In the age of ubiquitous digital presence, wireless connection speed and stability are becoming critical for comfortable work, gaming, and high-definition content viewing. However, many users are unaware that their equipment may not be delivering on the provider's full potential due to the use of outdated communication protocols. Understanding which one Wi-Fi standard Currently in use, it allows you to diagnose low speed issues and make informed decisions about equipment upgrades.
Modern routers and network cards support many different versions of the IEEE 802.11 protocol, commonly referred to as Wi-Fi 4, 5, 6, and later. Each of these versions has its own limitations in terms of throughput, frequency range, and signal encoding methods. If you pay for gigabit internet but are connected via an older standard, you'll lose up to 90% of the speed you paid for, often without even realizing it.
In this article, we'll take a detailed look at software and hardware methods for determining the current wireless connection version on various operating systems. You'll learn how to use built-in diagnostic tools, the command line, and specialized software to obtain accurate technical information. This knowledge will help you optimize your home network and eliminate data transfer bottlenecks.
Basic concepts of wireless network generations
Before moving on to practical diagnostics, it's important to clearly understand the difference between marketing names and technical specifications. Wi-Fi standards are regulated by the IEEE and have alphanumeric designations that are often confusing to the average user. For example, what we commonly call Wi-Fi 5 is technically called 802.11ac, and the newest standard is 802.11ax.
Each new generation brings significant improvements not only to the maximum theoretical speed, but also to the efficiency of operation in noisy environments. If older versions like 802.11n While wireless networks operated primarily in the 2.4 GHz band and suffered from interference from microwaves and Bluetooth devices, modern standards actively utilize the 5 GHz and 6 GHz bands. This allows for speeds comparable to wired connections.
It's also important to remember that connection speed is always determined by the weakest link in the chain. Even if your router supports the latest Wi-Fi 6E, but your laptop was released five years ago with a Wi-Fi 4 module, the connection will still be established using the 802.11n standard. The actual speed is always limited by the minimum standard among all data exchange participants.
Below is a table that will help you organize your knowledge about wireless network generations and their characteristics:
| Wi-Fi generation | Technical name | Year of release | Max. speed (theoret.) | Frequency range |
|---|---|---|---|---|
| Wi-Fi 4 | 802.11n | 2009 | up to 600 Mbps | 2.4 GHz |
| Wi-Fi 5 | 802.11ac | 2014 | up to 6.9 Gbps | 5 GHz |
| Wi-Fi 6 | 802.11ax | 2019 | up to 9.6 Gbps | 2.4 / 5 GHz |
| Wi-Fi 6E | 802.11ax (Extended) | 2020 | up to 9.6 Gbps | 2.4 / 5 / 6 GHz |
| Wi-Fi 7 | 802.11be | 2026 | up to 46 Gbps | 2.4 / 5 / 6 GHz |
How to determine your Wi-Fi version in Windows 10 and 11
Windows operating systems offer ample tools for viewing network information, although the interfaces have changed slightly in recent versions. The fastest way to find out your current connection standard is to use the network status window. This method requires no command input and is accessible to any user.
You need to open the network settings by following the path Control Panel → Network and Internet → Network and Sharing CenterIn the window that opens, find your active wireless connection and click the "Wireless Network" link. The dialog box that appears will display the connection speed, but to get the exact standard (protocol), click the "Wireless Network Properties" button.
In the list of properties that opens, pay attention to the "Protocol" line. This is where the system indicates which standard is currently being used. You may see entries like 802.11ac wireless network protocol or Wireless network protocol 802.11axThis is the information you need to confirm your Wi-Fi generation.
⚠️ Note: If the protocol field shows "Not Available" or there is no information, try reconnecting to the network or updating your network adapter drivers through Device Manager.
☑️ Checking network status in Windows
An alternative and more informative method is to use the command line or PowerShell. This method allows you to get a detailed report on the adapter's status. Open a terminal with administrator rights and enter the command netsh wlan show interfaces.
In the command output, look for the line "Radio type." This will display the current communication standard. It also displays the channel type, channel width, and signal strength, which is useful for comprehensive diagnostics. The command line often displays more up-to-date data than the graphical interface, which may cache information.
Using PowerShell for Deep Diagnosis
For users who prefer more advanced tools, PowerShell provides access to the network management object model. This allows you to not only view the standard name but also analyze the supported adapter operating modes. This approach is especially useful when troubleshooting complex network configurations.
Launch PowerShell and enter the following command to get the properties of the wireless interface:
netsh wlan show interfacesIn the received report, look for the field Radio type. If it is indicated there 802.11ac, then you are working on Wi-Fi 5. Meaning 802.11ax indicates that Wi-Fi 6 is working. It's important to understand that this command displays the current active connection, not the maximum capabilities of the equipment.
To find out which standards your adapter theoretically supports, you can use the command:
netsh wlan show driversThe "Supported radio types" section will list the full range of capabilities of your network card. If you only see 802.11b/g/n, even with a Wi-Fi 6 router, your computer will physically be unable to connect at high speeds. In this case, you'll need to replace the network module or install an external USB adapter.
What do the suffixes in the names of standards mean?
The letters at the end of the standard name (a, b, g, n, ac, ax) denote specific amendments and enhancements to the IEEE 802.11 protocol. For example, "n" stands for MIMO technology, and "ax" adds OFDMA for efficient operation with multiple devices.
Checking the Wi-Fi standard on macOS
Apple computer owners also have access to detailed wireless connection information hidden in system reports. macOS is known for its optimized network protocols, and you can find out the current standard using the built-in diagnostic utility.
To do this, hold down the key Option (Alt) on your keyboard and simultaneously click the Wi-Fi icon in the menu bar in the upper-right corner of the screen. The drop-down list will display advanced technical information. Look for the "Mode" or "PHY Mode" line. It will say, for example, 802.11ac or 802.11ax.
A more in-depth analysis is available through System Monitor. Go to System Settings → General → About → System Report (or click Cmd + Space and enter "System Report." In the left menu, select "Network" → "Wi-Fi."
In the right part of the window, find the "Supported PHY Modes" option. This will display your Mac's full arsenal. The current operating mode will be displayed at the top of the report window or via the Option-click menu. macOS interface It often hides technical details from the average user, but for engineers and enthusiasts, all the information is available.
Analyzing a Wireless Connection in Linux
Linux users have perhaps the most powerful set of networking tools at their disposal. Standard command-line utilities provide comprehensive information about the wireless interface's status. This is especially relevant for server environments or systems without a graphical interface.
The main tool here is the utility iw, which replaced the outdated one iwconfigTo obtain connection information, run the command:
iw dev wlan0 linkIn the command output, find the line txrate or rxrate, which often specifies the standard used (for example, VHT for 802.11ac or HE for 802.11ax). You can also use the command nmcli (NetworkManager CLI), which is more human readable:
nmcli -f active,device,ssid,bssid,chan,rate,signal,security dev wifiThis command will display a table of active connections, with the RATE column showing the current speed, and the connection details showing the protocol. If you're using desktop environments like GNOME or KDE, this information is often hidden in network settings, but the command line always provides the most accurate and up-to-date results.
⚠️ Note: In Linux, interface names may differ (wlan0, wlp2s0, wlo1). Use the commandip linkoriw devto find out the exact name of your wireless interface before entering commands.
Specialized software for detailed analysis
Built-in OS tools are sometimes insufficient, especially when you need to analyze not only your standard but also those of neighboring networks, noise levels, and channel loads. For these purposes, specialized programs exist that visualize the radio frequency spectrum.
One of the most popular utilities is WiFi Analyzer (available in Microsoft Store) or Acrylic Wi-Fi HomeThese programs generate graphs of network distribution by channel and clearly indicate the standard (802.11n/ac/ax) for each visible access point. This helps you understand what standard your neighbors are using and whether switching to a different band makes sense.
Another powerful tool is AIDA64In the Network → Windows Network section, you can find detailed information about your network adapter, including supported and active protocols. Professionals also use Wireshark for traffic sniffing, where network capabilities, including supported standards, can be seen in the headers of management frames (Beacon frames).
Using third-party software offers the advantage of historical data and graphs. You can track how the connection standard changes as you move around your apartment. It's common for a computer to latch onto 5 GHz (Wi-Fi 5) in one room, while in another, due to a weak signal, it drops to 2.4 GHz (Wi-Fi 4). Dynamic switching — normal behavior, but knowing about it helps to place the router correctly.
Why the speed does not match the stated one
Users often encounter situations where a seemingly modern Wi-Fi 5 or 6 standard fails to deliver the expected speed. The reasons may lie in the nuances of protocol implementation, such as channel width. The 802.11ac standard can operate on channels of 20, 40, 80, and even 160 MHz. If the router is configured for 20 MHz, speed will be low, despite the new standard.
Another factor is the number of antennas and MIMO support. If the router has four antennas and supports 4x4 MIMO, but the laptop only has two antennas (2x2 MIMO), the connection will be established using the lowest common denominator. Distance and the presence of obstacles also play a role: reinforced concrete walls can cut the 5 GHz signal more than the 2.4 GHz signal, forcing the device to switch to a slower standard.
Don't forget about drivers either. Outdated network adapter software may not support new Wi-Fi 6 features, such as TWT (Target Wake Time) or OFDMA. Regularly updating drivers from the laptop or chipset manufacturer's website (Intel, Realtek, Qualcomm) is essential for stable operation.
The final speed also depends on encryption. Using older security methods (WEP, TKIP) can limit the speed to 54 Mbps even on modern equipment. Always use WPA2-AES or WPA3 to ensure maximum performance and safety.
Frequently Asked Questions (FAQ)
Can a Wi-Fi 6 router work with Wi-Fi 4 devices?
Yes, Wi-Fi standards are fully backward compatible. A Wi-Fi 6 (802.11ax) router will seamlessly accept a connection from a Wi-Fi 4 (802.11n) device. However, the paired connection will operate at the standards of the older device, meaning it will operate at Wi-Fi 4 speeds and technologies. To take advantage of the new router, the client device must also support the corresponding standard.
Does the provider's tariff affect the displayed Wi-Fi standard?
No, your ISP's data plan determines the maximum download speed from the internet, but it doesn't affect the wireless connection protocol within your local network. The Wi-Fi standard depends solely on the capabilities of your router and computer's network adapter. However, if your ISP offers 100 Mbps speeds, you may not notice any difference between Wi-Fi 4 and Wi-Fi 5 in everyday use.
How can I increase speed if I have an old laptop?
If your laptop only supports Wi-Fi 4 (802.11n), but your router is modern, the most effective solution is to purchase an external USB Wi-Fi adapter with Wi-Fi 5 or Wi-Fi 6 support. This is an inexpensive device that plugs into a USB port and allows your computer to operate at high speeds, bypassing the limitations of the built-in card.
Is it true that Wi-Fi 6E only works in new countries?
The 6 GHz band used by Wi-Fi 6E is regulated by government agencies in each country. In some regions, it's already open for use, while in others, it's occupied by military or intelligence agencies. Therefore, even if your adapter supports the standard, the 6 GHz network may not display or be selectable in certain locations.
