How do you know if your Wi-Fi is 2.4GHz or 5GHz?

Have you noticed that your Wi-Fi speed has suddenly dropped, or YouTube videos are constantly freezing? Or maybe your new smart device refuses to connect to the network, even though you've entered the correct password? The cause is often... incorrectly selected Wi-Fi frequency. Routers of modern standards (Wi-Fi 5/6/6E) broadcast simultaneously on two ranges - 2.4 GHz And 5 GHz, but not all devices support both. Moreover, even if a gadget "sees" both networks, automatic connection doesn't always select the optimal option.

In this article, you'll learn how to accurately determine what frequency your Wi-Fi is operating on—right now, without complicated settings. We'll cover the methods for Windows, macOS, Android, iOSWe'll also show you how to check the frequency directly in your router settings. Plus, we'll identify hidden pitfallsWhy some devices get stuck on 2.4 GHz even when 5 GHz is available, and how to fix it. Let's start with the basics—without them, it's impossible to understand why frequency selection is so important for network stability.

Why is it important to know your Wi-Fi frequency: 2.4 GHz vs. 5 GHz?

Ranges 2.4 GHz And 5 GHz — these are not just numbers. They determine speed, range And stability your connection. Here are the key differences:

  • 📶 2.4 GHz: Better through walls, but susceptible to interference from microwaves, Bluetooth devices, and neighbors. Maximum speed - up to 600 Mbps (theoretically).
  • 🚀 5 GHz: higher speed (up to 1.3 Gbps V Wi-Fi 5 And 9.6 Gbps V Wi-Fi 6E), but the signal penetrates less well through obstacles. Suitable for streaming video and gaming.

The problem is that many devices (especially smart light bulbs, cameras or old smartphones) work only on 2.4 GHzIf the router is set to automatically select a frequency, they may simply not see the network. On the other hand, a laptop or iPhone The latest model will “slow down” on the overloaded 2.4 GHz, although 5 GHz is free nearby.

⚠️ Please note: Some providers (eg. Rostelecom or Beeline) 5 GHz is disabled by default in rented routers. If you can't find this band, check your settings or contact support.

Now let's move on to practice. We'll start with the simplest method—testing on a connected device.

📊 Which Wi-Fi band do you use most often?
2.4 GHz only
5 GHz only

I don't know what mine is

Method 1: How to find the Wi-Fi frequency on Windows 10/11

If you are connected to the network from a laptop or PC running WindowsYou can determine the frequency in 30 seconds—without installing any additional software. Here are the step-by-step instructions:

  1. Press the keyboard shortcut Win + X and select "Device Manager".
  2. Expand the section Network Adapters.
  3. Find yours Wi-Fi adapter (usually contains words Wireless, Wi-Fi or a brand name, for example Intel AX200).
  4. Right click on it and select "Properties".
  5. Go to the tab "Additionally".
  6. On the list "Property" find the item Band or Preferred Band. It will be indicated here. 2.4 GHz or 5 GHz.

If the point Band No, try another way:

  • 🖥️ Open “Settings” → “Network and Internet” → “Wi-Fi”.
  • 📊 Click on the current network and select "Properties".
  • 🔍 Scroll down to the section "Properties" — the frequency may be indicated there (Network bandwidth).

On some adapters (eg. Qualcomm Atheros) the frequency is displayed in "State" adapter. To get there:

Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings → Right-click on Wi-Fi → Status
⚠️ Attention: If the adapter properties indicate Auto or 802.11a/b/g/n/ac/ax, this means that the device selects the frequency itself. In this case, it is better to check the frequency through command line (the method is described below).

Open Device Manager|Find your network adapter|Check the Advanced tab|Look for Band or Preferred Band-->

Method 2: Command Line (for advanced users)

This method is suitable if the GUI doesn't display the frequency or you prefer to work with commands. It is universal for all versions. Windows and gives an accurate result.

Open command line as administrator (click Win + S, enter cmd, then Ctrl + Shift + Enter) and run the command:

netsh wlan show interfaces

Find the line in the results Radio Type (Radio type). There will be one of the values:

  • 📻 802.11n - can work on both frequencies (needs clarification).
  • 📶 802.11g or 802.11b - only 2.4 GHz.
  • 🚀 802.11a or 802.11ac - only 5 GHz.
  • 🔄 802.11ax (Wi-Fi 6) - supports both ranges.

If the radio type does not give a clear answer, run the second command:

netsh wlan show networks mode=bssid

The results will contain a column «Channel»Channels 1 through 14 are related to 2.4 GHz, and channels from 36 and above - to 5 GHz.

Method 3: Checking the frequency on Android and iOS

On mobile devices, determining the Wi-Fi frequency is more difficult, as manufacturers often hide this information. However, there are workarounds.

For Android

Standard settings Android They don't show the frequency, but you can find it using third-party apps. The most reliable ones are:

  • 📱 WiFi Analyzer (from farproc) — shows the channels and frequencies of neighboring networks. Your network will be highlighted in green.
  • 🔍 Network Analyzer — in the section «Wi-Fi Networks» displays the range (2.4G or 5G).
  • 📊 WiFi SweetSpots — visualizes channel load.

If you don't want to install apps, try this trick (may not work on all phones):

  1. Open Settings → Wi-Fi.
  2. Tap and hold the current network name.
  3. In some firmware (for example, Xiaomi MIUI or Samsung One UI) a window will appear with detailed information, including the frequency.

For iPhone (iOS)

Apple It limits access to technical data to the maximum extent possible, so it's impossible to find out the frequency without jailbreaking or additional devices. But there is a workaround:

  • 📱 Install the application AirPort Utility (official from Apple).
  • 🔧 Turn on Wi-Fi Scanner Mode in the application settings (in the upper right corner).
  • 📊 Click «Wi-Fi Scan» and find your network in the list. In the column «Band» the frequency will be indicated.

If you have MacBook or iMac, it's easier to check the frequency through macOS (the method is described below).

⚠️ Attention: On iPhone with iOS version below 14.0 application AirPort Utility Doesn't show the frequency. Update the system or use a different device.

Method 4: How to check Wi-Fi frequency on macOS

On computers Apple It's easier to determine the frequency than on iPhoneHere are two working methods:

Method 1: Using Wireless Network Diagnostics

  1. Hold down the key Option (⌥) and click on the icon Wi-Fi in the menu bar.
  2. Select Open Wireless Network Diagnostics.
  3. In the window that opens, click Continue and wait for the data to be collected.
  4. In the section Summary find the line «Channel»Channels 1-14 are 2.4 GHz, the rest are - 5 GHz.

Method 2: Via Wireless Network Monitor

This method provides more technical details:

  1. Open Programs → Utilities → Wireless Network Monitor.
  2. In the menu, select «Window» → «Scan».
  3. In the table, find your network and look at the column «Channel».

If you have MacBook Pro or MacBook Air with a chip M1/M2, the summary will also indicate the Wi-Fi standard (for example, 802.11ax), which indirectly confirms the support 5 GHz.

What to do if macOS doesn't show the frequency?

If none of the methods worked, try connecting to the network via Terminal with the team:

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

The results will contain a column CHANNEL, by which the range can be determined.

Method 5: Check the frequency in the router settings

The most reliable way is to check your router's control panel. There, you'll see not only the current frequency but also other important parameters: channel width, Wi-Fi standard, and even a list of connected devices with their bands.

The instructions are universal for most models (TP-Link, Asus, Keenetic, MikroTik, Zyxel), but the paths may differ slightly:

  1. Open your browser and enter your router's IP address. This is usually:
    • 🌐 192.168.0.1 (For TP-Link, D-Link)
    • 🌐 192.168.1.1 (For Asus, Zyxel)
    • 🌐 192.168.8.1 (For Huawei)
    • 🌐 my.keenetic.net (For Keenetic)
  • Enter your login and password (by default it is often admin/admin or indicated on the router sticker).
  • Go to the section Wireless Network (Wireless).
  • Find the tabs or blocks with the names:
    • 📶 2.4GHz And 5GHz (if the router is dual-band)
    • 🔄 Band or Wireless Mode
    • Check which band is enabled. If both are active, check which one your devices are connected to (there's usually a list of clients).

    Example of a router interface TP-Link Archer C6:

    Parameter 2.4 GHz 5 GHz
    Standard (Mode) 802.11n (up to 300 Mbps) 802.11ac (up to 867 Mbps)
    Channel 6 (auto) 36 (auto)
    Channel width 20/40 MHz 80 MHz
    Network name (SSID) MyWiFi_2G MyWiFi_5G
    ⚠️ Attention: If the router settings indicate «Smart Connect» or «Band Steering»This means the router automatically switches devices between 2.4 GHz and 5 GHz. In this case, the current frequency can only be accurately determined on the device itself (see methods above).

    Method 6: Determining the frequency by network name (SSID)

    Many routers add suffixes to the network name by default, indicating the frequency. For example:

    • 📶 MyWiFi or MyWiFi_2G — network on 2.4 GHz.
    • 🚀 MyWiFi_5G or MyWiFi-5 — network on 5 GHz.
    • 🔄 MyWiFi_Plus or MyWiFi_Guest - can be any frequency (needs to be checked).

    If you haven't changed the network name, look at the sticker on your router—it often lists both SSIDs. If the name is the same, but the router is dual-band, it's most likely enabled. Smart Connect (see previous section).

    Some providers (eg MTS or Megaphone) configure routers so that networks on different frequencies have the same names but different passwords. In this case:

    1. Try connecting to the network with a different password (usually it is indicated on the router sticker next to the SSID).
    2. If the connection is successful, you are on a different frequency.

    Common problems and solutions

    Sometimes, even after verification, questions remain. Let's look at some typical situations:

    Problem 1: The device does not see the 5 GHz network

    Possible causes and solutions:

    • 📵 The device does not support 5 GHz. Check the specifications on the manufacturer's website (for example, old iPad or budget smartphones can only work at 2.4 GHz).
    • ⚙️ 5 GHz is disabled in the routerGo to settings and enable this range.
    • 📡 Weak 5 GHz signalThis range has poorer penetration through walls. Try moving closer to the router.
    • 🔒 Hidden networkSome routers hide the 5 GHz SSID. Enable visibility in the settings.

    Problem 2: The device automatically connects to 2.4 GHz, although 5 GHz is free

    This is a common problem on Windows And AndroidSolutions:

    • 🖥️ On Windows: open Settings → Network & Internet → Wi-Fi → Manage known networks, select the 2.4 GHz network and press "Forget"The device will now connect to 5 GHz.
    • 📱 On Android: In the Wi-Fi settings, tap on the 2.4 GHz network and select "Delete" or "Forget".
    • 🔄 On router: turn off Smart Connect and separate the networks by giving them different names (eg. MyWiFi_2G And MyWiFi_5G).

    Problem 3: 5GHz speed is slower than 2.4GHz

    It seems paradoxical, but it happens. The reasons are:

    • 📶 Congested channel. Use the app WiFi Analyzerto find a free 5 GHz channel and change it in the router settings.
    • 📡 Weak signal. 5 GHz requires closer proximity to the router. Try using repeater or Mesh system.
    • ⚙️ Suboptimal router settingsSet the channel width 80 MHz (Not 160 MHz, if you have a lot of neighbors).

    FAQ: Frequently Asked Questions about Wi-Fi Frequencies

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

    Yes, if your router is dual-band. Most modern models (TP-Link Archer, Asus RT-AC, Keenetic) support simultaneous operation on both frequencies. You can connect some devices to 2.4 GHz (smart light bulbs, for example) and others to 5 GHz (laptops, smartphones).

    Which range is best for online gaming?

    Recommended for gaming 5 GHz, as it provides lower latency (ping) and a more stable connection. However, if the router is far away and the 5 GHz signal is weak, it is better to use 2.4 GHz with a channel free of interference (e.g. channel 1 or 11).

    Why does my device connect to 2.4GHz even though 5GHz is faster?

    This happens because of the automatic connection algorithms. Many devices (especially on Android) choose a network by signal level, not by speed. To fix this:

    1. Forget the 2.4 GHz network in your device settings.
    2. Reconnect to 5GHz manually.
    3. If your router supports it, disable it. Smart Connect and separate the networks.
    How do I know if my device supports 5GHz?

    Check the specifications on the manufacturer's website or in the documentation. Key points:

    • If standard is specified 802.11a, 802.11ac or 802.11ax — supported.
    • If only 802.11b/g/n - only 2.4 GHz.
    • Smart devices (light bulbs, cameras) usually only work on 2.4 GHz.
    Is it possible to increase the range of the 5GHz signal?

    The 5 GHz range is limited by physical laws, but it can be improved a little:

    • 📡 Use directional antennas (if the router supports them).
    • 🔄 Install repeater or Mesh system (For example, TP-Link Deco).
    • ⚡ Change the channel to a less crowded one (for example, 149–165 in the 5 GHz range).
    • 🏠 Place the router in the center of the apartment, away from walls and metal objects.

    However, it is impossible to completely equalize the range of 5 GHz with 2.4 GHz.
