How to change Wi-Fi security of Time Capsule router

My iPhone Wi-Fi Settings alerted me to weak security for my router. It says upgrade to WPA3 from WPA2 Personal.

I searched for how to do this with Air Port Utility. The only option shown is WPA2. In the graphic window under Edit I see an update button but I didn't click it because I made no changes. Correct, or is that how to update security options?

MyTime Capsule is 2016 and has 802.11ac and others. Apple Support says WPA3 usually needs 802.11ax, which this TC doesn't spec.

The firmware for my TC is up to date. Is there another way to install WPA3 on this router? Do I need to replace the router?

Good luck! If you do choose one of the mesh systems in the link above, we have helped other users set up their Time Capsules with each one of these systems, so post back if you decide on one of these systems and you want to continue using the Time Capsule for backups.
