  • Fiber connections: symmetric upload and download, lowest latency, and the most stable performance under peak load — ideal for remote work and cloud workflows
  • Cable, DSL, and fixed-wireless: usually fast download but slower upload, and more likely to dip 20–40% during 7–10 PM peak hours on shared local segments
  • Benchmark against your plan: a healthy wired result should land within 80–95% of your advertised speed; anything consistently lower is worth flagging with your ISP

Speed Test Tips for São Luís 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
