How to determine the Wi-Fi router range: 2.4 GHz, 5 GHz or 6 GHz?

Have you noticed that some devices connect to your Wi-Fi network faster than others, and video on your phone is constantly lagging, even though your laptop works perfectly? The reason could be frequency range, which your router uses. Modern routers support multiple ranges at once— 2.4 GHz, 5 GHz, and new models and 6 GHz, but not all devices can work with all frequencies. For example, smart light bulbs or older smartphones often "see" only 2.4 GHz, while gaming consoles and flagship phones prefer 5 GHz due to less interference and higher speed.

In this article, you'll learn how to accurately determine which bands your router supports and broadcasts—without complicated technical manipulations. We'll cover methods for different brands (TP-Link, ASUS, Keenetic, MikroTik etc.), including checking through the web interface, mobile apps, and even third-party programs. We'll also find out why a router might be "hiding" one of the bands and how to fix it.

1. What are Wi-Fi bands and why are they important?

Wi-Fi range is frequency channel, which the router uses to transmit data. Three key network parameters depend on it:

• 📶 Coverage range: 2.4 GHz goes through walls better, but slower; 5 GHz faster, but “doesn’t like” obstacles.
• 🚀 Transfer speed: on 5 GHz theoretically it is possible to get up to 1–2 Gbps, whereas 2.4 GHz rarely exceeds 300 Mbit/s.
• 📡 Channel congestion: in apartment buildings 2.4 GHz often overloaded (disturbed by neighbors, microwaves, Bluetooth devices).

Many modern routers support dual band (simultaneously 2.4 GHz And 5 GHz) or even tri-band (added 6 GHz in standard Wi-Fi 6E). However, by default they can only broadcast on one band or use one network name (SSID) for both, which complicates diagnosis.

Important note: If your router supports Wi-Fi 6 (802.11ax), it can automatically switch devices between bands for optimal performance—but only if this feature is enabled in the settings.

2. Method 1: Checking via the router's web interface

The most reliable method is to access your router's control panel. The instructions are universal for most brands, but the settings paths may vary.

1. Connect to the router via cable or Wi-Fi. Use a device that can clearly see both bands (e.g., a laptop or smartphone no older than 5 years).
2. Open your browser and enter the router's IP address in the address bar. Typically, it's:
   • 192.168.0.1 (For TP-Link, D-Link)
   • 192.168.1.1 (For ASUS, Zyxel)
   • my.keenetic.net (For Keenetic)

Log in (default logins/passwords are indicated on the router sticker: usually admin/admin or admin/empty password).

The further path depends on the model:

If there are no separate tabs for 5 GHz, then your router only works on 2.4 GHz. Also pay attention to the field Wireless network standard (or Wireless Mode): if it is indicated there only 802.11b/g/n, That 5 GHz not supported (for 5 GHz should be 802.11a/n/ac/ax).

Channel and channel width (e.g. 40 MHz for 5 GHz)-->

3. Method 2: Analysis via a mobile app

Router manufacturers release official apps that simplify diagnostics. For example:

• 📱 TP-Link Tether (for routers TP-Link)
• 📱 ASUS Router (For ASUS)
• 📱 Keenetic (universal for all models of the brand)
• 📱 MikroTik (for professional devices)

Let's look at an example TP-Link Tether:

1. Connect to your router's Wi-Fi.
2. Open the app and select your router.
3. Go to the section Settings → Wireless.
4. Look at the tabs at the top: if there are any 2.4G And 5G, the router supports both ranges.

In applications ASUS And Keenetic Range information is usually displayed in the section Wi-Fi or NetPlease note:

• 🔹 Network names: if they are different (for example, MyWiFi_2G And MyWiFi_5G), the router broadcasts on both ranges.
• 🔹 Channels: For 2.4 GHz these will be values ​​1–13, for 5 GHz — 36–165.

What should I do if the app doesn't show 5 GHz?

If the app only shows 2.4 GHz, but you are sure that the router supports 5 GHz (according to the model specifications), try:

1. Update the router firmware via the section System → Software Update.

2. Reset to factory settings (System → Reset) and configure again.

3. Check if 5 GHz is disabled manually (sometimes this is done for compatibility with older devices).

4. Method 3: View router specifications by model

If you can't access your router settings (for example, you haven't bought it yet or it's broken), you can determine the supported ranges by device modelsTo do this:

1. Find the router model on the sticker (for example, TP-Link Archer C6, ASUS RT-AX55).
2. Enter the following query into the search engine: [router model] specifications website: manufacturer.ru (For example, ASUS RT-AX55 specifications website: asus.com/ru).
3. Look for lines like this in the characteristics:
   • Dual-band Wi-Fi (2.4 GHz + 5 GHz)
   • Standards: 802.11a/b/g/n/ac/ax (availability a, ac or ax means support 5 GHz).
   • Wi-Fi 6E (support 6 GHz).

Examples of popular models and their ranges:

If the specifications state Single-Band, the router only works on 2.4 GHz. Dual-Band - supports both ranges, Tri-Band — is added 6 GHz (rarely found in household models).

5. Method 4: Using third-party utilities (for Windows, Android, macOS)

If you don't want to mess with your router settings, you can scan your network using specialized software. These programs will show you which bands neighboring routers—including yours—are broadcasting on.

For Windows:

• 🖥️ WiFi Analyzer (from Microsoft Store) - shows all networks around with the range (2.4 GHz or 5 GHz).
• 🖥️ inSSIDer (paid, but trial available) - a professional tool with detailed information about channels and standards.
• 🖥️ NetSpot - builds a heat map of the signal and displays ranges.

For Android:

• 📱 WiFi Analyzer (from farproc) is a free application with a channel load chart.
• 📱 NetX Network Tools - shows the range in the network information.

For macOS:

• 💻 WiFi Explorer — an analogue of inSSIDer for Mac.
• 💻 AirPort Utility (built-in utility) - hold Option (⌥) and click on the Wi-Fi icon in the menu bar, then select Open Wi-Fi diagnostics.

How to use:

1. Connect to your Wi-Fi network.
2. Run the utility and find your network in the list.
3. Look at the column Band (or Frequency): it will be indicated there 2.4 GHz or 5 GHz.
4. If your network is displayed twice, with different ranges, it means the router is broadcasting on both.

Example of display in WiFi Analyzer (Android):

6. Method 5: Checking via the command line (for advanced users)

In Windows and Linux, you can find out the range of a connected network using the command line. This method works if you're already connected to Wi-Fi.

For Windows:

1. Open Command line (Win + R → enter cmd → Enter).
2. Run the command:

   netsh wlan show interfaces

3. Find the line Radio type (Radio type). It will indicate:
   • 802.11n - more likely, 2.4 GHz (but it could be 5 GHz depending on the router).
   • 802.11ac or 802.11ax — 5 GHz (or 6 GHz For ax).

For Linux (Ubuntu/Debian):

1. Open Terminal (Ctrl + Alt + T).
2. Run the command:

   iwlist wlan0 frequency

   (replace wlan0 to your network interface, if necessary).

3. Look at the frequency list. If there are values ​​like 5.180 GHz, the router supports 5 GHz.

For macOS:

1. Open Terminal (Applications → Utilities → Terminal).
2. Run the command:

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

3. In the column CHANNEL look at the channel number:
   • 1–13 — 2.4 GHz.
   • 36–165 — 5 GHz.

If the command line only shows 2.4 GHz, but are you sure the router supports it? 5 GHz, check:

• 🔹 Are you connected to the correct network (sometimes the router creates two networks with different names).
• 🔹 Is it enabled? 5 GHz in the router settings (see Method 1).

How do I find out what band a particular device is using?

If you need to check what band a specific device (such as a smartphone or TV) is connected to, use:

- On Android: application WiFi Analyzer → tab Connection.

- On iOS: Go to Settings → Wi-Fi, tap on the network name - if there is an inscription 5 GHz, which means the device is connected to this range.

- On Windows: command netsh wlan show interfaces (see above).

7. Why your router may not show 5 GHz (and how to fix it)

You have tried all the methods, but 5 GHz Still haven't found it? Here are some possible causes and solutions:

The problem is especially common with 5 GHz occurs in users who:

• 🔹 Bought a router from a provider (for example, Rostelecom or Beeline) - operators sometimes block 5 GHz "for stability."
• 🔹 Use the router in repeater mode - not all repeaters support this 5 GHz.
• 🔹 If you live in an apartment building with a lot of interference, your router may automatically turn off. 5 GHz, if the channel is overloaded.

8. How to improve Wi-Fi performance by knowing the ranges

Now that you know what bands your router supports, you can optimize your network:

• 🛠️ Divide the networks: give different names (SSID) For 2.4 GHz And 5 GHz (For example, MyWiFi_2G And MyWiFi_5G). This will allow you to manually select the range on devices.
• 📶 Choose the right channel:
  • For 2.4 GHz: Use channels 1, 6 or 11 (they do not overlap).
  • For 5 GHz: choose channels 36-48 or 149-165 (they are less crowded).
• 🔄 Turn on Smart Connect (if supported by the router): The router will automatically switch devices between bands for better speed.
• 🚫 Disable outdated standards: in the settings 2.4 GHz turn it off 802.11b (This will speed up the network for modern devices).

An example of optimal settings for a router ASUS RT-AX55:

• 🔹 2.4 GHz: channel 6, width 20 MHz, standard 802.11n/g (disable b).
• 🔹 5 GHz: channel 36, width 80 MHz, standard 802.11ac/ax.
• 🔹 Smart Connect: enable (if automatic switching is required).

If you have a lot of devices that only work on 2.4 GHz (smart home, older gadgets), but you want maximum speed on your main devices, configure your router like this:

1. Create two separate networks with different names.
2. Connect smart devices to 2.4 GHz, and smartphones/laptops - to 5 GHz.
3. Set traffic priority (QoS) For 5 GHz in the router settings.

1. Does the device support Wi-Fi 6E (for now these are only flagship smartphones and laptops from 2022+).

2. Is the 6 GHz band permitted in your country (in Russia it is not yet certified for home use).

3. Is the router firmware updated to the latest version?-->

FAQ: Frequently Asked Questions about Wi-Fi Bands

My router supports 5 GHz, but my phone can't see it. What's wrong?

Possible reasons:

• 📵 Your smartphone does not support 5 GHz (check model specifications).
• 🔧 It's disabled in the router 5 GHz or it works in mode 802.11a, which not all devices support.
• 📡 Channel 5 GHz It's set to DFS (dynamic frequency assignment), which some phones don't like. Try manually setting channels 36–48.

Solution: Go to your router settings and turn it on. 5 GHz with support 802.11n/ac, select a fixed channel (for example, 36).

Which band is better for online gaming: 2.4GHz or 5GHz?

For games, definitely. 5 GHz, because:

• 🎮 Less lag (ping) due to less channel congestion.
• 🚀 More stable speed (important for multiplayer games).

Exception: If your PC/console is far from the router and the signal 5 GHz weak, better to use 2.4 GHz (but then it’s better to play via cable).

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

Yes, if the router supports it dual band (most modern models). In this case:

• 🔄 You can broadcast under one name (SSID) with the function Smart Connect (the router itself distributes devices).
• 📛 Or create two separate networks (for example, MyWiFi_2G And MyWiFi_5G) for manual selection.

Both ranges will work simultaneously, no problem.
