LotusPilot: Very fair points. I am running multiple wireless networks with one being pure WPA2-Personal, and the new network as a pure WPA3-Personal, so the iPad is still able to connect to the WPA2 network without issues (minus the fact I use a 64 character PSK and was randomly generated and I usually mess up one character). The recommended settings page you listed above does recommend WPA3-Personal as a preferred configuration for wireless networks. My iPhone 12 Pro Max, my wife's 12 Pro Max, my MacBook Pro 13 (M1), and her MacBook Air (2019) connect without issue. My AppleTVs are all wired so I did not attempt that.
My concern is my iPad Pro 9.7 Gen 1 is on the latest iOS (14.4 a/o 12-Feb-2021) and cannot connect to a WPA3-Personal network. I did restore the iPad last night using 14.4 from my MacBook Pro, did not restore from backup and set it up as brand new. It would not connect to the WPA3 network. My wife's Microsoft SurfaceBook 2 will not connect either. That has a driver limitation that could potentially render it unable to connect to WPA3 networks (unless Microsoft puts out an updated driver). My Alienware 15 R4 and Razer Blade 15 both have updated drivers supporting WPA3, so those systems were able to connect.
My major concern is that I see nothing from Apple that says my iPad Pro is incompatible with WPA3, but I am not able to connect to a WPA3 network with it. My assumption (and I have to take on that I am wrong with this assumption) is that as long as the device is receiving current iOS updates, it should be compatible. Again, I assume I am wrong by the SurfaceBook 2 example where Windows 10 is capable of WPA3 support but the driver for the wifi card is not. Is the iPad Pro 9.7 Wifi Gen 1 incompatible with WPA3-Personal (again, it shows compatibility with WPA3-Enterprise)? If so, is this a bug or design? I am going to break out an old iPhone 6s+ that can run iOS 14.4 and see if it has similar issues as my next test.
