WiFi Speed Test

Measure download, upload, and latency on the Wi‑Fi (or other) connection this device is using right now.

A Wi‑Fi speed test measures internet throughput on the current connection. It cannot read signal strength or radio quality from your router.

How this test measures your connection

Node: local-dev

Ping here is HTTP round-trip time after one warmup sample, not ICMP. Speeds use decimal Mbps from bytes and elapsed time.

What does this tool measure?

A WiFi speed test measures internet throughput on the connection this device is using. It cannot read signal strength, channel congestion, or the radio rate reported by your router.

How do I use it?

  1. Stay connected to the Wi-Fi network you want to test.
  2. Pause large transfers on this device and run the test.
  3. Repeat near the router, then in the room where the problem occurs.
  4. Compare with Ethernet when available to separate Wi-Fi limits from service limits.

How should I read the result?

Download and upload show delivered internet throughput. HTTP ping and jitter show responsiveness and consistency to this node. A large Wi-Fi-versus-Ethernet gap usually points to the local wireless path.

What are the technical limits?

The browser only sees the active internet path. It does not know the access point, band, channel, signal level, or negotiated Wi-Fi link rate.

Frequently asked questions

Why is Wi-Fi slower than Ethernet?

Distance, walls, interference, shared airtime, older client hardware, and router capacity can all reduce Wi-Fi throughput.

Should I test on 2.4 GHz or 5 GHz?

Test the band you normally use. In general, 2.4 GHz reaches farther while 5 GHz can provide more capacity at shorter range, but the actual result depends on the equipment and environment.
