You will need to explain yourself better.
What memory? [part numbers, not descriptions, please]
What WiFi/BT solution?
What version of Windows are you using? [for example, Windows 10 Pro 1809]
What drivers are you trying to install?
What is going wrong?
What have you tried to do about it?
I am not seeing any attachments. Please use the Image button (button that looks like picture of mountains with sun overhead) on the button bar to upload your images and include them in a response.
Why are you trying to get WiFi working if your Broadband Router is connected directly to your PC?
Under normal circumstances, having an wired connection does not preclude the ability to have a wireless connection as well.
I go back to my original questions. I can't help you if you do not provide me with information (part numbers, especially) about the motherboard you are using, the processor you are using, the wireless card you are using, etc.
I answered that. No, you don't need to remove the wired connection to be able to use the WiFi. But, if you have Ethernet connection to your broadband router, why would you want to also use WiFi for this connection?
