Windows 10 says I have no internet connection, but I have.

Hello, use Registry Editor, go to: 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet

and modify: EnableActiveProbing

then change "Value data" from "0" to "1"

and restart your computer

This is the only solution that works fine! Thank you very much.

I specifically have a Lenovo T590 running now Windows 10 build 2004.  This issue preceded the update to 2004 however, although it appears to be a much more frequent issue since updating to 2004.

I'm currently running the stock/factory image from Lenovo.

I've done the following:

1. Disabled IPv6
2. Disabled active internet probing.
3. Uninstalled the generic Windows USB-C Lenovo driver.
4. Installed the actual Lenovo USB-C Ethernet Driver.
5. Uninstalled RMM, AV, and other monitoring tools.
6. Uninstalled/Reinstalled all relative network drivers (including Wi-Fi)

The issue happens intermittently still.  Lenovo support was useless. I personally feel this is a bug with Windows 10 considering other people with different model computers are having the same issue. I'm hesitant to rebuild the computer from the ground up but think this may be the logical next step.  I was happy to read that MS has acknowledged the issue, but wish there was more updates on this.

As I'm typing this, my connection just changed telling me I do not have internet access even though I'm on a conference call and am adding this message.

**Update 8/28/2020**

Disabling VPN adapters may have resolved the issue.  When I connect to VPN, it shows I'm connected but will eventually register the connection as "Not Connected."  When disconnecting from the VPN connection, the connection immediately registers as "Connected." I can reconnect to VPN and it will randomly register as disconnected.

I still believe this is a bug with WSA or Windows' 'Winsock' platform, but at least for me, it seems to be making a difference with regard to the registration status of the Internet.

None of the aforementioned steps immediately resolved the issue, however using the most up to date driver(s) from the manufacturer (not Lenovo) have helped to a degree.

**Update 2 - 8/28/2020**

Windows 10 doesn't allow you to change the adapter binding priority via the GUI, however you can adjust the adapter binding via powershell:

1. Open PowerShell with Administrator privileges.
2. Type Get-NetIPInterface -ConnectionState Connected
   • You should see an output like the below:
   • The ifIndex value is what you want to pay attention to as well as the InterfaceMetric.  The lower the InterfaceMetric number, the higher the priority.
   
3. In my case, I wanted to make the USB-C Dock Ethernet adapter, the highest priority.
4. Type Set-NetIPInterface -ifIndex 15 -InterfaceMetric 5
5. Type Set-NetIPInterface -ifIndex 53 -InterfaceMetric 10
6. Type Get-NetIPInterface -ConnectionState Connected to confirm the changes.

Alternatively, you can set all of the interfaces to use an Automatic InterfaceMetric which allows Windows to prioritize them based on the number of connections you're concurrently using. To do this type:

Set-NetIPInterface -ifIndex ## -AutomaticMetric Enabled   **Note** - I don't have AutomaticMetric enabled for any of my interfaces.

A restart of your computer may be needed.  I'm not doubling down on this, but all of these steps in combination have made a significant improvement in the way Windows 10 registers (or lack there of) the internet connection.

Thanks...but tried this...long ago.  EnableActiveProbing is set to 1.  Even tried setting to 0, rebooting, then setting back to 1 and rebooting...nothing.  Are you saying to Delete the DWORD and then recreate it?  Don't see how that would help, but may try it.

Hi,

I just shared my experience. On the path 

"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet" I had not EnableActiveProbing. I created it as an DWORD(32-bit) in the screenshot presented in my post. After setting it to 1 and restart worked. My laptop access internet router by Wi-Fi. Your problem can be different. You should check the driver of net hardware in your device.

Please note that you can send feedback for the problem using troubleshooter (for Wi-Fi) then send feedback and the  Feedback Hub is active without being signed-in.
