[Q] Reverse Tethering in Lollipop topic

Hi

I have a Moto G XT1033 with Lollipop 5.0.1, and I wanna to use reverse tethering, but I can't... I tried using Android Reverse Tethering 3.2, it connect with no errors but doesn't use my pc's connection.

Can anybody help me? My mobile connection is very very slow (~ 4 KB/s) and I don't have WiFi :'(

Thanks
