Room-by-room method
- Test near the router for a baseline.
- Test in the room where Wi-Fi feels bad.
- Repeat in the places used for streaming, work, and gaming.
- Run tests again during busy hours.
Wi-Fi Speed Test
Wi-Fi speed test: check every room, not just the router
If Wi-Fi feels slow, test where the problem actually happens. A useful Wi-Fi speed test compares download speed, upload speed, ping, jitter, and packet loss near the router and in each room.
Quick answer
A Wi-Fi speed test should answer two questions: is the internet plan slow everywhere, or is Wi-Fi weak only in certain rooms? Testing only beside the router can hide the real problem.
What to check in a Wi-Fi speed test
| Metric | Why It Matters |
|---|---|
| Download speed | Shows how fast pages, videos, and files can load. |
| Upload speed | Affects video calls, cloud backup, and sending files. |
| Ping | Shows delay in games, calls, and remote apps. |
| Jitter | Shows unstable delay that can create random stutter. |
| Packet loss | Shows dropped data that can break calls or games. |
How to read the pattern
- Only one room is slow: likely coverage or interference.
- Every room is slow: plan, modem, router, or ISP may matter.
- Speed is fine but calls break: check jitter and packet loss.
- Evening tests are worse: congestion may be the pattern.

LizSpeedTest checks speed, ping, jitter, and packet loss so you can compare rooms and see whether slow Wi-Fi is really a coverage, congestion, or stability problem.
