A modern smartphone is a complex device with a whole host of modules responsible for wireless communication. Users often wonder how to find out the Wi-Fi version on their phone to understand why they're not achieving maximum speed or why their router is operating in a limited mode. The answer isn't always obvious, as operating system manufacturers don't always make this information readily available.
Understanding what wireless communication standard Determining whether your device supports Wi-Fi 6 is critical for setting up a home network. If you have a powerful router with Wi-Fi 6 support, but your phone only supports Wi-Fi 4, you won't be able to achieve high data transfer speeds. In this article, we'll cover all available diagnostic methods, from simple methods to using the engineering menu.
It's worth noting that information about supported protocols is often hidden deep within the system. This is done to avoid overloading the interface with unnecessary data for the average user. However, with the right tools and knowing where to look, you can get comprehensive information about WLAN module your device.
Understanding Wireless Standards
Before moving on to practical actions, it is necessary to understand the theory. Wi-Fi protocols They've evolved over decades, with each new standard bringing improvements in speed and stability. Older devices may not recognize new networks, and new phones may perform slowly on older hardware. Knowing these differences helps avoid confusion when buying new equipment.
The majority of modern mid- and high-end smartphones support the standards 802.11ac (Wi-Fi 5) and 802.11ax (Wi-Fi 6). Budget models or devices from previous years may be limited by the standard. 802.11nIt's important to understand that your phone will always operate at the speed of the slowest link in the "provider-router-phone" chain.
⚠️ Please note: Support for the 5 GHz frequency does not always mean support for the latest Wi-Fi 6 standard. Your device may operate in the 5 GHz band but use the older 802.11ac protocol, which limits the maximum theoretical speed.
For clarity, we'll look at the key characteristics of wireless communication generations in a comparison table. This will help you quickly understand the capabilities of your equipment.
| Generation | IEEE standard | Max. speed (theoret.) | Year of implementation |
|---|---|---|---|
| Wi-Fi 4 | 802.11n | up to 600 Mbps | 2009 |
| Wi-Fi 5 | 802.11ac | up to 6.9 Gbps | 2014 |
| Wi-Fi 6 | 802.11ax | up to 9.6 Gbps | 2019 |
| Wi-Fi 6E | 802.11ax | up to 9.6 Gbps | 2020 |
| Wi-Fi 7 | 802.11be | up to 46 Gbps | 2026 |
As the table shows, the performance gap between generations is colossal. If your phone only supports Wi-Fi 4, even under ideal conditions you won't be able to squeeze more performance out of your network than this standard allows. This is why checking the Wi-Fi version on Android or iPhone is so important when upgrading your home network.
Checking the Wi-Fi version on Android via Settings
In the Android operating system, the display of technical information varies from manufacturer to manufacturer. Shells Samsung One UI, Xiaomi MIUI and clean Android They provide varying levels of detail. However, a basic way to find out the current connection status is available almost everywhere.
The first step is to go to the settings menu. You need to open Settings, then select the item Wi-Fi or ConnectionsFind the network you're currently connected to and click the gear icon or arrow next to the network name. This often displays the frequency (2.4 GHz or 5 GHz) and sometimes the connection standard.
If the menu only displays the frequency, that's a clue. Operating at 2.4 GHz almost certainly means using the Wi-Fi 4 (802.11n) standard, as newer standards are oriented toward 5 GHz. However, to confirm this, you'll need to dig deeper.
On some stock Android devices (Pixel, Motorola), tapping the Wi-Fi icon in the notification shade or quick settings may display a pop-up window detailing your current connection speed. Connection speed is a great indicator. If it's below 144 Mbps or 300 Mbps, you're definitely on Wi-Fi 4. Speeds above 433 Mbps indicate Wi-Fi 5 or 6.
It's worth remembering that interfaces change. Manufacturers may hide this information in different menu sections depending on the firmware version.
⚠️ Note: The settings interface may vary depending on your phone model and shell version. If you don't find the settings you need, use the alternative diagnostic methods described below.
Using the engineering menu and hidden codes
For more advanced Android users, there's access to hidden menus that provide comprehensive technical information. This is the most reliable way to find out the Wi-Fi version on Android without installing third-party apps. However, access to these features depends on the processor and manufacturer.
The most universal method is to use a code to enter the engineering menu. Open the "Phone" app (dialer) and enter the code. ##4636##If your phone supports this code, the "Testing" menu will open. Select Wi-Fi Information or Wi-Fi statistics.
In the list that opens, look for the lines Link Speed (Connection speed) and Frequency (Frequency). There may also be a field PHY Type or Protocol, where the standard is directly stated, for example, 11ax or 11acIf these fields are not present, analyze the speed: values of 866 Mbps and above indicate Wi-Fi 6 support.
What to do if the code doesn't work?
On many modern smartphones (especially Xiaomi and Samsung), access to the engineering menu via a code may be blocked by the manufacturer. In this case, try the codes ##4636## or #0#, but they do not work on all devices.
Another option for devices based on MediaTek processors is to use code ##3646633##This opens the full engineering menu, where in the tab Connectivity -> Wi-Fi -> Wi-Fi Statistics You can see detailed information about the current connection, including the channel and modulation used.
- 📱 Enter the code in dialer:
##4636## - 📱 Select "Wi-Fi Information"
- 📱 Find the "Link Speed" or "PHY Mode" option
- 📱 Compare the speed with the standards table
Checking Wi-Fi on iPhone and iPad
In the ecosystem Apple Things are different. The company strictly controls access to system information, so standard iOS tools don't allow you to find out the exact Wi-Fi protocol version (for example, 802.11ax). The user only sees the network name and signal strength.
However, indirect methods do exist. If you're connected to a 5 GHz network and your iPhone is no older than the iPhone 6, then you're definitely using at least Wi-Fi 5 (802.11ac). All models starting with iPhone 6, support this standard. Models iPhone 11 and newer already support Wi-Fi 6.
To obtain detailed technical information on iOS, Mac owners can use the "Console" or "Wireless Diagnostics" utility by connecting the phone with a cable, but this is a more complex approach. The easiest way is to use the device model, as Apple doesn't change Wi-Fi modules within the same model depending on the region.
There's a caveat with privacy settings. In iOS 14 and later, the "Private Wi-Fi Address" feature can affect the device's appearance in the router's client list, but it doesn't hide the module's technical capabilities. If knowing the version is crucial for you, the easiest way to find the specifications for your iPhone model is on Apple's official website, under "Specifications."
Third-party diagnostic applications
When built-in tools aren't enough, specialized apps from the Google Play Market come to the rescue. They can read data directly from the Wi-Fi module's drivers and display it in an understandable format. This is the easiest method for the average user.
One of the most popular and informative applications is WiFi Analyzer or WiFi Man by UbiquitiOnce installed and geolocation permissions granted (required for network scanning), these programs display detailed information about the current connection.
In the appendix WiFi Analyzer You need to go to the "Information" tab or click on the current network. There will be a field there Standard or 802.11, where the value is specified, for example, 802.11ax or 802.11nIt also displays the channel width (20, 40, 80 or 160 MHz), which directly affects the speed.
☑️ Select an app to check
Another powerful app is Fritz!App WLAN or NetAnalyzerThey provide even more in-depth analysis, showing not only the standard but also noise levels, channel load, and signal quality in real time. This is useful not only for checking the version but also for optimizing router placement.
⚠️ Important: When installing Wi-Fi analyzer apps, pay attention to the permissions they request. Location access is required for the network scanner on Android, but access to contacts or SMS is not required and should raise red flags.
Using third-party software gives you the most complete picture. You see not only what the phone can do, but also how it's currently performing under specific conditions.
Connection speed analysis as an indicator
If you don't want to mess around with settings and apps, you can use the elimination method through speed analysis. While this won't guarantee 100% accuracy, it's a great way to determine if there's a bottleneck.
Connect to a router that supports high speeds (Wi-Fi 5/6) and run a speed test (such as Speedtest). If the router is in the same room as your phone and the Wi-Fi speed doesn't exceed 40-50 Mbps, your phone is most likely using the 2.4 GHz band and the 802.11n standard.
If the speed reaches 300-400 Mbps or higher on a gigabit plan, then your phone is definitely using at least Wi-Fi 5 (802.11ac). Wi-Fi 6 is typically capable of speeds approaching 800-900 Mbps over the air under ideal conditions.
It's important to keep in mind that actual speed is always lower than theoretical due to protocol overhead, interference, and distance. However, the order of magnitude of the numbers gives a clear understanding of your capabilities. Wi-Fi adapter.
Frequently Asked Questions (FAQ)
Can a software update add Wi-Fi 6 support to an older phone?
No, Wi-Fi support depends on the hardware. If your phone has a Wi-Fi 5 module, no system update will upgrade it to Wi-Fi 6. This is a physical limitation of the chip.
What is the difference between Wi-Fi 5GHz and Wi-Fi 6?
5 GHz is a frequency band, and Wi-Fi 6 (802.11ax) is a data transmission standard. Wi-Fi 6 can operate on both 5 GHz and 2.4 GHz, providing greater efficiency and speed than Wi-Fi 5.
Why can't my phone see the Wi-Fi 6 network?
If the router is configured in "Wi-Fi 6 Only" mode, older devices won't see the network. The network may also be hidden, or the phone may be too far from the router, where the 5 GHz signal is unstable.
Does a case affect Wi-Fi speed?
Yes, metal cases or cases with magnetic elements can shield the antenna signal, resulting in a drop in speed and switching to a lower communication standard to maintain stability.
