How to Check if Your Wi-Fi Is Running on 2.4GHz—Not 5GHz

Are you connected to Wi-Fi, but the speed is poor, and some devices (like smart light bulbs or old printers) refuse to see the network at all? The problem may be router broadcast frequencyModern routers support two ranges: 2.4 GHz And 5 GHz, and it is not always clear which one your device is connected to.

Range 2.4 GHz has a longer range and penetrates walls better, but is susceptible to interference from other networks and household appliances (microwaves, baby monitors). 5 GHz faster and more stable, but the signal penetrates less well through obstacles. If you need to connect a device that only works on 2.4 GHz (For example, Xiaomi Mi Home or TP-Link TL-WN725N), it is important to make sure that the router broadcasts in this range, and the gadget is connected to it.

In this article you will find 5 Ways to Check Wi-Fi Frequency on various devices—from smartphones to smart TVs. You'll also learn how to force a switch to the desired band if automatic selection (for example, Smart Connect on ASUS or Band Steering on TP-Link) is not working properly.

⚠️ Attention: Some router manufacturers (eg. Keenetic or MikroTik) hide the 5 GHz SSID by default, combining the networks into one. In this case, checking the frequency on the client device is the only reliable method.

1. How to check Wi-Fi frequency on Windows 10/11

On computers with Windows You can determine the range of a connected network without third-party programs, using the system's built-in tools. This method works on both laptops and PCs with external Wi-Fi adapters (e.g., TP-Link Archer T2U).

Open Settings → Network and Internet → Wi-FiFind your network name (SSID) and click on it. In the window that opens, scroll down to the section "Properties"There will be a line here Radio communication type (or Radio type (in the English version). If it is indicated there 802.11n or 802.11g - This 2.4 GHz. If 802.11ac or 802.11ax - more likely, 5 GHz (but not always, see table below).

  • 📡 802.11b/g/n - only 2.4 GHz (maximum speed up to 600 Mbps).
  • 🚀 802.11a/n/ac/ax - maybe so 2.4 GHz, And 5 GHz (further verification required).
  • ⚠️ 802.11n — the only standard that works in both ranges.

For precise determination use command line:

  1. Click Win + R, enter cmd and confirm.
  2. Enter the command: 
    netsh wlan show interfaces
  3. Find the line Radio module type (Radio type). If there 802.11n, look at Number of channels (Channel): 1–14 - This 2.4 GHz, 36–165 — 5 GHz.

2. Checking the frequency on an Android smartphone or tablet

On Android There is no universal way to see the Wi-Fi frequency in the settings - it all depends on the OS version and the manufacturer's shell (MIUI, One UI, ColorOS etc.). However, there are workarounds.

Method 1: via the app WiFi Analyzer (recommended)

  1. Install the free app WiFi Analyzer (from farproc) from Google Play.
  2. Open it and go to the tab AP List (AP List).
  3. Find your network in the list. In the column Frequency (Freq.) the value will be indicated:
    • 📶 2412–2484 MHz → 2.4 GHz (channels 1-14).
    • 📶 5180–5825 MHz → 5 GHz (channels 36–165).

Method 2: Through the engineering menu (for advanced users)

On some smartphones (eg. Xiaomi, Samsung, Realme) you can use the hidden engineering menu:

  1. Open the app Telephone and dial ##4636##.
  2. Go to Wi-Fi information (or Wi-Fi Information).
  3. Find the line Frequency — there will be a value in MHz (see the explanation above).
📊 What device do you use to check your Wi-Fi most often?
Smartphone
Laptop
Tablet
Smart TV
Other

⚠️ Attention: On smartphones with chips Mediatek (many models Redmi, POCO) the engineering menu may not show the frequency. In this case, use WiFi Analyzer or check your router settings.

3. How to find the Wi-Fi frequency on an iPhone or iPad

Apple simplified the interface as much as possible iOS/iPadOS, removing technical details like Wi-Fi frequency from the default settings. However, there are two working methods.

Method 1: via the app AirPort Utility (official decision)

  1. Install the utility AirPort Utility from App Store (for free).
  2. Open Settings → Wi-Fi and tap on the icon ℹ near your network.
  3. Scroll down and select AirPort Utility (AirPort Utility).
  4. In the window that opens, go to the tab Wi-Fi and look at the field Radio Mode:
    • 📻 802.11b/g/n → 2.4 GHz.
    • 📻 802.11a/n/ac/ax → 5 GHz (or 2.4 GHz, if channel 1–14 is specified).

Method 2: Via a router (if the iPhone doesn't show it)

If the utility does not give a clear answer, check the router settings (instructions in Section 5). On iPhone can also be used Shortcuts (Shortcuts) to automatically detect the frequency, but this requires creating a custom script.

Why doesn't my iPhone show the frequency in settings?

Apple deliberately hides technical details from users to simplify the interface. This is part of the company's "it just works" philosophy. However, this approach creates difficulties for network diagnostics, especially when connecting a device that only operates on 2.4 GHz.

4. Test on MacBook or iMac

On computers Mac With macOS You can find out your Wi-Fi frequency using the built-in utility Wireless Diagnostics or a terminal. The first method is simpler and doesn't require commands.

Method 1: Via Wireless Diagnostics

  1. Hold down the key Option (⌥) and click on the Wi-Fi icon in the menu bar.
  2. Select Open Wi-Fi diagnostics (Open Wireless Diagnostics).
  3. In the window that opens, ignore the diagnostic wizard and go to the menu Window → Utilities (or Window → Utilities).
  4. Select a tab Wi-Fi Scan and press Scan Now.
  5. In the results, find your network and look at the column Channel:
    • 📊 1–14 → 2.4 GHz.
    • 📊 36–165 → 5 GHz.

Method 2: via Terminal

For experienced users, the following command is suitable:

/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I

Find the line in the results channelIf the value is from 1 to 14 - This 2.4 GHz.

5. How to check the Wi-Fi frequency directly on the router

The most reliable way is to access your router's web interface and view your wireless network settings. This is especially useful if your device doesn't display the frequency (for example, Smart TV or smart speaker).

Step 1: Login to your router's control panel

  1. Open your browser and enter the following into the address bar:
    • 🌐 192.168.0.1 (For TP-Link, D-Link, Tenda).
    • 🌐 192.168.1.1 (For ASUS, Zyxel, Mercusys).
    • 🌐 my.keenetic.net (For Keenetic).
  • Enter your login and password (usually admin/admin, if you haven't changed it).

    • Step 2: Find Wi-Fi settings

    The interface varies depending on the model. Look for sections like:

    • 📡 Wireless → Wireless Settings (TP-Link, Mercusys).
    • 📡 Wireless network → Basic settings (ASUS, Keenetic).
    • 📡 Network → Wi-Fi (Zyxel, Tenda).

    Step 3: Determine the range

    In the settings, look for the following parameters:

    Parameter Value for 2.4 GHz Value for 5 GHz
    Band / Range 2.4 GHz or B/G/N 5 GHz or A/N/AC/AX
    Channel / Channel 1–14 36–165
    Wireless Mode 802.11b/g/n or Legacy 802.11a/n/ac/ax or 5G
    SSID (network name) Often contains _2G, 2.4 or -G Often contains _5G, 5 or -A

    ⚠️ Attention: If it is enabled in the router Smart Connect (combining 2.4 and 5 GHz networks under one SSID), the current range can only be determined on the client device (see Section 1 or Section 2).

    Check if the networks are merged in the Smart Connect settings | Update the router firmware | Try connecting to the network from another device | Reset the router to factory settings (last resort) -->

    6. Testing on Smart TVs, set-top boxes, and other devices

    On televisions (Samsung, LG, Sony, Xiaomi) and prefixes (Apple TV, NVIDIA Shield, Android TV-box) The default settings rarely show the Wi-Fi frequency. Here's what you can do:

    For Android TVs (Sony, Xiaomi, Philips):

    1. Install the application WiFi Analyzer from Google Play (if there is support).
    2. Or connect to TV via ADB and run the command: 
      adb shell dumpsys wifi

      Look in the results frequency (value in MHz).

    For Samsung Tizen or LG webOS:

    • 📺 On Samsung go to Settings → General → Network → Network StatusSometimes the frequency is indicated in the connection details.
    • 📺 On LG open Settings → Network → Wi-Fi DetailsIf there is no data, use router (cm. Section 5).

    For set-top boxes (Apple TV, Fire Stick, Roku):

    • 🎮 On Apple TV The frequency is not displayed. Check through a router or another device.
    • 🔥 On Fire TV Stick install WiFi Analyzer from Amazon Appstore.
    • 📦 On Roku go to Settings → Network → AboutThe frequency may be indicated next to Network name.

    7. How to force a connection to 2.4 GHz (if automatic selection doesn't work)

    If your router supports both ranges, but the device stubbornly connects to 5 GHz (for example, because of Band Steering), there are several ways to force switching:

    Method 1: Disable 5 GHz in your router settings

    1. Go to the router control panel (see Section 5).
    2. Find the settings 5 GHz and temporarily turn it off this network (parameter Enable 5GHz or similar).
    3. Save the settings. The device will now automatically connect to 2.4 GHz.
    4. After connecting, you can turn it on again 5 GHz.

    Method 2: Create a separate SSID for 2.4 GHz

    Many routers allow you to divide networks by ranges:

    1. In the Wi-Fi settings, find the option Separate Bands or Split the networks.
    2. Set different names (SSID) for 2.4 GHz And 5 GHz, For example:
      • 🔄 MyWiFi_2G - For 2.4 GHz.
      • 🔄 MyWiFi_5G - For 5 GHz.
  • Connect your device to the network with _2G in the name.

    • Method 3: Change the settings on the client device

    On Android (with root rights) or Windows You can manually specify the preferred range:

    • 🖥️ On Windows open device Manager, find the Wi-Fi adapter, go to Properties → Advanced and install Preferred Band in meaning 2.4 GHz.
    • 🤖 On Android with root use the app WiFi Band to force range selection.

    ⚠️ Attention: If after disconnection 5 GHz some devices (eg MacBook or iPhone) stopped connecting to Wi-Fi, check if they support it 5 GHz only (rare, but it happens on older models).

    8. Common problems and solutions

    When checking Wi-Fi frequencies, users encounter typical difficulties. Here are the most common ones and solutions:

    Problem Possible cause Solution
    The device does not see the 2.4 GHz network, although it is there The 2.4 GHz band is disabled in the router or the MAC filter is enabled. Check your router settings (enable 2.4 GHz, disable filtering)
    The smartphone shows the frequency, but the laptop does not. The laptop has an outdated Wi-Fi adapter driver. Update driver via device Manager or the manufacturer's website
    The router shows that the 2.4 GHz network is enabled, but devices are not connecting. Incorrect channel selected (overload or interference) Manually set channel 1, 6 or 11 in the router settings
    After splitting the SSID, devices do not connect to 2.4 GHz Incorrect safety standard (eg. WPA3 not supported) Install WPA2-PSK for 2.4 GHz network

    ⚠️ Attention: If you use mesh system (For example, TP-Link Deco, Google Nest Wi-Fi), bands can switch automatically depending on the load. In this case, locking the device to a specific frequency is difficult—please refer to the documentation for your model.

    FAQ: Answers to Frequently Asked Questions

    Is it possible to use 2.4GHz and 5GHz on one router at the same time?

    Yes, almost all modern routers (for example, ASUS RT-AX88U, TP-Link Archer C6, Keenetic Extra) support simultaneous work in both ranges. You can:

    • Combine networks under one SSID (mode Smart Connect).
    • Separate networks by assigning different names (eg. MyWiFi_2G And MyWiFi_5G).

    Please note: Some budget models (eg. Tenda N301) work only in one range.

    Why can't my device see the 5 GHz network?

    Possible reasons:

    • 📵 The device does not support 5 GHz (for example, older smartphones or printers).
    • 📵 The 5 GHz band is disabled in the router.
    • 📵 The 5 GHz channel is configured to DFS (dynamic frequency selection), which some devices do not support.
    • 📵 The country/region in the router settings is set incorrectly (for example, Russia instead of Europe).

    Solution: Check your router settings and device specifications.

    Which 2.4 GHz channel should I choose for minimum interference?

    In the range 2.4 GHz channels overlap, so to minimize interference, use only non-intersecting channels:

    • 📶 Channel 1 (2412 MHz).
    • 📶 Channel 6 (2437 MHz).
    • 📶 Channel 11 (2462 MHz).

    Use the app WiFi Analyzerto see channel load in your region.

    Is it possible to increase the speed on 2.4 GHz?

    Yes, but with limitations. The maximum theoretical speed in the standard 802.11n (2.4 GHz) - 600 Mbps, but in practice it rarely exceeds 100–150 Mbps due to interference. To improve speed:

    • 🔧 Set the channel width 40 MHz (but this may increase interference).
    • 🔧 Switch to standard 802.11n (turn off 802.11b/g for compatibility).
    • 🔧 Update your router firmware.
    • 🔧 Use MIMO (multi-channel mode) if your router supports it (for example, ASUS RT-AX58U).

    For a real speed boost, consider upgrading to 5 GHz or Wi-Fi 6 (802.11ax).

    Why do smart devices (lamps, sockets) only work on 2.4 GHz?

    Most devices smart home (For example, Xiaomi Mi Home, Tuya Smart, Sonoff) use chips ESP8266 or ESP32, which:

    • 💡 Cheaper to produce.
    • 💡 Consume less energy (important for battery-powered devices).
    • 💡 Have better signal penetration (important for sensors located far from the router).

    The exception is some flagship models (for example, Philips Hue or Nest Thermostat), which support both ranges.
