No internet connection after upgrade to Windows 10 Version 1703

Have you rebooted the modem/router? By that I mean unplug it from the wall outlet for 5 mins. If that doesn't work, I would try resetting the modem/router......there's a tiny pin hole on the back of the modem/router. Use a paperclip and insert into hole and push and hold down the reset button until the modem/router goes off and comes back on then release the button.

Thanks. Yes I have rebooted and also reset both the modem and router but to no avail. Unfortunately, Microsoft no longer offers the version 1511 iso, so I cannot even revert back to version 1511. However, on eBay I have come across listings offering the Windows 10, version 1511 installation DVD's and my only alternative now is to get the DVD.

In my first attempt to get my old Dell up to Windows 10 it would not connect to the internet at all and everything I tried did not work.
The Deviice Manager said everything was ok but I knew it wasn't I reverted back to Win 7 but after about 10 days attempted it again. This time I looked real close at the drivers Windows installed, Realtek, and found my card took Intel drivers. I uninstalled the RealTek drivers and forced in the proper Intel drivers for my WiFi card. All was happy after that and has been since.
Just something to consider with your problem.

Hey MikeSA,
On one of your PCs (2nd set of screen shots / zte wireless terminal) the Default Gateway is 0.0.0.0 ... This is usually caused by Apple’s Bonjour service.

Open Command Prompt as Admin
route delete 0.0.0.0

Note: You may need to Disable then Re-enable the Device or Reboot.

I encountered that when I updated to 1703 and solved mine when I disabled "Let Windows manage this connection". Just kiked to share that so perhaps others may add in. Goodluck!
