A moving device can switch between access points as signal conditions change. The handover may briefly affect delivery, depending on the network and client. A stationary television problem should not automatically be diagnosed as roaming.
Reproduce the movement
Compare playback while stationary with playback during the route between rooms. Keep the same app and source. If only movement triggers the issue, inspect access-point coverage and handover behaviour rather than changing account credentials.
Check coverage overlap
An access point placed too far from its neighbour may leave a weak transition area. Mesh placement and backhaul quality both matter. Follow the system's guidance rather than adding nodes without considering their upstream connection.
Avoid unsupported roaming tweaks
Fast-roaming features and client support vary. A setting suited to one device may not suit another. Change one supported option at a time, retain the original configuration and compare all important household devices.
