How to Check Your WiFi GHz on iPhone?

2.4 GHz vs. 5 GHz WiFi: Which One is Best for Your iPhone?

Your iPhone can connect to WiFi networks that operate on two different frequencies: 2.4 GHz and 5 GHz. Each frequency has its advantages and disadvantages.

In this article, we will guide you on how to check which WiFi GHz your iPhone is connected to and explore the benefits and limitations of both frequencies, empowering you to make an informed decision.

How to Check Your WiFi GHz on iPhone

If you’re unsure which WiFi frequency your iPhone is currently using, follow these simple steps to find out:

  1. Open the Settings App: Locate and tap on the Settings app on your iPhone’s home screen.
  2. Access Wi-Fi Settings: Within the Settings menu, tap on Wi-Fi, which is usually located near the top of the list.
  3. Identify the Frequency: Look for the name of your connected WiFi network. Next to it, you should see either the label “2.4 GHz” or “5 GHz,” indicating the frequency your iPhone is currently connected to.

Pros and Cons of Each WiFi Frequency

Here are some of the pros and cons of each WiFi frequency:

Pros and Cons of 2.4 GHz Frequency

The 2.4 GHz frequency is the older and more widely used option. It comes with both advantages and disadvantages:


  • Wider Availability: Many routers and devices support the 2.4 GHz frequency, making it readily accessible.
  • Better Signal Penetration: The lower frequency allows the signal to penetrate walls and obstacles more effectively, ensuring a stronger connection in areas with interference.


  • Slower Speeds: The 2.4 GHz frequency offers slower data transfer rates compared to the 5 GHz frequency, especially in areas with heavy network traffic.
  • More Crowded: Due to its popularity, the 2.4 GHz frequency is more congested, leading to potential signal interference in densely populated areas.

Pros and Cons of 5 GHz Frequency

The 5 GHz frequency is the newer option and boasts some distinct advantages and disadvantages:


  • Faster Speeds: With higher data transfer rates, the 5 GHz frequency delivers faster internet speeds, ideal for bandwidth-intensive activities like streaming and online gaming.
  • Less Crowded: The 5 GHz band is less congested, resulting in reduced interference and potentially more stable connections.


  • Limited Availability: Not all devices and routers support the 5 GHz frequency, which might limit your connectivity options.
  • Shorter Range: The higher frequency has a shorter range, making it less suitable for covering large areas compared to the 2.4 GHz frequency.

Which WiFi Frequency is Best for You?

The decision between 2.4 GHz and 5 GHz ultimately depends on your specific requirements and circumstances. Consider the following factors:

  • Speed vs. Coverage: If you prioritize faster speeds and have devices compatible with 5 GHz, opt for this frequency. However, if you need a reliable connection across a larger area or in places with many obstructions, the 2.4 GHz frequency might be more suitable.
  • Device Compatibility: Check if all your devices support 5 GHz. If not, a dual-band WiFi router that operates on both frequencies might be the best compromise.
  • Network Environment: Analyze your surroundings for potential interference from other wireless networks and electronic devices. The 5 GHz frequency could offer a more stable connection in crowded areas.

Many modern routers support dual-band WiFi, allowing you to use both 2.4 GHz and 5 GHz frequencies simultaneously. This feature enables your iPhone to automatically switch to the best frequency based on the network conditions. To take advantage of this functionality, ensure your router’s settings are correctly configured for dual-band operation.


Understanding the WiFi GHz your iPhone is connected to is crucial for optimizing your internet experience. The 2.4 GHz frequency offers wider availability and better signal penetration, while the 5 GHz frequency provides faster speeds and reduced congestion. Assess your needs, device compatibility, and network environment to determine which frequency suits you best.

Additionally, consider using dual-band WiFi for enhanced flexibility and seamless connectivity. By making an informed choice, you can enjoy a smoother online experience tailored to your requirements.
