Windows 10: Wifi connecting and disconnecting without reason on my pc. No internet connection

Hello, First of all I am not a professional and kinda a newbie concerning pc and techno stuff. Sorry in advance. Here’s my problem :Since a week, impossible to connect to my wifi on my pc without it disconnecting every minute. It says ‘no internet connection’. Keep in my mind that my wifi works perfectly fine for all my other devices, and since I upgraded my wifi to a stronger one 6 months ago, i didn’t have any problems. Here’s the thing I did to try to resolve it :-Turn off and on the wifi router for 30s-Trouble shooting network adapter : doesn’t help-Reset the networks -ipconfig /reset, /re

Connect and Disconnect internet

I just need to click the network icon in notification area, select my WiFi network and click Connect / Disconnect:





Selecting Connect automatically I don't have to enter the network security key manually:

 

Disconnected from Ethernet, WiFi still connected

Hello,
For the past 6 months I have had terrible internet issues, there was a problem within my area according to Virgin Media which was resolved 2 months ago. However occasionally I still get disconnected, but my Wifi stays on.

My PC is connected to the router via 2 powerline adapters. All devices which are connected to router wirelessly are fine and have a consistent high-quality connection. Whereas my PC has an inconsistent and sometimes low-quality connection. My speeds however remain optimal, around 46 Mbps download / 2.92 Mbps upload. The quality however is sub-par:






Sometimes I have around 2 - 10% packet loss.
Any ideas on why the PC connection isn't perfect whereas the Wifi connections are?

 

Connect and Disconnect internet

No it's not cellular. I have an internet service provider and I have a modem and a wifi router installed. In Windows 8 there was no issue as I described. In Windows 10 it's not that simple to connect or disconnect to my broadband. There are NO ISSUES connecting or disconnecting, I can do that but the steps involved are too many compared to the simplistic 2 clicks affair in windows 8.
