3 Easy Ways to Check Your WiFi GHz on an iPhone

Before we begin, it’s important to note that these steps will help you identify which frequency your iPhone is currently using to connect to a WiFi network.

Step 1: Open Settings

Open the “Settings” app on your iPhone.

Opening the Settings app is the gateway to all the customizations and adjustments you can make on your iPhone. In this context, it’s the first step to access your WiFi settings and check the GHz frequency.

Step 2: Tap WiFi

Tap on the “WiFi” option within Settings.

By tapping the WiFi option, you’re directing your iPhone to show you all available WiFi networks and the one you’re currently connected to. It’s the second step in our quest to find out the GHz frequency of your WiFi.

Step 3: View Network Details

Select the network you’re connected to, then tap the “i” icon to view details and see the GHz frequency.

When you select your network and tap the “i”, a new screen will display various details about your WiFi connection. Here you’ll find the information about the GHz frequency of the WiFi you’re connected to.


Improved ConnectivityKnowing the frequency can help you choose a less congested band, leading to better WiFi performance.
TroubleshootingIdentifying the GHz can help solve connectivity issues, as some devices perform better on different frequencies.
Optimized Device PerformanceUsing the optimal frequency for your iPhone can enhance overall device performance and internet speed.


Limited by RouterYou can only access the frequencies your router supports, which might not include both 2.4 GHz and 5 GHz.
Device CompatibilityOlder iPhone models might not be compatible with 5 GHz, limiting your options to 2.4 GHz.
InterferenceOther household devices can cause interference, especially on the 2.4 GHz frequency, which could affect connectivity.

Additional Information

When checking your WiFi GHz on an iPhone, it’s also helpful to understand the difference between the 2.4 GHz and 5 GHz frequencies. The 2.4 GHz band is more common and has a longer range but is also more prone to interference from other devices like microwaves or cordless phones. On the other hand, the 5 GHz band offers faster speeds and is less congested but has a shorter range.

Knowing which frequency your iPhone is using can be particularly useful if you’re experiencing a slow or unstable connection. If your router supports dual-band connectivity, you can choose to switch between the frequencies based on your current needs – like using 5 GHz for high-speed gaming or video streaming and 2.4 GHz for browsing when further away from the router. Always keep in mind that the prompt keyword “check your WiFi GHz on an iPhone” is an easy and vital skill to master for optimizing your wireless network usage.


  1. Open the “Settings” app on your iPhone.
  2. Tap on the “WiFi” option within Settings.
