You're not the only one
Yeah you've had a rough time of it lately. The annoying thing is, every time I think I've found a solution to it, the connection drops maybe half an hour later. It took until 2am to find what should solve mine, it was a small setting that was changed when I went from Win7 to Win10. Hopefully it holds out because I know its not my ISP on this one.
Was it a power management setting? I had the EXACT same kind of problem. Connection would drop randomly, DNS error, Event ID 1014 in Event Viewer, only started after most recent Windows update. I went into Device Manager > Network Adapter > Properties > Power Management and unchecked Windows being allowed to turn it off to save power. Haven't had a problem since.
that was the exact thing I changed last night... wasn't the issue as it happened again today. I run a powerline adapter just with where I am in the house relative to my router. I think I have it diagnosed that sometimes I need to put one of them into a different socket to sort it. Either way, since I've changed that I've been fine :)
I use a powerline adapter too lol. Hasn't happened to me since Monday. Hopefully it's fixed for you. If not you should update drivers for your Network Adapter.
Windows 10 tho, what a POS.
trust me, anything you can think of I've probably given it a go. At the time of writing the issue has not arisen since I changed the socket so I'm hoping that's it grand for now
