Windows 10: Resolve network issues

You'll restart the machine at least once.
Save any work, close open programs.
Any unsaved work will be lost.

The run command (WinKey+R or Run on Start) quickly gets you to Network Connections

In the Run dialog, enter:
ncpa.cpl
After each suggested solution, see if the issue is resolved.
If one suggestions fixes the issue, you do NOT have to do any of the other suggestions.

There is a tool that resolved all of my Network Issues

All,

I finally found a great tool that someone else that was having the same type of problems found. Tweaking.com

It is a free tool and just like everyone else I had the problems of:

Private Network Not Connected

Public Network Connected

Unidentified Network

Showed my Ethernet Connection was working properly but still couldn't access the internet

Tried reboot

Tried Troubleshoot repair

Tried Registry Edit changes

None of the above worked and this was my 3rd day to tray and resolve this issue because I couldn't find any help from Microsoft.

No Resolve Issue

You're welcome John

 

Thanks for that awesome tutorial!

Crossing fingers and toes and all other appendages that I won't need it with the new Win10 box.

But excellent to know it's there, just in case.
Thanks for taking the time to pull together those steps (I got lost reading the very long threads).

Cheers,
MM
