How to check the Wi-Fi frequency on your phone: 2.4 GHz or 5 GHz?

You've connected to your home or office Wi-Fi network, but you don't know if your phone is working on the frequency. 2.4 GHz or 5 GHzThis information is critical if your router supports both bands, but your internet speed is poor. For example, 5 GHz provides higher throughput, but passes through walls worse, whereas 2.4 GHz More stable over longer distances, but susceptible to interference from neighboring networks.

In this article you will find Universal methods for checking Wi-Fi frequency on Android and iOS phones without installing third-party apps, and learn how to use this information to optimize your connection. We'll explore hidden settings, system tools, and alternative methods—from analyzing the network name to using built-in diagnostic functions.

Why is it important to know the Wi-Fi frequency on your phone?

Ranges 2.4 GHz And 5 GHz (and in new routers and 6 GHz) have fundamental differences that directly impact the user experience:

• 📶 2.4 GHz: Greater coverage, but lower speed and higher channel congestion (especially in apartment buildings). Suitable for devices located far from the router or with a weak signal.
• ⚡ 5 GHz: Higher speed and less interference, but the signal fades faster over distance and through obstacles. Ideal for online gaming, 4K streaming, or using cloud services.
• 🆕 6 GHz (Wi-Fi 6E): maximum speed and minimal interference, but only supported by modern devices and routers.

Knowing the current frequency will help:

• 🔧 Configure the router for optimal distribution of devices across ranges (for example, send a smartphone to 5 GHz, and smart light bulbs are on 2.4 GHz).
• 📉 Diagnose the causes of slow internet (if the phone is stuck on an overloaded 2.4 GHz).
• 🛠️ Check if the function is working correctly Band Steering (automatic switching between frequencies) on the router.

⚠️ Attention: If your router does not support 5 GHz, the phone will automatically connect to 2.4 GHz — checking the frequency in this case is pointless. Check the router's specifications in its web interface or documentation.

Method 1: Checking via Wi-Fi settings on Android

On most modern smartphones running Android 10+ (including Samsung, Xiaomi, Google Pixel, OnePlus) You can find the network frequency directly in the connections menu. These instructions are valid for stock Android and shells with minimal modifications:

1. Open Settings → Wi-Fi (or Network and Internet → Wi-Fi).
2. Click on the name of the current network your phone is connected to.
3. Scroll down to the block Frequency, Range or Band — it will be indicated here 2.4 GHz or 5 GHz.

If there is no such item, try an alternative path:

1. Tap and hold the network name in the list of available connections.
2. In the menu that appears, select Change network or Additionally.
3. Look for the line Frequency or Standard (on some devices Samsung).

On Xiaomi (MIUI) and some other shells the path may differ:

Settings → Wi-Fi → [Network name] → "Advanced settings" → "Network frequency"

⚠️ Note: Manufacturers often hide technical details in new firmware versions. If there's no frequency information in the settings, proceed to the next method.

Press and hold the network name and select "Delete" (sometimes reconnecting helps)

Check for system updates in Settings → System → Software Update

Install a Wi-Fi analyzer app (see Method 3)

-->

Method 2: Determining the frequency by network name (SSID)

Many routers create separate network names by default (SSID) for each range. For example:

• MyWiFi_2G or MyWiFi-2.4 — network on 2.4 GHz.
• MyWiFi_5G or MyWiFi-5 — network on 5 GHz.
• MyWiFi_6G — network on 6 GHz (if supported).

Check your network name in the list of available connections. If it contains a number 5 or postfix 5G (not to be confused with 5G mobile communications!), then you are connected to the range 5 GHz. Similarly for 2.4 or 2G.

If the network names are the same, but the router supports both ranges, the function is most likely enabled Band Steering (or Smart Connect on ASUS, One Wi-Fi on TP-Link). In this case:

• 🔄 The router automatically switches devices between frequencies depending on the signal.
• 📱 The phone may "stick" on a less optimal range (for example, remain on 2.4 GHz, even if 5 GHz available).

Yes, and I know what they are called.

Yes, but the network names are the same.

No, only 2.4 GHz

I don't know, I haven't checked-->

Method 3: Wi-Fi Analysis Apps (Android)

If your system settings don't show your frequency, use third-party utilities. They will not only determine the frequency range but also visualize channel load, signal strength, and other parameters. We recommend these proven apps:

• 📊 WiFi Analyzer (from VREM Software) — shows the frequency, channel, signal strength, and load graph. The free version is sufficient for basic diagnostics.
• 🔍 NetSpot — detailed network analysis, including ranges, standards (Wi-Fi 4/5/6) and optimization recommendations.
• 📶 Fing — determines the frequency of the connected network in the section Wi-Fi → Analysis.

Instructions for WiFi Analyzer:

1. Install the app from Google Play and open it.
2. Go to the tab AP List (Access Points).
3. Find your network in the list - in the column Frequency or Band the range will be specified.
4. For a detailed analysis, switch to the tab Channel schedule - networks 2.4 GHz are displayed in the range of channels 1–14, and 5 GHz — 36–165.

Example of display in WiFi Analyzer:

Network name: MyWiFi_5G
BSSID: AA:BB:CC:DD:EE:FF
Channel: 44 (5 GHz)
Standard: 802.11ac (Wi-Fi 5)
Power: -55 dBm

⚠️ Note: Some applications (eg. WiFi Analyzer from other developers) may require location access permissions. This is due to restrictions Android To scan networks, disable geolocation after analysis.

Method 4: Checking on iPhone (iOS)

On iPhone And iPad under control iOS There's no built-in way to find out the frequency of a connected Wi-Fi network through the default settings. However, there are workarounds:

Method 1: Using the Airport Utility app (Apple's official method)

Airport Utility — a utility from Apple for managing routers AirPort, but it can also be used to analyze any networks:

1. Download Airport Utility from App Store (if deleted).
2. Open the app and tap on the icon Wi-Fi Scan in the upper right corner.
3. Click Scan and wait for the scanning to complete.
4. Find your network in the list - in the column Band will be indicated 2.4 GHz or 5 GHz.

Method 2: Through third-party applications

Alternative utilities for iOS with Wi-Fi analysis function:

• 🌐 WiFi SweetSpots - shows frequency, channel and signal strength.
• 📡 Network Analyzer — detailed information about the network, including range and standard (802.11n/ac/ax).

Limitation iOS: because of politics Apple Apps can't directly scan networks in the background. Scans must be initiated manually for analysis.

Why does Apple hide Wi-Fi frequency information?

iOS doesn't have an API for retrieving data about the connected network's frequency for security and interface standardization reasons. Apple believes that users don't need technical details as long as the network is stable. However, this creates challenges when diagnosing connection issues or configuring the router.

Method 5: Via the router's web interface

If your phone doesn't show the frequency and apps aren't helping, check the information directly in your router settings. To do this:

1. Find out Router IP address (usually 192.168.0.1, 192.168.1.1 or indicated on the device sticker).
2. Open a browser on your phone or computer and enter this address in the address bar.
3. Log in (default logins/passwords: admin/admin, admin/blank password or see sticker).
4. Go to the wireless network section (for example, Wireless, Wi-Fi, Wireless mode).
5. Check the band your device is connected to. Some routers have a tab. Connected Devices or DHCP Clients, where you can see the range for each client.

Example for a router TP-Link:

1. Log in 192.168.0.1
2. Go to Wireless → Wireless Statistics
3. Find the phone's MAC address in the table and look at the column Band

If there is no such information in the router interface, try:

• 🔄 Reconnect your phone to the network and monitor the logs in the section System Log or Magazine.
• 📋 Enable network separation by range (disable Smart Connect) and reconnect.

⚠️ Note: Router interfaces vary depending on the model and firmware version. If you can't find the section you need, check the documentation for your model.

Method 6: Via the command line (for advanced users)

On Android with rights root or through ADB (Android Debug Bridge) allows you to find out the network frequency using commands. This method is suitable for tech-savvy users.

Method 1: Via ADB (without root)

Connect your phone to your computer and run the following commands:

adb shell
dumpsys wifi | grep frequency

In the output, look for a line like this frequency=5180 (value in MHz). To convert to GHz:

• 2412–2484 → 2.4 GHz.
• 5170–5825 → 5 GHz.

Method 2: Via terminal (as root)

Install the application Termux and run:

su
cat /proc/net/wireless
iwconfig wlan0

The output will contain the line Frequency:5.18 GHz or similar.

⚠️ Caution: Use ADB or root-access may violate the warranty or the stability of the device. Use these methods only if you are confident in your actions.

Common problems and solutions

When checking your Wi-Fi frequency, you may encounter common issues. Let's look at them and how to solve them:

If the phone stubbornly "sticks" on 2.4 GHz, despite the presence 5 GHz:

• 🔌 Restart your router and phone.
• 📵 Forget the network in your phone settings and reconnect.
• 📡 In your router settings, set different names (SSIDs) for 2.4 and 5 GHz and connect to the desired network manually.

FAQ: Frequently Asked Questions

My phone supports 5GHz, but only connects to 2.4GHz. How can I fix this?

The reasons may be different:

• 📶 Weak signal 5 GHz — bring your phone closer to the router.
• 🔄 Enabled Band Steering - disable it in the router settings.
• 🔒 MAC address restriction - check your router settings for device filtering.

Also try to manually specify the channel for 5 GHz in the router settings (for example, 36, 40 or 44) - some phones do not work well with DFS channels (50-144).

How do I know if my phone supports 5GHz?

Check the model specifications on the manufacturer's website or in the documentation. Most smartphones after 2016 support 5 GHz, but budget models (for example, some Redmi or Samsung Galaxy J-series) may be limited 2.4 GHz.

Alternative method: if in the list of available networks you see networks with the postfix 5G (not to be confused with mobile network!), your phone supports this range.

Is it possible to force a phone to use 5GHz?

Yes, if the router is configured accordingly:

1. Disable it in your router settings. Smart Connect (or similar function).
2. Assign to networks 2.4 GHz And 5 GHz different names (for example, MyWiFi_2 And MyWiFi_5).
3. On your phone, connect to the network with _5 in the title.

On some phones (eg. Samsung) there is an option in the Wi-Fi settings Intelligent Wi-Fi - Disable it to prevent automatic switching.

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

It's paradoxical, but possible reasons:

• 📡 Signal 5 GHz too weak (e.g. -70 dBm or worse) - the phone reduces the speed for stability.
• 🔌 The router is overloaded - check how many devices are connected to it 5 GHz.
• 🔄 A narrow channel is being used (20 MHz instead of 40/80 MHz) - change the channel settings in the router.
• 🛠️ The router is in compatibility mode (for example, 802.11n instead of 802.11ac) - update the firmware.

Check the speed on Speedtest, standing next to the router. If on 5 GHz the speed is higher, the problem is in the coverage.

How to check the Wi-Fi frequency on a phone without access to the router?

If you are connected to someone else's network (for example, in a cafe or hotel) and don't have access to your router settings, use:

• 📱 Wi-Fi analysis apps (see Method 3).
• 🔍 Look at the network name - if it contains 5G or 5GHz, you are on a high frequency.
• 📊 On Android With root-use the command for access iwconfig wlan0 (cm. Method 6).

Please note: it is often disabled on public networks. 5 GHz for compatibility with older devices.
