I have a Deco M9 Plus with current firmware, and all works well except the router doesn't retain the WiFi security setting WPA2-PSK (AES) after a power cycle. I turn my router off at night, and when I turn it back on in the morning, it always reverts to the WPA2-PSK (AES) + WPA-PSK (TKIP) setting. When I change it back to WPA2-PSK (AES) I always tap Save.

Would appreciate any ideas on how to permanently change the default WiFi security setting.

Thanks

Mark
