Dear all, I opened another ticket on OpenWRT forum.
In short, some clients like my laptop do not support WPA3 and/or WPA2 with PMF (frame protection mode). This depends on wireless chipset and firmware. In Network-Manager, when connecting to a WPA2/WPA3 mixed mode SSID, we should be able to select WPA2-PSK or WPA3-SAE authentication and enable or disable frame protection. If logon fails, there is a risk to get banned. Read: https://forum.openwrt.org/t/wpa3-fails-to-connect-then-banned-from-ap-during-hours/70914/14 IMHO, this bug should be escalated to Network-Manager team or OpenWRT team, as this is not a Debian issue. Feel free to close the issue. A lot of wireless cards using WPA3 or WPA2/WPA3 mixed mode should be impacted, so you may also leave the ticket open till the dust comes down. Kind regards
