There is a question about how Windows 7 checks for Internet connectivity (which leads to a SU blog article).

I have a Windows 10 machine which currently displays

enter image description here


  • I do have internet access (browsing works fine)
  • following the article I tried both checks mentioned there (resolution od an address and retrieval of a page, or resolution of another address to check the IP) and both are successful

Is the check on Windows 10 different?

Note: the connection is a straight one, without proxies (I mention this just in case as there were discussions about proxies either blocking attempts, or requiring an authenticated connection)

    Per reddit.com/r/Windows10/comments/4p6r9r/… "On my Windows 10 the URL is www.msftconnecttest.com/connecttest.txt and ipv6.msftconnecttest.com/connecttest.txt, and the site ipv6.msftncsi.com exists too. You may need to whitelist them all." Dec 6 '18 at 15:26
  • @BobtheMagicMoose: thanks - I just checked and it is also available and the content reachable.

  • Ah, sorry I misread your question. I believe the icon/status is sometimes just confused. :D Dec 6 '18 at 15:30
  • This might be caused by the anti-virus. Which anti-virus have you installed?

    I can confirm that the indicator gets 'stuck' sometimes thinking you have no connection when you do. Most of the time, just reconnecting to the network seems to fix it, but sometimes it persists. Dec 6 '18 at 20:11

If access is confirmed and your icon shows the yellow exclamation, then one of Microsoft's "phone home" sites is either blocked at the firewall, through your virus protection software, or any number of Windows 10 blocking software (O&O ShutUp10). Windows 10 determines internet access through this "feature". Hope that helps.

  • Do you mean the measures I mentioned (linked articles and checks)?
