Generally, your iPhone connects to the Wi-Fi network available, and it's your router that determines whether it's 2.4 GHz or 5 GHz. Your iPhone itself doesn't choose which to use; it connects to whichever network you've selected if both are available. To determine which network your iPhone is connected to, follow these steps:
How to Check Your Wi-Fi Band on Your iPhone
There isn't a direct way within the iPhone's built-in settings to definitively see the GHz band of your current Wi-Fi connection. However, here are the most common ways to find out:
1. Check Your Wi-Fi Router's Network Names
-
Most modern Wi-Fi routers broadcast two separate networks: one on the 2.4 GHz band and one on the 5 GHz band.
-
Look at the network names (SSIDs). Often, the 5 GHz network will have "5G" or "5GHz" appended to the name (e.g., "MyWiFi" and "MyWiFi 5G").
- Example: If you see "HomeWiFi" and "HomeWiFi-5G" in your Wi-Fi settings, the one with "5G" is the 5 GHz network. If your iPhone is connected to "HomeWiFi-5G," it's on the 5 GHz band.
2. Use a Wi-Fi Analyzer App
- Download a Wi-Fi analyzer app from the App Store. There are several free and paid options. Some popular choices include:
- WiFi Analyzer
- Network Analyzer
- Open the app and scan for nearby networks. These apps display detailed information about each network, including the frequency band (2.4 GHz or 5 GHz).
3. Check Your Router's Settings
- Access your router's configuration page through a web browser (usually by typing its IP address into the address bar – check your router's manual or the manufacturer's website for instructions).
- Log in using your router's username and password.
- Look for the Wi-Fi settings. The configuration page will typically show you which networks are active (2.4 GHz and 5 GHz) and which devices are connected to each network. This is the most definitive method.
In Summary: Your iPhone connects to available Wi-Fi networks. To determine if it's using 2.4 GHz or 5 GHz, examine your router's network names, use a Wi-Fi analyzer app, or check your router's settings.
