Packet loss means some packets did not reach a measurement destination or did not receive a response. It can disrupt real-time media, but a diagnostic tool's result needs context: some network devices limit replies while still forwarding traffic.
Test an end destination
Compare repeated measurements to a destination expected to answer. A middle router showing missing replies is not conclusive if later hops respond normally. Do not treat every warning colour in a route trace as proof of a broken link.
Compare local and internet paths
If supported, test the local gateway separately from an internet destination. Loss to the gateway suggests a local connection problem. A clean local path with wider failures points further outward, though the chosen test still may not follow the media route.
Keep the report proportional
Record the test duration, wired or wireless connection and whether playback failed at the same time. Tiny samples can exaggerate normal variation. Share the summary with the relevant support team rather than making repeated disruptive router changes.
