Not capturing all motion - wifi conneciton?

My ring doorbell 3 is so bad at capturing motion, that it's basically not even worth using (I have it set properly in the settings, but for example, I'll see the mailman walking away, but not approach. Or if a car pulls up the driveway fast enough, the camera doesn't detect it at all.) Figuring it was the wifi conneciton causing the issue, I bought a wifi extender ([https://www.amazon.com/gp/product/B00R92CL5E/ref=ppx\_yo\_dt\_b\_asin\_title\_o02\_s00?ie=UTF8&psc=1) ](https://www.amazon.com/gp/product/B00R92CL5E/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1), and the app said the connection was good. The doorbell is near the front door, and it's a standard brick Ranch 1200 sq ft house. The wifi extender (2.4ghz) is directly on the wall (the same wall behind the door bell) right when you enter the front door. The rouer is in the basement. My question: do I simply have the wrong kind of wifi extender? Is it the connection causing the motion not to go off properly? Or could it be a faulty unit from ring? Is there any hope? I have not heard back from ring customer support in at least 2 months. Thanks a ton in advance!
