Hey @Edwin92677! Thanks for confirming all of these details. The network signal and speed certainly sounds sufficient for intended operation of your Ring devices. Something I often recommend for a home using multiple Chimes, is to try your best to locate these Chimes centrally between the router and Camera/ Doorbell device. If you are able to obtain a linear line of sight between each Chime, the router, and the Ring device, this will also help for a smooth and synchronized delivery of notification tones.
Keep in mind, these communications are being performed over wifi in which radio signals can certainly travel over the air at different rates of speed, depending on numerous factors. If the above recommendations do not improve notification timing, the processing and multi-communication abilities of your router is always worth considering as well. I hope this helps!
