How to determine the Wi-Fi frequency on an iPhone: 2.4 GHz or 5 GHz?

• TP-Link: Wireless Mode → Wireless Mode Statistics.
• ASUS: Network Map → Clients.
• Keenetic: Devices → Device List.
• Find yours in the list iPhone (by name or MAC address) - the range will be indicated next to it (2.4G or 5G).

⚠️ Note: If there is no speaker with the frequency in the list of devices, check the section Wireless network settings - some routers show the range only there, provided that the networks are separated (different SSIDs for 2.4 and 5 GHz).

Make sure that the 2.4 GHz and 5 GHz networks have different names (SSIDs)

Find your iPhone's MAC address in the list of connected devices.

View the "Range" or "Band" column

If there is no data, disable Smart Connect and reconnect-->

Method 2: By network name (if SSIDs are different)

Many routers create a default two separate networks for different ranges, adding suffixes to the name like _2G, _5G or -5. For example:

• MyWiFi_2.4G → frequency 2.4 GHz.
• MyWiFi_5G → frequency 5 GHz.

How to check:

1. Open Settings → Wi-Fi.
2. Look at the name of the current network (next to the check mark ✔️).
3. If the name indicates a range, that is your frequency.

If there are no suffixes, but you suspect that the networks are separate, try manually connecting to an alternative SSID (for example, if you see two networks with the same beginning).

If your router is not listed in the table, check its documentation or the sticker on the case - sometimes suffixes are indicated there.

Method 3: Via the Home app (for HomeKit users)

If you use Apple HomeKit and your router supports this system (for example, AirPort Extreme, Eero or compatible models TP-Link/ASUS), you can find out the frequency through the application House:

1. Open the app House on iPhone.
2. Tap on the icon ⚙️ Home settings (in the upper right corner).
3. Select Routers and Wi-Fi networks.
4. Click on your router in the list.
5. In the section Connected devices find yours iPhone — the range will be indicated next to it (2.4 GHz or 5 GHz).

⚠️ Note: This method only works if the router is added to HomeKit and supports network monitoring. On older router models or without configuration HomeKit data may be missing.

Method 4: Connection speed analysis (indirect method)

This method does not give precise answer, but it allows you to make an educated guess. Based on the fact that 5 GHz usually provides higher speeds with a good signal.

Instructions:

1. Connect to a Wi-Fi network.
2. Open Settings → Wi-Fi and tap on the network name (next to ✔️).
3. Remember the value in the line IP address (For example, 192.168.1.100).
4. Run a speed test:
   • IN Safari open speedtest.net or fast.com.
   • Run the test and record the download speed (Download).

• 2.4 GHz: to 200–300 Mbps (really 50–150 Mbps).
• 5 GHz: to 500–800 Mbps (really 200–500 Mbps).

Example of interpretation:

• 📉 Speed 70 Mbps at the signal 3/3 → most likely 2.4 GHz.
• 📈 Speed 400 Mbps at the signal 2/3 → most likely 5 GHz.

Limitations of the method:

• 📡 Other factors also affect speed: network congestion, provider tariff, interference.
• 🔄 If the router uses Smart Connect, iPhone can automatically switch between ranges.

Method 5: Using Shortcuts (for advanced users)

If you are willing to spend 5-10 minutes setting it up, you can create automated script in the app Shortcuts (set by default to iOS). It will analyze the network data and give you a probable range.

Instructions:

1. Open the app Shortcuts.
2. Tap + (create a new shortcut).
3. Click Add action and find the team Get network information.
4. Add an action If and set up the condition:

   If "SSID" contains "_5G" or "5GHz"
   Then: Show the notification "You are connected to 5 GHz"
   Otherwise: Show the notification "You are connected to 2.4 GHz"

5. Save the shortcut and run it.

An example of a finished shortcut can be downloaded Here (will open in Shortcuts).

⚠️ Note: This method only works if the network name contains an explicit range (as in Method 2). For networks with Smart Connect or the same SSID it is useless.

Common mistakes and how to avoid them

When determining the Wi-Fi frequency on iPhone Users often encounter typical problems. Here's how to solve them:

• 🔍 I can't see the range in the router.:

  Make sure that in your router settings Smart Connect is disabled (it connects networks). Also check that your iPhone connected to the correct network - sometimes devices automatically switch to a less crowded band.

• 📵 "iPhone won't connect to 5GHz":

  Check if your model supports it iPhone this range (all models with iPhone 5 and newer ones support it). If the router uses 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6), and on iPhone old firmware - update iOS.

• 🔄 "The frequency is constantly changing.":

  It's normal if it's on Smart Connect or function Band Steering (automatic switching). To fix the range, disable these options in your router or create separate networks for 2.4 and 5 GHz.

If none of the methods worked, try alternative approach:

1. Turn it off iPhone from Wi-Fi.
2. In the router settings temporarily disable the 2.4 GHz network (leaving only 5 GHz).
3. Reconnect - if the connection is established, then you were previously on 2.4 GHz.
