How to check Wi-Fi frequency: 2.4 GHz or 5 GHz – all methods

Have you noticed that your internet speed on some devices suddenly drops, even though your router shows a stable connection? Or is your new smartphone stubbornly refusing to detect the 5 GHz network, even though it's definitely enabled? The problem could be... incorrectly selected Wi-Fi frequency. Ranges 2.4 GHz And 5 GHz They differ not only in speed, but also in coverage area, resistance to interference, and compatibility with devices.

In this article you will find 7 proven methodsHow to determine the current Wi-Fi frequency on any device—from a laptop to a smart TV. We'll explore why it's important to know which band you're connected to and what to do if your device doesn't see the network you need. You'll also learn how Force switching between frequencies without resetting the router settings — This trick works even on budget router models.

Why is it important to know your Wi-Fi frequency?

Ranges 2.4 GHz And 5 GHz They solve different problems, and choosing the wrong one can cost you half your internet speed. Here are the key differences:

  • 📶 2.4 GHz: Wide coverage area (passes through walls), but susceptible to interference from microwaves, Bluetooth devices, and neighbors. Maximum speed - up to 600 Mbps (theoretically).
  • 🚀 5 GHz: high speed (up to 1.3 Gbps in standard Wi-Fi 5), but has poorer obstruction penetration. Ideal for online gaming and 4K streaming.
  • ⚠️ Dual-band routers: often two networks with the same name are created (SSID), and the device itself selects the frequency - not always optimal.

Example from practice: if your Smart TV connected to 2.4 GHz, and you watch the movie in 4K HDR, the image may "slow down" due to lack of bandwidth. Switching to 5 GHz will solve the problem - but first you need to understand what network you are currently connected to.

⚠️ Note: Some older devices (such as printers) HP LaserJet before 2016 or smart light bulbs Xiaomi Yeelight first series) work only on 2.4 GHzIf you've hidden this network in your router settings, they'll lose connection.

Method 1: Checking the frequency on Windows 10/11

On computers with Windows You can find out your Wi-Fi frequency without third-party programs, using built-in tools. Here are the step-by-step instructions:

  1. Click Win + X and select "Device Manager".
  2. Expand the tab Network Adapters and find the name of your Wi-Fi module (for example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA9377).
  3. Right-click on the adapter → "Properties" → tab "Additionally".
  4. On the list "Property" find the item Wireless Mode, Band or Preferred BandThe current frequency will be indicated in the value (for example, 802.11a - This 5 GHz, 802.11b/g2.4 GHz).

If the point Band No, use an alternative method:

  1. Open Command line (Win + R → enter cmd).
  2. Enter the command:
    netsh wlan show interfaces
  3. Find the line Radio Type (Radio Type). Values:
    • 802.11n — can work on both frequencies (you need to check in your router settings).
    • 802.11ac or 802.11ax - only 5 GHz.
    • 802.11b/g - only 2.4 GHz.

Check your Wi-Fi adapter drivers (update them through Device Manager)

Make sure your router is broadcasting both 2.4 and 5 GHz networks.

Restart your router and PC

Try connecting to another network to test-->

Method 2: Determining the frequency on an Android smartphone

On Android There's no universal way to check Wi-Fi frequency—it all depends on the OS version and manufacturer. But there are workarounds:

  • 📱 Method for pure Android (Pixel, Nokia, Motorola):
    1. Open "Settings"«Wi-Fi».
    2. Tap on the name of your network.
    3. Look at the line "Frequency" or "Speed". If specified 802.11ac or 5 GHz - This 5 GHz; If 802.11n (2.4 GHz) - respectively, 2.4 GHz.
  • 🤖 For Samsung, Xiaomi, Huawei:

    Manufacturers often hide this information. Use the app WiFi Analyzer (free in Google Play):

    1. Install and open the application.
    2. Go to the tab Access Point List.
    3. Find your network - the frequency will be indicated in the column «Band».
  • If the app shows that your smartphone is connected to 2.4 GHz, but you want to switch to 5 GHz, do the following:

    1. Forget the network in Wi-Fi settings.
    2. In the router settings split the SSID for 2.4 and 5 GHz (for example, MyWiFi_2G And MyWiFi_5G).
    3. Connect to the network with _5G in the title.

    Method 3: Check on iPhone or iPad

    Apple simplified the interface as much as possible iOS, but also hid many technical details. To find out the Wi-Fi frequency on iPhone or iPad, you will have to use a workaround:

    1. Install the free app AirPort Utility from App Store (it's from Apple, safe).
    2. Open the app and tap on «Wi-Fi Scan» in the upper right corner.
    3. Click «Scan» and wait for the scanning to complete.
    4. Find your network in the list - the frequency will be indicated in the column «BAND» (2.4 GHz or 5 GHz).

    If the app doesn't show your network, try an alternative method:

    1. Connect to Wi-Fi.
    2. Open "Settings"«Wi-Fi» and tap on the symbol «i» next to the network name.
    3. Look at the line Router (Router). If the IP address starts with 192.168. or 10.0., most likely it is 2.4 GHz (but not always!).
    ⚠️ Attention: Starting from iOS 17, Apple may block access to Wi-Fi frequency information for third-party applications. If AirPort Utility If it doesn't work, check the frequency through the router settings (method 5).

    Method 4: How to find the frequency on macOS

    On MacBook or iMac Checking the Wi-Fi frequency is easier than iPhoneHere are two working methods:

    • 🖥️ Via "System Information":
      1. Hold Option (Alt) and click on the Wi-Fi icon in the menu bar.
      2. Select Open Wireless Network Diagnostics.
      3. In the window that opens, click "Window""Scanner".
      4. Find your network - the frequency will be in the column «BAND».
  • 🔍 Via the Terminal:
    1. Open "Terminal" (through Spotlight or folder Utilities).
    2. Enter the command:
      /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I
    3. Find the line «channel»If the value is from 1 to 14 - This 2.4 GHz; if from 36 to 1655 GHz.
    4. If your Mac doesn't see the network 5 GHz, check:

      • Does your model support 5 GHz (For example, MacBook Air 2015 and older - yes, but MacBook 2009 - No).
      • Is the network turned on? 5 GHz in the router settings (sometimes it is disabled by default).

      Method 5: Checking through the router settings

      The most reliable way is to access your router's web interface. There, you'll see not only the current frequency but also all connected devices and their ranges. Instructions:

      1. Find out your router's IP address:
        • On Windows: Win + Rcmd → enter ipconfig → find Main Gateway.
        • On Mac/Linux: in the terminal, enter netstat -nr | grep default.
        • On Android/iOS: look in the Wi-Fi settings (next to the network name).
    5. Enter the IP address into the address bar of your browser (usually 192.168.0.1, 192.168.1.1 or 192.168.8.1).
    6. Enter your login and password (by default it is often admin/admin or indicated on the router sticker).
    7. Go to the section Wireless Network (Wireless). Look for tabs like:
      • 2.4GHz Wireless And 5GHz Wireless (on dual-band routers).
      • Basic SettingsWireless Mode.
  • View the list of connected devices («DHCP Clients» or «Connected Devices») - the frequency for each gadget may be indicated there.
  • Example for popular routers:

    Router brand Path to frequency settings What does the frequency look like in the interface?
    TP-Link Advanced → Wireless → Wireless Settings Points 2.4GHz And 5GHz as separate tabs
    ASUS Wireless → General Field Band with a choice 2.4GHz/5GHz
    Keenetic Wi-Fi network → Additional settings List Radio bands with check marks
    Xiaomi Settings → Wi-Fi Switch 2.4G/5G at the top of the screen
    ⚠️ Attention: On some routers (for example, ZTE or Huawei (from providers) access to frequency settings may be blocked. In this case, contact technical support or reset the router to factory settings (button Reset on the back panel).
    What to do if you can't access your router?

    If the standard password (admin/admin) does not work, try:

    1. Look at the login/password on the sticker on the bottom of the router.

    2. Enter user/user or leave the password field blank.

    3. Reset the router settings using the button Reset (hold for 10 seconds).

    If nothing helps, your router may have been blocked by your provider – call support.

    Method 6: Determining the frequency on Smart TV and other devices

    Smart TVs, game consoles, and even some printers connect to Wi-Fi, but they don't always display the frequency. Here's how to find it:

    • 📺 Smart TV (Samsung, LG, Sony):
      1. Open "Settings""Net"Network Status.
      2. On Samsung frequency can be specified in the section Details (Details).
      3. On LG With webOS go to "Additional settings" (Advanced Settings).

    If there is no information, connect to the router via cable and check the frequency through its web interface (method 5).

  • 🎮 Game consoles (PS5, Xbox Series X, Nintendo Switch):
    1. On PlayStation 5: "Settings""Net"Connection StatusThe frequency is indicated in the line "Frequency range".
    2. On Xbox: "Settings"GeneralNetwork Settings"Additional Options".
    3. On Nintendo Switch The frequency is not displayed - use the method with the router.
    4. 🖨️ Printers and MFPs:

      Most printers (eg. Canon PIXMA or Epson EcoTank) connect only to 2.4 GHzIf the printer does not see the network, check:

      • Is the network turned on? 2.4 GHz on the router.
      • Isn't it hidden? SSID for this range.
      • Is encryption used? WPA3 (some older printers do not support it).
  • If your device does not display a frequency but you suspect it is connected to 2.4 GHz, try it force switch to 5 GHz:

    1. In the router settings disable the 2.4 GHz network for 10 minutes.
    2. Restart your device (TV, set-top box).
    3. If it connects to the internet, it's now on 5 GHz.
    4. Reset your router settings back.

    Method 7: Using third-party programs to analyze Wi-Fi

    If standard methods fail, specialized utilities can help. They not only show the frequency but also analyze signal quality, channel congestion, and interference.

    • 💻 For Windows:
      • WiFi Analyzer (from Microsoft Store) - shows the frequency, signal strength and occupied channels.
      • NetSpot - Builds a coverage heat map and indicates the range for each network.
      • inSSIDer - a professional tool with detailed information about standards (802.11ac/ax) and channel width.
    • 📱 For Android:
      • WiFi Analyzer (from farproc) - shows the frequency in real time.
      • Network Analyzer — analyzes the speed and stability of the connection.
    • 🍎 For macOS:
      • WiFi Explorer — a paid, but the most accurate application for network analysis.
      • NetSpot — free version with basic functions.

    Example of working with WiFi Analyzer on Windows:

    1. Download and install the program.
    2. Start scanning.
    3. Find your network in the list. In the column «Band» the frequency will be indicated.
    4. Pay attention to the column «Channel Width»:
      • 20 MHz - standard width, suitable for 2.4 GHz.
      • 40/80/160 MHz — extended width, typical for 5 GHz (gives more speed, but can create interference).
    ⚠️ Attention: Some programs (for example, inSSIDer) require administrator rights and may conflict with antivirus software. Add them to the exceptions list before installation.

    Common problems and solutions

    When checking Wi-Fi frequency, users encounter common errors. Here's how to avoid them:

    • 🔄 The device does not see the 5 GHz network:

      Reasons and solutions:

      • The device does not support 5 GHz (check model specifications).
      • The range is disabled in the router 5 GHz (enable in settings).
      • The distance to the router is too great - 5 GHz does not pass through walls well.
      • The router is in the enabled mode 802.11n only — switch to 802.11a/n/ac or 802.11ax.
    • 📉 The speed on 5 GHz is slower than on 2.4 GHz.:

      It's a paradox, but it's possible. Reasons:

      • Weak signal 5 GHz (move the router closer).
      • Interference from other networks (use an analyzer program to change the channel).
      • The device is connected using the old standard 802.11a (maximum 54 Mbps).
    • 🔒 I can't connect to a hidden 5GHz network.:

      Hidden Networks (Hidden SSID) often cause problems. Solution:

      1. In the router settings make the network temporarily visible.
      2. Connect to it.
      3. Reset the stealth settings back.

    If none of the methods helped, try reset network settings on the device:

    • On Windows: ParametersNetwork and InternetNetwork Reset.
    • On Android: "Settings""System"ResetReset Wi-Fi settings.
    • On iOS: "Settings""Basic"ResetReset network settings.

    FAQ: Answers to frequently asked questions

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

    No, the device only connects to one band at a time. However, some routers support Band Steering technology (for example, in the standard Wi-Fi 6), which automatically switches devices between frequencies for optimal speed. However, this doesn't always work correctly—it's better to separate the networks manually.

    Which 5GHz channel should I choose for maximum speed?

    In the range 5 GHz recommended channels 36-48 (lower range) or 149-165 (higher range, less crowded). Avoid channels 50-144 - they may require support DFS (dynamic frequency selection) and automatically switch when radars are detected (for example, at airports).

    Why does my laptop connect to 2.4GHz even though 5GHz is available?

    This is a typical driver or power saving settings issue. Check:

    1. IN Device Manager Update your Wi-Fi adapter driver.
    2. IN "Control Panel"Power Supply"Scheme Settings""Additional Options" find the item Wireless Adapter Settings and install Maximum Performance.
    3. Disable it in your router settings. Band Steering (if any) and separate the networks into different SSID.
    How do I check if my device supports 5GHz?

    There are several ways:

    • Check the model specifications on the manufacturer's website (look for standards support) 802.11a, 802.11ac or 802.11ax).
    • On Windows check in Device ManagerNetwork Adapters"Properties" → tab "Additionally" (look for Wireless Mode).
    • On Android install WiFi Analyzer and see if the device sees the network 5 GHz (even if it doesn't connect).

    If your device was released before 2012, it most likely only supports 2.4 GHz.

    Is it possible to increase the range of the 5GHz signal?

    Yes, but with restrictions:

    • Use powerful
