adapter


I have been searching around for a way to enable both Wi-Fi and USB tethering at the same time to use my Note 3 as a wireless adapter. I have wireless in my house but I have yet to purchase a wireless adapter for my new desktop. Is there some way to do this natively on the phone? I have seen in some threads that using an app called PDANet would work, but I saw in the same threads that it is a ~$15 app.
