  • Fiber-to-the-home: symmetric by design, lowest jitter, and the most reliable under real-world load
  • Coax, copper, and fixed-wireless: competitive download figures, but upload and peak-time performance vary by neighborhood and time of day
  • What "good" looks like: a wired test in the 80–95% range of your advertised speed, with upload in the same ballpark your plan promises

Speed Test Tips for Dortmund Residents

  • Wired baseline first: plug directly into the router with a CAT5e/CAT6 cable before blaming your ISP — Wi-Fi overhead hides the true line speed
  • Test at two times of day: once mid-morning and once between 7–10 PM to see how shared infrastructure behaves under load
  • Look past download: upload, ping, and jitter predict video-call and cloud-backup quality far better than a big download number
  • Worst-case, not average: run 3–5 back-to-back tests and record the lowest result — that's the number your real-time apps actually hit
