How to determine your Wi-Fi frequency: 2.4 or 5 GHz – working with your router and devices

When it comes to wireless network speed and stability, Wi-Fi hertz The frequency (2.4 or 5 GHz) plays a key role. This parameter determines how quickly pages load, the ping in games, and even the signal coverage in your home. But how do you know which frequency your router or connected device uses? This article will help you figure it out without any technical difficulties.

Many users mistakenly think that Hertsovka — this is a router-specific characteristic. In fact, it can (and should!) be checked both on the signal source (router) and on client devices: smartphones, laptops, Smart TVs. We'll cover all the relevant methods—from standard settings to specialized utilities—and explain why sometimes Even when connected to 5 GHz, the device can automatically switch to 2.4 GHz (and how to avoid it).

Important: If you are setting up a network for online games, 4K streaming Whether you're working with large files or connecting to a network, knowing your current frequency will help optimize your connection. For example, 5 GHz offers faster speeds but is less effective at penetrating walls, while 2.4 GHz is more stable over distance but is susceptible to interference from neighbors.

1. How to check the Wi-Fi frequency on a router

Let's start with the signal source. Most modern routers support dual mode (2.4 + 5 GHz), but it's not always clear which network is currently active. There are three reliable methods:

Method 1: Via the router's web interface

  1. Connect to the router's network (via Wi-Fi or cable).
  2. Open your browser and enter the IP address of your device. This is usually 192.168.0.1, 192.168.1.1 or 192.168.8.1 (check the sticker on the body).
  3. Enter login/password (by default it is often admin/admin).
  4. Go to the section Wireless network or Wi-FiThere should be separate tabs for 2.4 GHz and 5 GHz.

Method 2: Via a mobile app

Manufacturers like TP-Link, ASUS or Keenetic offer official applications for managing the router. For example, in Tether (for TP-Link) the frequency is displayed in the section Wi-Fi → Network SettingsAdvantage: no need to remember the IP address.

Method 3: By network name (SSID)

Many routers create two networks with different names by default, for example:

  • 📶 Keenetic-1234 — 2.4 GHz
  • 📶 Keenetic-1234_5G — 5 GHz

If the names match, check the settings in the web interface (see Method 1).

2. Determination of hertz on Windows 10 and 11

On computers with Windows There are several ways to find out your current connection frequency. The easiest one is through Task Manager:

  1. Click Ctrl + Shift + Escto open Task Manager.
  2. Go to the tab Performance → Wi-Fi.
  3. The frequency will be indicated in the upper right corner (for example, 2.4 GHz or 5 GHz).

If this method does not work (for example, on older versions of Windows), use command line:

netsh wlan show interfaces

Find the line in the results Radio type (Radio Type). Values:

  • 📡 802.11n - can work on both frequencies (needs clarification)
  • 📡 802.11ac or 802.11ax - only 5 GHz
  • 📡 802.11g or 802.11b - only 2.4 GHz

For accuracy, check the network properties:

  1. Open Settings → Network and Internet → Wi-Fi.
  2. Click on the current network → Properties.
  3. Scroll to the block Network properties — the frequency will be indicated there.

3. Check on macOS (MacBook, iMac)

On devices Apple You can determine your hertz without third-party utilities. Here are the step-by-step instructions:

  1. Hold down the key Option (⌥) and click on the Wi-Fi icon in the top bar.
  2. The drop-down menu will display extended information, including the line Channel (channel).
  3. If the channel is from 1 to 13 — this is 2.4 GHz. Channels 36–165 refer to 5 GHz.

For more detailed information:

  1. Open System Preferences → Network.
  2. Select an active Wi-Fi connection → Additionally.
  3. In the tab Wi-Fi Find your current network and look at the column Channel.

On macOS Ventura and newer, the interface has changed slightly, but the logic remains the same. If the Wi-Fi icon doesn't display the channel when held down Option, update your system or use Wireless Diagnostics (built-in utility, runs via Spotlight upon request Wireless diagnostics).

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

In rare cases, this is related to the adapter drivers. Try connecting to a different network or resetting the network settings. System Preferences → Network → Manage Networks.

4. How to find out the frequency on an Android smartphone

On Android There's no universal method—it all depends on the system version and manufacturer. Let's look at some working methods:

Method 1: Via Wi-Fi settings (for stock Android and most brands)

  1. Open Settings → Wi-Fi.
  2. Tap on the current network (don't disconnect!).
  3. Scroll down to the block Network information or Additionally.
  4. Look for the line Frequency, Range or Standard (For example, 802.11ac means 5 GHz).

Method 2: Analyzer applications

If there is no information in the settings, install one of the applications:

  • 📱 WiFi Analyzer (from farproc) - shows the frequency in real time.
  • 📱 Network Analyzer — displays the channel and standard (2.4/5 GHz).
  • 📱 Fing — determines the hertz for connected devices.

Method 3: For Xiaomi, Samsung, and Huawei devices

On smartphones of these brands, the frequency may be hidden in the engineering menu:

  1. Open the app Telephone.
  2. Enter the code ##4636##.
  3. Select Wi-Fi Information.
  4. In the block Wi-Fi signal the frequency will be indicated.

5. Check on iPhone and iPad

Method 1: Via Airport Utility app (official method)

  1. Download Airport Utility from the App Store (free).
  2. Open the app and tap on the icon Wi-Fi Scan in the upper right corner.
  3. Click Scan and wait for the scanning to complete.
  4. In the list of networks, find yours and look at the column Band (2.4 GHz or 5 GHz).

Method 2: Via Shortcuts (for advanced users)

If you are familiar with automation, you can create label, which will display network information. To do this:

  1. Open the app Shortcuts.
  2. Create a new shortcut with an action Get Wi-Fi Details.
  3. Add an action Show Result.
  4. Run the shortcut - the results will contain the line SSID BSSID, where the frequency is indicated.

Please note: on iOS 17 and newer Apple may block access to some data via Shortcuts. In this case, the only option left is Airport Utility.

6. Determining the Hertz on Smart TV and other devices

On Smart TV (Samsung, LG, Sony) and other gadgets (set-top boxes, cameras), frequency testing depends on the model. General recommendations:

For Samsung TVs (Tizen OS):

  1. Open Settings → General → Network → Open network settings.
  2. Select your current Wi-Fi network → Additional settings.
  3. There will be a line in the connection information Frequency or Range.

8. Common problems and solutions

When working with different frequencies, users encounter typical difficulties. Let's look at the most common ones:

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

  • 🔍 Check if the 5 GHz band is enabled on your router (in the settings) Wireless → 5 GHz).
  • 🔍 Make sure your device supports 5 GHz (see table above).
  • 🔍 Try changing the channel on your router (for example, from 149 on 36).

Problem 2: Constantly switching between 2.4 and 5 GHz

This is due to the function Band Steering (at ASUS, TP-Link) or Smart Connect (at Keenetic). Solutions:

  • 🔄 Turn it off Band Steering in the router settings.
  • 🔄 Divide the networks into two different ones (for example, MyWiFi_2G And MyWiFi_5G).
  • 🔄 Update your router firmware.

Problem 3: Slow speed on 5 GHz

Reasons and solutions:

  • 📉 Interference from other networks: use an analyzer (eg. WiFi Analyzer) and select a free channel.
  • 📉 Weak signal: 5 GHz has poor penetration through walls—move your device closer to the router.
  • 📉 Outdated firmware: Update your router software and adapter drivers on your PC.
⚠️ Attention: Router settings may vary depending on the model and firmware version. If you can't find the required option in the web interface, consult your model's manual or contact the manufacturer's support team.
⚠️ Attention: Some devices (such as smart plugs or security cameras) only operate on 2.4 GHz. If you disable this band on your router, they will lose connection.

FAQ: Answers to Frequently Asked Questions

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

Yes, most modern routers support it. dual modeYou can enable both bands simultaneously, and devices will connect to them independently. Some routers (for example, ASUS RT-AX88U) even allow you to combine networks under one name (SSID) with automatic frequency selection (Smart Connect).

How to force a connection to 5 GHz if the device is stuck on 2.4 GHz?

There are several ways:

  1. Separate the networks on your router by giving them different names (for example, MyWiFi_2G And MyWiFi_5G).
  2. Disable 2.4 GHz in your router settings (if you don't use devices that only operate on this frequency).
  3. On Windows/Android, manually select the 5 GHz network from the list of available networks.

On iPhone Forced connection to 5 GHz is not possible - the device selects the range itself.

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

For games 5 GHz is definitely recommended, because:

  • Less latency (ping).
  • More bandwidth (important for multiplayer games).
  • Less interference from other devices.

Exception: if your PC/set-top box is located far from the router and the 5 GHz signal is weak, it is better to stay on 2.4 GHz, but use a wired connection (Ethernet).

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

It's paradoxical, but possible reasons:

  • 🔌 Interference on the 5 GHz channel (check in WiFi Analyzer and change the channel).
  • 🔌 Weak signal (5 GHz is worse at passing through obstacles).
  • 🔌 Outdated router firmware or adapter driver.
  • 🔌 Restrictions from the provider (rare, but it happens).

Solution: Move the device closer to the router and test the speed again. If the problem persists, try updating the firmware.

How do I know which channel is best for 5GHz?

The optimal channel depends on the airtime load. To choose the best one:

  1. Install the application on your smartphone WiFi Analyzer.
  2. Run the scan in mode Channel Rating.
  3. Select the channel with the least load (green zone).
  4. In the router settings, set this channel manually (automatic selection is not always optimal).

For 5 GHz, the recommended channels are 36–48 (lower range) or 149–165 (high range, but may not be supported by some devices).
