WPA Weak Security Warning

Ever since updating to Big Sur 11.6 strange issue occurring. Connecting to WiFi I get the warning of weak security that the connection is WPA and I should upgrade to WPA2 or WPA3. Here's the catch. Checking my router, it's always been on WPA2 and nothing has changed. Furthermore, connecting to my Guest Network on the same router doesn't present this warning. Any suggestions?

Mac mini, macOS 11.6

Is the router security set to WPA2 AES? TKIP or Auto instead of AES in the encryption setting on the router will result in the weak security warning by Apple.

Try restarting the router.

Yes. WPA2 AES. Don’t understand why I’m getting this warning on the main network but the Guest network which is the same with a different password isn’t giving me that warning from my MacMini.
