The model number is not available from the drop down menu.  The last discussion on support for the AC5400x V1 on support for WPA3 was around March 2021.  I was wondering if any progress has been made in that respect?  I am very happy with my product, but it would seem that this model is left behind when it comes to WPA3.  Encryption is very important these days so it would make sense to provide it.  As indicated in the previous discussion, brand loyalty would certainly benefit from such an upgrade.  If I have missed the firmware update, please let me know!  Thanks.
