doorbell power issues

Anybody have a solution to the doorbell going off line after a few days issues.  I have replaced the transformer for the chime, installed the door chime connector kit, and have a dedicated wifi channel for the doorbell.  Same old issue.  Works fine for a few days and then does offline.  I have to completely reinstall and then it works fine for another few days.  I'm pretty sure the issue is that it does not get enough power through the chime to powered up.  Other SimpliSafe cameras work perfectly.  Any help is appreciated.
