The default gateway is the device that normally forwards local traffic toward other networks. A repeatable problem reaching it can point to the home connection rather than the remote media source. Use a diagnostic method supported by the device.
Keep the test modest
If the gateway answers ordinary probes, compare several responses over a reasonable interval. Some equipment limits diagnostic replies, so lack of an answer is not conclusive by itself. Avoid overwhelming a shared router with aggressive tests.
Compare wired and wireless
A clean wired result with unstable wireless behaviour narrows attention toward the local radio path. Keep the device and test method consistent. Moving to another computer also changes the client and should be noted.
Combine with playback evidence
Record whether the stream paused at the same time as the local problem. A clean gateway test does not prove the entire internet route is healthy; it only addresses part of the path. Report the limited finding accurately.
