Hi all

Sorry for the seemingly simple question, but I am totally new to building my own PC and wanted to check something

With the motherboard it says that it has built in wifi and BT module, but the graphics on the manufacturers website show an areal plugged in

So my question is, do I need an areal for the wifi and BT?

Thanks
