Unable to update to Windows 10 and now I have no access to wifi on this computer

[Somerandomguyed]

Here's the problem, I was hoping that updating to Windows 10 would allow me to play Rainbow Six Siege, which I had just purchased but the game wouldn't start up in steam, had a lot of troubleshooting and so I thought it was time to update to Windows 10.

I go to microsoft and download their free update, let it finish and by the time it gets to 80%, it restarts and sets it back to Windows 7. Now it tells me that my copy is not genuine (it is, I even have the stickers for the product key). I reactivate Windows, do the phone key thing, but now I can't even connect to the internet. Nothing is wrong with my router because I am able to connect through other devices. My adapter hasn't gone bad either, it works if I connect it through my brothers PC.

I've troubleshooted the networks, saying that there isn't a valid IP configuration but... I don't get it. I've already done tried netsh winsock reset and netsh int ip reset but nothing happens.

Can anyone help?

Begin by going over the IP settings. Are they correct? Compare them to some other device on wifi, for example your phone, a tablet, etc.
Once the IP settings are confirmed, then test.

Try getting a copy of the WiFi NICs drivers.
Try re-install the system drivers as well if just the NIC drivers don't help.

Funny thing is, I just updated my drivers. So I don't know if it has to do with that. And I checked the IP address both on my pc and brothers. Both are the same.

Which drivers did you update? And where did you get them? I would check if you have the latest WHQL drivers for both NIC and the motherboard (System Drivers).

My GPU drivers, wifi drivers (netgear). That's about it though. All from the nvidia and netgear websites.

I should say that my motherboard is old, and aren't really being updated anymore. It's an ASUS Crosshair III Formula. But the network adapter is up to date (realtek)

I suggest you get the latest system drivers regardless and re-install them as I have suggested repeatedly.
They can often resolve issues such as an onboard NIC not working as it should.

Updated drivers, problem still persists.
Even after resetting pc

Updated drivers, problem still persists.

Have you tried uninstalling the NIC and then installing it over again?

Have you used sysinternals autoruns to see what starts with the PC?
Have you tried SFC /scannow and DISM?
Have you tested this PC on a different WiFi network?
Have you considered a repair install? This preserves your install programs but re-initializes every windows setting.

As an aside, my assumption that I am following is this:
You say you have verified that you have the 100% identical settings to a working system. And that your hardware is in good working order, the nic is turned on, and enabled in the device manager.
If the above is true it almost has to be the drivers. It is looking like a blown TCP/IP stack, but I haven't seen that since the winsock days in the 90s. And I am trying to avoid recommending you reinstall the OS.
