How to find out what standard your Wi-Fi uses

Page loading speeds, video call stability, and lag-free gaming directly depend on how modern your network's wireless connection is. Many users aren't even aware that their new smartphone might be running at speeds limited by an older router, or, conversely, that a powerful router might be distributing internet using an outdated protocol. Understanding this... What is the Wi-Fi standard? used right now is the first step to troubleshooting connection issues.

It often happens that a provider offers a gigabit plan, but the actual speed barely reaches 20 Mbps. This is a classic sign that devices have "agreed" to operate at the lowest common denominator. In this article, we'll examine in detail how to identify communication protocols, learn how to read technical specifications, and understand why the markings on the router box may differ from the actual speed at any given time.

The difference between theoretical throughput and actual performance can be dramatic. If you're planning a hardware upgrade or simply want to get the most out of your current plan, you need to know exactly what you're dealing with. We'll cover software and hardware diagnostic methods that don't require in-depth knowledge of network technologies.

Main generations of wireless networks and their differences

The IEEE (Institute of Electrical and Electronics Engineers) has developed a family of standards 802.11, which have evolved over decades. Each new standard has brought improvements in speed, range, and the ability to support multiple devices simultaneously. Understanding these differences is critical, as backward compatibility Allows new devices to work with old ones, but at reduced speeds.

For a long time the most common was the standard 802.11n, also known as Wi-Fi 4. It brought dual-band support and MIMO technology, significantly improving coverage. However, today it is being replaced by faster protocols such as 802.11ac (Wi-Fi 5) and the latest 802.11ax (Wi-Fi 6), which delivers gigabit speeds and lower latency.

For user convenience, the Wi-Fi Alliance has introduced simplified generation numbering. Now, there's no need to memorize complex alphanumeric codes. It's enough to know that Wi-Fi 6 is faster and more efficient than Wi-Fi 5, which in turn is superior to Wi-Fi 4. Below is a table to help you understand the key specifications.

⚠️ Attention: The speeds listed in manufacturers' tables are theoretical maximums under ideal laboratory conditions. Actual speeds are always lower due to interference, distance, and the number of connected clients.

Checking the Wi-Fi standard on Android smartphones

Android mobile devices provide fairly detailed information about their current network connection, although the depth of the data depends on the operating system version and the manufacturer's shell. The easiest way is to look in the connection settings. Typically, the path looks like this: Settings → Connections → Wi-Fi, where you need to click on the name of the active network or the gear icon next to it.

In the menu that opens, look for the "Protocol" or "Standard" field. It may contain a value like 802.11ac or Wi-Fi 5If you see 802.11n, which means the connection is slower, even if the router supports high speeds. This often happens when the phone is far from the access point or operates on the 2.4 GHz band.

For more in-depth diagnostics, you can use specialized applications such as Wi-Fi Analyzer or Wifi ManThey show not only the current standard, but also the channel width, signal strength, and airtime load. This helps understand why speeds may drop during certain hours.

• 📱 Go to Wi-Fi settings and select your active network.
• 🔍 Find the "Protocol" line to view the standard version.
• 📡 Pay attention to the frequency: 5 GHz is more often associated with AC/AX, and 2.4 GHz with N.
• 🛠 Use third-party applications for detailed signal and channel width analysis.

How to find out the Wi-Fi standard on iPhone and iPad

The iOS operating system is notoriously closed, and Apple does not provide users with direct access to technical connection details, such as the current protocol. 802.11, through the standard settings menu. You won't find a line with the value there. 802.11ax or 802.11acHowever, there are indirect methods and exceptions.

Owners of devices running iOS 14 and later may see a Wi-Fi 6 icon (a small number 6 next to the Wi-Fi icon) in the Control Center or status bar if they're connected through a router that supports this standard and the compatibility feature is enabled. If the icon isn't present, it doesn't guarantee compatibility with the older standard, but it's more likely.

Getting accurate information on an iPhone often requires using a computer. By connecting the device to a Mac, you can launch the utility. Console (Console) or use developer tools to monitor connection logs, which will show the negotiated rate and protocol. On Windows, this is more difficult to do without jailbreaking or special corporate profiles.

⚠️ Attention: The iOS interface may change with the release of new versions. If you don't see the Wi-Fi 6 indicator, it doesn't mean it's not working—Apple hides this information to simplify the interface.

An alternative method is speed analysis. If your plan allows 500 Mbps and your router supports AC/AX, but your iPhone shows speeds around 40-50 Mbps, it's likely you're using a standard connection. 802.11n in the 2.4 GHz band. In this case, it's worth checking your router settings.

Diagnosing connections on Windows computers

In Windows 10 and 11, Wi-Fi standard information is hidden a bit more deeply than in mobile operating systems, but it's accessible without installing any additional software. The fastest way is to use the command line. Win + R, enter cmd and press Enter. In the black window, enter the command:

netsh wlan show interfaces

In the list of parameters, find the line "Radio type". It will indicate the value, for example, 802.11ac or 802.11axThis is the current standard your adapter operates on. It's important to understand that this is the result of a handshake between your adapter and the router.

You can also use the graphical interface. Go to Settings → Network & Internet → Wi-Fi → PropertiesScroll down to the "Properties" section. This may list the adapter model and sometimes the connection type, although the command line provides a more accurate and immediate result.

If you see 802.11n On a modern laptop, check your network card drivers. Outdated software may prevent the adapter from using new protocols, even if the hardware supports them. Updating the drivers from the manufacturer's website often solves the problem.

Analyzing the router's web interface settings

The most reliable way to find out what mode your network is operating in is to look into the router's "brains." To do this, log into the device's web interface. In the browser's address bar, enter the gateway IP address (often 192.168.0.1 or 192.168.1.1) and enter your login/password.

In the settings menu, look for the "Wireless," "Wi-Fi," or "WLAN" sections. There you'll find the Mode settings. You might see options like 802.11 b/g/n mixed or 802.11 a/n/ac/ax mixed"Mixed" mode means the router automatically adjusts to the client's capabilities, which is convenient but not always optimal for speed.

In some advanced firmwares, for example, Keenetic, MikroTik or Asus With Merlin firmware, there is a "Client List" or "Monitoring" section. It displays the current connection standard for each connected device in real time (e.g., 11ac or 11n) and link speed.

• 🌐 Access your router settings via your browser.
• 📡 Go to the Wireless or Wi-Fi settings section.
• 🔍 Find the "Mode" parameter or the list of clients.
• ⚙️ If necessary, change the mode to "802.11ac/ax only" to force acceleration.

⚠️ Attention: If you force your router to use "802.11ax only" (Wi-Fi 6) mode, any older devices that don't support this standard will stop seeing and connecting to the network. Be careful when changing compatibility settings.

What is channel width and how does it affect the standard?

Channel width (20, 40, 80, 160 MHz) is the "road" through which data travels. The 802.11n standard typically operates at 20 or 40 MHz, 802.11ac requires 80 MHz, and 802.11ax can use 160 MHz. If the router is set to a narrow channel width, speed will be low even with the new standard.

The influence of frequency range on connection speed

Wi-Fi standards cannot be considered in isolation from frequency bands. Historically, the standard 802.11n can operate in both the 2.4 GHz and 5 GHz bands. However, the standards 802.11ac And 802.11ax (in the majority of implementations) are designed for the 5 GHz range and above.

The 2.4 GHz band is very noisy: microwaves, Bluetooth headsets, and neighbors' routers operate there. Even if your phone supports Wi-Fi 6, but is connected to a 2.4 GHz network, it will most likely be using the protocol. 802.11n or 802.11gwithout realizing its full potential. For high speeds, always choose a 5 GHz network.

Modern routers often use technology Band Steering, combining the 2.4 and 5 GHz network names into one. The router itself decides where to connect the device. Sometimes this decision can be wrong, and a powerful laptop becomes stuck on the slow 2.4 GHz band. In such cases, experienced users separate the networks by giving them different names (SSIDs), for example, HomeWiFi And HomeWiFi_5G.

Frequently Asked Questions (FAQ)

Why does my router say AC1200 but the speed is low?

The AC1200 rating represents the combined theoretical speed of all antennas and bands. Actual speed depends on the client standard, interference, distance, and channel width settings. Over-the-air speeds are also reduced by approximately 2-3 times the advertised speed.

Is it possible to upgrade an old router to Wi-Fi 6 using software?

No. Standards support 802.11ax Wi-Fi 6 requires the appropriate radio module and antennas inside the device. A software update cannot add hardware. If the router is old, it will need to be replaced.

What is the difference between Wi-Fi 6 and Wi-Fi 6E?

Technically, their data transmission protocols are identical. The difference is that Wi-Fi 6E adds support for the new, open 6 GHz frequency band. This helps avoid interference from neighboring networks, which is currently virtually nonexistent in the 6 GHz band.

How can I make my phone work faster if it is connected via 802.11n?

Try moving closer to the router, disabling Bluetooth on your phone (it interferes with the 2.4 GHz band), or switching to a 5 GHz network. If this doesn't help, the phone or router adapter may be physically limited to the older standard.
