How to extend the wi-fi range for the Floodlights?

I just moved into a new home that has the - Ring Battery Doorbell Plus, 2 Chime Pros, 2 Floodlight Cam Wired Pros.My problem is that the Wi Fi Router is on the far side of the house (can’t be moved), it’s close enough to the Doorbell, one of the Floodlights and one of the Chimes, but too far for the other floodlight and I want one of the Chimes on the other side too.I looked at the Ring Extender, but it says it’s only for the Alarm System. (may get this later).So, what I need is to extend the Wi Fi, I think. How do I do this? Thanks
