My note 8 has stopped switching to wifi calling while in my house with poor signal. Used to switch onto wifi, now will not even when I try to force it in airplane mode.
Seeing that you are speaking about your home coverage, I can see why you are inquiring about your signal. Can you tell me about when it started? What software are you currently on? https://www.verizon.com/support/knowledge-base-227433/ Are others having trouble connecting to your Wi-Fi?
