No vaid IP Configuration

[Fred Claus]

I'm at a loss. I have a client computer that won't connect to the internet. I ran diagnostics and it says the Ethernet and the Wifi have no valid IP Configuration. The network Default Gateway is blank.

I've tried removing the drivers and letting the system scan for hardware changes.
Updated drivers
Flushing the DNS - Renew won't do anything
DSIM scan
Checked the firewall to see if all traffic was blocked.
I've even moved the computer to a different location and tried their internet. Still no luck.

What am I missing

Resetting the network stack​

Note that these commands affect all of your networking adapters, both physical and virtual, both used and unused, so you will see some errors when running these commands, where the resets targeted adapters that are not being used. These errors are perfectly normal, and not a cause for concern. Complete each step in order, even if you have done some of these previously, and even if you encounter errors.

1. In the search box on the taskbar click Start, type command prompt, right-click the command prompt result and then select Run as administrator and confirm.
2. At the command prompt (decline restarting your machine until you have entered the final command):
   1. Type ipconfig /release and press Enter.
   2. Type ipconfig /flushdns and press Enter.
   3. Type ipconfig /renew and press Enter. (This will stall for a moment.)
   4. Type netsh int ip reset and press Enter. (Don’t restart yet.)
   5. Type netsh winsock reset and press Enter.
3. Now restart your machine using Start > Power > Restart once more and test to see if the issue is resolved.

/Release says it wont' do anything while the media is disconnected
/Renew says unable to to contact HDCP server

I also noticed that the IPV4 default gateway, DNS server, and WINS server are all blank in the details of the Ethernet.

Sounds like it could be a physical link issue, perhaps?

 

[Fred Claus]

Another words, I didn't miss something, but rather it's a bad nic card? The computer is 3 or so years old and this is the card that was built into the motherboard.

 

[Markverhyden]

Have you tried rebooting in safe mode with networking? Tried a brand new account? I just find it odd that both copper and 802.11 is down at the same time.

 

[phaZed]

Somehow missed it's on both Wifi and Eth.. Agree with Mark - would be odd that both go down.

Just did safe mode with networking and I'm getting the same thing. No internet on ethernet.

 

[Fred Claus]

Cancel that. Safe Mode with Networking just took a bit. It says I have an internet connection now.

Nice. Broken Windows networking stack or some Virus/malware, etc.

 

[urcomputech]

Try disabling IP V6

Yep. I'd bet an OS issue. Assuming it's W10 I'd try a repair install.

 

[Fred Claus]

ok doing that next. It is 10

 

[mikeroq]

Did you try booting a live Linux or WinPE and seeing if it connects? Or a USB nic or wifi?

Probably a Windows issue but doesn't hurt to try it in the future.

Forgot this.

 

[HCHTech]

I agree with @nlinecomputers

Windows 10 has a "Network Reset" feature in Settings > Network & Internet > Status (at the bottom of the page).

It automatically does all the steps listed above in this thread, and perhaps more. It has fixed things for me lots of times, when I used to do a repair install to fix.

I want to assume that Fred ran that and that is where he got the "doesn't have a valid IP configuration" Like this:

 

[cypress]

Yeah I would say run some malware scans and do a IP stack reset. I was also gonna suggest setting a static IP to see if it got back online.
But honestly Nuke a pave would be the best options hands down.
