How to find out whether your Wi-Fi is on 2.4 GHz, 5 GHz, or 6 GHz

You're connected to Wi-Fi but don't know if you're using 2.4 GHz or 5 GHzThis information is critical for connection stability: the range affects internet speed, coverage distance, and even device compatibility. For example, smart light bulbs often only work on 2.4 GHz, and modern smartphones support Wi-Fi 6E with a range 6 GHz.

In this article you will find 7 Proven Ways to Determine Wi-Fi Range — from viewing router settings to analyzing networks on your phone or computer. We'll also compare the pros and cons of each band so you can choose the optimal one for your needs. No need to be a tech expert: all methods are thoroughly illustrated and adapted for beginners.

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

Range 2.4 GHz And 5 GHz (and now 6 GHz) are not just numbers. They determine:

• 📶 Signal range: 2.4 GHz is better at passing through walls, but is susceptible to interference from microwaves and neighboring networks.
• ⚡ Data transfer rate5 GHz is faster, but has less coverage. 6 GHz is even faster, but requires compatible devices.
• 🔄 Channel congestion: In apartment buildings, 2.4 GHz is often overloaded, while 5 GHz and 6 GHz are freer.
• 🤖 Compatibility with gadgets: Many IoT devices (cameras, sensors) only operate at 2.4 GHz.

For example, if your Wi-Fi My phone keeps disconnecting in the kitchen. It might not be the router, but the wrong band. Or maybe you bought a new one. iPhone 15, which supports Wi-Fi 6E, but you can't connect to the 6GHz network because the router is not configured.

⚠️ Note: If your router is older than 2018, it most likely does not support 5 GHz, and 6 GHz only appeared in models after 2020 (for example, ASUS RT-AX86U or TP-Link Archer AX6000).

Method 1: View the network name (SSID)

The fastest method is to check your Wi-Fi network name (SSID)Many routers add suffixes to their names by default:

• 📡 _2G, _2.4G, _24G — 2.4 GHz network.
• 🚀 _5G, _5GHz, _PLUS - 5 GHz network.
• ⚡ _6G, _6GHz — 6 GHz network (rare, only in new routers).

Examples:

• Keenetic-123_2G → 2.4 GHz
• TP-Link_AX5400_5G → 5 GHz
• ASUS_RT_6G → 6 GHz

If there are no suffixes, proceed to the next method. Some manufacturers (for example, Xiaomi or Huawei) combine networks under one name - then the range is selected automatically.

Method 2: Check your router settings

The exact method is to go to the router control panel. The instructions are universal for most models (TP-Link, ASUS, Keenetic, Zyxel and others):

1. Open your browser and type in the address bar 192.168.1.1 or 192.168.0.1 (less often) 10.0.0.1).
2. Enter your login and password (usually admin/admin, if you haven't changed it).
3. Go to the section Wireless network (or Wi-Fi, Wireless).

Further depends on the model:

• 🔧 U TP-Link: tabs 2.4GHz And 5GHz on the menu Wireless Settings.
• 🖥️ U ASUS: chapter Wireless network → drop-down list Frequency range.
• 🌐 U Keenetic: Wi-Fi network → Access point → Range.

If there is an option in the settings Smart Connect or Band Steering, the router automatically assigns devices to ranges. In this case, the current range can only be determined on the client device (see methods 3–6).

Find out the router's IP address (usually on a sticker) | Connect to its network | Enter your login/password (admin by default) | Find the Wireless or Wi-Fi section -->

Method 3: Determine the range on Windows 10/11

On a computer or laptop with Windows the range can be found through Task Manager or Command line.

Method 1: Task Manager

1. Click Ctrl + Shift + Escto open the Manager.
2. Go to the tab Performance → Wi-Fi.
3. It will be indicated in the upper right corner Connection And Standard (For example, 802.11ac).

Method 2: Command Line

netsh wlan show interfaces

Find the line in the results Radio type (Radio Type). For example:

• 802.11n — it can be both 2.4 and 5 GHz (additional verification is needed).
• 802.11ac - exactly 5 GHz.

⚠️ Attention: If the results indicate 802.11n, this doesn't guarantee 5 GHz—this standard works in both bands. For accuracy, use method 4 (Wi-Fi analyzer).

Method 4: Use a Wi-Fi analyzer on Android or iOS

Mobile apps show not only the range, but also channel load, signal strength, and even optimization recommendations.

For Android:

• 📱 WiFi Analyzer (from farproc) - free, shows ranges and a load chart.
• 📊 NetSpot - detailed coverage map and channel analysis.

For iPhone/iPad:

• 🍎 AirPort Utility (built into iOS, needs to be enabled in Settings → AirPort Utility).
• 📉 WiFi SweetSpots — visualizes signal strengths by range.

How to use WiFi Analyzer:

1. Open the app and wait for the network scan.
2. Click on the name of your network.
3. There will be a line in the details window Frequency (For example, 2412 MHz - this is 2.4 GHz, 5180 MHz — 5 GHz).

Method 5: Check on MacOS

On MacBook or iMac The range can be found through the utility Wireless diagnostics:

1. Hold Option (⌥) and click on the Wi-Fi icon in the menu bar.
2. Select Open wireless diagnostics.
3. In the diagnostics window, click Window → Scan (or Window → Scan).
4. In the table, find your network and look at the column Channel:

• 📌 Channels 1–14 → 2.4 GHz.
• 📌 Channels 36–165 → 5 GHz.
• 📌 Channels 1–233 (in Wi-Fi 6E) → 6 GHz.

Also in MacOS can be used Terminal:

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

In the results column CHANNEL will show the channel number by which the range is determined.

Method 6: Watching on a Smart TV or set-top box

Modern Smart TV (Samsung, LG, Sony) and prefixes (Apple TV, NVIDIA Shield, Xiaomi Mi Box) also display network information.

On Android TV (Xiaomi, NVIDIA, Philips):

1. Go to Settings → Network & Internet → Wi-Fi.
2. Click on the connected network (do not disconnect!).
3. Scroll down to the section Network information or Additionally.
4. Find the line Frequency or Standard (For example, 5 GHz, 802.11ac).

On Samsung Tizen:

1. Click Menu on the remote control → Settings → General → Net.
2. Select Network status → Wi-Fi Information.
3. In the section Security type or Channel the frequency will be indicated.

⚠️ Warning: On some LG TV With webOS Band information is hidden. In this case, use method 4 (Wi-Fi analyzer on your smartphone).

Method 7: Hardware Test (for advanced users)

If you have physical access to the router, you can determine the range by its technical specifications:

• 🔍 Check the sticker on the back of your router. If the standards are listed 802.11ac or 802.11ax, the device supports 5 GHz (and possibly 6 GHz).
• 📋 Find your router model online (for example, TP-Link Archer C6) and check the specifications on the official website.
• 🔌 If the router has several antennas with markings 2.4G And 5G, the ranges are separated by hardware.

For accurate diagnosis you can use specialized software:

• 🖥️ Wireshark (for PC) - analyzes packets and shows the frequency.
• 📡 inSSIDer (paid, but with a trial version) is a professional tool for monitoring Wi-Fi.

How to find out the range using Wireshark?

1. Download and install Wireshark from the official website.

2. Select the Wi-Fi network interface and start packet capture.

3. In the filter, enter wlan.fc.type_subtype == 8 (these are Beacon frames).

4. In the results, find your network and look at the field DS Parameter Set - it contains the channel number (for example, Channel: 6 → 2.4 GHz, Channel: 44 → 5 GHz).

Range comparison: which one to choose?

Now that you know how to determine a range, all that's left is to choose the optimal one. Here's a quick comparison:

When to choose 2.4 GHz:

• 🏠 A large apartment or house with thick walls.
• 💡 Connecting smart devices (lamps, sensors, cameras).
• 📱 Old smartphones or laptops (before 2015).

When to choose 5 GHz:

• 🛡️ Minimal interference (ideal for offices).
• 💻 Supported devices Wi-Fi 6E (iPhone 15, Samsung Galaxy S23, MacBook Pro M2).

Frequently Asked Questions (FAQ)

My router isn't showing the range in the settings. What should I do?

If the range is not explicitly specified in the router's web interface, check:

1. The router model on the official website may only work at 2.4 GHz (relevant for budget models before 2018).
2. Network name (SSID): if it is the same, but there is an option in the settings Smart Connect, the router distributes devices itself.
3. Use a Wi-Fi analyzer on your smartphone (see Method 4).

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

Yes, almost all modern routers (starting from 802.11n) support simultaneous work in both ranges. To do this:

1. In the router settings, enable both networks (usually the options Enable 2.4GHz And Enable 5GHz).
2. Set different names (SSID) for each band, for example MyWiFi_2G And MyWiFi_5G.
3. Connect devices to the desired network manually.

Exception: Very old routers (pre-2012) or entry-level models may only operate on one band.

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

Possible reasons:

• 📵 The device does not support 5 GHz (check specifications).
• 🔧 The 5 GHz band is disabled in the router settings.
• 📡 5 GHz network is hidden (enable this option) Broadcast SSID in the settings).
• 🛡️ The device is in power saving mode, which disables the 5 GHz adapter.

Solution: Update your router firmware, check your channel settings (some countries limit 5 GHz channels), or reset the network on your device.

Which 5GHz channel should I choose for maximum speed?

In the 5 GHz range, channels are divided into groups:

• 36–48 - lower range, less interference, but may interfere with radars (DFS).
• 149–165 - the upper range is usually freer, but not all devices support it.

Recommendations:

1. Use a Wi-Fi analyzer (eg. WiFi Analyzer) to see the channel load.
2. Select channels marked DFS only if your router and devices support them (there may be automatic switching when radars are detected).
3. For stability, choose channels 36, 40, 44, 48 or 149, 153, 157, 161.

Will Wi-Fi 6E (6GHz) work with older devices?

No, Wi-Fi 6E (6 GHz) requires support on both ends:

• 🔄 The router must support Wi-Fi 6E (For example, ASUS RT-AX86U, Netgear Nighthawk RAXE500).
• 📱 The device must have a 6 GHz adapter (e.g. iPhone 15, Samsung Galaxy S22+, MacBook Pro M1/M2).

If at least one device doesn't support 6 GHz, the connection will fall back to 2.4 or 5 GHz. However, the router itself can broadcast all three bands simultaneously.
