Question Networking for Dummies

[BoomerD]

For some reason, the ethernet connection in my wife's Dell PC has stopped working. Running Windows 10. It's a Realtek adapter, (I can get the complete info if needed) I've downloaded the latest drivers from Dell. (from 2015...it's an OLD PC)

I changed my wifi router yesterday to a better/faster model. This seems to have happened as a result of that change. It took me a while to get her wifi back up and running...but for now, THAT seems to be working. <cross fingers>

I changed the ethernet cable to a known-working cable. (CAT6) so I DON'T THINK that's the cause of the problem.
The port her PC is connected to on the router shows it's connected, but it just doesn't work.

When I run ipconfig, the info basically matches the ipconfig for my pc.(IPv4 and 6 are different...since they're different computers, but subnet mask and default gateway match.

What am I doing wrong? I suppose it's possible network adapter in her 2014 Dell has died...but I think it's something else.

NCSI "No Internet" false alert issue is quite annoying. I believe most people encountered the false alert more than once during his lifetime using Windows.

An Internet Explorer or Edge window opens when your computer connects to a corporate network or a public network - Windows Client

When you connect a computer that's running Windows 8 or later to a network under certain conditions, you may see a sign-in page or the MSN Portal page.

Like dis? (posting from MY PC, working on hers)

I always chuckle when people redact local network information like this. These addresses are either private (IP4) or local (IP6) and can only be reached within a local network.

I'm glad I could amuse you.😎

In this case, better safe than sorry isn't a bad motto.

:\ Well normally i wouldn't ask for a ipconfig, but it was trying to debug his physical card and not ip address, as i was thinking something phyiscal might be an issue more then driver / setting.

In this case, better safe than sorry isn't a bad motto.

yep, like how it posts he has 11 other network devices.

Do you mean all this?

1. Press Windows + R keys.

2. Type regedit, click OK.

3. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet.

4. Make sure following values exist in right pane of Internet:



"ActiveDnsProbeContent"="8.8.4.4"

"ActiveDnsProbeContentV6"="2001:4860:4860::8844"

"ActiveDnsProbeHost"="dns.google"

"ActiveDnsProbeHostV6"="dns.google"

"ActiveWebProbeHostV6"="www.msftconnecttest.com"

"EnableActiveProbing"="1"

Ok if anything required a regedit, it means 4 things.

A System command was drawn to allow registry edits, which is usually something very important to windows,
It was created on Software install and rarely gets edited manually.
Malware / Virus
Bad or Dying hardware which caused a bad read or write.

It could of been the result of you installing all those drivers, that registry was edited.
But you said it wasn't working before, so im thinking you might have a malware.
I would scan my PC for malware.
