After upgrading the router I was unable to use WPA3 for the 5GHz AC chipset
After googling little I realized that I have to uninstall wireless package and
replace it with two of the following packages
wifi-qcom-7.20.1-arm.npk and
wifi-qcom-ac-7.20.1-arm.npk
In order to install them I uploaded those two files using Winbox 4.0beta35 and Winbox 3.43 from windows 11x64 to the router and rebooted.
None of them get installed
In addition I used netinstall application to install wifi-qcom-ac-7.20.1-arm.npk in addition to the routeros-7.20.1.npk to get installed only I got wifi-qcom-ac-7.20.1-arm.npk installed not the other one.
I tried to upload the other .npk file I get not enough storage error as well.
In addition trying to use WPA3PSK on the 5GHz interface with CCMP GCMP CCM256 ,…. cause th AC In fact despite setting WPA3 as Authentication Type in the wifi2 security profile for the 5GHz SSID the router uses WEP encryption instead which is unsafe to use as well
How can I correctly install those two packages and solve the WPA3 Authentication issue for wifi2 interface the wifi2 interface(802.11ac)?
It's either wifi-qcom or wifi-qcom-ac ... not both. For hAP ac2 you need wifi-qcom-ac (wifi-qcom is for AX hardware).
Beware that quite many WiFi clients puke when seeing AP offering ciphering anything other than CCMP (and possibly CCMP256). In particular, none of client devices I was using at the time I was trying WPA3 (a year or so ago) could handle GCMP (I didn't try again ever since, my "client" fleet was not completely replaced yet).
Probably the most universal configuration would be to set authentication-types=wpa2-psk,wpa3-psk connect-priority=0/1 dh-groups=19,20,21 encryption=ccmp,ccmp-256 ft=yes ft-over-ds=yes in security settings.
