I'm not looking to replace my current WiFi setup yet. Though if Apple does completely stop their Airport sales, I'll be looking for whatever the most recent thread here is to help make my decision on what to upgrade to. Glad to see the good info regarding the state of the industry can be found here

Thanks K447 for the info on the WiFi Explorer app, may pick that up. I'm always impressed with how well the built in WiFi tools work on macOS that I hadn't thought to look for more before. I do hope the OS tools stay decent, as by what I understand they were designed by the same folks from the Airport team that was rumored to no longer exist.
