This issue is annoying to say the least. On the task tray, I am told that there is no network connection, however I am able to browse the web. But due to it claiming no connection, the app Your Phone does not work, because it can't detect an active internet connection. I ran the network diagnostics/troubleshooting and it said that it needed to reset the adapter, so I allowed it to do so and then restarted the system, but nothing changed. I am wondering why this is showing up like this, previously it has shown no connections, but shortly after I start browsing it disappears and switches to showing an active connection. This is a wired connection, however the motherboard does support WiFi, but I am connected via Ethernet.

Not an answer but at least and acknowledgement, I've had that very thing happen and eventually a reboot addressed it but I have no idea what caused it or what really fixed it.  Hope you find the cause because I'm sure it will happen again.

do you do any vlan setups or vpn setups on your network?

 

I seem to remember reading a topic with this exact issue about a year ago on these forums and it was caused by a bad setup with one of those things.

as usual it was @BudMan to the rescue so hopefully he can help you as well 🙂

NordLynx vpn, and then 'network' both of which indicate no connection. Should I uninstall NordVPN?

You uninstalled that vpn whatever you had installed?

 

That for sure would/could mess with MS detection of internet access.. Which is normally done via dns query.

 

What are you pointing to for dns?  After you uninstall any vpn anything..

 

What OS you running?  Windows 10?  What build?

Assuming Windows 10:

 

...can you screenshot your connections ... might be helpful to see what is going on.

Typing at the start menu, without quotes, "Network Connections"

You can use the snipping tool to take a screenshot.

 

Might also be helpful to copy/paste your network properties:

Here is how windows 10 knows if your online or not.

 

Windows 10 or later versions:

NCSI sends a DNS request to resolve the address of the www.msftconnecttest.com FQDN.

If NCSI receives a valid response from a DNS server, NCSI sends a plain HTTP GET request to http://www.msftconnecttest.com/connecttest.txt.

If NCSI successfully downloads the text file, it makes sure that the file contains Microsoft Connect Test.

NCSI sends another DNS request to resolve the address of the dns.msftncsi.com FQDN.

If any of these requests fails, the network alert appears in the Task Bar (as described in Symptoms). If you hover over the icon, you see a message such as "No connectivity" or "Limited Internet access" (depending on which requests failed).

If all of these requests succeed, the Task Bar shows the usual network icon. If you hover over the icon, you see a message such as "Internet access."

 

If you have some vpn software that is messing with that, or dns filtering going on, or any sort of security software that blocks such access then sure you could have issues with windows knowing you have internet access.

Under no circumstance should a ping test be blocked that triggers connectivity alerts.

 

That is in its own definition, idiotic. Why do they do it? Because they think they are blocking malicious phoning home.

Yep Android does and you shouldn’t use stupid garbage to block that either. Why exactly should I stop using Windows 10?

So, i had this with a couple of versions of Win10.... be helpful to know what version and build number you are on!

One of the things i would do that would get the connectivity to show as connected (even though reboots didnt help) .... cmd as admin, ipconfig /flushdns then followed by ipconfig /renew

 

OR, in device manager, delete your NIC & Wireless adapter .... reboot, and let windows re-detect the devices. 

I use Express VPN (NordVPN throttled me too much).... so i also would uninstall the VPN client... reboot, see if your connection shows correctly, then install the last version of the VPN.

 

Again, this worked for me on some insider ring versions of Win10... it has been much more stable as of late though :)

Well overnight it must have decided that all the criteria was meet, because this morning the task tray icon is showing connected, and I was able to use the Your Phone app.

I am going to uninstall the VPN, since I have no use for it, but it is very odd to me that for two days, and reboots, that windows never got the response it was looking for, yet overnight it managed to...

@Marujan That is very interesting information, but I have not used any program like the one you mention, but it is very nice to know that it can cause more problems then it supposedly protects from!

The reason why it says there is no internet connection when there is one is because it cannot connect to some specific Microsoft servers.   Behind a content filter, this is a bit of a common occurrence.   It can be ignored as it is not a good indication if you do or do not have an internet connection.  
 

you aren’t alone in this “issue”. it is a false message, but it probably annoys you

 

here are a few things you can try

    • Microsoft Edge gets new password feature and security fixes

      By TarasBuria · Posted

      Microsoft Edge gets new password feature and security fixes by Taras Buria Microsoft has released a new update for the Edge browser in the Stable Channel. Version 137.0.3296.83 introduces a new password feature and fixes security vulnerabilities to make your browsing experience safer. Starting with new features, Microsoft Edge 137 now supports Secure Password Deployment. Microsoft recently announced this for IT admins, allowing them to share encrypted passwords with user groups. This service lets users log into websites without seeing their passwords, thus enhancing the organization's security. You can read more about Microsoft Edge Secure Password Deployment in our recent article here. Security updates in Microsoft Edge 137.0.3296.83 include two fixes for Chromium vulnerabilities: CVE-2025-5958: Use after free in Media in Google Chrome prior to 137.0.7151.103 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High) CVE-2025-5959: Type Confusion in V8 in Google Chrome prior to 137.0.7151.103 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High) You can update Microsoft Edge to the latest version by heading to edge://settings/help. The browser can also update itself automatically in the background and apply updates between restarts. In case you missed it, Microsoft released Edge 137 by the end of May. The update deprecated quite a lot of existing features, including Wallet, Image Editor, Image Hover, Mini menu, and Video Super Resolution. It also introduced Web Content Filtering and enhancements for the picture-in-picture player and Find on Page in Microsoft Edge for Business. The next feature update for Microsoft Edge, version 138, is expected on the week of June 26, 2025, as part of the standard four-week release cadence.
    • Microsoft commits to upskill 1 million UK workers in AI this year

      By zikalify · Posted

      Microsoft commits to upskill 1 million UK workers in AI this year by Paul Hill Microsoft has partnered with the UK government in the latter’s ambitious plan to train 7.5 million workers in AI skills over the next five years. Specifically, Microsoft has committed to upskilling 1 million of those workers by the end of this year. This represents a significant portion of the overall target and within a very short timeframe. The education drive by Microsoft builds on its previous “Get On” program, which has given 1.5 million people basic digital skills. The effort to train up 1 million British workers in AI is part of Microsoft’s broader £2.5 billion investment in UK AI infrastructure. Ensuring workers have the skills to leverage AI tools is important. Microsoft CEO UK Darren Hardman said recently that two-thirds of business people wouldn’t hire someone lacking AI skills, showing just how vital it is to get people’s skills up to date. Microsoft's approach to AI skills development Microsoft has several platforms to offer AI training, including Microsoft Learn, AI Skills Navigator, and through partnerships with non-profit organisations such as Catch22 in the UK. Its educational materials cover everything from the basics of generative AI to helping you prepare for advanced roles like being an AI engineer. With Catch22, Microsoft helps to train people who face various challenges to getting tech skills, including gender and ethnicity barriers, homelessness, mental health issues, school exclusion and disability. Microsoft is also trying to get more women into tech fields through programmes like TechHer, where it has trained thousands of women across UK government departments. Many of the courses that Microsoft offers come complete with certificates that you can show off on your CV when applying for a job to impress potential employers and land a job. Who else is partnering with the UK government? While Microsoft is playing a massive role in the government’s plans, it’s not the only big tech giant helping out. The firms that have partnered with the government are: Accenture, Amazon, Barclays, BT, Google, IBM, Intuit, Microsoft, Sage, SAS, and Salesforce. While all of these firms are helping to train workers, Microsoft’s planned efforts are the most notable. This initiative by the government will help the country brace for the changes AI is expected to bring to the economy. In April, the United Nations said that AI will affect 40% of all jobs, so being ready is a must.
    • Microsoft has an update on Exchange Online Basic Auth removal for Office 365

      By hellowalkman · Posted

      Microsoft has an update on Exchange Online Basic Auth removal for Office 365 by Sayan Sen Back in 2022, Microsoft announced the retirement of Basic Authentication as it was moving to modern OAuth 2.0 token-based authentication. The reason was simple, to move away from such simple username-password authentication to more secure sign-ins. While Microsoft had previously planned to "permanently remove support for Basic authentication with Client Submission (SMTP AUTH) in September 2025", the company has now updated this timeline, adding a final delay. Perhaps this was on the cards given that Microsoft recently extended Basic Auth support for High Volume Email to 2028. On the Microsoft 365 Admin Center, a new message has been posted that details the changes regarding SMTP (Simple Mail Transfer Protocol) AUTH Client Submission. The message says: Thus, starting March 1, 2026, Exchange Online will begin phasing out Basic authentication for sending emails via SMTP AUTH. At first, fewer attempts will be blocked, but by April 30, 2026, this older method will be fully disabled. After that, any apps or devices that want to send email this way will need to use OAuth. The message further adds how admins can proceed with the changes in case OAuth is not supported: Users who have access to the M365 Admin Center can view the message under ID MC786329.
