Two Network Adapters , one Loses Signal

I use the laptops bulitin NIC to reach the Internet, and then i added a usb wifi adapter to reach my security cameras.

Unfortunately after a few days the Connection to the Internet through the built in NIC is lost.

I have noticed a Solution that if I use a Proxy in the Webbrowser that , the Laptops NIC connection to the Internet returns.

Both Networks run fine.

So I need to ask how i can enter a Proxy from my own personal router to the Webrowser.

If i use the VPN Proxy, the internet slows down too much so i need to enter a Proxy that would be directly to my own router. Therefore no speed limits.

I guess i could create a reserved Ip for my laptop in my router settings and then enter that as my local proxy. But I would prefer a static ip and i dont want to have to enter that each time in the webbrowser network connection.

Open a cmd prompt type ipconfig /all then tracert 194.119.131.66 post both results
