How do I make reverse tethering work?

I've been trying this for a couple of days and I've to say it's not getting any better. I've tried stuffs from here and here , but unfortunately none helped. So if there is any alternative solution to use internet on my phone from my laptop please do humor me. > Please do not suggest opening a hotspot from my laptop as my hardware doesn't support the hostednetwork capabilities. Note : I'm running lollipop.
