How to check your Wi-Fi network frequency via your phone: 2.4 or 5 GHz

You've connected to your home or office Wi-Fi network, but you don't know what frequency the access point is operating on. 2.4 GHz or 5 GHzThis information is critical for diagnosing speed issues, selecting the optimal channel, or configuring dual-band routers. Unfortunately, most smartphones don't display the network frequency in their default settings, but there are several ways to determine it—both with built-in tools and third-party apps.

In this article you will find step by step instructions for Android And iOS, including hidden developer menus, MAC address analysis, and specialized utilities. We'll also discuss why it's important to know your Wi-Fi frequency, how it affects connection speed and stability, and what to do if your phone can't detect the 5 GHz network. All methods have been tested on current operating system versions (as of 2026) and don't require root access or jailbreaking.

Why is it important to know your Wi-Fi network frequency?

Ranges 2.4 GHz And 5 GHz They differ fundamentally in their characteristics, and choosing the wrong frequency can lead to problems:

• 📶 2.4 GHz: greater coverage area, but high channel congestion (especially in apartment buildings). Speed ​​is limited to ~150–300 Mbps, and there's strong interference from microwaves and Bluetooth devices.
• 🚀 5 GHz: shorter range, but higher speed (up to 1–2 Gbps) and less interference. The signal penetrates walls less effectively and requires closer proximity to the router.
• ⚡ Dual-band routers: often two networks with the same name are created (SSID), and the phone may connect to a less optimal frequency automatically.

Knowing the current frequency will help:

• 🔧 Set up Band Steering on the router (automatic range selection).
• 📊 Diagnose the causes of slow or disconnected connections.
• 🔄 Force switch to another band if the network supports it.

For example, if your iPhone or Samsung Galaxy It constantly locks onto 2.4 GHz, even though there's a free 5 GHz network nearby. You can manually set the priority band in your router or phone settings.

Method 1: Via Android settings (without apps)

On most smartphones Android The Wi-Fi frequency is not displayed in the basic interface, but it can be found out through hidden network information menuThe instructions are suitable for devices on a clean Android 10–14 (including Pixel, Samsung One UI, Xiaomi MIUI etc.), but may differ on custom firmware.

1. Open Settings → Wi-Fi.
2. Find your network in the list and tap on its name (SSID).
3. In the window that opens, click on Additionally, Network information or the ⚙️ (gear) icon.
4. Scroll down to the block Technical information or Connection information.
5. Find the line Frequency, Band or Range. It will be indicated there 2.4 GHz or 5 GHz.

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

1. Connect to Wi-Fi.
2. Open Settings → About phone → Software version.
3. Tap the item 7 times Build numberto activate developer mode.
4. Return to Settings → System → Developer Mode.
5. Find the option Debugging over Wi-Fi or Wi-Fi Information — the frequency may be displayed there.

⚠️ Attention: On some firmware (for example, ColorOS from Oppo/Realme) The developer menu may not contain frequency data. In this case, use third-party apps (see Method 3).

Update your phone's firmware to the latest version

Try connecting to a different Wi-Fi network

Use alternative applications (WiFi Analyzer)

Check your router settings - the 5 GHz network may be disabled-->

Method 2: Via iPhone (iOS) Settings

On iPhone And iPad With iOS The default settings don't show the Wi-Fi frequency, but there is a workaround through diagnostics menuThis method works on all models starting from iPhone 6s (including iPhone 15), but requires the execution of a hidden command.

1. Open the app Telephone and dial the combination: *#5005*7672# (this is the code to check the settings SMS, but it opens a hidden menu).
2. If nothing happens, enter the alternative code: 3001#12345# and press Call.
3. You will get into Field Test Mode (network test mode).
4. Go to the section Wi-Fi or Network.
5. Find the line Frequency — the frequency in megahertz will be indicated there (for example, 2412 MHz = 2.4 GHz, 5180 MHz = 5 GHz).

If the menu does not open, try another method:

1. Connect to Wi-Fi.
2. Open Settings → Wi-Fi and tap the ⓘ icon next to the network name.
3. Remember MAC address of the router (For example, A4:1B:2C:...).
4. Open your browser and enter the following in the address bar: http://[MAC address] (For example, http://A4-1B-2C-...). Some routers display the frequency on the authorization page.

⚠️ Attention: Codes *#5005*7672# And 3001#12345# may not work on iOS 17+ due to Apple restrictions. In this case, use apps from the App Store (see Method 4).

Method 3: Android apps (WiFi Analyzer and similar)

If standard methods don't work, install one of the specialized apps. They will not only show the frequency but also analyze channel load, signal strength, and neighboring networks.

Top 3 apps for Android:

• 📊 WiFi Analyzer (from farproc): free, shows range, channel, signal level and optimization recommendations. The only application that determines the frequency even on custom firmware like LineageOS.
• 🔍 NetSpot: Builds a heat map of Wi-Fi coverage and displays frequency in real time.
• 📶 WiFi Overview 360: Detailed network information, including channel width and standard (802.11n/ac/ax).

Instructions for WiFi Analyzer:

1. Install the app from Google Play.
2. Open it and wait for the networks to be scanned.
3. Tap your network in the list.
4. In the details window, find the line Frequency or Band.
5. To analyze channels, go to the tab Channel Rating — there will be recommendations on choosing the least loaded channel.

If the application shows 5 GHz, but the speed is low, check:

• 🔌 Setting up Width (channel width) in the router - optimal for 5 GHz 40 MHz or 80 MHz.
• 📡 Distance to the router - 5 GHz does not penetrate walls well.
• 🔄 Router operating mode - if enabled 802.11b/g/n, force activation 802.11ac/ax for 5 GHz.

Method 4: iPhone apps (Network Analyzer and similar)

On iOS The choice of Wi-Fi analysis apps is limited due to policy Apple, but there are several working options:

• 📱 Network Analyzer (from Technet): shows the frequency, MAC address router and signal strength. The free version has a limit on the number of scans.
• 🌐 WiFi SweetSpots: Visualizes network coverage and displays the band (2.4 or 5 GHz) in real time.
• 🔗 Fing: Scans the network and determines the frequency through traffic analysis (requires Wi-Fi connection).

Instructions for Network Analyzer:

1. Install the app from App Store.
2. Open the tab Wi-Fi.
3. Click Scan — the application will scan available networks.
4. Select your network from the list - the frequency will be indicated in the details (2.4 GHz or 5 GHz).

If the app doesn't show the frequency, try:

• 🔄 Reconnect to the network.
• 📱 Update the app to the latest version.
• 🌍 Enable geolocation (some apps use it to determine regional channels).

⚠️ Note: On iPhone with iOS 17+ Some apps may not display the frequency due to new restrictions on Wi-Fi data access. In this case, use the router's web interface (see Method 5).

Method 5: Via the router's web interface

If your phone can't detect the frequency, the most reliable way is to access your router settings. This is a universal method that works regardless of your phone model.

1. Find out IP address router:
   • On Android: Settings → Wi-Fi → [your network] → Advanced → Gateway.
   • On iPhone: Settings → Wi-Fi → ⓘ → Router.

Open your browser and enter the address (usually 192.168.0.1, 192.168.1.1 or 10.0.0.1).

Enter your login and password (by default it is often admin/admin or indicated on the router sticker).

Go to the section Wireless network (Wireless).

Find the settings 2.4GHz And 5GHz - it will indicate whether both ranges are included and which ones SSID they broadcast.

Examples of popular router interfaces:

• TP-Link: Basic → Wireless → separate tabs for 2.4 GHz and 5 GHz.
• ASUS: Wireless → Professional → line Band.
• Keenetic: Wi-Fi network → Access point → range selection.

If there is only one network in the router settings (without splitting into 2.4/5 GHz), then the mode is enabled Smart Connect or Band Steering — the router automatically assigns devices to specific bands. In this case, the frequency can only be found through a phone or app.

How to enable separate SSIDs for 2.4 and 5 GHz

Find the option in your router settings Smart Connect or Band Steering and disable it. After that, create two separate networks with different names (for example, MyWiFi_2G And MyWiFi_5G).

Common problems and solutions

If you can't determine your Wi-Fi frequency, here are the reasons and how to fix them:

Additional tips:

• 🔄 If your phone is constantly connected to 2.4 GHz, try forget the network (Settings → Wi-Fi → [network] → Forget) and reconnect.
• 📡 For stable 5 GHz operation, place the router at a height of 1–2 meters and avoid obstacles (walls, furniture).
• 🔧 On routers with firmware DD-WRT or OpenWRT The frequency can be seen in the section Status → Wireless.

FAQ: Answers to frequently asked questions

Is it possible to find out the Wi-Fi frequency without a phone?

Yes, there are several ways:

• Through computer: V Windows open Command line and enter:

  netsh wlan show interfaces

  In the line Channel The channel number will be indicated, which can be used to determine the range (1–14 = 2.4 GHz, 36–165 = 5 GHz).

• Through router: go to the web interface (see Method 5).
• Through special programs for PC: inSSIDer, Acrylic Wi-Fi.

Why does the phone only see 2.4 GHz, but not 5 GHz?

Possible reasons:

• Hardware limitations: budget phones (eg Redmi 9A, Samsung Galaxy M11) may not support 5 GHz.
• The range is disabled in the router.: check the settings 5GHz in the web interface.
• Regional restrictions: In some countries (for example, in Russia until 2026), some 5 GHz channels were banned.
• Incompatible standards: if the router is operating in mode 802.11ac, and the phone only supports 802.11n.

To check if your phone supports 5GHz, look up its specifications on the manufacturer's website (look for the lines Wi-Fi 5 (802.11ac) or Dual-band).

How to force a connection to 5GHz on Android?

If your router broadcasts both networks, but your phone selects 2.4 GHz, do the following:

1. Separate networks in the router: create separate ones SSID for 2.4 GHz and 5 GHz (for example, MyWiFi_2G And MyWiFi_5G).
2. On your phone, connect to the network with _5G in the title.
3. If your router does not support splitting, temporarily disable 2.4 GHz (in the router settings).
4. On some firmware (for example, MIUI) you can set the priority of the range in Settings → Wi-Fi → Advanced → Wi-Fi Band.

Does Wi-Fi frequency affect ping in games?

Yes, and very importantly:

• 2.4 GHz: high latency (ping 30–100 ms) due to interference and channel congestion. Suitable for simple tasks (social media, video).
• 5 GHz: low ping (ping 5-30 ms), but only if you are close to the router. Ideal for online gaming (CS2, Fortnite, Valorant).

Recommended for gamers:

• Use 5 GHz with channel width 80 MHz.
• Turn on QoS (traffic prioritization) in a router for gaming.
• Connect via cable (Ethernet) or through Powerline adapter, if 5 GHz is unstable.

Can Wi-Fi frequency affect phone battery life?

Indirectly, yes. Network 5 GHz requires the phone's Wi-Fi module to be more active, which can increase battery consumption by 5–15%. However:

• If the 5 GHz signal is stable, the phone spends less energy, than with constant reconnections to a weak 2.4 GHz signal.
• On iPhone The difference in battery consumption between ranges is minimal thanks to optimization iOS.
• On Android You can save battery life by disabling background network scanning (Settings → Location → Wi-Fi Scan).
