2Tb first edition retailer PlayStation 4

Product Name: 2Tb first edition retailer PlayStation 4
It works, but for some reason it won't stay retailer connected to a controller. It has to be connected at all times. It is the first PlayStation 4, but we bout a adjustable memory thing that will allow us to add a computer hard drive to it. The hard drive still works like new. Since we don't know how to fix the wireless thing. I was posting this as is and for parts unless you know how to fix it or can work with it. Comes with power cord and HDMI cord only.
