How to Determine Wi-Fi Frequency Range: 2.4 GHz vs. 5 GHz? 7 Proven Methods

Have you ever noticed that your Wi-Fi is sometimes slow, sometimes barely moving, even though the signal indicator shows full bars? The reason may be incorrectly selected frequency range — 2.4 GHz or 5 GHz. These two standards differ radically in speed, range, and resistance to interference, but not all users know how to check which band their device is currently using.

In this article we will look at all possible ways to determine the Wi-Fi range — from built-in operating system tools to specialized applications and router settings analysis. You'll learn how to distinguish 2.4 GHz from 5 GHz networks. Windows 10/11, macOS, Android And iOS, and also learn to analyze your environment to choose the optimal channel. Plus - A unique Wi-Fi 6E (6 GHz) device compatibility chart that you won't find in standard instructions..

1. Why is it important to know your Wi-Fi range?

At first glance, the difference between 2.4 GHz and 5 GHz seems to be purely a matter of speed: the former is slower but has a longer range, while the latter is faster but has poorer wall penetration. However, in practice, the choice of band affects:

• 🔌 Connection stability: 2.4 GHz is overloaded with household appliances (microwaves, wireless mice), and 5 GHz suffers from obstacles.
• 🎮 Latency (ping): For online gaming, 5 GHz is critical, but only if the router is nearby.
• 📱 Device compatibility: Old gadgets (eg. iPhone 4S or Samsung Galaxy S3) do not support 5 GHz.
• 🔄 Automatic roaming: Some mesh systems (eg. Google Nest Wi-Fi) switch between ranges automatically.

Moreover, in 2026 a third player appeared - Wi-Fi 6E (6 GHz), which is currently only supported by flagship devices. If your router and smartphone are compatible, you can get interference-free channels, but first, you need to make sure the network actually operates in that range.

⚠️ Note: In some countries (such as Russia), the 6 GHz band is not yet approved for civilian use. Before purchasing Wi-Fi 6E equipment, please check the current regulations. official sources.

2. How to determine the Wi-Fi range on Windows 10 and 11

Windows has hidden tools that show the range of a connected network, but they're buried deep within system utilities. Here are two reliable methods:

Method 1: Via "Network Information"

1. Right-click on the Wi-Fi icon in the tray and select Open Network & Internet Settings.

2. Scroll to the block Properties and find the line Protocol. It will be indicated there 802.11ac (5 GHz) or 802.11n (2.4 GHz or 5 GHz).

❗ But there's a catch: standard 802.11n Works in both ranges! To find out the exact frequency, you need the second method.

Method 2: Via Command Line (Exact Method)

Open Command line (Win + R → enter cmd) and run:

netsh wlan show interfaces

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

• 📡 802.11n — it can be both 2.4 GHz and 5 GHz (additional verification is needed).
• 🚀 802.11ac or 802.11ax — always 5 GHz.
• 🐢 802.11g or 802.11b - only 2.4 GHz.

If you have 802.11n, please specify the range through device Manager:

1. Click Win + X → device Manager.
2. Expand Network adapters, find your Wi-Fi module (for example, Intel Wi-Fi 6 AX200).
3. Right click → Properties → tab Additionally.
4. Look for the parameter Preferred Band or Wireless Mode — the priority range will be indicated there.

3. Range detection on macOS (including Ventura and Sonoma)

On a Mac, the process is simpler than on Windows, but it does require holding down the Magic key. Follow these steps:

1. Hold down the key Option (⌥) and click on the Wi-Fi icon in the menu bar.

2. A column will appear in the drop-down list Channel (Channel) Channel numbers reveal the range:

⚠️ Attention for M1/M2 MacBook ownersIf the list shows channels higher than 165 (for example, 184), your Mac is connected to the network. Wi-Fi 6E (6 GHz), but only if the router supports this standard (for example, ASUS RT-AX89X or Netgear Nighthawk RAXE500).

For more detailed information, use the built-in utility. Wireless Diagnostics:

1. Hold Option (⌥) and click on the Wi-Fi icon → Open Wi-Fi diagnostics.
2. In the menu, select Window → Utilities → Wi-Fi Scan.
3. Click Scan Now and find the column Band.

4. Checking the range on Android (all versions)

There's no universal method on Android—it all depends on the manufacturer and firmware version. However, there are some general approaches:

Method 1: Via Wi-Fi settings (for most smartphones)

1. Open Settings → Wi-Fi.

2. Tap on the name of your network (not on the switch!).

3. Look for lines like:

• 📶 Frequency or Frequency (For example, 2.4 GHz or 5 GHz).
• 🔗 Standard (802.11ac = 5 GHz, 802.11n = needs to be clarified).
• 📡 Channel (see channel table above).

🔴 Problem: On many smartphones (eg. Xiaomi or Realme) this information is hidden. Then it will help Method 2.

Method 2: Wi-Fi Analysis Apps

Install one of these apps (free versions are sufficient):

• 📊 Wi-Fi Analyzer (from farproc) - shows the range and load of channels.
• 🔍 NetSpot — detailed information about the network, including the standard (a/b/g/n/ac/ax).
• 📶 WiFi SweetSpots - visualizes coverage and ranges.

Example of a report in Wi-Fi Analyzer:

If in the column Band indicated 5 GHz, and in Standard — 802.11ac, your device is connected to 5 GHz. If 2.4 GHz And 802.11n, then it is 2.4 GHz.

⚠️ Attention: On smartphones with MediaTek-chips (many models Redmi, POCO) applications may display incorrect data. In this case, check the range through the router (see Section 6).

5. How to find the Wi-Fi range on iPhone and iPad

Apple traditionally restricts users' access to technical information, but there are workarounds.

Method 1: Via Airport Utility app (official method)

1. Install the app from the App Store Airport Utility (even if you don't have an Apple router).

2. Open Settings → Wi-Fi and tap on the "i" icon next to your network.

3. A line will appear at the bottom of the screen Router - tap on it.

4. In the section Wireless will be indicated Radio Mode (For example, 802.11ac (5 GHz)).

Method 2: Through the hidden field test menu (for advanced users)

This method works on all iPhones, but requires entering a secret code:

1. Open the app Telephone and dial 3001#12345#, then click Call.
2. A menu will open Field TestGo to . Wi-Fi.
3. In the block Wi-Fi Info find Channel And Band.

🔹 Important: On iPhone 12 and later (with support Wi-Fi 6E) may be displayed in this menu 6 GHz, but only if the router and network support it.

What to do if iPhone doesn't see 5 GHz?

If your iPhone (for example, iPhone 6 If your router (or older) isn't seeing 5 GHz networks, the problem may be in your router settings. Try:

1. Enable compatibility mode on your router 802.11a/n/ac (and not only 802.11ac).

2. Make sure the channel width is not set to 160 MHz (some older iPhones do not support it).

3. Check if the 5 GHz network is hidden under another SSID (for example, MyWiFi_5G).

6. Checking the range through the router settings

If the previous methods didn't work or you want to be 100% sure, check your router's web interface. 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 login/password (by default it is often admin/admin).
4. Go to the section Wireless network (or Wireless).

Then everything depends on the firmware:

• 📡 Separate networks for 2.4 and 5 GHz: If you see two SSIDs (eg. MyWiFi And MyWiFi_5G), then the range is determined by the name.
• 🔄 Smart Connect: In some routers (for example, ASUS AiMesh) 2.4 and 5 GHz networks are combined under one name, and the router automatically selects the range. In this case, look Channel (Channel) in the settings.
• 📊 Opening hours: Look for parameters like Wireless Mode or Band. For example, 802.11b/g/n = 2.4 GHz, 802.11a/n/ac/ax = 5 GHz.

Example for a router TP-Link Archer C6:

Wireless Mode: 802.11n/ac → 5 GHz
Channel: 36 (which corresponds to 5 GHz)

⚠️ Attention: On routers with firmware OpenWRT or DD-WRT settings can be found in the section Network → Wireless. Look for the parameter Channel or Frequency.

7. Environmental Analysis: How to Choose the Optimal Range?

Knowing the current range is half the battle. To optimize the network, you need to analyze channel congestion and interference. Here's how to do it:

Step 1: Checking channel load

Use apps to scan the airwaves:

• 🖥 inSSIDer (Windows/macOS) - professional charting tool.
• 📱 WiFi Analyzer (Android) - shows channel load in real time.
• 🍎 NetSpot (macOS/iOS) — creates a heat map of the signal.

🔹 What to look for:

• In the range 2.4 GHz avoid channels 1, 6, 11, if they are overloaded (more than 3-4 networks on one channel).
• In the range 5 GHz choose channels 36–48 or 149–165 (they are less loaded than DFS channels 50–144).

Step 2: Test speed in different ranges

Run speed tests on the same device, connecting to both 2.4 GHz and 5 GHz. Use:

• 🌐 Speedtest.net (browser version).
• 📊 Ookla Speedtest (smartphone application).
• 🖧 Fast.com (from Netflix - checks the speed to their servers).

📌 Typical results:

Step 3: Selection Guidelines

🔹 Choose 2.4 GHz if:

• 📡 You need maximum range (for example, a network at a dacha).
• 📱 You have old devices (manufactured before 2012).
• 🏠 There are many walls and partitions between the router and the device.

🔹 Choose 5 GHz if:

• 🎮 You need low latency (online gaming, video calls).
• 📹 You're watching 4K video or streaming on Twitch.
• 🖥 You have modern devices (released after 2015).

🔹 Choose 6 GHz (Wi-Fi 6E) if:

• 🚀 You have a router and devices that support it Wi-Fi 6E (For example, Samsung Galaxy S22, iPhone 13, ASUS RT-AX86U).
• 🏢 You are in an apartment building with a lot of networks.
• 💻 You need a speed above 1 Gbps.

FAQ: Frequently Asked Questions about Wi-Fi Bands

My router supports both bands, but devices only connect to 2.4 GHz. Why?

This is a typical problem caused by one of the following reasons:

1. The SSID is the same for both bands.: Many devices (especially older ones) default to 2.4 GHz. Solution: separate the networks, for example, MyWiFi_2G And MyWiFi_5G.
2. Weak 5 GHz signal5 GHz has poorer penetration through walls. Solution: Move the device closer to the router or use a repeater.
3. Router settings: In some firmware (for example, Keenetic) 5 GHz is disabled by default to save power. Solution: Enable it manually.

How do I know if my device supports 5GHz or Wi-Fi 6E?

There are three ways:

1. View specifications: Find the device model on the manufacturer's website (for example, gsmarena.com for smartphones). Look for lines like Wi-Fi 5 (802.11ac) (5 GHz) or Wi-Fi 6E (6 GHz).
2. Check in Device Manager (Windows): Open Device Manager → Network Adapters, find your Wi-Fi module and see the supported standards.
3. Connection test: If the device sees and connects to the 5 GHz network (for example, with SSID MyWiFi_5G), which means there is support.

📌 Examples of devices with Wi-Fi 6E (6 GHz):

• Smartphones: iPhone 13/14/15, Samsung Galaxy S21/S22/S23, Google Pixel 6/7.
• Laptops: MacBook Pro (M1 Pro/M2), Dell XPS 13 (2021+), HP Spectre x360 (2022+).
• Routers: ASUS RT-AX86U, Netgear Nighthawk RAXE500, TP-Link Archer AXE75.

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

Yes, almost all modern routers (even budget ones) support it. simultaneous operation in both rangesTo do this:

1. In the router settings, enable both networks (2.4 GHz and 5 GHz).
2. Give them different names (SSIDs), for example, HomeNet And HomeNet_5G.
3. Set up different passwords (optional, but recommended for security).

⚠️ Exception: Some entry-level routers (eg. TP-Link TL-WR840N) support only one range at a time.

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

It's paradoxical, but it happens. Possible reasons:

• 📶 Weak signal5 GHz degrades faster with distance. Solution: Move your device closer to the router.
• 🔄 Congested channelIn apartment buildings, 5 GHz channels (especially 36–48) may be occupied. Solution: Change the channel in your router settings.
• 🖥 Device limitations: Some laptops (e.g. with adapters Intel Wireless-N 7260) support 5 GHz, but only at low speed.
• ⚡ Insufficient router power: Budget routers (for example, Tenda AC10) can choke speeds at 5 GHz. Solution: Update your firmware or buy a more powerful router.

How to force a 5GHz connection on Android if the phone is choosing 2.4GHz?

By default, Android chooses the network with the strongest signal, not the fastest one. To force 5 GHz:

1. Disable 2.4 GHz on your router (temporary solution for tests).
2. Use the app Wi-Fi Priority (requires root rights).
3. Set the priority in developers:

1. Turn on Developer mode (tap 7 times on Build number in the phone settings).
2. Go to Settings → System → Developer Options.
3. Find Aggressive Wi-Fi switching and turn it off.
4. In some firmware (for example, MIUI) there is an option 5 GHz Priority — turn it on.

    

⚠️ Attention: On some devices (eg. Samsung Galaxy With One UI) these settings may be reset after the update.
