Windows 10 IPCONFIG Shows NO Adapters

Question

Wednesday, December 9, 2015 8:02 PM | 2 votes

I have a client that 2 weeks ago their Windows 10 was working fine. They turned the laptop off and then last week turned it back on and the LAN adapter along with the WiFi adapter will not connect to the network nor the Internet.

When you go into Device Manager, the adapters show up just fine. I even tried updating the adapter drivers and still nothing.

When you go to the elevated "Run as Administrator" Command Prompt and type IPCONFIG, this is what you are presented with;

C:\Windows\system32>ipconfig

C:\Windows\system32

No adapters show up.

Now when you type "ipconfig /renew" you receive this message;

"This operation failed as no adapter is in the state permissible for this operation"

My client really does not want to have me wipe out his machine to get it back working. Originally the laptop came with Windows 8.1 and was upgraded to Windows 10. I have scanned the hard drive using 5 different scanners and no viruses or spyware has been detected.

Does anyone have a solution to this issue? I would deeply appreciate it. Thank you.

After uninstalling the free AVG, I saw the adapters in the elevated Command Prompt but was not getting any IP address. I reran the MiniToolBox and after rebooting the workstation I am now receiving IP addresses and surfing the Internet.

I am in the process of running Malwarebytes to make sure it is clean. I ran the Eset Online Scanner and it showed no infections but want to make sure. Once the Malwarebytes is done I am going to fully patch the machine. Once it is patched I will download the latest version of the free AVG Antivirus and install it and see if it kills the network cards. I have never seen free AVG do this before. If it kills the machines network cards, I will let you know.

Thank you all for your input on this issue, I really do appreciate it.

Have you tried any/all of the following:

  • checking to make sure that the laptop doesn't have a physical switch that disables WiFi
  • checking to ensure "flight mode" or "airplane mode" is not selected (button on menu when pressing Winkey+A)
  • grabbing the latest drivers for the LAN adaptor from the vendor site (on a pc with internet access), dropping on a usb stick, and installing
  • right-clicking network adaptor in Device Manage and selecting "Update driver software" and pointing to the latest downloaded drivers (may need to unzip first)
  • deleting the devices in Device Manager and then doing a rescan to have them reinstalled
  • what do you see if you open the "network and sharing center" and select "change adaptor settings"

Thank you so very much for your response.

To answer all your above checks, I have done all of them already. Still have the same issue.

Please download this app (minitoolbox)

Run it with "select all" checked

Upload the output to one drive or any file sharing service

Put a link to them in your next post

Please type each of these into an elevated command prompt after you have run the above and saved the file

ipconfig /flushdns

ipconfig /registerdns

ipconfig /release

ipconfig /renew

NETSH winsock reset catalog

NETSH int ipv4 reset reset.log

NETSH int ipv6 reset reset.log

Exit

Hi,

I saw similar issue before, what antivirus or firewall software he using? Norton/Symantec Endpoint Protection or McAfee?

Try boot this machine into safe mode with network and check the issue, uninstall these antivirus or firewall software and reboot，give it another try.

Thank you for your input.

I have booted the laptop into Safe Mode with Network Support, same issue, not network adapters when you are at the command prompt and run "ipconfig".

The antivirus is AVG's free version. I thought maybe the client installed the 30 day trial of AVG's Internet Security and I have seen it that at 30 days, you have not Internet access, but I have never seen it kill the network adapters at the command prompt when running "ipconfig".

You are right, I am going to have to uninstall the AVG to totally eliminate it from the issue. Will let you know what happens.

Thanks again.

I've seen AVG install network layer and disk layer filters into a Windows Server 2012 machine in the past, in that case the disk performance dropped from 120MB/sec to 2MB/sec.  It wasn't until the AVG was removed that the disk started performing again (disabling wasn't enough).

I'm not sure what's happening in your case, but it is quite possible that there is something going wrong at the antivirus protection layer.

Thank you for your reply. I will remember what you said about AVG on the server. I have some clients that are running the business version of AVG and so far, no issues on workstations nor the servers but as I have just experienced, stuff happens.

Thanks again.
