WiFi Network Still Shows After Router Replacment

[Pierre535]

I replaced my TP-Link router with an Asus router and set up new network names. For some reason, the old Network still shows up as being selectable. This even after several OS updates. Shows up on my Mac Studio, MacBook Air M3, iPad Pro M4, iPhone 16 Pro. and new iPad mini. After upgrading to iPhone 16, i was hoping it would go away, but nope. Any suggestions?

Any WiFi repeater/extender still broadcasting old SSID?

Selectable, as in list, but not able to connect, right?
The SSID names are kept somewhere. Even Amazon wants to, to make it easy to reconnect.
Tried deleting on Mac in Network options?

Thanks, Extender plugged in and hidden out of sight.
