Activate USB network adaptor

I have bought and installed a USB network adaptor which has an aerial for better wi-fi reception. How do I tell the computer to use this one? I tried disabling the on-board adaptor but the computer then tells me no network access because there's no adaptor.

The device manager tells me the new adaptor is installed and working properly. Help?

is it shown when you go into network and sharing centre in the control panel at all?

Yes, it's there

Any red / yellow flags?

Right click and choose properties , screenshot what it's showing.

I have attached a Word doc with two screen shoots. Thank you for your kind assistance - it is much appreciated.

Not quite what I wanted to see....this is my equivalent , from network and sharing , double click on the adapter and then choose properties from that box , I've shown my equivalent here ..

Thanks for your response. I connect through wi-fi
