Use a reputable speed test website or app (e.g., Ookla Speedtest, Fast.com, Google speed test)
Close other apps or downloads that could affect results
Connect using the device you want to test (Wi‑Fi or Ethernet)
If testing Wi‑Fi, stay close to the router and avoid moving during the test
Run the test at least 3 times
Record download speed, upload speed, ping/latency, and jitter (if shown)
If results vary, test at different times of day
Test both Wi‑Fi and Ethernet (if available) for comparison
Restart the modem/router if you suspect a temporary issue
For Wi‑Fi, test on the same frequency/band (2.4 GHz vs 5 GHz) if your router supports it
Use the same server/region selection if the tool allows it
Confirm the device isn’t using VPN or proxy during the test
Check for background usage (cloud sync, streaming, updates) and rerun if needed
Compare results against your plan’s advertised speeds
If speeds are consistently low, test again from another device on the same network
If possible, test from a wired connection to isolate router/Wi‑Fi issues
Document timestamps, device, connection type, and results for troubleshooting
