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 if your device doesn't support 5 GHz, has a weak signal, or you want to maximize speed. For example, iPhone 4S and older laptops only see 2.4 GHz, while modern flagships can automatically switch between ranges—but not always optimally.
The difference between frequencies is not only in speed. 2.4 GHz It penetrates walls better and works over a longer distance, but is susceptible to interference from microwaves, Bluetooth devices, and neighboring routers. 5 GHz It's faster and more stable, but the signal weakens after 2-3 rooms. So how do you know which band you're connected to right now? We've compiled all the working methods for Windows, MacOS, Android, iOS and even through the router settings.
Important: Some devices (eg. Xiaomi Mi Band or smart light bulbs Yeelight) only work on a 2.4 GHz network. If they don't connect, the first check is your Wi-Fi frequency.
1. How to find the Wi-Fi frequency on Windows 10/11
In operating systems Windows 10 And Windows 11 There are built-in tools that show connection frequency. The fastest way is through Task Manager:
- Click
Ctrl + Shift + Escto open Task Manager. - Go to the tab Performance.
- In the left menu, select Wi-Fi (or Wireless network).
- In the right part of the window, find the line Network adapter — the frequency will be indicated there (
2.4 GHzor5 GHz).
If Task Manager does not show the frequency, use Command line:
netsh wlan show interfacesFind the line in the results Radio type (Radio Type) - it will be indicated there 802.11n (usually 2.4 GHz) or 802.11ac/ax (5 GHz).
⚠️ Note: On some laptops with adapters Intel or Qualcomm may appear in Task Manager incorrect frequencyIf the driver is out of date, update it via Device Manager → Network Adapters.
2. Checking Wi-Fi Frequency on MacOS
On MacBook or iMac The easiest way to determine the connection frequency is through wireless network monitor:
- Hold down the key
Option (Alt)and click on the Wi-Fi icon in the top bar. - In the drop-down menu, find the line Channel (Channel).
- If the channel number is from
1to14- This 2.4 GHz. Channels36–165relate to 5 GHz.
For more detailed information:
- Open Terminal (
Applications → Utilities → Terminal). - Enter the command:
airport -s - In the list of networks, find yours and look at the column
CHANNEL.
On the new ones Mac with chips Apple Silicon (M1/M2) team airport may not work. In this case, use third-party utilities like WiFi Explorer (free version available in App Store).
3. Determining the frequency on an Android smartphone
On Android There's no universal solution—it all depends on the OS version and manufacturer. Here are some working methods:
- 📱 Via Wi-Fi settings (for Samsung, Xiaomi, Google Pixel):
Go to
Settings → Wi-Fi, tap on your network. In some firmware (for example, One UI from Samsung) there will be a line Frequency or Standard (802.11ac= 5 GHz). - 🔍 Application WiFi Analyzer:
Download from Google Play (For example, WiFi Analyzer from farproc). Open the tab List of access points — the frequency will be indicated next to the network name.
- 📊 Engineering menu (for advanced users):
Enter in the phone dialer
##4636##, select Wi-Fi Information. In the line Frequency the value in MHz will be indicated (for example,2412= 2.4 GHz,5180= 5 GHz).
⚠️ Note: On smartphones Huawei And Honor with firmware EMUI The engineering menu may be blocked. Use applications from AppGallery (For example, WiFi Master Key).
Why doesn't Android have a built-in frequency display?
Manufacturers often hide technical details to simplify the interface. Furthermore, modern smartphones automatically switch between 2.4 and 5 GHz (technology Band Steering), so the frequency display can be misleading.
4. Check on iPhone and iPad
On devices Apple With iOS There's no built-in way to see your Wi-Fi frequency. But there are workarounds:
- 📱 Application AirPort Utility:
1. Download from App Store (for free).
2. Open
Settings → Wi-Fi, tap on the icon «i» near your network.3. A line will appear at the bottom of the screen Channel - determine the frequency using its number (see table below).
- 🖥️ Via Mac (if available):
Connect iPhone To Mac via USB, open Console (
Applications → Utilities → Console) and enter it into the searchawdlThe logs may contain frequency information.
| Channel number | Frequency | Note |
|---|---|---|
| 1–14 | 2.4 GHz | Channel 14 is rarely used (banned in some countries) |
| 36–48 | 5 GHz | Lower 5 GHz band (better through walls) |
| 149–165 | 5 GHz | High range (maximum speed, but weak signal) |
On iPhone 14 Pro and later with the A16 Bionic chip, the frequency can automatically switch between bands without being displayed in settings. If knowing the current frequency is critical to you (for example, to set up a smart home), use a separate router with separate SSIDs for 2.4 and 5 GHz.
5. Viewing the frequency through the router settings
If you have access to your router's admin panel, this is the most reliable method. Instructions:
- Open your browser and enter the router's IP address (usually
192.168.0.1or192.168.1.1). - Enter your login and password (by default it is often
admin/adminor indicated on the device sticker). - Go to the section Wireless network (Wireless).
- Find the settings for 2.4 GHz And 5 GHz — there will be separate SSIDs or a common one with an indication of the range.
Examples for popular models:
- 📡 TP-Link:
Advanced → Wireless → Wireless Settings. - 📡 ASUS:
Wireless → General(switch Band). - 📡 Keenetic:
Wi-Fi → Hotspot(tabs 2.4 GHz And 5 GHz).
⚠️ Attention: If the router is in the Smart Connect (combination of 2.4 and 5 GHz under one name), the current connection frequency of the device can only be determined through its own settings (see sections above).
Separate SSIDs for 2.4 and 5 GHz (e.g. MyWiFi_2G And MyWiFi_5G)
Disable Band Steering (Smart Connect)
Set fixed channels (not Auto)
Check the transmit power (for 5 GHz, 70–80% is recommended)-->
6. Comparing speed and coverage: which one to choose?
Knowing your frequency can help you optimize your connection. Here are the key differences:
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Maximum speed | Up to 300 Mbps (802.11n) |
Up to 1300 Mbps (802.11ac) or 2400 Mbps (802.11ax) |
| Range of action | Up to 50 meters indoors | Up to 20 meters (depending heavily on obstacles) |
| Noise immunity | Low (microwaves and Bluetooth interfere) | High (fewer devices operate at 5 GHz) |
| Device support | All devices (even old ones) | Devices not older than 2012–2015 |
Recommendations for selection:
- 📱 For smart home (sensors, cameras) - only 2.4 GHz (most devices do not support 5GHz).
- 🎮 For online games or 4K streaming — 5 GHz (less delays).
- 🏠 For big house - use both ranges with different SSIDs and connect devices selectively.
7. Common problems and solutions
Sometimes a device fails to connect to 5 GHz or constantly jumps between frequencies. Let's look at typical cases:
- 🔄 Automatic switching (Band Steering):
If the router combines 2.4 and 5 GHz under one name, some devices (for example, Sony PS4 or Nintendo Switch) may get stuck on 2.4 GHz. Solution: Disable it. Smart Connect in the router settings and separate the networks.
- 🚫 5 GHz is not visible on the device:
Check if your device supports 5GHz (eg. iPhone 4S or Samsung Galaxy S2 — no). Also, in some countries (for example, in Russia until 2022), channels 149–165 were blocked—update your router firmware.
- 📶 Weak 5GHz signal:
Try changing the channel to a less busy one (use WiFi Analyzer for analysis). Channels 36–48 are usually more stable than 149–165.
If after splitting the SSID the device still connects to 2.4 GHz, try:
- “Forget” the network in the device settings and connect again.
- Disable it in the router 802.11b/g (leave only 802.11n for 2.4 GHz) - this will force modern devices to prefer 5 GHz.
FAQ: Answers to Frequently Asked Questions
Is it possible to force a device to always use 5GHz?
Yes, if you disable it in the router Smart Connect and create separate networks for 2.4 and 5 GHz. Then manually connect the device to the 5 GHz network. Android You can also secure the connection through the engineering menu (##4636## → Wi-Fi → Wi-Fi frequency band).
Why is the speed on 5 GHz slower than on 2.4 GHz?
This may be due to:
- Weak signal (5 GHz is worse at passing through walls).
- Congested channel (use WiFi Analyzer, to change the channel).
- Outdated Wi-Fi adapter driver (update via
device Manageron Windows orSoftware Updateon Mac).
How do I know which Wi-Fi standard (802.11ac/ax) I'm using?
On Windows enter in the command line:
netsh wlan show interfacesFind the line Radio type (Radio Type). On Mac use WiFi Explorer (shows supported standards). Android - application WiFi Analyzer (tab Details).
Can one device use 2.4 and 5 GHz at the same time?
No, one device can only connect to one band at a time. However, some routers (e.g., ASUS RT-AX88U) support 160 MHz channels at 5 GHz, which doubles the throughput by combining two channels.
How to check which devices are connected to 2.4 GHz and which to 5 GHz?
Log into your router's admin panel (usually 192.168.0.1) and find the section Connected devices (Connected Devices or DHCP Clients). In modern routers (for example, Keenetic or TP-Link Archer) The frequency is indicated next to each device.
