How to determine the Wi-Fi standard on your smartphone: from 802.11n to Wi-Fi 7

Have you ever wondered why your smartphone connects to the router at 300 Mbps, even though your plan promises 1 Gbps? Or why your phone's specifications say Wi-Fi 6, but in reality the connection is slower than the old model? The reason is often non-compliance with Wi-Fi standards between the device and the router. Knowing the exact version of the wireless module in your smartphone helps not only diagnose speed issues but also properly configure your home network—for example, select the optimal channel. 2.4 GHz or 5 GHz, enable support MU-MIMO or 160 MHz.

In this article we will look at All current methods for checking the Wi-Fi standard on Android and iPhone — from analyzing technical specifications to hidden engineering menus. You'll learn how to distinguish Wi-Fi 5 (802.11ac) from Wi-Fi 6 (802.11ax)Why don't some phones support it? 6 GHz (Wi-Fi 6E), and how to check the actual connection bandwidth. Finally, there's an FAQ with answers to frequently asked questions about standard compatibility and network optimization.

Why is it important to know your smartphone's Wi-Fi standard?

Modern smartphones are equipped with wireless modules that support standards from Wi-Fi 4 (802.11n) to Wi-Fi 7 (802.11be)The difference between them is not only in theoretical speed, but also in key technologies:

• 📶 Wi-Fi 4 (802.11n): maximum speed up to 600 Mbps, works only on 2.4 GHz (or 5 GHz (in rare cases). Outdated, but still found in budget models.
• ⚡ Wi-Fi 5 (802.11ac): to 3.5 Gbps on 5 GHz, supports MU-MIMO and channel width 160 MHz. Relevant for most devices from 2016–2020.
• 🚀 Wi-Fi 6/6E (802.11ax): to 9.6 Gbps, works on 2.4/5/6 GHz, optimized for dense networks (stadiums, offices). Support OFDMA And TWT reduces delays.
• 💎 Wi-Fi 7 (802.11be): to 46 Gbps, channel width 320 MHz, support Multi-Link Operation (simultaneous operation on several bands). Appeared in flagships of 2023–2026.

If your router supports Wi-Fi 6, and the smartphone is only Wi-Fi 5, you will never get the speed the manufacturer claims. Moreover, some features (for example, 160 MHz or 6 GHz) may simply be unavailable. Knowing the standard will help:

• 🔍 Configure your router correctly (select a compatible mode) 802.11ac/ax or 802.11n).
• 📊 Optimize channels and bandwidth for maximum speed.
• 🛒 Choose a new smartphone or router with the required standards support consciously.

⚠️ Attention: Some manufacturers (eg Xiaomi or Realme) the characteristics indicate support Wi-Fi 6, but in practice the module may not work with 160 MHz or 6 GHzAlways check the detailed specifications!

Method 1: Check in Android settings (without third-party apps)

On most smartphones running Android 10 You can find out the current Wi-Fi standard directly in the system settings. This instruction is relevant for Samsung, Google Pixel, OnePlus and other brands:

1. Open Settings → Wi-Fi.
2. Tap the name of the connected network (or click ⚙️ next to it).
3. Scroll down to the block Technical information (or Network information).
4. Find the lines:
   • Wi-Fi standard (For example, 802.11ac or Wi-Fi 6).
   • Frequency (2.4 GHz, 5 GHz or 6 GHz).
   • Channel width (20/40/80/160 MHz).

If you don't have such data, try an alternative route:

1. Go to Settings → About phone → Software info.
2. Tap the item several times Build number (activates developer mode).
3. Go back to the main settings menu, open System → Developer Mode.
4. Find the section Net or Wi-Fi — the current standard may be displayed there.

On Samsung Galaxy (One UI) another way:

1. Settings → Connections → Wi-Fi → ⚙️ → Manage networks.
2. Select your network and view the field Protocol.

⚠️ Attention: On some firmware (for example, MIUI from Xiaomi) Technical information about Wi-Fi is hidden. In this case, use method 3 or 4.

Method 2: Checking on iPhone (iOS)

On iPhone Apple doesn't provide direct information about the Wi-Fi standard in the interface, but there are workarounds. First, you can use the device model:

To accurately check the current connection:

1. Install the application AirPort Utility (free in the App Store).
2. Open Settings → Wi-Fi and tap the ⓘ icon next to your network.
3. In the block Network information look at the field Wi-Fi mode (For example, 802.11ax).

You can also use console commands (Mac or jailbreak required):

networksetup -listallhardwareports

Find the line in the output Wi-Fi and see the supported standards.

Method 3: Using third-party applications (Android)

If your system settings don't show the Wi-Fi standard, specialized utilities can help. The best ones are:

• 📊 WiFi Analyzer (from VREM Software): shows the current standard (802.11ac/ax), channel width, and signal strength. The free version is sufficient for analysis.
• 🔍 Network Analyzer (from Jiri Techet): in the section Wi-Fi displays PHY Mode (For example, VHT80 for Wi-Fi 5 with channel width 80 MHz).
• 🛠️ DevCheck: in the section Network indicates Wi-Fi Standard and supported frequencies.

Example of use WiFi Analyzer:

1. Install the application and open it.
2. Connect to your Wi-Fi network.
3. Go to the tab Connection.
4. In the block Link Speed look at the line Standard (For example, IEEE 802.11ac).

IN DevCheck the path is this:

1. Open the tab Hardware.
2. Scroll to the block Network.
3. Find the field Wi-Fi - the standard will be indicated there (for example, Wi-Fi 6 (802.11ax)) and supported frequencies.

Method 4: Checking via the engineering menu (for advanced users)

There is a hidden feature on Android smartphones engineering menu, which displays low-level data about the Wi-Fi module. This method works on 90% of devices, but requires caution - do not change the parameters if you are not sure of their purpose!

Instructions:

1. Open the app Telephone and enter the code:

   ##4636##

   On some devices (Samsung, Huawei) use:

   *#0011#

2. In the menu that opens, select Wi-Fi information (or Wi-Fi Information).
3. Please note the fields:
   • Wi-Fi Standard (For example, 802.11ax).
   • Frequency (2412 MHz = 2.4 GHz, 5180 MHz = 5 GHz).
   • Link Speed (For example, 866 Mbps).
   • Channel Width (80 MHz).

On Qualcomm Snapdragon (most flagships) a test is also available in the engineering menu Wi-Fi RF, where you can see the supported standards and maximum speeds.

⚠️ Attention: On some firmware (MIUI, ColorOS) the engineering menu may be blocked. In this case, use applications from Method 3.

adb shell am start -n com.android.settings/.TestingSettings

Method 5: Analyze the technical specifications of the smartphone

If you're unable to determine the Wi-Fi standard using software, you can always refer to the device's official specifications. Here's how to do it correctly:

1. Find your smartphone model in Settings → About phone → Model (For example, SM-G991B For Samsung Galaxy S21).
2. Go to the manufacturer's website:
   • 🌍 Samsung: samsung.com → Support → Enter model.
   • 📱 Apple: support.apple.com → Select your iPhone model.
   • 🤖 Xiaomi/Redmi/Poco: mi.com → Specifications.

Please note the nuances:

• 🔍 If specified 802.11 a/b/g/n/ac - This Wi-Fi 5.
• 🚀 If there is 802.11ax - This Wi-Fi 6 (or Wi-Fi 6E, if additionally specified 6 GHz).
• ❌ Absence 160 MHz or 6 GHz in the specifications means that the smartphone does not support these functions, even if declared Wi-Fi 6.

For a quick check, you can use the following databases:

• 📋 GSMArena: enter model → section Comms → WLAN.
• 🔎 PhoneArena: similarly, look for the block Connectivity.

⚠️ Attention: Manufacturers sometimes update specifications after a release. For example, Samsung Galaxy S22 did not support it initially Wi-Fi 6E, but in some regions this feature was added later. Always check the official website for the latest information.

Comparing Wi-Fi Standards: Which is Best for Your Smartphone?

To understand how your smartphone meets modern requirements, let's compare key standards:

Which standard to choose in 2026?

• 🏠 For home: Wi-Fi 6 (or Wi-Fi 6E, if the router supports 6 GHz). Optimal for streaming video, online gaming, and smart devices.
• 💼 For the office: Wi-Fi 6E or Wi-Fi 7 — cope better with a large number of connected gadgets.
• 📱 For a smartphone: If the device is older than 2018, it is most likely Wi-Fi 5. For new models (iPhone 12+, Samsung Galaxy S21+) is relevant Wi-Fi 6/6E.

Important: Wi-Fi 6E And Wi-Fi 7 require support from the router. If your router is older than 2020, it most likely does not broadcast the network to 6 GHz.

Common problems and solutions

Even if your smartphone supports Wi-Fi 6, you may encounter problems. Let's look at typical scenarios:

• 🐢 Slow speed on Wi-Fi 6:

  Reason: The router is configured for channel width 20 MHz instead of 80/160 MHz.

  Solution: Go to your router settings (usually 192.168.1.1) and in the section Wi-Fi select channel width 80 MHz (or 160 MHz, if supported).

• 🔌 The smartphone does not connect to 5 GHz.:

  Reason: The range is disabled in the router settings. 5 GHz or an incompatible channel is used (for example, 149–165, which are prohibited in some countries).

  Solution: Enable 5 GHz in the router settings and select the channel 36–64 or 100–144.

• 📵 Wi-Fi 6E (6 GHz) is not working:

  Reason: In your country the range 6 GHz may be banned or require certification. For example, in Russia by 2026 6 GHz permitted for limited use only.

  Solution: Check local laws or disable 6 GHz in the router settings.

If your smartphone doesn't see the network 5 GHz or 6 GHz In general, it's likely that its Wi-Fi module doesn't physically support these ranges. Check the specifications (see Method 5).

adb shell settings put global wifi_frequency_band 1

Where 1 — priority 5 GHz, 0 - balance between 2.4/5 GHz.-->
