I have the same issue. My POD drops the speed dramatically and also does not provide a stable connection. Upload speed of below 1mbps frequently which then kills my zoom calls. If I move to the room with the router, the speeds are totally fine. The router is the worst I have ever experienced - doesn't give you a good speed anywhere except directly in line of sight.
