Setup help battery doorbell

The home base and the doorbell are in direct sight but doorbell keeps going offline. Ideas why it may keep falling offline? And Do I have to reset it to get it back online every time? Thanks!

A couple things come to mind:

  1. Do you have a lot of wireless devices between the home base and the doorbell?
  2. What material is the door/wall? (I found that metal doors interfere a lot with the wireless 2.4 modes
  3. Are you able to connect the home base via ethernet to test if the wifi module is bad?
