I have got my raspberry pi and I am trying to set up my wifi on my rPi 2 Model B. I am using a Comfast CF-WU755P wireless USB dongle, but it doesn't show in the Raspbian Wifi Config in the GUI. I have read there may be some RealkTek drivers or something that need to be put on the pi, but I don't even know how to put them on the Pi. Do I use a USB or what? It's all too confusing, so please give me an easy step by step answer I can understand.
Anyone know why this is happening, and please don't give me the typical change the interfaces file in network folder and all of that, because trust me, I have tried everything, and nothing is working.
