Troubleshooting
The WiFi name shows as unknown
Android hides the network name from apps without location permission. Allow location for WiFi Speed Meter in Android Settings, and make sure location is switched on for the phone.
My result is much lower than my plan
Test again close to the router, on the 5 GHz band if your router has one, with other devices idle and any VPN switched off. Read the Connection Doctor card under the result: it points to the most likely cause.
The test stops or fails
Check that you are online, then try again. If a regional server is selected, switch back to Auto. Firewalls on some office or school networks block test servers.
Scheduled tests do not run
Allow notifications and exclude the app from battery optimisation; some phones stop background work aggressively.
I bought Pro but still see ads
Open the Pro screen and tap Restore purchase, using the same Google account you paid with. If that does not help, email us with your Google Play order number (it starts with GPA).
How do I cancel my subscription?
Open Google Play, tap your profile picture, then Payments & subscriptions > Subscriptions, and choose WiFi Speed Meter.
How do I delete my data?
Use Reset local data in the app, or uninstall it. We do not hold your results on any server. See the Privacy Policy for data handled by our providers.
