Is the Samsung Galaxy Core Prime S82OL capable of wifi tethering, if so, how?
As @Avinash had commented, WiFi Tethering is available on all phones, including mine, which is also a Samsung Galaxy Core Prime (but has a different Model Number).

Were you able to at least connect to your hotspot, by your PC, even without a Network Connection (Internet Access)?
If so, then you would have to enable your "Mobile Data" or "Data Connection" to be able to connect to the internet.
