How to Check Which Wi-Fi Frequency (2.4GHz or 5GHz) Your Phone Is Connected to – A Complete Guide

Have you ever noticed that your phone's Wi-Fi is sometimes slow, sometimes even though the router is just a meter away? The reason could be network frequency - your smartphone may have automatically connected to a crowded band 2.4 GHz instead of a faster but shorter-range one 5 GHzOr vice versa: you are sitting in the next room, and the phone stubbornly clings to 5 GHz, where the signal barely penetrates the walls.

Knowing your current Wi-Fi frequency helps you not only diagnose speed issues but also configure your router correctly. For example, if you're playing an online game on your phone, it's best to force a connection to 5 GHz for minimal latency. And for a smart home (where stability is more important than speed), it's often optimal. 2.4 GHzIn this article we will analyze All methods for checking Wi-Fi frequency on Android And iPhone — from standard settings to hidden engineering menus.

🔍 Why is this important? Many modern routers broadcast two networks simultaneously (dual-band), but the phone does not always choose the optimal one. For example, iPhone Before iOS 14, it didn't show the frequency in the interface at all, and on Android It all depends on the manufacturer and firmware version.

1. The standard method for Android: where to view the Wi-Fi frequency in the settings

On most smartphones running Android 10 and later The network frequency is displayed directly in the Wi-Fi menu. Here's how to find it:

Open Settings → Wi-Fi (or Network and Internet → Wi-Fi (On some firmware versions). Tap your network name—a window with detailed information will open. Look for lines like:

  • 📡 Frequency (for example, "2.4 GHz" or "5 GHz")
  • 🔗 Speed (at 5 GHz usually higher, for example 866 Mbps versus 150 Mbps 2.4 GHz)
  • 📶 Standard (for example, "802.11ac" is 5 GHz, and "802.11n" can be anything)

⚠️ Attention: On phones Xiaomi, Redmi And POCO With MIUI firmware, the frequency can be hidden behind a button Additionally or Advanced settingsIf you don't see the data, try swiping the network information screen to the left.

On Samsung Galaxy (One UI) the path is: Settings → Connections → Wi-Fi → ⚙️ (gear next to the network) → FrequencyIf the line is missing, your phone does not support displaying this information in the standard interface (proceed to the next methods).

Check your Android version (must be 10+)

2. Hidden engineering menus: how to find out the Wi-Fi frequency on any Android

If the default settings are silent, this will help engineering menu — hidden section with technical information. This method works even on older versions of Android and custom firmware, but requires caution: do not change parameters if you are not sure of their purpose!

Instructions for most phones:

  1. Open the app Telephone (dialer).
  2. Enter the combination: ##4636## (For Mediatek) or *#0011# (For Samsung Exynos/Qualcomm).
  3. Select an item Wi-Fi information or Wi-Fi Information.
  4. Look for the line Frequency - there will be a value in megahertz (for example, 2412 - This 2.4 GHz, 5180 — 5 GHz).

📌 Frequency decoding:

  • 🔢 2412–2484 MHz → range 2.4 GHz
  • 🔢 5170–5825 MHz → range 5 GHz

⚠️ Attention: On some phones (eg. Huawei with processors Kirin) The engineering menu may be blocked. In this case, try alternative combinations: 

##2846579## → ProjectMenu → Background Settings → WLAN
##36446337## → WLAN
What should I do if the engineering menu doesn't open?

If nothing happens after entering the code, it is possible:

1. The manufacturer has disabled access (applicable to some Xiaomi and Huawei models after 2021).

2. You have a lightweight firmware installed (for example, Android Go), where the engineering menu is cut down.

3. Phones with an Apple processor (iPhone) - this method is not suitable for them (see the section on iOS).

3. Wi-Fi Analysis Apps: Accurate Data in 2 Clicks

If you don't want to fiddle with settings, install one of the specialized apps. They will not only show your current frequency but also analyze channel load, signal strength, and even suggest optimal router settings.

📱 Top 3 Android Apps:

  • 🛠️ WiFi Analyzer (from VREM Software) - shows the frequency, channel, signal level and airtime.
  • 📊 NetSpot — creates a heat map of coverage and highlights the networks in color 2.4 GHz And 5 GHz.
  • 🔍 Fing — determines the frequency, MAC address of the router, and even the models of connected devices.

📱 For iPhone:

  • 🌐 AirPort Utility (official from Apple) - after turning on the mode Wi-Fi Scanner shows the frequency in the settings.
  • 📶 WiFi SweetSpots — visualizes coverage and marks networks in different colors depending on the range.

💡 How to use:

  1. Install the app from Google Play or App Store.
  2. Connect to your Wi-Fi network.
  3. Start the scan - the frequency will be displayed in the first lines of the report.

4. How to check Wi-Fi frequency on iPhone (iOS)

Apple traditionally hides technical details from users, so iPhone There's no direct way to see the frequency in the settings. However, there are workarounds:

🔹 Method 1: Using Wi-Fi Diagnostics (works on iOS 14+):

  1. Open Settings → Wi-Fi.
  2. Tap on the symbol ⓘ near your network.
  3. Hold your finger on the field Router address (or IP address) and copy it.
  4. Open your browser and type http://[copied_IP]/airportutility (For example, http://192.168.1.1/airportutility).
  5. If your router supports this feature, you will see a page with details, including the frequency.

🔹 Method 2: Via the app AirPort Utility (for Apple routers):

  1. Download AirPort Utility from App Store.
  2. Launch it, tap on your router.
  3. Go to Wireless → Radio Mode — the range will be indicated there (2.4 GHz or 5 GHz).

⚠️ Attention: On iPhones with iOS 13 or later, some methods may not work due to Apple restrictions. If none of these methods work, try using third-party apps (see the previous section) or check your router settings (see below).

5. Checking via the router's web interface: a universal method

If your phone stubbornly won't show the frequency, check your router settings. This method works regardless of your smartphone model or OS version.

🖥️ How to access router settings:

  1. Find out the IP address of the router (usually 192.168.0.1, 192.168.1.1 or 192.168.8.1). It can be found on a sticker on the device body or in the instructions.
  2. Open a browser on your phone or computer and enter this IP in the address bar.
  3. Enter your login and password (by default it is often admin/admin or admin/password).
  4. Go to the wireless network section (usually Wireless, Wi-Fi or WLAN).

📋 Where to look for frequency:

Router manufacturer Settings section What to look for
TP-Link Wireless → Wireless Settings Field Channel (channel 1-13 - 2.4 GHz, 36–165 — 5 GHz)
ASUS Wireless → General Field Control Channel or Band
Keenetic Wi-Fi network → Main network Field Range (2.4 GHz or 5 GHz)
Xiaomi Wi-Fi → Wi-Fi Settings Field Frequency or Opening hours

⚠️ Attention: If the mode is enabled in the router settings Auto (automatic channel selection), the frequency may change dynamically. In this case, check the current value on your phone or app.

6. How to force a Wi-Fi frequency on your phone

If you find that your phone is connected to a suboptimal frequency, you can change it. Here's how:

📲 On Android:

  • 🔄 Disable automatic selection: In the Wi-Fi settings, find the option Intelligent connection (at Samsung), Smart Wi-Fi (at Xiaomi) or Band Steering and turn it off.
  • 📡 Connect to the desired frequency: If the router broadcasts two separate networks (for example, MyWiFi_2G And MyWiFi_5G), select the desired one manually.
  • 🔧 Use applications: WiFi Manager or WiFi Priority allow you to set the priority of ranges.

🍎 On iPhone:

Apple doesn't allow you to directly select the frequency, but you can bypass the restriction:

  1. Forget the current network: Settings → Wi-Fi → ⓘ → Forget this network.
  2. Disable broadcasting on your router 2.4 GHz (if you want to force a connection to 5 GHz) or vice versa.
  3. Reconnect - iPhone will select the only available band.

💡 Advice for gamers: If you are playing on your phone via Wi-Fi, force it to connect to 5 GHz and in the router settings, assign a channel (for example, 36 or 149) instead of the mode AutoThis will reduce latency (ping) and prevent sudden reconnections.

7. Common problems and their solutions

🔴 Problem 1: The phone does not show the frequency in the settings.

🔹 Solution: Update your phone's firmware or use third-party applications (WiFi Analyzer, Fing).

🔴 Problem 2: The iPhone stubbornly clings to 2.4 GHz, Although 5 GHz free.

🔹 Solution: Disable it on your router 2.4 GHz for 10 minutes or rename the networks (for example, add to the name 5G for the range 5 GHz).

🔴 Problem 3: Speed ​​on 5 GHz lower than 2.4 GHz.

🔹 Solution: Check:

  • 📶 Distance to the router (on 5 GHz the signal passes weaker through walls).
  • 🔄 Channel in the router settings (it may be overloaded with other networks).
  • 🔌 Router power supply (insufficient voltage may limit speed).

⚠️ Attention: If after forced connection to 5 GHz The internet connection disappears when moving around the apartment, please return to 2.4 GHz or customize Roaming Assist (If available on your router). This feature automatically switches devices between bands when the signal deteriorates.

Why might my phone get stuck on 2.4 GHz?

Many phones (especially budget ones) choose by default 2.4 GHz because of:

1. Longer range coverage (important for saving battery power).

2. Better compatibility with older routers.

3. Power saving algorithms that prefer speed stability.

To avoid this, disable the Wi-Fi option in your settings. Adaptive Wi-Fi or Optimize Network (the name depends on the firmware).

FAQ: Answers to frequently asked questions

🔹 Is it possible to find out the Wi-Fi frequency without a phone, only through a computer?
