Unidentified Network / No Connection

After much skepticism towards Windows 10, I finally decided to give in and upgrade from Windows 7 before the deadline, but much to my dismay, I encountered this problem as soon as the new OS finished installing, and I was unable to activate the product before the deadline as a result. Over the span of these 2 days, I've spent no small amount of time sifting through similar issues from others, searching for a solution, and attempting many of the suggested answers. Troubleshooting lead to nothing in all cases, I've uninstalled my anti-virus software, I've tried using ipconfig /release and /renew , resetting winsock, as well as flushing DNS in the command prompt, whatever other suggestions barring the seemingly more extreme ones; nothing thus far has helped in any way whatsoever. I would like not to have to revert back to Windows 7, but 10 has given me little hope in a better solution at this point. Anything else that could potentially solve my problems would be much appreciated. If there is any additional information I could provide that would be of assistance to that end, I'd be more than willing to provide it if able.

Welcome to the forum. Can you open a cmd prompt type ipconfig /all and post results

Its not getting an ip as its getting default 169 range delete all the not used connections. Does the router show a light on the port to indicate a connection have you tried another cable?
Open an elevated cmd prompt ie find cmd.exe right click choose run as admin type each line press return
ipconfig /flushdns
ipconfig /release
ipconfig /renew /
netsh advfirewall reset
netsh winsock reset
netsh int ipv4 reset
disable ipv6
Can you get this on via usb or simliar

The router does show a green light for the connected port, I can't really try another cable, but the cable in use was working fine with that PC on Windows 7 right before upgrading.

That shows all network and blue tooth devices are set to disabled check in device manager and enable them

I thought I did check the device manager to see if anything was disabled early into this problem, but I re-enabled them all in any case as they weren't at that time, you were right. I restarted my computer, and plugged that cable directly into the modem, and that finally got that computer online. Unfortunately I believe my ancient router was part of the issue because I can't get anything else connected through it anymore, but I'll be having it replaced soon, and hopefully that will solve everything else.
Thank you very much, you've been most helpful, I greatly appreciate it.
