So, I bought this 4 year old refurbished PC just to access the Internet at home.  The computer has no native WiFi networking.  Instead, the Sellers throw a 50 cent no-name Chinese USB WiFi networking dongle into the box.  It does NOT WORK to give the PC WiFi connectivity.  Windows 10 refuses to connect through it, and it comes with no software drivers.  Obviously, they did NOT TEST IT with accessing the Internet; it will not.  Windows 10 troubleshooting is no help; it's just a piece of crap part they threw in to claim a "working" PC (if you count no Internet access).  Very shady practice.  You will have to go buy a $25 working WiFi dongle with driver software if you want Internet access; otherwise, it's a door stop.
