I have been using this D-Link DWA-131 Wireless N Nano USB Adapter since the last couple of years until few months back some random abnormalities began SHOWING up.
On bootup in the taskbar corner it shows as device not connected unless I eject it and then reinsert it back to its USB 3.0 port and my mobo detects it. This happens rarely. But that's annoying to have access to the back side of this HUGE cabinet. Have a look at the attached screenshots and the adapter

They fail over time....i replace mine bout every 2-3 years.....

I also switched to the TP Link manuf. ones...I don't think so, had it failed it completely wouldn't work? It still is in working condition. No...they usually start by disconnecting intermittently.....like yours is doin now.
Try it in a different computer. If the same thing happens you'll know for sure that you need a new adapter.It's 15 Bucks fer cryin in the soup...like trying to diagnose a mouse failure and waste time fixin it...
