Method 1: View specifications on the manufacturer's website|Method 2: Use an analyzer app (Android)|Method 3: Check the engineering menu (##4636##)|Method 4: MAC Address Analysis (for advanced users)|Method 5: Speed ​​Test on Different Frequencies-->

1. Official Specifications: Where to Find Wi-Fi Information

The most reliable, but often ignored, way is to study technical specifications your phone model on the manufacturer's website. However, there are pitfalls: brands like Apple or Samsung They may hide details about the wireless module under general phrases like "latest-generation Wi-Fi support." We'll explain how to find accurate information.

For Android-devices:

• 🔍 Go to the manufacturer's website (for example, Xiaomi, Realme, Google Pixel) and find your model's page.
• 📄 Look for the section "Specifications" → "Wireless networks" or "Connectivity".
• 🔧 Please pay attention to the wording:
  • Wi-Fi 6 (802.11ax) — support for the 2019 standard, speed up to 9.6 Gbps.
  • Dual-band (2.4GHz + 5GHz) - operation on two frequencies.
  • Tri-band (2.4GHz + 5GHz + 6GHz) - support Wi-Fi 6E (only for 2021+ flagships).

For iPhone:

• 🍎 Apple never specifies standards Wi-Fi in marketing materials. Visit Apple support site → select a model → “Technical specifications”.
• 🔎 In the "Wireless" section, look for mentions 802.11ax (Wi-Fi 6) or 802.11ac (Wi-Fi 5). For example, iPhone 15 Pro supports Wi-Fi 6E, A iPhone SE (2022) - only Wi-Fi 5.

⚠️ Note: Manufacturers can update wireless modules within a single model without changing the name. For example, Samsung Galaxy S22 may have chips in different regions Qualcomm or Exynos with varying support Wi-Fi.

2. Engineering Menu: Hidden Wi-Fi Data on Android

If official specifications are unavailable or in doubt, Android can be used engineering menu — a hidden section with technical information. This method works on 90% of devices, but requires caution: don't change settings unless you're sure what they're for!

Instructions:

1. Open the Phone app and enter the combination:

   ##4636##

   (on some models Xiaomi or Huawei may be required ##2846579## → «ProjectMenu» → «Network Setting»).

2. Select Wi-Fi Information (Wi-Fi information).
3. Please note the fields:
   • Wi-Fi driver version — driver version (indirectly indicates the standard).
   • Frequency — current connection frequency (24xx — 2.4 GHz, 5xxx — 5 GHz).
   • Link speed — maximum connection speed (for example, 866 Mbps corresponds Wi-Fi 5).

Example of transcript:

What to do if the engineering menu is blocked?

On some firmware (for example, MIUI or ColorOS) access to the engineering menu is limited. An alternative is to use applications like DevCheck or CPU-Z, which read data about the Wi-Fi chip from the system.

⚠️ Attention: On devices with Android 12+ Some manufacturers hide Wi-Fi information in the engineering menu due to privacy policies. In this case, proceed to the next method.

3. Analyzer apps: quick analysis without root

If you don't want to mess around with settings, install one of the specialized apps. They'll not only show you the supported standards Wi-Fi, but will also analyze the signal quality, channel load, and even suggest optimal settings for the router.

Top 3 apps for Android:

• 📊 WiFi Analyzer (from farproc) - shows ranges (2.4/5/6 GHz), supported standards and signal strength.
• 🔧 DevCheck — in the “Network” section displays the Wi-Fi chip model (for example, Broadcom BCM4375 or Qualcomm WCN6855) and its capabilities.
• 📡 NetSpot — scans networks and determines the maximum connection speed (indirectly indicates the standard).

For iPhone the choice is more modest due to restrictions iOS, but you can use:

• 🍏 AirPort Utility (built-in application) - shows the current frequency (2.4 or 5 GHz) and the channel width.
• 📶 WiFi SweetSpots - analyzes signal strength and supported channels.

Example of working with DevCheck:

1. Install the app from Google Play.
2. Open the "Hardware" → "Network" tab.
3. Find the line Wi-Fi — the chip model will be indicated there (for example, Qualcomm FastConnect 6900).
4. Enter the chip name into a search engine - the first results will include its specifications (for example, "supports Wi-Fi 6E, 6 GHz, speed up to 3.6 Gbps").

4. Connection test: practical verification of standards

Theory is good, but how do you know? is it real? Does your phone support the stated standards? Test your connection to networks with different specifications. This method requires a router that supports Wi-Fi 5/6/6E or access to public networks (for example, at airports or co-working spaces).

Verification algorithm:

1. Step 1. Find out what networks are available in your area. To do this:
• On Android: open settings Wi-Fi → “Advanced” → “Wi-Fi Scanner”.
• On iPhone: use the app AirPort Utility.

Step 2. Identify neighboring network standards by their names (SSID):

• 🔄 Networks with suffixes _5G or 5GHz operate at a frequency of 5 GHz (but it is not a fact that this is Wi-Fi 6).
• 🌐 Networks with _6G or 6GHz - This Wi-Fi 6E (only for 2021+ phones).
• Step 3. Connect to the network and check the speed via SpeedtestCompare with theoretical limits:

  Wi-Fi standard	Max. speed (theory)	Real speed (practice)
  Wi-Fi 4 (802.11n)	600 Mbps	100–200 Mbps
  Wi-Fi 5 (802.11ac)	3.5 Gbps	300–800 Mbps
  Wi-Fi 6 (802.11ax)	9.6 Gbps	600–1200 Mbps

Critical point: If your phone connects to the 5 GHz network, but the speed does not exceed 300 Mbps, most likely it is using an outdated standard 802.11n (Wi-Fi 4) instead 802.11ac/ax.

5. MAC Address Analysis: A Method for Advanced Users

This method is suitable for those who are ready to delve into technical details. MAC address The phone's Wi-Fi module contains information about the chip manufacturer, which can be used to determine the supported standards. The method works on Android and requires access to ADB (Android Debug Bridge).

Step-by-step instructions:

1. Turn on Developer mode on the phone:
   • Go to Settings → About phone → Build number.
   • Tap the build number 7 times until you see the notification "You are now a developer".
• Activate USB debugging in the developer settings.
• Connect your phone to your PC and run the command in ADB:

  adb shell cat /sys/class/net/wlan0/address

  (If wlan0 it doesn't work, try wifi0 or eth0).

• The first 6 characters of the MAC address (eg. 00:1A:79) is the manufacturer's identifier (OUI). Enter them into the database. MAC Vendorsto find out the brand of the Wi-Fi chip.
• By chip model (for example, Broadcom BCM4359) find its specifications on the manufacturer's website.

Examples of chip and standard compliance:

• 🔧 Qualcomm FastConnect 6800 — Wi-Fi 6E, 6 GHz, speed up to 3.6 Gbps.
• 🔧 Broadcom BCM4375 — Wi-Fi 5, 5 GHz, speed up to 867 Mbps.
• 🔧 MediaTek MT7915 — Wi-Fi 6, 2.4/5 GHz, speed up to 1.8 Gbps.

⚠️ Please note: Some manufacturers (eg. Apple) use custom chip designations that are not displayed in public databases. In this case, the method will not work.

6. Router Compatibility: How to Choose the Optimal Equipment

Knowledge of standards Wi-Fi, supported by your phone, will help you save on buying a router. There's no point in buying a flagship model with Wi-Fi 6E, if your smartphone is limited Wi-Fi 5The table below provides recommendations for choosing a router based on your phone's specifications.
