Windows 10: Computer is connected to WiFi, says is connected to internet, but cannot reach a single...

I've had this PC Windows 10 for over 5 years, the internet has always worked for me up until now. My computer connects to the internet through WiFi, and so do all of my other devices. Recently, I've found this issue that my computer is connected to WiFi, says I'm connected to the internet, but then proceeds to not work with anything that requires internet. My other devices are fine, the WiFi isn't the problem, it's only an issue on this PC. I've tried multiple browsers and platforms and they all don't work. I've tried every single solution I could find online, from flushing my DNS to restart

Wifi Connected Can Access Internet but Network Computers Can't Reach I

The error I get isn't on the machine I am trying to contact, it is on the machine I am using to get to that other computer. I have tried to have that error analyzed or fixed by clicking on that option and it does nothing to help. When I get that error dialog box again I will take a screenshot and post it here. Thanks again

Attached is the screenshot I mentioned above, which I get when trying to access that laptop.

Got to thinking you may want me to try the Diagnose button so I did and attached are the screenshots of it. The first one is the next dialog box that comes up and the next one is the last diagnose box appearing before closing it.

 

Connecting computer with no internet connection to network printer


@dk1971

1. Open Admin command and type: ipconfig
   
   
   
2. Win+X->Control Panel->Netwok and Sharing Center
   Follow the screen shot. This should disable internet access from this PC but allows access to local device(s)
   NOTE: Use the IP & Subnet Mask from step 1. Leave Default gateway & DNS Server blank
   
   
   

 

I am connected to the internet, but in the toolbar it says Not Connect


I am connected to the internet, but in the toolbar it says Not Connected and Connections are available.
I am referring this to the Wifi Icon on the Bottom Right Corner near the Clock (Notification Area). There is no yellow asterix and I am properly connected to the internet. When I click this Wifi Icon , a window pops up and on its top it shows my ssid and below it shows connected. Disconnect option is also here.
Please suggest some remedial measure.
I have already changed my Wifi adapter - previously it was Wayona and now I am using Prolink. Both works well.
Thanks in advance.
