iPhone w/iOS 17.1.2 says my WIFI network is WEP but my router says it's WPA2-PSK (AES)

Hello -- My iPhone says my WiFi network has Weak Security; when I tap on the i in the circle it says "WEP is not considered secure" and to "configure the router to use WPA2 (AES) or WPA3 security type" When I access my router, it shows that both the 2.4Ghz and 5Ghz networks are WPA2-PSK (AES). Anyone have any ideas here? Thanks.
