The speed and stability of a wireless connection directly depend on the data transmission standard used. Many users confuse the signal frequency with its protocol, although these are completely different technical parameters that affect network performance. Understanding what standard exactly Currently used by your device, it helps diagnose problems with low speed or internet drops.
There are several generations of wireless technologies, and each has its own bandwidth limitations. If your router supports a modern 802.11axIf your smartphone is connected using an older standard, you won't get the speed your provider claims. In this article, we'll cover all the ways to find out the current protocol on various operating systems and hardware.
Knowing your current connection type is also essential for setting up your home network for maximum performance. Devices often get stuck on outdated standards due to incorrect driver settings or the router itself. Let's figure out how to check this and, if necessary, fix it.
The main types of Wi-Fi protocols and their differences
Family of standards IEEE 802.11 is constantly evolving, offering ever-higher data transfer rates. The very first mass-market standard was 802.11b, which provided speeds of up to 11 Mbps, which is completely insufficient for modern tasks. It was followed by 802.11g, which raised the bar to 54 Mbps, but it, too, has long been considered obsolete.
The most widespread standard in recent years has been 802.11n, also known as Wi-Fi 4. It uses MIMO technology, which allows multiple antennas to transmit data simultaneously, significantly improving signal stability. However, the real breakthrough was 802.11ac (Wi-Fi 5), which operates primarily in the 5 GHz band and delivers gigabit speeds.
⚠️ Note: Outdated protocols (b/g) are not only slow but also offer poor data security. If your device connects via these protocols, we recommend updating your network adapter or router.
The latest standard to come out is 802.11ax, the commercial name of which is Wi-Fi 6It is optimized for use with a large number of connected devices, which is critical for a smart home. Below is a table comparing the key features of popular standards.
| Standard | Commercial name | Max. speed (theoret.) | Frequency range |
|---|---|---|---|
| 802.11n | Wi-Fi 4 | 600 Mbps | 2.4 GHz / 5 GHz |
| 802.11ac | Wi-Fi 5 | 6.9 Gbps | 5 GHz |
| 802.11ax | Wi-Fi 6 | 9.6 Gbps | 2.4 GHz / 5 GHz / 6 GHz |
| 802.11be | Wi-Fi 7 | 46 Gbps | 2.4 / 5 / 6 GHz |
Understanding these differences helps you choose the right equipment. For example, if your provider offers a 500 Mbps plan, but your router only supports 802.11n, you won't be able to utilize the full bandwidth.
Why is the speed lower than stated?
Real connection speeds are always lower than theoretical ones due to protocol overhead, interference in the air, and distance to the router. Actual speeds are typically 50-70% of the standard's maximum.
Checking the protocol on a Windows computer
The Windows operating system provides built-in tools for diagnosing network connections. The fastest way to determine your connection type is to use the command line or the graphical settings interface. This doesn't require installing any additional software and works on all versions of the system from 7 to 11.
To access information through the graphical interface, open the Network and Sharing Center. Right-click the Wi-Fi icon in the system tray and select "Network and Internet settings." Then, go to "Change adapter settings," find your wireless connection, right-click it, and select "Status."
- 📡 In the window that opens, find the "Speed" field - the standard is often indicated there (for example, 802.11ac).
- 💻 For more detailed information, click the "Details" button.
- 🔍 Look for the line “Radio Type” or “Protocol”, where the specific standard will be indicated.
- ⚙️ Alternatively, in PowerShell you can enter the command
netsh wlan show interfaces.
The command line often gives more accurate information, especially if the GUI only displays the speed in Mbps. Enter cmd in the search, run as administrator and enter the command netsh wlan show interfacesIn the output, find the line "Radio type".
☑️ Wi-Fi diagnostics on Windows
If the radio type line contains a value 802.11n If your router supports AC/AX or lower, the issue may be with the drivers. Update your network adapter software through Device Manager or the laptop manufacturer's website.
How to find out the Wi-Fi standard on Android and iOS
Mobile operating systems hide the technical details of the connection from the average user, but there are still ways to find out the protocol. On Android, the situation depends on the OS version and the manufacturer's shell (Samsung, Xiaomi, etc.).
On modern Android smartphones (version 10 and above), you can find this information in the "About phone" menu or in the detailed connection status. Go to Settings → Network & Internet → Wi-FiClick on the name of the connected network or the gear icon next to it. In some shells, for example MIUI or OneUI, under Speed or Signal Quality, you may see a standard (such as Wi-Fi 5 or Wi-Fi 6).
⚠️ Note: The settings interface may vary depending on your phone model. If the menu doesn't provide details, use third-party analyzer apps.
For iPhone owners, the situation is more complicated. iOS doesn't provide direct protocol information in the standard menu. The only reliable method is to use a utility. AirPort (for older Apple devices) or specialized developer apps that require a computer connection. However, you can indirectly determine the standard based on speed:
- 📱 If the speed is above 400 Mbps, it is most likely 802.11ac or ax.
- 📶 Connections in the 2.4 GHz band rarely exceed the 802.11n standard.
- 🔋 Energy saving may force iPhone to use a slower protocol.
For deep diagnostics on Android, you can use the app WiFi Analyzer or Fritz!App WLANThey show not only the current channel and frequency, but also the negotiated rate (connection speed), which can be used to accurately determine the protocol.
Diagnostics via the router's web interface
The most reliable source of information about how your network is working is the router itself. The router's web interface shows which devices are currently connected and which standards they use. This is especially useful when trying to figure out why a particular device is running slowly.
To enter the settings, enter the router's IP address in the browser's address bar (often 192.168.0.1 or 192.168.1.1). After entering your login and password, find the section that may be called “Status,” “Network Map,” “Client List,” or Wireless Statistics.
The list of connected clients (Connected Devices) typically displays the device name, its IP address, and connection type. Look for the "Standard," "Rate," or "Interface" column. This will indicate whether the device is operating in "Standard" mode. 802.11b/g/n or 802.11ac/ax.
You can also check your wireless settings here. Make sure "Auto" is selected in the "Wireless Settings" section or the default is forced. 802.11ac/axSometimes routers operate in mixed mode by default, which is not always optimal.
Impact of drivers and adapter settings
It often happens that both the router and computer support high speeds, but the connection is established using a low-level protocol. In 90% of cases, the culprit is outdated network adapter drivers or incorrect configuration within the system.
Check the adapter's properties in Windows Device Manager. Find your Wi-Fi module and go to "Properties" → "Advanced" tab. Here, look for parameters related to the operating mode. They may be called "Wireless Mode," "802.11n Mode," "VHT Mode," or "HE Mode."
- 🔧 Make sure the operating mode is set to "Auto" or "802.11ac/ax".
- 🚀 The "Throughput Booster" option sometimes helps, but can reduce stability.
- 📡 The "Roaming Aggressiveness" option affects switching between access points.
If modern standards aren't listed among the available modes, the driver is too old and doesn't support new hardware. Download the latest version from the laptop or chipset manufacturer's website (Intel, Realtek, Qualcomm).
⚠️ Warning: When updating drivers through Device Manager, Windows may report that "the best drivers are already installed." This is often false. Always download drivers from the hardware manufacturer's official website.
It's also worth paying attention to the channel width. 802.11ac and higher require a channel width of 80 MHz or 160 MHz. If the router or adapter is set to 20 MHz, high speeds will not be possible.
Frequently Asked Questions (FAQ)
Why does my router say Wi-Fi 6, but my phone connects via Wi-Fi 5?
This happens if your smartphone doesn't support the 802.11ax standard. The router automatically downgrades the standard to the highest supported by the client device. Also, check if Wi-Fi power saving mode is enabled on your phone.
Can the Wi-Fi protocol change on its own?
Yes, if you move around your apartment and the signal weakens, the router may switch the device to a more stable but slower protocol (for example, from AC to N). This also happens when the 5 GHz band is overloaded.
Does the protocol affect ping in games?
Absolutely. Newer protocols (ax/be) have lower latency and are better at managing data packet queues, which is critical for online gaming. The older 802.11n protocol can result in unstable ping even with high download speeds.
Do I need to change my router if I have a 100 Mbps tariff?
For 100 Mbps speed, the 802.11n standard is sufficient, but only under ideal conditions. For stability and power reserves, a router with 802.11ac support is better, as it penetrates walls better and is less susceptible to interference.
