Page loading speed and video connection stability directly depend on the wireless standard your equipment uses. Many users confuse the frequency range (2.4 or 5 GHz) with the actual protocol generation (standard). IEEE 802.11Understanding this difference is critical for setting up a home network and choosing a new router.
In this article, we'll explore all the ways to accurately determine the standard your router and smartphone operate on. You'll learn how to read the markings on the device, analyze Windows and Android system parameters, and understand why your fast internet plan may not be delivering its full potential due to outdated hardware.
Modern devices often support multiple standards simultaneously, switching between them depending on conditions. To avoid guessing why speed fluctuations occur, it's important to know the technical specifications of your devices. We'll cover methods ranging from a simple visual check to using specialized utilities.
Main standards and their characteristics
The history of wireless network development spans over two decades. Each new generation has brought not only increased speed but also new signal modulation technologies. Wi-Fi generation — this is a conventional designation that is now often linked to the standard number (Wi-Fi 4, 5, 6), which makes it easier for the average user to understand the evolution of technology.
Early standards, such as 802.11b and 802.11g, operated exclusively in the 2.4 GHz band and provided speeds of up to 54 Mbps. Today, they are almost completely decommissioned, although some older devices may still attempt to connect to them. The real breakthrough was the standard 802.11n, which pioneered MIMO technology and multi-antenna operation.
The modern market is dictated by standards 802.11ac (Wi-Fi 5) and 802.11ax (Wi-Fi 6). They operate primarily in the 5 GHz band, although they maintain backward compatibility. These protocols enable gigabit speeds over the air and ensure stable, lag-free operation of a smart home.
⚠️ Attention: The router box may be marked with the abbreviation "Dual Band." This means it supports two frequency bands, but it doesn't guarantee the latest Wi-Fi 6 standard. Always check the specific model specification (ac or ax).
Below is a table to help you quickly understand the generations and their theoretical capabilities. Please note that actual speeds are always lower than stated due to protocol overhead and interference.
| Generation | Standard | Year of release | Range | Max. speed |
|---|---|---|---|---|
| Wi-Fi 4 | 802.11n | 2009 | 2.4 / 5 GHz | 600 Mbps |
| Wi-Fi 5 | 802.11ac | 2013 | 5 GHz | 6.9 Gbps |
| Wi-Fi 6 | 802.11ax | 2019 | 2.4 / 5 / 6 GHz | 9.6 Gbps |
| Wi-Fi 6E | 802.11ax | 2020 | 6 GHz | 9.6 Gbps |
How to find out your Wi-Fi version on Windows
The Windows operating system provides built-in tools for diagnosing network connections. The fastest way to obtain information is using the command line. This is a universal method that works on all OS versions, from Windows 7 to Windows 11.
You need to launch the terminal with administrator or standard user rights. Enter the command netsh wlan show drivers and press Enter. In the list that appears, find the line "Radio types supported." This is where the maximum standard your Wi-Fi adapter can support is listed.
netsh wlan show driversIf you see in the list 802.11ac or 802.11ax, then your adapter supports high-speed standards. However, it's important to remember: if your router is older, your computer will switch to a lower standard for compatibility. You can also check the connection status through the graphical interface.
Go to Settings → Network & Internet → Wi-Fi → Hardware PropertiesIn the Properties section, there will be a line called "Protocol". It may say Wi-Fi 5 (802.11ac) or Wi-Fi 4 (802.11n)This shows what standard you are currently using with your current router.
☑️Checking the adapter in Windows
⚠️ Attention: Network card drivers may limit functionality. If your adapter physically supports Wi-Fi 6, but the system only displays Wi-Fi 5, try updating the drivers from the laptop or motherboard manufacturer's website.
Defining the standard on Android and iOS
In mobile operating systems, information is often hidden from the user's view, but there are ways to obtain it. On devices Android The situation depends on the UI manufacturer. On stock Android (Pixel, Motorola) and some ROMs (Xiaomi MIUI), you can see the connection type in the settings.
Go to Settings → About phone → General information (the path may vary). Look for the "Connection Speed" or "Connection Type" option. If it says VHT80 or HE80/HE160, you're using modern standards. VHT corresponds to Wi-Fi 5, and HE corresponds to Wi-Fi 6.
For users iPhone You're less fortunate: iOS hides technical information about the connection. The only reliable way is to look at the device model. All iPhones, starting with the model iPhone 11, support Wi-Fi 6. Older models (iPhone X and below) are limited to Wi-Fi 5 (802.11ac).
For detailed diagnostics on Android, you can use third-party utilities, for example, WiFi Analyzer or WiFi ManThese apps show not only the current standard, but also the signal strength, channel load, and interference from neighboring routers.
Why can't I see 5 GHz on my phone?
If your smartphone only supports 2.4 GHz, it won't physically detect 5 GHz networks. This is typical for budget models and devices released before 2015. Check the model specifications on the manufacturer's official website.
Visual identification of the router
The easiest way to identify your Wi-Fi generation is to look at the sticker on the bottom of your router or in the box. Manufacturers typically list key specifications in large print. Look for logos. Wi-Fi 5 or Wi-Fi 6, as well as inscriptions AC1200, AX3000 and the like.
The letter designation in the model name or specifications says a lot:
- 📡 N — indicates the 802.11n (Wi-Fi 4) standard. These routers typically offer speeds of up to 300 or 450 Mbps.
- 🚀 AC — marking of the 802.11ac (Wi-Fi 5) standard. The numbers after AC (e.g., 1200) indicate the combined speed in both bands.
- ⚡ AX — the latest 802.11ax (Wi-Fi 6) standard. Guarantees compatibility with multiple devices without sacrificing speed.
Also, pay attention to the number of antennas. While the number of antennas doesn't always directly correlate with the standard, Wi-Fi 6 routers often have a more complex design with multiple external antennas or hidden MIMO modules. Older models of the series TL-WR from TP-Link or DIR from D-Link without the AC prefix are most often referred to as Wi-Fi 4.
⚠️ Attention: Just because a router has a Gigabit Ethernet port (1000 Mbps) doesn't mean its Wi-Fi is fast. There are models with Gigabit ports, but they only support the older 802.11n standard. Always check the wireless specifications.
Using third-party software for analysis
If the built-in OS tools don't provide a complete picture, specialized programs can help. For Windows, an excellent choice is the utility WiFiInfoView from NirSoft or Acrylic Wi-Fi HomeThey provide detailed information about each available network.
In the interface of such programs, look for the column PHY Type or Standard. The current connection will be indicated there. For example, if you see 11ac, which means the Wi-Fi 5 standard is in effect. The programs also display the channel width (20, 40, 80, or 160 MHz), which directly affects speed.
For macOS, users can use a hidden diagnostic feature. Hold down the key Option and click the Wi-Fi icon in the top menu bar. An expanded menu will appear, with the standard listed in the "Mode" line, for example, 802.11ac.
Cross-platform solutions allow for network-wide auditing. This is especially useful in offices, where it's important to ensure that critical devices aren't falling back to older, slower standards due to interference or improper router configuration.
Frequently asked questions and compatibility issues
Even knowing how to check the Wi-Fi generation, users still encounter some nuances. A common question is: why is my router Wi-Fi 6, but my phone is slow? The answer lies in compatibility. The network always operates at the standard of the weakest device in the chain unless separate guest networks are configured.
Another issue is "guest" modes. Some routers, when enabling guest access, force the network to switch to compatibility mode (Wi-Fi 4) so that older guest phones can connect. Check your router settings and disable these modes. Legacy or b/g/n mixed, if you don't need support for ancient gadgets.
It's also worth mentioning the impact of distance. 5 GHz standards (Wi-Fi 5/6) have a shorter range and penetrate walls less effectively than 2.4 GHz. If you move far away from the router, the device may automatically switch to the longer-range but slower 802.11n standard.
Does Wi-Fi generation affect ping in games?
Yes, directly. Wi-Fi 6 (802.11ax) implements OFDMA technology, which allows for more efficient transmission of small data packets, which is critical for online gaming. This reduces jitter and latency compared to Wi-Fi 5 and especially Wi-Fi 4.
Do I need to change my router if I have a 100 Mbps tariff?
Technically, even the older Wi-Fi 4 (802.11n) can deliver 100 Mbps under ideal conditions. However, in practice, interference and loss will make the actual speed lower. For a stable 100 Mbps over the air, Wi-Fi 5 (802.11ac) is a minimum requirement.
Can Wi-Fi 6 work with older phones?
Yes, the standards are fully backwards compatible. A Wi-Fi 6 router will work with a Wi-Fi 4 phone; the connection will simply be established using the 802.11n protocol. You won't lose network access, but you won't get the benefits of the new speeds.
In summary, knowing your Wi-Fi generation is the first step to a fast and stable network. Don't be afraid to experiment with frequency and standard settings in your router's control panel to find the optimal balance for your home.
