Win 7 ADSL plus internet from my phone, chose a primary coection?

I want to stream to Twitch which require minimum 2 mbit/s upload speed which I do get from 3G on my phone, so I coect my phone to my PC through USB to share inteet from phone to PC.

The problem is that this changes my fast (24/1 mbit/s 5 ms) ADSL coection to be used as a secondary coection and the phone is used as the primary coection, so this slows down my inteet and my ping when playing games becomes shitty since 3G has high latency compared to ADSL.

I have successfully used two inteet coections where the ADSL coection was the primary coection when I used a 3G stick instead of my phone.

I don't know why the phone is "overwriting" my main (ADSL) inteet coection, but it does. So how do I make the ADSL my primary inteet coection?

This looks like exaclty what I need, so I tried it but it did NOT work...

How to give preference over one network coection over another?...

Also the network and sharing center is slow as FUCK when I have my phone coected to my PC.
