I’m using OpenWrt 19.07.9 on my router and I’ve noticed that recent versions default to WPA2/WPA3 mixed mode for encryption. Unfortunately, some of my legacy devices fail to connect when using mixed mode.
I need a way to enable WPA2-PSK as a standalone encryption option (without forcing WPA3 compatibility). However, in the web interface, the only available options seem to be WPA2/WPA3 mixed mode or WPA3-SAE.
Is there a package I can install that restores the ability to select WPA2-PSK only? Or is there a manual configuration workaround to achieve this on OpenWrt 19.07.9?
This is not true, at least for official OpenWrt firmware. The actual default is no encryption (but wifi is also disabled and the SSID name is OpenWrt).
All recent versions offer WPA2 (psk2), WPA3 (sae), and WPA2/WPA3 mixed mode (sae-mixed). These options are available by default -- simply select the one you want to use.
Yes, this is common. That is why the recommendation is to use WPA2 or WPA3 and not mixed-mode.
No additional packages are required.
19.07 is EOL and unsupported. You should be running a more recent version (23.05 or 24.10).
