In today's digital world, the speed and stability of a wireless connection are critical for work, entertainment, and communication. Users often experience slow internet speeds, not realizing that their equipment is physically incapable of delivering the speeds advertised by their provider. Wi-Fi module version — is the key factor that determines the maximum theoretical data transfer rate and frequency range available to your device.
Understanding the exact chip installed in your computer or smartphone allows you to avoid unnecessary expenses on upgrading your data plan if your hardware is simply outdated. In this article, we'll take a detailed look at software and hardware methods for identifying network adapters on various platforms.
Whether you're using a desktop PC with an external adapter or a modern Ultrabook, diagnostic methods are similar, but have their own nuances. We'll cover standard operating system tools, specialized utilities, and even the command line for advanced users.
Why is it important to know the specifications of a network adapter?
Many users mistakenly believe that if the router supports the standard Wi-Fi 6, then all connected devices will automatically start operating at maximum speed. This is a fundamental misconception, as a wireless connection always relies on the capabilities of the weakest link in the chain. If your laptop is equipped with a standard module 802.11n, it will not be able to receive the signal faster, even if the router is broadcasting a gigabit stream.
Knowing the exact adapter model is also essential when searching for drivers. Often, automatic installation via Windows Task Manager installs a generic driver, which may be unstable or lack support for certain power-saving features. The exact chip model (for example, Intel AX200 or Realtek RTL8822CE) is required to download the correct software from the manufacturer's website.
Understanding the standard versions also helps when planning new equipment purchases. If you see that your device has an older module that only operates in the 2.4 GHz band, you'll know that upgrading to a 5 GHz router won't improve speed without replacing the adapter itself.
⚠️ Note: Not all adapters with similar names support the same speeds. Modifications with the "AC" prefix typically indicate 5 GHz support, but actual speed depends on the number of antennas (MIMO).
Checking the Wi-Fi module version in Windows
The Windows operating system provides sufficient tools for basic hardware diagnostics, although the information is sometimes buried deep in menus. The easiest way is to use the built-in Device Manager, which displays all connected components.
To start, press the key combination Win + X and select "Device Manager" from the menu. In the window that opens, find the "Network Adapters" section and expand it. Here you will see a list of all network interfaces. Look for a name containing the words Wireless, Wi-Fi or 802.11.
☑️ Check in Device Manager
If the model name contains an abbreviation AC, this indicates support for the standard Wi-Fi 5The presence of the word AX speaks of the modern standard Wi-Fi 6. However, if you only see N or the absence of letter designations after the number, most likely you have an outdated device in front of you.
More detailed information can be obtained via the command line. Click Win + R, enter cmd and press Enter. In the black window, enter the command:
netsh wlan show driversIn the command output, look for the line "802.11 Radio Protocol." This is where the supported version of the standard will be listed, for example, 802.11ac or 802.11axThis is a more reliable source of information than just the device name in the device manager.
What should I do if my device has a yellow exclamation mark?
This means the driver is not installed or is working incorrectly. In this case, the system may incorrectly display the model name, calling it "Unknown Device." You should download the driver from the laptop manufacturer's website or from the chip manufacturer's hardware ID.
Diagnosing a Network Adapter in macOS
Apple Mac users can also easily access technical information about their wireless module. In macOS, this data is compiled into a convenient system report that doesn't require third-party software.
To access the data, hold down the key Option (Alt) on your keyboard and simultaneously click the Wi-Fi icon in the menu bar (upper right corner of the screen). The drop-down list will display advanced technical information. Look for the line "PHY Mode" or "Phy Mode."
The values in this line will tell you about the current connection and adapter capabilities:
- 📶 11ax — indicates operation in the Wi-Fi 6 standard (the most modern).
- 🚀 11ac — means operation in the Wi-Fi 5 standard.
- 📡 11n — the old Wi-Fi 4 standard, operating at a maximum of 450 Mbps.
- 🐢 11a/b/g — obsolete standards that are practically not used for mainstream access today.
For even more detailed information, including the exact chip model, click on the apple in the upper left corner, hold down the key Option and select "System Information" (or "System Report"). In the left menu, go to "Network" -> "Wi-Fi." In the right part of the window, in the "Interface" field, you will see the full name of the device, for example, Broadcom BCM4360.
⚠️ Note: The "PHY Mode" field displays the current connection standard. If you're connected to an older router, your Mac may display 11n even if the module itself supports 11ac. To check the module's capabilities, check the interface name.
How to check your Wi-Fi version on Android and iOS
In mobile operating systems, hardware information is often hidden from the average user, but there are ways to circumvent these limitations. Android devices offer more comprehensive diagnostic capabilities, especially if you have access to the engineering menu or third-party utilities.
Apple doesn't provide direct information about the Wi-Fi chip model in the default settings of iPhones and iPads. However, knowing the device model can accurately identify the module. For example, iPhone 6 and later support 802.11ac, and starting with the iPhone 11, the devices have a module installed Wi-Fi 6For Android, the situation is simpler: you can use analyzer apps.
One of the most popular and reliable ways is to use the app AIDA64 or CPU-ZAfter installation, launch the program and go to the "Network" section. The chipset name and supported standards will be listed there. You can also sometimes find information about the WLAN module in the standard Android settings under "About phone" -> "All specifications."
It's important to differentiate between supported frequencies. If the specifications only list 2.4 GHz, the module doesn't support the high-speed 5 GHz band. Modern flagships almost always feature dual-band modules.
Using third-party utilities for deep diagnostics
When built-in OS tools aren't enough, specialized programs come to the rescue. They let you find out not only the standard version, but also the chip manufacturer, driver version, release date, and supported encryption technologies.
One of the best free snails is HWiNFOAt startup, select "Sensors-only" or "Summary" mode to avoid overloading the system. In the device tree, find the "Network" section. It will contain a detailed description of the adapter, including its Vendor and Device ID.
Another powerful utility is AIDA64 ExtremeIt's paid, but has a trial period. Under "Network" -> "Windows Network," you can see detailed information about each network adapter, including the MAC address, real-time connection speed, and connection bus type (PCI-E, USB).
| Program | License type | Depth of analysis | For whom |
|---|---|---|---|
| HWiNFO | Free | High | Advanced users |
| AIDA64 | Paid / Trial | Maximum | Professionals, engineers |
| WiFi Analyzer | Free | Average (channels) | Regular users |
| Device Manager | Built into the OS | Basic | All users |
Using third-party software is especially useful when the driver appears in the system as a "Standard Microsoft Adapter." In this case, utilities can read information directly from the hardware, bypassing driver limitations.
Understanding Wi-Fi standards and generations
To correctly interpret the obtained data, it's important to understand the differences between wireless network generations. Marketing names often confuse users, so it's best to rely on IEEE technical designations.
Standard 802.11n Wi-Fi 4 was revolutionary in its time, introducing MIMO (multiple antenna) technology. However, its maximum speed is limited to 600 Mbps under ideal conditions, and in practice, rarely exceeds 150-200 Mbps. It operates in the congested 2.4 GHz band.
The next step was 802.11ac (Wi-Fi 5). This is the first standard to be widely implemented in the 5 GHz band. It enabled speeds exceeding 500 Mbps and 1 Gbps. If your module supports Wave 2, it can also work with multiple devices simultaneously (MU-MIMO).
Modern standard 802.11ax (Wi-Fi 6) and its improved version Wi-Fi 6E (with a 6 GHz range) are aimed not so much at increasing the peak speed of a single client, but at increasing the overall network throughput with a large number of connected devices.
⚠️ Note: Interfaces and standard names may change with the release of new router software and operating system versions. Always check the official specifications from the chip manufacturer on the Intel, Realtek, or Qualcomm website.
Frequently Asked Questions (FAQ)
Can a software update increase the Wi-Fi module version?
No, the Wi-Fi version (standard) is determined by the hardware—the chip and antennas inside the device. No driver or BIOS update will convert an 802.11n module to 802.11ac. Upgrading to a higher standard requires a physical replacement of the adapter.
Why does my router show 1000 Mbps, but the Wi-Fi speed is only 80 Mbps?
Most likely, your Wi-Fi module operates in the 2.4 GHz band (802.11n standard), where actual speeds rarely exceed 80-100 Mbps due to interference and protocol limitations. Check if the adapter supports 5 GHz and connect to a network labeled "...5G."
How do I know how many antennas (MIMO) are in my Wi-Fi module?
In Windows, this can be done via the command line: netsh wlan show interfacesFind the "Transmission Mode" line or look in the adapter's properties in Device Manager, under the "Advanced" tab. The number of antennas is often indicated in the model name (e.g., 1T1R, 2T2R).
Does Windows version affect Wi-Fi speed?
Indirectly, yes. Older versions of Windows may not have optimized drivers for new standards (such as Wi-Fi 6), resulting in compatibility mode at reduced speeds. Updating the OS often resolves network performance issues.
