How to determine the Wi-Fi router frequency from your phone: 2.4 GHz or 5 GHz?

You've connected to your home or office Wi-Fi network, but you don't know what frequency your router is using. 2.4 GHz or 5 GHzThis information is critical if you're setting up smart devices, optimizing internet speed, or troubleshooting connection issues. Unfortunately, most routers don't display the network frequency in their name (SSID), and access to the administrator's web interface isn't always available.

Fortunately, Android And iPhone allow you to determine the Wi-Fi frequency without additional equipment. In this article, we'll look at 5 proven methods, including hidden phone settings, specialized apps, and network traffic analysis. You'll learn how to distinguish 802.11n (2.4 GHz) from 802.11ac (5 GHz), even if the router uses the same name for both networks.

Important: These methods work on most modern smartphones (2018 and newer), but some features may be missing on budget models or devices with custom firmware. If your phone doesn't support one of the methods, proceed to the next.

1. Standard Wi-Fi settings on Android (without apps)

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

1. Open Settings → Wi-Fi.
2. Click on the name of the network (SSID) you are connected to.
3. Scroll down to the section Technical information or Additionally.
4. Find the line Frequency, Range or Standard.

The following values ​​may be present here:

• 📡 2.4 GHz - if specified 802.11b/g/n or simply 2.4 GHz.
• 📶 5 GHz - if specified 802.11a/n/ac/ax or 5 GHz.
• ❓ Uncertain - if it is written only 802.11n (This standard works on both frequencies).

On some firmware (for example, MIUI on Xiaomi or ColorOS on Oppo/Realme) The path may vary. If you can't find the section with the frequency, try the following method.

⚠️ Attention: On Samsung With One UI the frequency may be hidden behind a button ⚙️ Network Management → AdditionallyIf you don't have one, use the app. Wi-Fi Analyzer (see section 3).

2. Hidden engineering menus on Android (for advanced users)

If the standard settings do not show the frequency, you can look in engineering menu phone. This method works on most devices, but requires caution—don't change settings unless you're sure what they're for!

Instructions for Qualcomm-processors (most Samsung, Xiaomi, OnePlus):

1. Open the app Telephone.
2. Enter the combination: ##4636##.
3. Select Wi-Fi Information (Wi-Fi information).
4. Look at the line Frequency - there will be a value in megahertz (for example, 2412 = 2.4 GHz, 5180 = 5 GHz).

For Mediatek-processors (many Redmi, Tecno, Infinix):

1. Enter in your phone: ##36446337##.
2. Go to Connectivity → Wi-Fi.
3. Find Channel — channels 1–14 belong to 2.4 GHz, 36–165 to 5 GHz.

⚠️ Note: Not all carriers and firmware versions support these codes. If nothing happens after entering them, your phone does not support this engineering menu. Do not try other combinations at random!

What should I do if the engineering menu doesn't open?

On some phones (eg. Huawei or Google Pixel) The engineering menus are blocked. In this case, use the apps in section 3 or check the frequency using another phone.

3. Wi-Fi analysis apps (the most reliable method)

If the previous methods don't work, install one of the specialized apps. They will not only show the frequency but also visualize all available networks around you.

How to use Wi-Fi Analyzer:

1. Install the app from Google Play.
2. Open it and wait for the networks to be scanned.
3. Find your network in the list - in the column Standard the protocol will be indicated (802.11ac = 5 GHz, 802.11n can be anything).
4. For accuracy, go to the tab Channel Rating — 2.4 GHz networks are marked in green, 5 GHz in blue.

Find your network in the list|Look at the Standard column|Compare with the protocol table below|Use the Channel Rating tab for visual differentiation-->

Compliance with standards and frequencies:

• 🔹 802.11a - only 5 GHz.
• 🔹 802.11b/g - only 2.4 GHz.
• 🔹 802.11n — both ranges (you need to watch the channel).
• 🔹 802.11ac/ax - only 5 GHz (But Wi-Fi 6E supports 6 GHz as well).

4. Hidden feature on iPhone (without jailbreak)

On iPhone Apple hides Wi-Fi frequency information in the default settings, but it can be retrieved using a utility. AirPort UtilityHere's how:

1. Download the free app AirPort Utility from App Store.
2. Open Settings → AirPort Utility.
3. Turn on the switch Wi-Fi Scanner.
4. Return to the main menu of the application and press Wi-Fi Scan in the upper right corner.
5. Wait for the scan and find your network in the column CHANNEL will be the channel number:
   • 📌 Channels 1–14 → 2.4 GHz.
   • 📌 Channels 36–165 → 5 GHz.

If you have iOS 14 and newer, but option Wi-Fi Scanner missing - please update AirPort Utility to the latest version or use an alternative method:

1. Connect to Wi-Fi.
2. Open Settings → Wi-Fi and click on the symbol ⓘ next to the network name.
3. Copy Router IP address (For example, 192.168.1.1).
4. Enter this address in Safari and log in to the router's web interface (login/password is usually on a sticker on the back).
5. In the section Wireless or Wireless network look at the frequency.

⚠️ Note: On some routers (e.g., those from ISPs), the web interface may be blocked. In this case, use the Wi-Fi analysis apps from Section 3.

5. Determining the frequency by network name (SSID)

Many modern routers automatically add suffixes to the network name (SSID), indicating frequency. For example:

• 📛 MyWiFi_2G or MyWiFi-2.4GHz → 2.4 GHz.
• 📛 MyWiFi_5G or MyWiFi-5GHz → 5 GHz.
• 📛 MyWiFi_PLUS or MyWiFi_AX → usually 5 GHz (but not always).

If your router is from a provider (for example, Rostelecom, Beeline, MTS), check the standard suffixes:

Provider	2.4 GHz suffix	5 GHz suffix
Rostelecom	_2G, _leg	_5G, _plus
Beeline	-2.4, _std	-5, _fast
MTS	_normal	_high
DOM.RU	_basic	_premium

If the network name does not contain any clear indication of frequency, but you see two networks with the same beginning (for example, HomeWiFi And HomeWiFi_5G) - the second one almost always works on 5 GHz.

6. Alternative methods (if nothing helps)

If none of the methods worked, try these options:

• 🔧 Checking via another phone/tablet: Take a second smartphone (preferably one with Android) and repeat steps from section 1 or 3.
• 🖥️ Via computer:
  1. On Windows: open Command line and enter:

     netsh wlan show interfaces

     Find the line Channel — channels 1–14 = 2.4 GHz, 36–165 = 5 GHz.

  2. On Mac: hold Option (⌥) and click on the Wi-Fi icon in the menu bar - information about the frequency will appear.
6. 📄 Router documentation: Find the router model (on the sticker) and check in Google its characteristics. For example, TP-Link Archer C6 supports both ranges, and Tenda N301 - only 2.4 GHz.

If you rent a router from a provider, the frequency may depend on your plan. For example, some carriers limit 5 GHz for basic packages. Check this in your account or with support.

FAQ: Frequently Asked Questions about Wi-Fi Bandwidth

My phone shows 802.11n — is it 2.4 or 5 GHz?
Standard 802.11n works on both frequenciesTo determine the exact range, look at the channel number:
• Channels 1–14 → 2.4 GHz.
• Channels 36–165 → 5 GHz.

If the channel is not displayed, use the app Wi-Fi Analyzer.

Is it possible to find out the Wi-Fi frequency without connecting to the network?

Yes, but only with the help of scanner applications (for example, NetSpot or Wi-Fi Analyzer). They show all available networks around you, including their frequencies, even if you are not connected to them.

Please note: Some routers hide the SSID, and such networks will not be displayed in the scanner.

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

Possible reasons:

• 📵 Your phone does not support 5 GHz (applicable to older models before 2015).
• ⚙️ The 5 GHz band is disabled on the router (check the settings).
• 🔄 Mode enabled Smart Connect, and the phone automatically connects to 2.4 GHz.
• 📡 Weak 5 GHz signal (this range penetrates walls worse).

To check if your phone supports 5GHz, look up its model in the specifications on the manufacturer's website.

How to force connection to 5 GHz if the phone selects 2.4 GHz?

If your router broadcasts two separate networks (for example, MyWiFi_2G And MyWiFi_5G), just connect to the network with the suffix 5G.

If there is only one network (mode Smart Connect), but you want to force it to use 5 GHz:

1. Go to your router settings (192.168.1.1 or 192.168.0.1).
2. Turn it off Smart Connect (may be called Band Steering).
3. Enable separate names for 2.4 and 5 GHz.
4. Connect to the 5GHz network manually.

Is 5GHz Wi-Fi harmful to health?

There is no scientific evidence that Wi-Fi (both 2.4 GHz and 5 GHz) is harmful to human health. does not existThe router's radiation power is hundreds of times lower than the maximum permissible standards established WHO And Federal Communications Commission (FCC).

5 GHz is even safer in terms of exposure, as the signal attenuates more quickly in space and is less penetrating. However, if you're concerned about this, you can:

• Turn off Wi-Fi at night.
• Use a wired connection (Ethernet) where possible.
• Place the router away from places where you will spend a long time (for example, not next to your bed).
