How to find out your Wi-Fi network frequency: 2.4 GHz or 5 GHz – a detailed guide

You've connected to Wi-Fi, but you don't know if the network is working at the frequency you're using. 2.4 GHz or 5 GHzThis information is critical for connection stability: the frequency affects internet speed, coverage range, and even device compatibility. For example, smart light bulbs or older laptops often only support 2.4 GHz, and modern smartphones and TV set-top boxes work better on 5 GHz.

In this article you will find 5 Proven Ways to Determine Your Wi-Fi Frequency — from built-in operating system tools to analyzing router settings. We'll also compare the advantages of each band and provide recommendations on when to switch between them. If your internet is slow or frequently drops, the cause may be an incorrectly selected frequency.

Why is it important to know your Wi-Fi network frequency?

Ranges 2.4 GHz And 5 GHz fundamentally differ in characteristics. The first one provides greater signal range (passes through walls and ceilings), but suffers from channel congestion — especially in apartment buildings where neighbors use the same frequencies. The second range offers high speed and less interference, but the signal fades faster at a distance.

Here are the key differences:

⚠️ Attention: If your router supports Wi-Fi 6 (802.11ax), it can use both ranges simultaneously (technology Dual-Band or Tri-Band). In this case, the network can automatically switch between frequencies, but some devices become stuck on a less optimal range.

Method 1: Checking Wi-Fi Frequency on Windows 10/11

In operating systems Windows 10 And Windows 11 You can find out the network frequency without third-party programs. To do this:

1. Click the Wi-Fi icon in the lower right corner of the taskbar (next to the clock).
2. Select the connected network and click Properties (or Network parameters in Windows 11).
3. Scroll down to the block Properties - there will be a line Protocol (For example, Wi-Fi 5 (802.11ac)).

If the protocol states:

• 🔹 802.11b/g/n - This 2.4 GHz.
• 🔹 802.11a/n/ac/ax - This 5 GHz (or 6 GHz for Wi-Fi 6E).

⚠️ Attention: In Windows 11 after the 2023 Update, the path to network properties has changed. If you don't see the section Protocol, open Settings → Network & Internet → Wi-Fi → Manage known networks, select your network and click Properties.

An alternative method is through command line:

1. Launch Command line (click Win + R, enter cmd).
2. Enter the command:

   netsh wlan show interfaces

3. Find the line Radio type (Radio type). Meaning 802.11n or 802.11g means 2.4 GHz, and 802.11ac — 5 GHz.

Method 2: Determining the frequency on an Android smartphone

On Android The default settings rarely show the Wi-Fi frequency, but there are workarounds:

Method 1: Through settings (for some models)

On smartphones Samsung, Xiaomi And Google Pixel:

1. Open Settings → Wi-Fi.
2. Tap on the name of the connected network.
3. Look for the line Frequency, Range or Standard (For example, 5 GHz, 802.11ac).

🔹 If there is no such line, proceed to the next method.

Method 2: Wi-Fi Analyzer App

Install the free app Wi-Fi Analyzer (from farproc) or NetSpot:

1. Open the app and go to the tab AP list (list of access points).
2. Find your network in the list - in the column Band will be indicated 2.4 GHz or 5 GHz.

⚠️ Attention: On some devices (eg. Huawei or Honor) Wi-Fi analysis applications may require location permissionsThis is due to limitations in Android 10+. If you deny access, the app won't show frequencies.

Why does Android hide Wi-Fi frequency?

Manufacturers often simplify the settings interface by removing "technical" details. Furthermore, some countries (such as the EU) restrict the display of radio frequency information in the user interface due to regulatory requirements.

Method 3: Check on iPhone or iPad

On devices Apple (iOS/iPadOS) default settings They don't show the Wi-Fi frequency.There are two workarounds:

Method 1: Through the Airport Utility app

Download the official app Airport Utility from the App Store (even if you don't have an Apple router):

1. Install and open the application.
2. Click Wi-Fi Scan in the upper right corner.
3. Turn on scanning - in a few seconds a list of networks with a speaker will appear Band.

Method 2: Via a router (if iPhone is connected)

If you have access to your router settings:

1. Open the router's web interface (usually at 192.168.0.1 or 192.168.1.1).
2. Check the list of connected devices - your iPhone may have a range listed next to it (for example, 5G or 2.4G).

🔹 On MacBook The frequency is displayed more easily: hold Option (⌥) and click on the Wi-Fi icon in the menu bar - more information will appear, including Channel (channel) and Band (range).

Method 4: Analysis via router settings

The most reliable way is to look at your router's control panel. The instructions are universal for most models (TP-Link, ASUS, Keenetic, MikroTik and others):

1. Connect to the router via cable or Wi-Fi.
2. Open your browser and enter the router's IP address (usually 192.168.0.1, 192.168.1.1 or 192.168.8.1).
3. Enter your login and password (by default it is often admin/admin or indicated on the router sticker).
4. Go to the section Wireless network (or Wi-Fi, Wireless).

Further depends on the model:

• 🔹 On TP-Link: chapter Wireless → Wireless Settings → field Band.
• 🔹 On ASUS: Wireless Network → General → Range.
• 🔹 On Keenetic: Wi-Fi network → Access point → Frequency range.

⚠️ Attention: If the router settings indicate Auto or 2.4G + 5G, this means that the network is operating in both ranges simultaneously (but the devices connect to one of them). To find out which one, use methods 1–3.

Method 5: Using third-party programs (for PC)

If standard Windows tools do not show the frequency, use specialized utilities:

1. InSSIDer (free version)

Download InSSIDer from the official website and:

1. Run the program (administrator rights required).
2. In the list of networks, find yours in the column Band the range will be specified.
3. Additionally, you can see Channel (channel) and Width (channel width), which will help optimize the router settings.

2. Acrylic Wi-Fi (paid, but with a trial period)

A more advanced analysis tool:

• 🔹 Shows signal strength in dBm.
• 🔹 Determines Wi-Fi standard (802.11n/ac/ax).
• 🔹 Builds channel load graphs.

🔹 For Linux the following command in the terminal will work:

iwlist wlan0 frequency

(Where wlan0 — the name of your Wi-Fi adapter).

Common problems and solutions

If you've identified the frequency but are still experiencing issues, here are some common scenarios and how to resolve them:

⚠️ Attention: If your router supports Wi-Fi 6E, he can use the range 6 GHzIn this case, a third option will appear in the settings - 6 GHzHowever, such networks are currently only supported by new devices (for example, iPhone 15 or Samsung Galaxy S23).

How to enable 6 GHz support?

To use the 6 GHz band you need:

1. A router with Wi-Fi 6E (for example, ASUS RT-AX89X or TP-Link Archer AXE75).

2. A device that supports 6 GHz (a list of compatible models is available on the Wi-Fi Alliance website).

3. Updated router software (in some countries, 6 GHz requires certification).

FAQ: Frequently Asked Questions about Wi-Fi Frequencies

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

Yes, if the router supports it Dual-BandIn this case, it broadcasts two separate networks (for example, MyWiFi_2G And MyWiFi_5G). You can connect devices to the desired range manually or enable Band Steering for automatic distribution.

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

Preferred for gaming 5 GHz, as it provides lower latency (ping) and more stable speed. However, if your PC or console is far from the router and the 5 GHz signal is weak, it's better to use 2.4 GHz with manual selection of the least loaded channel (1, 6 or 11).

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

Possible reasons:

• 🔹 The device is old and only supports 2.4 GHz (check model specifications).
• 🔹 The 5 GHz band is disabled in the router settings (enable it in the control panel).
• 🔹 In some countries (for example, Israel), the 5 GHz band is limited, requiring you to change the region in your router settings.

How to change the Wi-Fi frequency on a router?

To switch between 2.4 and 5 GHz:

1. Go to your router settings (usually at 192.168.0.1).
2. Find the section Wireless network or Wi-Fi.
3. Select the desired range in the field Band or Frequency.
4. Save the settings and reconnect the devices.

⚠️ After changing the frequency, some devices may lose connection and will need to reconnect.

Does Wi-Fi frequency affect smartphone battery life?

Yes, but indirectly. Range 5 GHz It consumes slightly more power because the Wi-Fi module has to actively "catch" the signal (due to the shorter range). However, the difference usually does not exceed 5–10% of the total battery consumption. It has a much greater impact on battery life. screen brightness or background applications.
