How to check your Wi-Fi frequency (2.4 or 5 GHz) – all methods for different devices

Are you connected to Wi-Fi, but the speed is still slow? The problem might be router broadcast frequencyModern routers operate on two ranges - 2.4 GHz And 5 GHz, and the choice affects not only the internet speed, but also the stability of the connection. For example, At 5 GHz, the speed can be 2-3 times higher, but the signal penetrates walls worse, while 2.4 GHz is more resistant to interference, but is often overloaded by neighboring networks..

In this article, we'll look at how to accurately determine the frequency your Wi-Fi is operating on—right now, without any special software. These methods are suitable for Windows, MacOS, Android, iOS, as well as for checking router and smart device settings (TVs, set-top boxes). You'll learn why some gadgets don't see the 5 GHz network, how to force switching between bands, and what to do if your router doesn't support 5 GHz (even though it should).

Warning: If your router is older than 2015, it may not support 5 GHz This is normal for budget models. However, if the device is new but doesn't show the 5 GHz network, the problem may be in the settings or drivers.

1. How to find out the Wi-Fi frequency on Windows 10/11 without programs

The fastest way is through Network SettingsIt works on all versions. Windows starting from 10th, does not require administrator rights and takes less than a minute.

Open the menu Start → Settings → Network & Internet → Wi-FiFind the line Equipment properties (it's located under your network name). It will be listed here protocol (For example, Wi-Fi 5 (802.11ac)) And frequency band:

• 📡 2.4 GHz - if specified 802.11b/g/n or simply 2.4 GHz.
• 🚀 5 GHz - if specified 802.11a/ac/ax or 5 GHz.

If there is no frequency information in the properties, try the second method: open task manager (Ctrl+Shift+Esc), go to the tab Performance → Wi-Fi. It will be indicated in the upper right corner. frequency band (For example, Channel 6 (2.4 GHz)).

⚠️ Attention: If the task manager shows 802.11n without specifying the frequency, your device can operate in mixed mode (automatic switching between 2.4 and 5 GHz). To find out the current frequency, use the command line method (section 3).

2. Checking the Wi-Fi frequency on MacOS (MacBook, iMac)

On MacOS It is easier to determine the network frequency than on Windows - just hold down the key Option (⌥) when you click on the Wi-Fi icon in the menu bar.

Step-by-step instructions:

1. Hold down the key Option (⌥) on the keyboard.
2. Click on the Wi-Fi icon in the upper right corner of the screen.
3. A line will appear in the drop-down menu next to the name of your network. Channel (channel) and frequency - for example, Channel 36 (5 GHz).

If there is no frequency information in the menu, open System information:

• 🍎 Click on the Apple logo in the upper left corner → About This Mac → System Report → Network → Wi-Fi.
• 🔍 In the section Interface find the line Supported PHY Modes. If there is one there 802.11a or 802.11ac, does your Mac support 5 GHz.

3. Command Prompt: A Universal Method for Windows

If the GUI does not show the frequency, use command lineThis method works even on older versions. Windows 7/8.

Open Command Prompt (Win + R → cmd → Enter) and enter:

netsh wlan show interfaces

Find the line in the results Channel (channel) and Radio type (radio module type):

For example, if the output states Channel: 6 And Radio type: 802.11n, your device is connected to 2.4 GHz.

What to do if the command line does not show the frequency?

If after entering the command you see an error or the line is missing Channel, try updating your Wi-Fi adapter driver:

1. Open device Manager (Win + X → Device Manager).
2. Find the section Network adapters → select your Wi-Fi module (for example, Intel Wi-Fi 6).
3. Right click → Update driver → Automatic search.

After updating, please check again via command line.

4. How to check Wi-Fi frequency on Android and iOS

Determining the network frequency on smartphones is more difficult—manufacturers often hide this information. But there are workarounds.

📱 Android

Most phones on Android They don't show the frequency in the settings, but you can use the apps:

• 🔍 WiFi Analyzer (free) - shows all networks around, indicating frequency and channel.
• 📊 Network Analyzer - detailed connection information, including Channel Width (channel width) and Frequency.

If you don't want to install apps, try this trick:

1. Open Settings → Wi-Fi.
2. Click on the name of your network → Additionally or Network mode.
3. If there is an option Frequency range or Band, it will be indicated there 2.4 GHz or 5 GHz.

🍎 iPhone (iOS)

On iPhone There is no built-in way to find out the Wi-Fi frequency, but you can use an app AirPort Utility (official from Apple):

Download AirPort Utility from the App Store | Open the app → Tap the Wi-Fi icon in the upper right corner | Select your network → View the line Channel (channels 36–165 = 5 GHz)|-->

If the channel is from 1 to 14, it is 2.4 GHz, if from 36 to 165 - 5 GHz.

⚠️ Attention: Some older models iPhone (to iPhone 5) do not support 5 GHzIf your phone doesn't detect 5 GHz networks, check the model's specifications on the Apple website.

5. Check the Wi-Fi frequency in the router settings

The most reliable way is to log in router web interface and view your wireless network settings. This will not only help you find out your current frequency, but also, if necessary, force switch between 2.4 and 5 GHz.

Instructions:

1. Open your browser and type in the address bar 192.168.0.1 or 192.168.1.1 (the address may differ - look on the router sticker).
2. Enter your login and password (usually by default admin/admin or admin/empty).
3. Go to the section Wireless (Wireless network), Wi-Fi Settings or Dual Band (names depend on the router model).
4. Find the parameter Band, Frequency or Wireless Mode:

If specified in the settings Auto or 2.4G/5G, the router automatically selects the frequency. To force it to turn on 5 GHz, select the appropriate mode (for example, 802.11ac) and save the settings.

⚠️ Attention: After changing the frequency in your router, some devices (such as older smartphones or smart light bulbs) may lose connection. If this happens, reset the settings to Auto or create a separate network for 2.4 GHz.

6. How to find out the Wi-Fi frequency on Smart TVs and set-top boxes

Smart TVs (Samsung, LG, Sony) and prefixes (Xiaomi Mi Box, Apple TV) often connect to Wi-Fi but don't show its frequency. Here's how to check:

📺 Smart TV (Samsung, LG, Sony, Philips)

• 🔧 Go to Settings → Network → Network Status (path may differ).
• 🔍 On Samsung Click on the network name → Additional information → Frequency.
• 📊 On LG open All Settings → Network → Wi-Fi → Advanced.

If there is no frequency information in the TV menu, use router: go to its settings (section 5) and see what frequency your device is connected to in the list of clients (DHCP Clients or Connected Devices).

🎮 Set-top boxes (Xiaomi, Apple TV, Android TV)

• 📦 On Xiaomi Mi Box or Android TV: Settings → Network → Wi-Fi → Advanced → Band.
• 🍎 On Apple TV: hold down the button Menu on the remote control → Settings → Network → Wi-Fi → Current Network (the frequency is not displayed, but you can judge by the speed: if it is more than 300 Mbps, it is most likely 5 GHz).

If your TV or set-top box does not connect to 5 GHz, update the firmware or check the router settings - some models (for example, Xiaomi Mi Router 3) hide the 5 GHz network by default for compatibility.

7. Why is it important to know your Wi-Fi frequency and when to change it?

Three key network parameters depend on the selected frequency:

1. Speed: on 5 GHz The theoretical speed is higher (up to 1–2 Gbps versus 300–600 Mbps on 2.4 GHz), but the actual speed depends on interference and distance.
2. Range: 2.4 GHz It passes through walls better and works at a distance of up to 50 meters, and 5 GHz — up to 20 meters.
3. Workload: on 2.4 GHz There is usually more interference from neighbors, microwaves, and Bluetooth devices.

When to switch:

• 🎮 For gaming and streaming (Twitch, YouTube in 4K) - use 5 GHz (less ping).
• 📱 For older devices (smartphones before 2016, smart bulbs) - only 2.4 GHz.
• 🏠 For a big house - if the router is far away, 2.4 GHz more stable.
• 🖥️ For an office with multiple devices — separate the networks: laptops on 5 GHz, printers/cameras on 2.4 GHz.

If your router supports Wi-Fi 6 (802.11ax), it can automatically optimize the frequency. Otherwise, try manually switching between bands and measuring the speed (for example, through Speedtest).

8. Common problems and solutions

Sometimes devices don't see the 5 GHz network or connect to the wrong band. Let's look at some of the following:

🔄 The device automatically connects to 2.4 GHz instead of 5 GHz

Reason: Many routers use the same network name (SSID) for both bands, and the device selects the more stable one (usually 2.4 GHz). Solution:

• 📛 Divide the networks: in the router settings, create two networks with different names (for example, MyWiFi_2G And MyWiFi_5G).
• 🔄 Disable 2.4 GHz for a while for the device to connect to 5 GHz.
• 🔧 Update your Wi-Fi driver (relevant for laptops on Windows).

📵 The device doesn't see the 5 GHz network

Possible causes and solutions:

📉 The speed on 5 GHz is lower than on 2.4 GHz

This may be due to:

• 📡 Weak signal (router is far away or there are many obstacles).
• 🔄 Congested channel (neighbors are using the same channel).
• 🛠️ Outdated router firmware.

Solution:

1. Change the channel to 5 GHz in the router settings (select 36, 40, 44 or 48 - they intersect the least).
2. Update your router firmware (section Administration → Firmware Upgrade).
3. Check if there is a microwave or other device nearby that is causing interference.

⚠️ Attention: Channel and transmission power settings may vary depending on the regulations in your country. For example, in Russia, channels 36–64 and 100–140 are permitted on the 5 GHz band, while in Europe, channels 36–64 and 149–165 are permitted. Manually selecting an unauthorized channel may result in network instability.

FAQ: Frequently Asked Questions about Wi-Fi Bandwidth

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

Possible reasons:

• Your phone does not support 5GHz (check model specifications).
• The router is in the enabled mode 802.11n only (try switching to 802.11a/n/ac).
• The channel width is set to 80 MHz or 160 MHz - some devices do not support such settings (try 20/40 MHz).

How to force a 5GHz connection on Windows?

If your laptop automatically locks onto 2.4 GHz:

1. Open Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings.
2. Right-click on your Wi-Fi connection → Properties → Configure.
3. Go to the tab Additionally → find the parameter Preferred Band or Wireless Mode.
4. Select 5 GHz only or 802.11a and save.

If there is no such parameter, update your Wi-Fi adapter driver.

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

Yes, most modern routers support it. simultaneous work on both frequencies. To do this:

• Enable the mode in your router settings. Dual Band or 2.4G/5G.
• Create two separate networks with different names (eg. MyWiFi_2G And MyWiFi_5G).
• Connect devices to the desired network manually.

This is useful if you have devices that only operate on 2.4 GHz (such as smart plugs) and can connect the rest to 5 GHz for faster speeds.

Which 5GHz channel should I choose for maximum speed?

On 5 GHz, it's best to choose channels that don't overlap with neighboring networks. Use apps like WiFi Analyzer (Android) or NetSpot (Windows/Mac) to see channel load.

Recommended channels for Russia:

• 36, 40, 44, 48 (less busy).
• 149, 153, 157, 161 (if your router supports DFS).

Avoid channels 50–144 - they may conflict with radars (their use is prohibited in some countries).

Does Wi-Fi frequency affect ping in games?

Yes, but not always as it seems:

• 🎮 5 GHz usually gives lower ping, because there is less interference and higher response speed.
• 🏠 However, if you are far from the router, the 5 GHz signal may be weak, and the ping, on the contrary, will increase due to packet loss.
• 🔄 The best option for gamers: connect to 5 GHz, but stand closer to the router or use Mesh system.

Check ping via ping google.com -t in the command line on both frequencies and compare the results.
