Monterey 12.2.1 Internet Over WiFi is Inconsistent
I have installed a clean Monterey 12.2.1 OS on my MBP 15" (2018). When connected to WiFi, the wifi icon shows strong signal and is persistently connected but Internet navigation is inconsistent. Some pages will load while others will not. Music and the App Store apps will not load content. My AppleTV on the same WiFi network can successfully test my Internet speed via the Ookla app but the MacOS version of the Ookla app fails repeatedly, reporting that I'm not connected to the Internet despite the fact that I'm streaming a YouTube video concurrently. Mail reports connection errors. When I switch to Ethernet, all works wonderfully. I am now preparing to downgrade to Big Sur to see if normal functionality is restored. Any suggestions and insight are appreciated!
