• 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 Yokohama 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
