1. Define the scope
- Does it affect one source or everything?
- Does it happen on one device or multiple devices?
- Does it happen all day or mainly at peak hours?
2. Test the home network
Pause large downloads, test near the router, and compare Wi-Fi with Ethernet if available. A speed test can look healthy while packet loss or an unstable wireless signal causes interruptions.
3. Check the device
Restart it, close background apps, confirm free storage, and install current operating-system updates. Higher-resolution media can exceed the decoding capability of older hardware.
4. Check the player
Clear temporary cache where the platform allows it. Start with default playback settings, then test hardware decoding or a modest buffer change one at a time.
5. Check account and source behavior
Confirm the simultaneous connection limit. If one source fails across multiple devices while others work, report that source rather than rebuilding your entire setup.
About VPNs
A VPN cannot create bandwidth and can make performance worse. It may change routing in limited cases, but it should not be presented as a guaranteed buffering fix.
