- 5Fast speed tests but laggy internet: packet loss blamedβSpeedtest zeigt volle Mbit/s, aber Seiten laden stockend und Videocalls reiΓen ab? Dann lohnt ein Blick auf die Anfragen
German-language tech discussions point out that a speed test showing full megabits does not guarantee a smooth connection. Slow-loading pages and dropped video calls can stem from request or packet losses rather than low throughput, so a nominally fast line can still feel sluggish in everyday use. Users are being advised to measure losses alongside raw bandwidth to diagnose the real cause of poor connections.
