Questions Re: Ring Base Station, Extender, Signal strength

I just switched to Ring from another alarm company. I love the cameras because they all connect to my Eero mesh WIFI which is really strong. I have 4 cameras and 3 ring doorbells all connected to my Wifi. I have concerns about the Base Station and sensors. My house is about 50 feet long. I also purchased an Extender which I have installed about 25 feet from the base station, central in my home. Some of the sensors on windows and doors say they have a "weak connection to your Base Station." That's curious. Shouldn't they be connecting to the Extender? Pretty much the only thing with a strong connection to the Base Station are the sensors in the room with the Base Station. What's a good way of fixing things?Could I have a faulty Extender? Can I "Reboot Base Station" and is that safe- would that make things reconnect? "Reboot Base Station" doesn't get rid of any settings, right? I tried "Retry Connection" on some of the weak devices but that didn't avail anything. Should I Remove Devices and re-add them? Base station and Extender for my 50 foot home should be plenty strong to get all devices connected really good. Any advice?
