My iPhone11 WiFi calls almost always has very bad connections from my home. Almost no connectivity to network since cell towers were moved so I have to use Wifi. Wifi signal shows as very strong on my phone. Often both parties are only hearing every other word. Voices are sometimes distorted and dropped calls are a problem.
How can I narrow down if this is a problem with my phone, the WiFi Router or the Verizon network somehow? I’m not sure who to call to fix my problem until I can figure out whose problem it is!
