Capture download and upload rates, latency, and packet loss; a result above 90 Mbps download and less than 1 % loss typically reflects a solid connection. Proceed to Wi‑Fi evaluation. Position the client where it is normally used, repeat the iPerf3 test, and compare the numbers to the wired baseline. If throughput falls more than 30 % or latency exceeds 20 ms, https://wiki.lafabriquedelalogistique.fr/Discussion_utilisateur:Qzinoyefuw investigate channel congestion, router placement, or antenna orientation. Log stability with continuous ping tests. Set a 1‑second interval to a reliable server (e.g., 8.8.8.8) and record round‑trip times for five minutes. Look for spikes over 50 ms or occasional timeouts; these patterns often point to intermittent interference. Combine the data in a simple spreadsheet: column A for test type, column B for average speed, column C for latency, column D for packet loss. Use conditional formatting to highlight values that exceed your thresholds, then schedule repeat tests during peak and off‑peak hours to spot time‑of‑day variations.
