I’ve found WPA2/WPA3 mixed mode to be very hit and miss for a few legacy devices unfortunately. They can see the SSID, but they simply won’t connect even though it’s supposed to be ‘backwards compatible’.
I’ve basically done what was mentioned here and went with 2 SSIDs on my network. One for modern devices that uses WPA3 exclusively and allows for all 3 bands along with Wi-Fi 7 features such as MLO. And a second one for legacy devices which uses WPA2 exclusively and only supports the 2.4 GHz and 5 GHz bands.
Even then, Wi-Fi 6E devices are in an awkward middle ground. While they all support WPA3 and can use the modern SSID, they don’t support MLO so they can sometimes hang on to the 6 GHz band which drops off more quickly at a distance instead of switching to one of the other two bands when appropriate.
That would have been true of any upgrade to the WPA algorithm, WPA2 was released in the mid 2000s.
Although I didn’t know it was mandatory for WiFi 7. At the end of the day you should be able to pick if you want to run WPA2 or WPA3.
Yeah, the trouble is with the fact that there is essentially no way use a single SSID for all you devices if you want wifi 7.
WPA2, and you can’t run 7. Turn on 7, and not all your devices can connect.
To get the best of both you have to split your network into two SSIDs.
You can set a SSID to use WPA2/WPA3 mode though so old devices can still connect.
