Best Wifi Extender?

Ive just got the Ring video Doorbell 3. I made it sure it worked before putting by our front door - it also came with a chime, which works.
However, now the camera is in place outside, it doesnt work, stating it is offline! I suspect this is due to range, and signal being blocked by several walls and a floor. Is there a recommended wifi extender, or are there features i need to make sure one has in order to work?

Hi @Chrisg46. I’ve recently purchased the Ring Alarm Pro with a built in Eero and paired it with a few Eero Beacons. In my 3,900 sq/ft. house, I have no issues with connectivity. For me, the Eero system has really been a great addition to not only my Ring products, but all of my WiFi connected devices.
