The speed of your smartphone's wireless connection directly depends on what kind of Wi-Fi standard It's capable of supporting it. Many users purchase powerful routers with support for the latest protocols, but they don't see any speed gains because their mobile device simply can't handle high frequencies or new modulation technologies. Understanding your device's technical specifications helps you avoid unnecessary expenses and properly configure your home network.
In this article, we'll take a detailed look at ways to determine the wireless module version hidden in operating system interfaces and hardware specifications. You'll learn how to read manufacturer markings and use specialized software to obtain accurate information about radio module your device.
It often happens that the phone connects to the network, but works significantly slower than the provider's plan allows. This is a classic sign of non-compliance with standards: the router distributes the signal over Wi-Fi 6, and the phone receives it using the old protocol 802.11nTo bridge this gap, you need to accurately identify your smartphone's capabilities.
Major generations of wireless communication standards
Before diagnosing a specific device, it's important to understand the evolution of technology. All modern standards are based on IEEE 802.11 specifications, but for the convenience of users and marketers, they have simplified names. Understanding these differences is critical to understanding why your phone might not be able to detect the 5 GHz network.
The most common, but already morally outdated standard is 802.11n, also known as Wi-Fi 4. It operates in the 2.4 GHz and 5 GHz bands, but the maximum theoretical speed is limited to 600 Mbps, and in practice, it rarely exceeds 150 Mbps. If your smartphone only supports this protocol, no next-generation router will be able to increase the data transfer speed above this threshold.
More modern devices support 802.11ac (Wi-Fi 5) and 802.11ax (Wi-Fi 6). These standards require mandatory support for the 5 GHz band and offer significantly higher speeds thanks to an expanded channel and MU-MIMO technology. Support for these protocols is what users most often look for when purchasing a new gadget.
- 📶 Wi-Fi 4 (802.11n) — a basic standard that operates at up to 600 Mbps, often found in budget models of previous years.
- 🚀 Wi-Fi 5 (802.11ac) — the current minimum for comfortable use, provides speeds of up to several Gbps in the 5 GHz range.
- ⚡ Wi-Fi 6 (802.11ax) — the latest standard for flagships, reducing latency and allowing you to connect more devices without losing speed.
⚠️ Please note: Support for the 5 GHz band does not always mean support for Wi-Fi 6. Many mid-range phones only support Wi-Fi 5 (ac), even if they see 5 GHz networks.
Checking specifications through Android settings
In the Android operating system, information about supported standards is often hidden deep in menus or encoded in technical specifications. The easiest, but not always accurate, way is to check the connection status. If you're connected to a 5 GHz network, your phone definitely supports standards higher than 802.11n, but this doesn't mean it supports Wi-Fi 6.
For more accurate data, please refer to the section Settings → About phone → SpecificationsManufacturers sometimes indicate the protocol version here, but most often this information is hidden. In such cases, searching for the processor model or Wi-Fi module online by code name can help.
There is also a hidden engineering menu accessible by entering a code in the dialer. Enter the command ##4636## (This does not work on all firmware versions.) If the menu opens, select Wi-Fi Information. The current connection standard may be displayed there, for example 802.11ax, which will confirm support for the latest generation.
It's important to understand that the user interfaces of Samsung, Xiaomi, and Huawei differ greatly. Some require you to tap the build number seven times to activate developer mode, while others require using specialized diagnostic apps. There's no universal solution for all devices, so it's often easier to use third-party software.
Diagnostics on iPhone and iPad
In the ecosystem Apple Things are a bit different. The company doesn't provide users with detailed technical information about the Wi-Fi module version in the standard settings interface. You won't find the line "Protocol: 802.11ax" there. However, knowing the device model allows you to determine its capabilities with 100% certainty, as Apple strictly standardizes components.
All iPhones, starting with model iPhone 6, support the standard 802.11ac (Wi-Fi 5). This means that any relatively modern iPhone is capable of operating in the 5 GHz range. Support for the latest standard Wi-Fi 6 appeared only in the line iPhone 11 and all subsequent models, including the second generation SE.
If you have an iPad, the situation is similar. Tablets with Wi-Fi 6 support began shipping in 2020 (iPad Pro 2020, iPad Air 4). Older models, even if they receive iOS updates, physically lack the antennas and chips to work with the new protocol.
Does iPhone 13 support Wi-Fi 6E?
No, Wi-Fi 6E (extended 6 GHz) is only supported in the iPhone 15 series and later. The iPhone 13 uses Wi-Fi 6.
For a more accurate check, you can use a Mac computer. If you connect your iPhone with a cable and run System report, in the USB or Wi-Fi section (depending on the connection type and macOS version), information about the paired device is sometimes forwarded, but it is more reliable to simply check the compatibility table below.
Using third-party applications for analysis
The most reliable way to get comprehensive information is to install a specialized application from the store. Google Play or App StoreThese programs read data directly from the wireless module drivers and display it in a user-friendly format. They display not only the current standard but also all supported protocols.
One of the most popular utilities is WiFi Analyzer or WiFi Man from Ubiquiti. After launching the app, go to the connection information section. This will show your current communication standard, for example 802.11ac or 802.11axIf the application only shows 802.11n, which means either the router is old or the phone does not support higher speeds.
Another powerful tool is CPU-Z or AIDA64. In the section Device → Wi-Fi You can see detailed information about the chip. Please pay attention to the field Link Speed (connection speed). If it shows values above 433 Mbps, your phone definitely supports standards higher than basic Wi-Fi 4.
- 📱 WiFi Man — an excellent application for signal analysis and standards verification, completely free and without unnecessary fluff.
- 🔍 Fing — a powerful network scanner that also shows connection details and security type.
- 🛠️ Network Analyzer - a professional tool that shows technical details including channel width and standard.
⚠️ Note: Apps can only display the standard currently in use. If you're connected to a 2.4 GHz router, your phone may display 802.11n even if it's capable of 802.11ac. To check, switch to a 5 GHz network.
Analysis by processor model and device code
If you don't want to install unnecessary apps, you can use deduction. Knowing the processor (SoC) model installed in your smartphone can tell you exactly which Wi-Fi module is built into it. Chip manufacturers (Qualcomm, MediaTek, Huawei HiSilicon) clearly define the specifications of their solutions.
For example, processors Qualcomm Snapdragon The 600 and 700 series, released after 2018, almost always have a built-in module Wi-Fi 5. Flagship chips of the 800 series (e.g. 865, 888, 8 Gen 1) support Wi-Fi 6Budget MediaTek Helio solutions may be limited to Wi-Fi 4 only.
You can find out the processor model through the application AIDA64 or simply search for the phone model name online (e.g., "Samsung Galaxy A52 specs"). Specifications on sites like GSMArena always list the supported standard in the section Comms or WLAN.
It's also worth considering that some manufacturers may use identical processors but install different antenna modules to reduce cost. Therefore, matching by processor provides a 95% probability, but not a 100% guarantee.
Comparison table of standards and compatibility
To quickly navigate the specifications, use the table below. It will help you match the standard name with its technical specification and the approximate year of release of devices supporting it.
| Wi-Fi generation | Technical standard | Frequency ranges | Examples of devices |
|---|---|---|---|
| Wi-Fi 4 | 802.11n | 2.4 GHz, 5 GHz | iPhone 4, Samsung Galaxy S3, budget phones before 2016 |
| Wi-Fi 5 | 802.11ac | 5 GHz (main) | iPhone 6 and later, Xiaomi Redmi Note 8 and later |
| Wi-Fi 6 | 802.11ax | 2.4 GHz, 5 GHz | iPhone 11 and later, Samsung Galaxy S20 and later |
| Wi-Fi 6E | 802.11ax (Ext) | 2.4, 5, 6 GHz | iPhone 15, flagships with Snapdragon 8 Gen 2 |
As the table shows, the transition to a new standard is usually accompanied by a change in device generation. If your phone is more than 5-6 years old, the likelihood of supporting modern high-speed protocols is close to zero.
☑️ Compatibility check
The impact of the standard on real internet speed
Many users mistakenly believe that Wi-Fi 6 support will automatically give them 1 Gbps speeds. This is not true. Actual speed is limited by the weakest link in the chain: your provider's plan, the router's power, the quality of your cable, and, finally, your phone's capabilities.
However, the difference between the standards becomes noticeable in conditions of “polluted” airwaves, when there are many neighboring networks around. Wi-Fi 6 Uses OFDMA technology, which allows for more efficient channel resource distribution between devices. As a result, gaming ping becomes more stable, and video buffering stops, even if the absolute speed hasn't changed significantly.
If you have a plan with speeds above 500 Mbps, then without Wi-Fi 5 (ac) or Wi-Fi 6 (ax) support, you simply won't be able to utilize the full bandwidth. With the older 802.11n standard, speeds won't physically exceed 150-200 Mbps in real-world conditions.
⚠️ Please note: Technical specifications and application interfaces may be updated by manufacturers. For up-to-date information on standard support for a specific model, always check the vendor's official website.
Frequently Asked Questions (FAQ)
Could a software update add Wi-Fi 6 support?
No, that's impossible. Support for Wi-Fi standards is determined by the hardware—the chip and antennas built into the phone during manufacturing. No Android or iOS update can change the physical properties of the radio module.
Why does my phone see the 5 GHz network but not connect to it?
This could be due to several reasons: an incorrect password, a security standard mismatch (for example, your phone doesn't support WPA3), or a weak signal. Also, check if your router has reached its maximum number of connected devices.
What is the difference between Wi-Fi 6 and Wi-Fi 6E?
The main difference is support for the additional 6 GHz frequency band. The 6E standard allows for (avoiding) airwave congestion in older bands, but it requires not only a phone but also a dedicated router with 6E support.
How do I know if my phone is running at its maximum speed right now?
Use apps like Speedtest by Ookla or Fast.com. Compare your results with your provider's plan. If the speed is significantly lower (for example, your plan is 500 Mbps but you're getting 80 Mbps) and you're close to a router, your connection is most likely using an older standard.
