Have had a bit of a dig, but come up empty - so am putting it out there.
Have a new AX3, 2nd time messing with WifiWave2 - and am having issues with an older client devices connecting to the AP/Router.
Have set up wifi fully "AX" mode, but using wpa2 and ccmp (aes) encryption in conjunction with wpa3 (also just ccmp so I don't have to go around and reconnect all my device)
The legacy device is a Nintendo New 3DS. It does not see the 2ghz wifi at all. If I drop the 2ghz to "N" wireless and lose the wpa3, it shows up and is connect able, while keeping the ccmp as is... I may have even left the wpa3 on in one test, it may have just been ignored.
I also attempted making a VAP with a lower "Band" (selecting n or g instead of AX), but obviously the VAP works it's channels at the same as the Master Interface (was hoping for a stepdown spoof or something).
Anywho - my question - is this expected behavior, not being able to connect legacy devices to AX wifi.
Old Wifi driver with AC let you select a/n/ac or b/g/n, but now you can't select multiple.
I know I have had this 3DS connected to Wifi6 aps before (however one of those may have had wifi4 2ghz radios like Wifi5 units did). I am pretty sure the consumer grade wifi6 stuff can do g/n/ax also, but it appears that my router, for the moment, can either do g/n OR ax (I say g/n as the 3DS apparently only has g wireless). More testing to go on, but any info anyone can put forward would be appreciated.
I'll have to crack out a few old lappies and see what shakes out.
As for the 5ghz can confirm AC/AX working, but again need to test N and A for connectivity.
In the meantime, I was replacing a Unifi AC/ER-X combo, so will put the Unifi back on with different SSID for legacy (small home so all g, but for work, moving forward, need to know these things)
