Computers are reporting "no internet connection" but the internet is working!
I have a clients site where half of the computers were reporting that there was no internet connection but the internet was working. All the computers are Windows 10 Pro computers. The router is fairly new and it is a Netgear Orbi. Their internet service is with AT&T. We powered off the router and rebooted everything and now all the computers are reporting no internet connection even though the internet is working on all computers.
The Icon is part of Microsoft's Network Connectivity Status Indicator (NCSI) https://learn.microsoft.com/en-us/windows-server/networking/ncsi/ncsi-overview
Starting with Windows 10, Microsoft connects to www.msftconnecttest.com/connecttest.txt to get the indicator to show as connected. It sounds like your Orbi is blocking your connections to it.

Is there away to turn that function off? Do or should I call Netgear tech support at this point?
On any computer not connecting to the internet open a command prompt, elevated with admin rights, and run nslookup. Check amazon.com and see if it resolves.
My guess is the router is not configured to passthrough the DNS from your ISP.
for testing purposes go to any computer and manually put 8.8.8.8 in DNS and test, if it works then you know the router is not resolving DNS. If it's not the router then it's your ISP.
If you don't know what settings you need to adjust on the Orbi, then call Netgear.
Check if you can ping the site. Then check if you can visit the site. It should just pull up a plain text file that contains:
Microsoft Connect Test
As per my experience, there is a small Microsoft utility which keeps checking if the Internet connectivity is there or not. If that tool fails for any reason, it indicates "No Internet connection".
Another reason is that you are using any proxy. Sometimes this MS utility cannot get through the proxy server.
However, there is not any problem with the internet connection. You can safely ignore that notification.
As far as I recollect, that flag is set if the workstations are able to ping a microsoft server in a certain fairly short amount of time...
If anything delays or blocks that, you get the "no internet" flag.
