Cannot connect chime to new wifi

i have changed wifi i connected doorbell and two cameras to new wifi i have tried to connect chime to new wifi by pressing button for 5 seconds to start a blue flashing. i could not get it to flash. so i then removed the chime device and tried to set it up new. when i scanned the mac id during the setup process the ring app thought i was connecting a door bell 2. hence i could not set up the chime again. please help
