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

Anonymous

I am running on Windows 10 Enterprise, Version 2004, OS Build 19041.264.

I recently changed to the Windows Insider Program and updated Windows. In the taskbar, the Wi-Fi icon shows No Internet Access, but I have a stable internet connection wirelessly (Ex: I can browse the internet, ping IP Addresses, etc.). Another problem is when I try to open Cortana it also says that I have no internet connection (By the way, I can also open Microsoft's website).

As I know Windows checks internet connectivity with this URL: http://msftconnecttest.com/connecttest.txt. But this gives Error 404, File Not Found. Maybe it is because of this?

If you know the problem or an answer, please help. Thanks!

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

The proper one is

"HKLM:\SOFTWARE\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator\” -Name UseGlobalDNS -PropertyType DWORD -Value 1 -Force

But the more appropriate way to do this is not through registry directly, but through group policy config:

Here's a more complete one that I use:

((dns.qry.name contains "www.msftconnecttest" || dns.qry.name contains "msftncsi") && dns.qry.type == 0x1)

|| http.host contains "connecttest"

|| ip.src == 13.107.4.52

|| http.host contains "msftncsi"

|| ((ip.dst == 13.107.4.52) && (tcp.flags.syn == 1))

If you are absolutely not seeing any DNS or HTTP coming from PID matching nlasvc then your active probing is not enabled. I know despite a lot of crazy history in this thread I can't even get my hands around I think you had registry values correct....but maybe not.

@ StepSnake and ToddMillercam: Yes, it is EXACTLY crazy stuff like this with W10 now, that has made me move to Linux. If you have not tried any Linux before, I suggest you start with Linux Mint. It is very popular, and easy to migrate to from a Windows users' point of view. That has been my experience anyway. It is still different - it is Linux not Windows afterall, but Mint is I think one of the best and easiest distros to use if you are coming out of Windows. As with most Linux distros, you can run Mint from a live-DVD or a USB flash drive without touching your Windows install, to try it out and see if you like the look and feel - but live versions like this will run much slower then a proper install would, due to the speed restraints of DVD or USB access. A USB3 flash drive on a USB3 port would be the best way to try out any version like that. I have several server boxes on my LAN, and they all run Linux, cos it just goes and goes and goes 24/7/365 and never insists on reboots for updates or anything like that - YOU are in control of when it reboots, and YOU manually update - if you want or need to.

As I only have this one W10 machine left on my LAN now that I need to use just for my Windows-only CAD software - and Spotify for music while I design inside the CAD software, then I can essentially ignore the issue now that I can use Spotify via a web-browser window. I totally and completely acknowledge that this is no solution for lots of others who DO need to use other apps that insist on talking via the NCSI nightmare thing.

I would actually downgrade and install an earlier Windows to get around this issue, but my dinky wee Intel NUC does not support anything earlier then W10 drivers wise, so it's W10 or no Windows at all on this NUC. Linux auto-detects all the hardware fine, so I could move it to Linux, but I can't cos the CAD software needs Windows, so I am sorta stuck with W10 on this one last Intel NUC machine.

I did setup WIRESHARK on my Ethernet connection on this NUC, capture filter "host 13.107.4.52", and display filter "ip.addr == 13.107.4.52"(ALL other filters deleted) to try to see any traffic to and from the MS IP, but after more then one million packets, there was NO DATA.

Perhaps if Tom(MS engineer) reads this, he could comment if I have the Wireshark filters setup correctly?

IF the NCSI app is actually never making the attempt to poll the server past boot-up for whatever reason, that would actually explain the problem completely, as if it never polls the server, it would never get a reply, and would time-out and show the globe icon - which would never be able to self-correct, as it is never polling the server - unless you reboot. Just a wild guess at this point. ;)

Thank you. I will give tvis a shot. Unfortunately, it won’t be this week.

So, I have an awful fix/work around, and it's involved and your situation might not be the same as mine.

1. Make sure Hyper-V and containerization is enabled (I suspect this is where the root of the problem is at in the MS code)

2. Check your adapter options and make sure a vEthernet adapter is there

3. On one of your physical connections, disable everything involving ipv6. For me, I have it stripped down to the following adapter properties:

- Client for MS Networks

- File and Printer Sharing for MS Networks

- QoS Packet Scheduler

- Reliable Multicast Protocol

- TCP/IPv4

- Microsoft LLDP Protocol Driver

- Link-Layer Topology Discovery Responder

- Link-Layer Topology Discovery Mapper I/O Driver

4. When you boot up, it will still show as no-internet. Go to adapter options and disable the vEthernet, then after a few seconds you'll have connectivity

You have to do step 4 every time you restart your machine.
