This looked intriguing; a sub-$100 Windows 10 PC.  I received it yesterday, hooked it up, booted it up, went through the initial setup, connected to my wireless network, and got to the desktop with no issues (as you would expect).  Surfed the internet, tested the video playback, all looked good!  Left it for the night at 8:45 PM.Next morning I moved the mouse to wake it up, signed in and opened Internet Explorer to do some more web surfing.  It said I was not connected to any network.  Check the "adapter settings" and the only adapter was a Bluetooth adapter.  Decided to reboot it for grins expecting the WLAN to show up after the reboot - nope. Shut it down, unplugged the power, let it sit for about 10 minutes, booted it back up and still no WLAN adapter either in Device Manager or Network & Sharing Center.I decided to check the event viewer and sure enough, less than an hour after I had left it the night before, there were WLAN adapter malfunction entries until finally, less than another hour later, the WLAN adapter had been removed.  So now it's not even a decent paperweight - back to Amazon it goes.
