To check the Wi-Fi GHz on an iPhone, go to Settings > Wi-Fi and look for the network name next to 'PHY MODE'. The number after 802.11 will indicate the GHz of your connection (for example, a PHY MODE of 802.11ac indicates that your connection is 5GHz).

  1. Go to the Settings app
  2. Tap Wi-Fi
  3. View the name of your network

Our takeaway

In conclusion, while checking the GHz of your iPhone’s WiFi may seem complicated at first, it really is an easy process. Not only will you know how fast your connection should be, but understanding the technology behind it can make all the difference in using your device more efficiently. So the next time you are having difficulty connecting to a network or streaming content, take a few moments to check out whatGHz your iPhone’s WiFi is currently running and get back online in no time!


1. What is the difference between 2.4 and 5 GHz WiFi?

The primary difference between 2.4GHz and 5GHz wifi networks is the signal range they offer, with 2.4GHz offering a much greater coverage area than 5Ghz signals. Additionally, because of their longer range and greater penetration through walls and other obstacles, 2.4Ghz networks tend to be slower but are better for penetrating obstructions such as thick walls.

2. How do I know if my iPhone supports dual band wireless technology?

You can check to see if your device supports dual-band Wi-Fi by going to Settings > Wi-Fi and looking for the 5GHz network option. If it’s available, you have a dual-band capable device.

Can I switch between different WiFi Ghz networks on my iPhone?

Yes, you can switch between different 2.4 Ghz and 5 Ghz networks with your iPhone if it supports dual band wireless technology. To check which frequency your device is connected to, go to Settings > Wi-Fi and the name of the network will be displayed in the list of available networks.


Are there any security concerns with using a higher frequency WiFi network?

Yes, there are possible security concerns with using higher frequency networks, such as the 5 GHz range. First of all, because the signal has less distance to travel, it may be easier for someone to intercept your signal and access your information. Additionally, the 5 GHz band is more prone to interference from other wireless devices operating on the same spectrum than 2.4 GHz networks. As such, it is important to take proper measures to secure your connection when using a higher frequency network.

Does having a lower frequency WiFi network help speed up speeds on my iPhone?

No, having a lower frequency WiFi network does not necessarily result in faster speeds. The performance of the network depends on many factors such as the number of devices using the same network, and distance from the router. Additionally, some networks favor higher-frequency channels and may be faster for certain specific connections.
