How to Test WiFi Signal Strength on iPhone?

If Netspot for iOS didn’t fully solve your problem, another useful method to test your WiFi signal strength is by using the built-in Apple Field Test Mode. It’s a bit more technical, but it doesn’t require downloading any apps.

  1. Activate Field Test Mode: Open your iPhone and dial *3001#12345#* and hit call. This will open up the Field Test Mode.
  2. Check Signal: Look for the WiFi menu or option. Keep in mind this interface is not the most user-friendly and some steps can vary based on the iOS version.
  3. Detailed Info: You can find detailed information about the WiFi networks around you, including signal strength measured in dBm. The closer the number is to 0, the better. Typically, anything from -30 to -70 dBm is good.

However, this method won’t give you the same visual representation as something like Netspot for iOS. Also, responsibility for interpreting the data correctly falls onto you, which may be less intuitive than using a dedicated app.

Sometimes, a signal issue might not be strictly about strength. Issues like channel congestion or interference from other devices are common culprits. While Netspot helps you identify crowded channels, you can manually tweak your router settings by:

  1. Router Settings: Log into your router’s admin panel (usually 192.168.1.1 or 192.168.0.1 in your web browser).
  2. Change Channels: Look for wireless settings and try switching to a less crowded channel.
  3. Upgrades: If your router is on the older side, moving to a new one could offer better signal strength and newer tech like WiFi 5 or 6.

Another possible fix if you’re sure your network is fine would be to reset your iPhone’s network settings as @suenodelbosque mentioned. Just don’t forget this erases all WiFi passwords, so have them handy.

For those looking for more comprehensive troubleshooting tools, considering other apps like ‘WiFi SweetSpots’ or even Apple’s own diagnostics if you’re in contact with support could be beneficial.

In my experience, where hardware limitations are a concern, pairing with WiFi extenders or mesh networks significantly improves coverage in larger or more obstructed spaces.

For more detailed WiFi diagnostics and optimization, be sure to check the Netspot Official website for additional resources and guides.

Hope this adds another layer of insight to your WiFi troubleshooting journey!
