How to check whether your Wi-Fi router operates on 2.4 GHz or 5 GHz?

Have you noticed that some devices connect to your Wi-Fi faster than others, while the internet speed on your smartphone and laptop can differ significantly? The reason is often operating frequency of the routerModern routers support two ranges: 2.4 GHz (long-distance, but busy) and 5 GHz (fast, but with a smaller coverage area). Knowing your current frequency will help you optimize your network, eliminate interference, or select the best channel for a stable connection.

In this article you will find All current methods for checking Wi-Fi frequency, including hidden methods for devices without access to the web interface. We'll cover step-by-step instructions for popular brands (TP-Link, ASUS, Keenetic, MikroTik), as well as universal solutions via smartphone or computer. We'll pay special attention to nuances that manufacturers often gloss over—for example, why a router might automatically switch between frequencies and how to disable it.

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

The chosen range affects not only the internet speed but also the stability of the connection. Here are the key differences between 2.4 GHz And 5 GHz:

• 📶 2.4 GHz: Better through walls, but susceptible to interference from nearby networks, microwaves, and Bluetooth devices. Maximum speed is up to 600 Mbps (theoretically).
• ⚡ 5 GHz: less interference, higher speed (up to 1.3 Gbps and higher), but the signal fades faster over distance and through obstacles.
• 🔄 Dual-band routers: can broadcast both networks simultaneously (for example, MyWiFi_2G And MyWiFi_5G), but not all devices support 5 GHz.

If your router is running on 2.4 GHz, and there are a dozen other networks on the same channel nearby, the speed can drop by 5-10 times! Switching to 5 GHz Changing the channel often solves the problem. But first, you need to check your current settings.

⚠️ Note: Some older devices (such as printers, smart light bulbs, or game consoles) may only support 2.4 GHzIf you switch the router to 5 GHz, they will lose connection.

Method 1: Checking via the router's web interface (universal method)

The most reliable way is to access your router's control panel. To do this:

1. Connect to your router's Wi-Fi network (or use an Ethernet cable).
2. Open your browser and enter your router's IP address in the address bar. This is usually:
   • 192.168.0.1 (For TP-Link, D-Link)
   • 192.168.1.1 (For ASUS, Keenetic)
   • 192.168.8.1 (for some models Huawei)

Enter your login and password (by default it is often admin/admin or indicated on the router sticker).

The next steps depend on your router model. Below are instructions for popular brands.

Brand-Specific Instructions

If your router has two bands active at the same time, you will see two sections with settings - for example, Wi-Fi 2.4GHz And Wi-Fi 5GHzIn this case, the router broadcasts both networks, and devices connect to them independently.

⚠️ Attention: On some routers (for example, Zyxel Keenetic) The frequency can be switched automatically in Smart Wi-Fi mode. To disable this, find the option Smart Connect and deactivate it.

Reset the router using the Reset button (hold for 10 seconds)|

Method 2: Checking via a mobile app

Router manufacturers release official apps for managing your network from your smartphone. This is convenient if you don't want to access the web interface. Examples of apps:

• 📱 TP-Link Tether (for routers TP-Link)
• 📱 ASUS Router (For ASUS)
• 📱 Keenetic (For Zyxel Keenetic)
• 📱 Mi Wi-Fi (for routers Xiaomi)

Verification algorithm:

1. Install the app from App Store or Google Play.
2. Connect to the router's network.
3. Register or log in to your account (if required).
4. Find the "Wi-Fi" or "Wireless Network" section. The frequency is usually listed next to the network name or in the advanced settings.

In the appendix Keenetic, for example, the frequency is displayed in the section Wi-Fi → Hotspot in the "Standard" field. For TP-Link Tether — in the section Settings → Wireless.

Method 3: Determining the frequency through the operating system (without access to the router)

If you don't have access to your router settings (for example, you're connected to someone else's network), you can find out the frequency using your operating system's tools. Let's look at the options for Windows, macOS, Android And iOS.

On Windows 10/11

Open Command line (Win + R → enter cmd → Enter) and run the command:

netsh wlan show interfaces

Find the line in the results Radio type. Possible values:

• 802.11n or 802.11g — 2.4 GHz
• 802.11ac or 802.11a — 5 GHz

On macOS

Hold down the key Option (⌥) and click on the Wi-Fi icon in the menu bar. The frequency information will appear in the drop-down list (Channel). If the channel is from 1 to 14 - This 2.4 GHz, if higher (for example, 36, 44) — 5 GHz.

On Android

Install the application Wi-Fi Analyzer (or similar) from Google PlayIt will show all available networks and their frequencies. Your network will be marked as connected, with the band next to it (2.4 GHz or 5 GHz).

On iPhone/iPad

Apple does not provide built-in tools for viewing Wi-Fi frequencies. Use third-party utilities, such as AirPort Utility (requires enabling the mode) Wi-Fi Scanner in the application settings).

⚠️ Attention: On iOS It's impossible to determine the frequency without additional apps. Some routers also hide frequency information for security reasons (for example, on public networks).

Method 4: Analyzing the Wi-Fi network name

Many routers add a suffix to the network name by default, indicating the frequency. Examples:

• 🔍 MyWiFi_2G or MyWiFi-2.4 — 2.4 GHz
• 🔍 MyWiFi_5G or MyWiFi-5 — 5 GHz
• 🔍 MyWiFi_PLUS — often means 5 GHz (at ASUS)

If the network name does not contain any explicit indication, this does not mean that the router only works on 2.4 GHz. It is possible that both networks are broadcast under the same name (mode Smart Connect), and devices automatically connect to the optimal range.

How do I know if Smart Connect is enabled?

In the router's web interface, find the option Smart Connect, Band Steering or Smart Wi-FiIf enabled, the router automatically distributes devices between 2.4 and 5 GHz. This can cause problems if one of the devices doesn't support 5 GHz—it simply won't connect to the network.

Method 5: Using third-party utilities to analyze the network

If the previous methods don't work, use specialized programs. They will not only show the frequency but also help optimize the network.

• 🖥️ inSSIDer (Windows/macOS) - shows all networks around, their frequencies, channels and signal strength.
• 📱 WiFi Analyzer (Android) - visualizes channel load.
• 🖥️ Acrylic Wi-Fi (Windows) - professional diagnostic tool.

Example of a report in inSSIDer:

SSID:         MyWiFi
BSSID:        AA:BB:CC:DD:EE:FF
Channel:      6 (2.4 GHz)
Signal:       -55 dBm
Security:     WPA2-PSK

Here Channel: 6 (2.4 GHz) clearly indicates the range.

Common problems and their solutions

Checking your Wi-Fi frequency can be tricky. Let's look at some common issues and how to resolve them.

Problem 1: The router does not show the frequency in the settings

Some firmware (especially on older models) hides frequency information. Solutions:

• Update your router firmware via the web interface.
• Use third-party utilities (see Method 5).
• Check the network name - sometimes the frequency is encrypted in it (for example, MyWiFi_N = 2.4 GHz, MyWiFi_AC = 5 GHz).

Problem 2: The device does not see the 5 GHz network

Possible reasons:

• The device does not support 5GHz (check specifications).
• The 5 GHz band is disabled in the router (enable it in the settings).
• The distance to the router is too great - 5 GHz passes through walls worse.

Problem 3: The router automatically switches frequencies

Function Smart Connect or Band Steering may interfere. To disable it:

1. Go to the router's web interface.
2. Search section Wi-Fi → Smart Connect (the name may differ).
3. Disable the feature and save the settings.

⚠️ Attention: On some routers (ASUS, Netgear) shutdown Smart Connect leads to the division of the network into two separate ones (for example, MyWiFi_2G And MyWiFi_5G). Please note that devices will not automatically switch between them.

FAQ: Frequently Asked Questions

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

Yes, if your router is dual-band. In the settings, you'll see two sections for each frequency. You can enable both networks by assigning them different names (for example, MyWiFi_2G And MyWiFi_5G). Devices will connect to them independently.

How do I know if my device supports 5GHz?

Check the device specifications on the manufacturer's website. You can also try connecting to a 5 GHz network—if the device "sees" it, then it supports it. Windows run the command netsh wlan show drivers and find the line Supported radio types. If there is one there 802.11a or 802.11ac, then 5 GHz is supported.

Which frequency is best for gaming or streaming?

For online gaming and video streaming 4K preferable 5 GHz — there's less interference and higher speed. However, if the router is far away and the walls are thick, 2.4 GHz It might be more stable. Try both options and test the ping (for example, using the command ping google.com -t).

Why is the speed on 5 GHz lower than on 2.4 GHz?

This is paradoxical, but possible for several reasons:

• Weak 5GHz signal due to distance or obstacles.
• The device is connected to 5 GHz but is using a narrow channel (eg. 20 MHz instead of 80 MHz).
• The Wi-Fi adapter driver is out of date (please update it).
• The router has compatibility mode enabled, which limits the speed.

Check the channel settings in your router and try setting the width manually. 40 MHz or 80 MHz for 5 GHz.

Is it possible to change the Wi-Fi frequency on a router?

Yes, if your router supports both bands. In the web interface, find the section Wi-Fi or Wireless network and select the desired range (2.4 GHz or 5 GHz). Please note that after changing the frequency, some devices may lose connection if they do not support the selected range.
