ICS stopped working to eithernet adapters

Thanks guys in advance..
Let me start by describing my normal setup. I currently for the last two months use a (sprint) phone connected via USB to an Asus vivobook win 10 edition. I use Pdanet (full paid) to make the internet connection. Then using ICS in adapter section of networking I share this connection to the realtek family contoller ethernet adapter. From there I share to my Linksys smartfi ea8300 router. This has worked great for a little more than a month. I turned off all updating (that I could think of) to prevent changes... then a week ago stopped working. Internet to the laptop via usb still works like a champ but now only get limited or no internet to the router. Now this is where it gets fun....
I have 2 other computers(win 7, and win 8.1) and another ausus router plus various cat5's.. Ive tried all three computers both routers and different cables...always same outcome which is internet works on the computer but can not be shared... if it is it is limited and a static Ip is in my Ipv4 but once I set to obtain Ip automatically I lose it all. also Ive used two separate phones to test even resetting one back to factory default. I get the same pre generated static Ip address in the ethernet adapter ipv4 section from both phones... this all leads me to believe my isp(sprint) has changed something... I hope there is help...

No sir, that is what fills in automatically when I first startICS to be shared from Pdanet (or usb tether without pdanet) to my ethernet adapter. that is auto filled into my Ipv4 properties on my ethernet adapter. I have not contacted Sprint as I feel most likely will not get a lot of , honest, feedback. Just wanted to see if anyone was having similar or knew of this issue first.

I'm not exactly sure what you mean or quite how to do it.

Here is a tutorial on how to change DNS servers:

And here is Google DNS servers:

The Tutorial also has the DNS servers for Google on the page if you scroll down.

Thank you... I'm to read up and work through these.. I'll check back in shortly....
