How to Check WiFi Band on iPhone

Are you wondering whether your iPhone is connected to a router with a 2.4GHz or 5GHz band? Although the iPhone does not have a built-in feature to determine the network connection band, you can still apply some simple ways to determine the GHz number of the router in your home. This article will help you know how to check the Wi-Fi band on iPhone and a simple way to connect to the band you want.

See band name

See the name of the Wi-Fi network you're connecting to. If you're connected to a dual-band Wi-Fi router, you can check which band you're connecting to based on the name of the access point on your iPhone. How to find information as follows:

Open Control Center by swiping the screen down from the top right corner (for iPhones without a Home button) or swiping the screen up from the bottom (for iPhones with a Home button).

Touch and hold the Wi-Fi icon in the upper left corner.

The name of the Wi-Fi access point appears below "Wi-Fi" on the left. If you see "2.4GHz" or "5GHz" here, that is the band number you are connecting to.

If this is a home connection and the band is not displayed this way, you can refer to how to change the band on the Wi-Fi router.

Find the router's IP address. If you have a dual-band router, the simplest way to know which band your phone is connecting to is to enter the SSID number or network name of each band. First, you need to find the router's IP address. On iPhone, you can find the IP address in the following way:

Access Settings .

Open Wi-Fi .

Click the Information button next to the router's network name.

Swipe down until you see the number next to Router in the IPV4 Address section . The router number will look like 168.123.1.234.

Log in with your router's username and password. When the router's website displays, you will be asked to log in. If you don't know the username and password, you can usually find that information on the router's sticker.

The default username for most routers is 'Admin'.

Look for a setting that allows you to create separate SSIDs for each band. Every router is different, so there is no one way to do this. You need to refer to the router's user manual or visit the support website to find information on setting up separate network names for each band. In most cases, these settings appear under the Advanced Settings tab or similar.

If your router does not automatically allow you to create unique names for each band, you need to enable the setting or check the box to enable this feature.

Give each frequency band a separate name. Thus, you can easily know which frequency band your phone is connecting to. For example, you name the 2.4GHz network 'Home_Network-2.4GHz' and the 5GHz network 'Home_Network-5GHz'.

Although this is the simplest way to help you know which band your iPhone is connected to, you should note that Apple does not encourage users to name individual bands. Giving both bands the same name allows your phone to automatically switch between bands so you can always connect to the strongest signal.

See channel information for band specifications. Under the name of each network, you will see various information. To know if the network has the 5GHz or 2.4GHz band, you need to look at the number next to the word Channel . If you are in the US, networks on channels 1-11 are on the 2.4 GHz band, while channels with numbers greater than 11 are on the 5GHz band.

For example, channel 6 is in the 2.4GHz band, while channel 40 is in the 5GHz band.

If you live outside the US, the channel number will be different. For example, in most countries, channels 1-13 are in the 2.4GHz band, while channels with larger numbers are in the 5GHz band. In Japan, channel 14 has the 2.4GHz band.

If you use a dual-band router and both have the same name, the information section will show both bands as two different networks with the same name.
