How to Find Your Wi-Fi Frequency (2.4 or 5 GHz): A Complete Guide for All Devices

You've connected to Wi-Fi, but you're not sure if the network is working on the frequency you're using. 2.4 GHz or 5 GHzThis information is critical for connection stability: 5 GHz is faster, but has poorer penetration through walls, while 2.4 GHz is slower but covers a larger area. In some cases, devices (such as smart light bulbs or older printers) only work on 2.4 GHz, and modern smartphones and laptops support both frequencies.

In this article you will find All current methods for checking Wi-Fi frequency — from viewing router settings to analyzing network parameters on different devices. We'll cover methods for Windows 10/11, macOS, Android, iOSWe'll also show you how to determine the frequency using mobile apps and specialized utilities. Whether you're setting up a network for a game console, TV, or smart home system, there are solutions for all scenarios.

1. How to find out the Wi-Fi frequency through the router settings

The most reliable way is to go to the router's web interface and look at the wireless network settings. Most modern models (TP-Link, ASUS, Keenetic, MikroTik) display the frequency in the section Wireless or Wi-Fi.

Instructions:

• 🌐 Open your browser and enter the router's IP address (usually 192.168.0.1, 192.168.1.1 or 192.168.8.1). The address can be found on the sticker on the device body.
• 🔑 Enter your login and password (by default it is often admin/admin or admin/password).
• 📡 Go to the section Wireless network (or Wi-Fi, Wireless Settings).
• 🔍 Find the parameter Band, Channel Width or Frequency. It will be indicated there 2.4 GHz or 5 GHz.

On some routers (for example, Xiaomi or Tenda) the frequency can be hidden behind the option Opening hours (Wireless Mode). If the settings indicate 802.11b/g/n - This 2.4 GHz, A 802.11a/n/ac/ax — 5 GHz.

Channel number (1-14 — 2.4 GHz, 36-165 — 5 GHz)|Channel width (20/40 MHz for 2.4 GHz, 40/80/160 MHz for 5 GHz)|Operating mode (802.11ac = 5 GHz)|Network name (the SSID often includes an indication of the frequency, for example, "_5G")

-->

⚠️ Attention: On dual-band routers there may be both frequencies are turned on simultaneously under different names (SSID). For example, MyWiFi_2G And MyWiFi_5GIf you're connected to a network without a frequency in its name, check your device's connection settings.

2. Determining the Wi-Fi frequency on Windows 10 and 11

In operating systems Windows 10 And Windows 11 You can find out the Wi-Fi frequency without third-party programs - through command line or task manager.

Method 1: Via Command Prompt (CMD)

1. Click Win + R, enter cmd and press Enter.
2. Enter the command:

   netsh wlan show interfaces

3. Find the line Channel (channel) in the section Radio TypeIf the channel is from 1 to 14 - This 2.4 GHz, If 36 and above — 5 GHz.

Method 2: Via Task Manager

• 🖥️ Click Ctrl + Shift + Escto open Task Manager.
• 📊 Go to the tab Performance → Wi-Fi.
• 📶 The frequency will be indicated in the upper right corner (2.4 GHz or 5 GHz).

Windows 10|Windows 11|macOS|Linux|I don't know-->

If the frequency is not displayed in the task manager, try updating the network adapter drivers via device Manager (Win + X → device Manager → Network adapters).

3. Checking the frequency on macOS (MacBook, iMac)

On devices Apple (MacBook, iMac, Mac mini) You can find out the Wi-Fi frequency through system report or utility Airport Utility.

Method 1: Via "System Report"

• 🍎 Click on the logo Apple in the top menu → About this Mac → System report.
• 📄 In the left menu, select Net → Wi-Fi.
• 🔍 In the right part of the window, find the line Channel (channel). Just like on Windows, 1-14 - This 2.4 GHz, 36+ — 5 GHz.

Method 2: Via Terminal (for advanced users)

1. Open Terminal (through Spotlight or Programs → Utilities).
2. Enter the command:

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

3. Find the line channel. For example, channel: 6 - This 2.4 GHz, A channel: 149 — 5 GHz.

4. How to check the Wi-Fi frequency on an Android smartphone

On Android There is no built-in way to see the Wi-Fi frequency, but there are a few workarounds: via developer settings, third-party applications or router data.

Method 1: WiFi Analyzer App (Recommended)

• 📱 Install the application WiFi Analyzer (from farproc) from Google Play.
• 📊 Open the tab List of access points (Access Points).
• 🔍 Find your network in the list. In the column Channel the channel will be indicated, and in Band — frequency (2.4 GHz or 5 GHz).

Method 2: Via developer settings (not available on all devices)

1. Activate developer mode: go to Settings → About phone → Build number and press 7 times.
2. Return to Settings → System → Developer Options.
3. Find the option Debugging over Wi-Fi or Wi-Fi Information (on some firmware versions).
4. It may display the frequency or channel (for example, Channel: 1 (2.4 GHz)).

Why doesn't Android have a built-in frequency display?

Smartphone manufacturers hide this information to simplify the interface for regular users. Furthermore, Android doesn't standardize the display of network parameters—each brand (Samsung, Xiaomi, Google) can implement it differently.

If none of the methods worked, check the frequency through the router settings (section 1) or connect to the network from another device (for example, a laptop).

5. Checking the frequency on iPhone and iPad (iOS)

On iPhone And iPad company Apple does not provide direct access to Wi-Fi frequency information. However, there are indirect methods:

Method 1: Via Airport Utility app (hidden feature)

• 📲 Install the official app Airport Utility from App Store.
• 🔧 Turn on Wi-Fi scanner mode:
  1. Close the app (swipe up).
  2. Press and hold the icon Airport Utility → select Wi-Fi Scanner.

🔍 Find your network in the list and look at the column Band (2.4 GHz or 5 GHz).

Method 2: Via a short code (only for some router models)

Some routers (eg. Apple AirPort) allow you to see the frequency through the web interface. If your router supports 802.11k, iPhone can automatically connect to the optimal frequency, but this will not help determine it.

⚠️ Note: There's no reliable way to find out your Wi-Fi frequency on iOS without additional devices or access to the router. If knowing this information is critical, use a laptop or Android smartphone.

6. Determining the frequency on Smart TV and other devices

Smart TVs (Samsung, LG, Sony, Xiaomi) and other gadgets (set-top boxes, printers) often don't display the Wi-Fi frequency in the interface. Here's what you can do:

For Smart TV:

• 📺 On Samsung And LG go to Settings → Network → Network StatusSometimes there is a section there Additionally with information about the channel.
• 🔧 On Android TV (For example, Xiaomi Mi TV or Sony Bravia) install the application WiFi Analyzer from Google Play (if supported).

For game consoles (PS5, Xbox, Nintendo Switch):

• 🎮 On PlayStation 5 And Xbox Series X/S The frequency is not displayed. Check your router settings or use a laptop to analyze the network.
• 🏠 Nintendo Switch supports only 2.4 GHz (except for the model Switch OLED, which can operate at 5 GHz in a docking station).

For printers and MFPs:

Most printers (HP, Canon, Epson) work only on 2.4 GHzIf your device isn't connecting to Wi-Fi, check if you're trying to connect it to the network. 5 GHz (for example, if the router distributes two networks with the same name).

7. Programs for analyzing Wi-Fi networks (advanced level)

If you need to not only find out your network frequency but also analyze neighboring access points, use specialized utilities:

For Windows:

• 🖥️ inSSIDer — shows all networks within range, their frequencies, channels and signal strength.
• 📊 NetSpot — creates a heat map of Wi-Fi coverage and displays frequencies.
• 🔧 Wireshark - for deep packet analysis (requires skills).

For macOS:

• 🍎 WiFi Explorer - analogue inSSIDer for Mac.
• 📈 NetSpot (cross-platform solution).

For Android:

• 📱 WiFi Analyzer (from farproc) - free and simple.
• 🔍 NetX Network Tools - advanced network analysis.

These programs are useful if you are setting up a network for smart home, online games or streaming video and want to avoid interference from neighboring routers.

8. Common mistakes and how to avoid them

When determining the Wi-Fi frequency, users often encounter typical problems:

1. The router distributes two networks with the same name (SSID).

   Solution: Rename the networks in the router settings by adding suffixes _2G And _5G (For example, MyWiFi_2G And MyWiFi_5G).

2. The device automatically switches between frequencies.

   Solution: Disable the function in your router settings. Band Steering (range control), if any.

3. Frequency is not displayed on iPhone or Android.

   Solution: Use another device (laptop) or check your router settings.

4. After changing the frequency, the device does not connect.

   Solution: Make sure that the device supports the selected frequency (for example, older gadgets may not work on 5 GHz).

⚠️ Attention: If you change the frequency on your router (for example, with 5 GHz on 2.4 GHz), all connected devices will be disconnected and will require you to re-enter the password.

If after all manipulations the frequency is still not detected, try:

• 🔄 Reboot the router (turn it off for 30 seconds).
• 📶 Bring the device closer to the router (sometimes a weak signal prevents the correct determination of parameters).
• 🔧 Update the router firmware (via the web interface in the section System Tools or Administration).

FAQ: Answers to Frequently Asked Questions

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

Yes, if the router supports it dual-band (dual-band mode). In this case, it distributes two separate networks, and you can connect to either one. On some models (ASUS RT-AX88U, TP-Link Archer C6) you can enable the function Smart Connect, which automatically distributes devices by frequencies.

Why can't my device see the 5 GHz network?

Possible reasons:

• The device does not support 5 GHz (relevant for old smartphones, printers, smart lamps).
• The range is disabled in the router settings. 5 GHz.
• The channel width on the router is set to 160 MHz, and the device only supports 80 MHz or 40 MHz.

Solution: Check your router settings and device specifications.

Which 2.4 GHz channel is best to choose to minimize interference?

On frequency 2.4 GHz channels 1, 6 And 11 do not intersect with each other. Use the program WiFi Analyzerto see which channels are occupied by neighboring networks and select the least busy one.

Does Wi-Fi frequency affect internet speed?
Yes, but not directly. 5 GHz provides higher speed (up to 1 Gbps and higher), but has a shorter range. 2.4 GHz slower (up to 150–300 Mbps), but it passes through walls better. Actual speed also depends on:
• Your provider's tariff plan.
• Number of connected devices.
• Interference from other networks.
Is it possible to change the Wi-Fi frequency on a public router (in a cafe, hotel)?

No, on public networks, router settings are locked for users. You can only connect to an available frequency. If you need a specific frequency (for example, 2.4 GHz (for smart watches), check with the establishment's administrator what network their equipment distributes.
