How to use the wifi connection test
- 1
Connect to the WiFi network you want to evaluate.
- 2
Run the browser request stability check.
- 3
Compare latency and stability in different locations without treating them as exact signal strength.
WiFi Connection Test
Check the current WiFi or network connection using browser-visible latency, stability, and online status. Browsers do not reliably expose WiFi RSSI or dBm.

Understanding your wifi result
Check the current WiFi or network connection using browser-visible latency, stability, and online status. Browsers do not reliably expose WiFi RSSI or dBm.
The result records only values the browser measured or checks you explicitly confirmed. Unsupported and unavailable values are labeled honestly rather than estimated or invented.
Troubleshooting
The test cannot show signal bars
Standard browsers do not reliably provide RSSI or dBm, so TestMyDevice does not invent them.
Connection feels unstable
Move closer to the access point, reduce interference, and compare a wired connection.
Latency stays high
Pause other traffic and test at a different time or against another service.
WiFi Connection Test FAQ
Can this show exact WiFi signal strength?
No. Web browsers generally do not expose reliable RSSI or dBm values.
What does this test instead?
It measures browser-visible request latency, jitter, success rate, and online status.
