Windows 10: No internet after Win 10 update

My aunt did the free Windows 10 update from Windows 7. After the update she had no internet connection so she decided to roll back to Windows 7. After the roll back, she still has no connection. Her connection icon says "unidentified network" and will not connect to the internet. It is plugged directly into the modem. Does anyone have any idea?

Wi-Fi is on // No connection (after Windows Update)

On Oct 13 windows updated.

The update must've invited malware into my computer. I tried to run my antivirus after the update but it said there's no connection. Google chrome lost connection as well and then I got a pop-up saying that Windows Defender found and blocked a "Severe Trojan
threat". So I deleted it and I still don't have connection... (weirdly) the only thing that works is the Explorer app. I have internet; the Wi-Fi works just fine but, everything else doesn't connect. It's something internal that must be causing
the problem and it all started after the update.

P.S.

It also changed my network from private to public so I had to fix that.

And YES, I did allow these programs through the Firewall so that's not the problem.

still isn't working.

 

Restart the modem by unplugging the power and plug it back in and restart the computer at the same time?

 

At the command prompt, I get an error in ip infix saying "media disconnected." I've tried the reset commands that I found on the internet but it didn't fix it. I can't seem to find other things to try.

 

I meant an error in ipconfig.

 

You will want to make sure she has the LAN driver from her computer manufacturer. This might have solved the Windows 10 problem as well. Won't know for sure till you try it.
