Mine came with a little USB WiFi adapter.  I had no trouble connecting it to the network and getting my new Windows 10 license activated.  I’m very happy with it though there was a learning curve for me.  I have not bought a computer in a long time so I was a little concerned when it didn’t have a DVI port on the back for my old flat panel I was reusing.  It had something resembling an HDMI port but it was slightly different.  It had a huge legacy printer port and when I researched the serial number I found it was a refurbished unit from a business lease.  So I fired off a complaint and very quickly received a very kind reply that explained things.  That HDMI thing is a DisplayPort, which is what they all come with now. 😏  I got back on Amazon and bought a DVI to DisplayPort adapter which came the next day and was totally up and running in ten minutes.  I opened the case and found the inside looked real clean and new so I’m relaxed now.  This is a good deal.  The only reason I didn’t give it five stars was because the keyboard is one of those dime-a-dozen types that we replaced with a good Logitech ergonomic keyboard.
