Hey @Tbuschle .
Thanks for replying.
Since posting I discovered that the 2016 USB network adapter on my old Dell 7450 laptop was not compatible with my new Google Nest Wifi PRO network. For that matter, documentation didn't list Windows 10 as being supported with the adapter that I was using, but it worked until I changed to the Nest/Mesh system to utilize my recent change of ISP to fiber @ 750 Mbps.
As for you questions for future use:
Thanks for the update @Tbuschle .
It sounds like the issue is the adapter and compatibility. Try disabling 160Mhz channel and test. If the issue still persists, disable IPv6 as well. I'd also check to see if WPA3 is enabled as it can cause issues with older devices as well. While special characters in an SSID have been known to be a problem, it doesn't seem to be so here unless it changed also.
Please let me know if you are able to get it resolved with the above or if you still have issues.
This issue is resolved. I am however having issues understanding the complexities of the Google Home app and it's relation to my Google Nest Wifi PRO. Documentation I am finding internally in the App doesn't match what I am seeing on the screen.
Is there up to date documentation (hopefully with screen shots) available anywhere?
