There's not really such thing as a cloned wifi network conceptually: If you set up a new access point using the same SSID and encryption settings, you didn't clone a network – you just extended it by one more access point/location where it's available!

A Wi-Fi network is the abstract concept of "all access points using the same name and passphrase", not an individual instance of an access point.

If you connect the two access points (e.g. using wired Ethernet), clients can actually roam between the two fairly seamlessly without any other setup required, and this even works across brands!
