Page loading speeds, video connection stability, and gaming ping times directly depend on the wireless protocol your equipment uses. Many users use routers for years without realizing that their devices support much higher speeds than they actually experience. Often, the problem lies in the settings or incompatible standards between the receiver and transmitter.
Understanding the difference between Wi-Fi 5 And Wi-Fi 6 This allows you to not only select the right router but also properly configure your existing network for maximum performance. In this article, we'll cover technical nuances, software verification methods, and visual differences that will help you identify your current configuration.
Determining your protocol is the first step to optimizing your home network. It only takes a few minutes but significantly improves connection stability. Let's explore the different wireless network generations and how to differentiate them.
The Evolution of Wireless Standards: From 802.11n to Wi-Fi 7
The history of Wi-Fi technology development is a constant race for throughput and latency reduction. The classification is based on the IEEE 802.11 specifications, which are periodically updated. The first widespread standard was 802.11n, also known as Wi-Fi 4It brought support for the 5 GHz band and MIMO technology, which allows for the transmission of multiple data streams simultaneously.
The next stage was the emergence 802.11ac or Wi-Fi 5This standard operates exclusively in the 5 GHz band and provides theoretical speeds of up to 6.9 Gbps. Most modern mid-range routers are based on this protocol. It handles multi-stream traffic, such as 4K streaming, much more efficiently.
The latest widespread generation is 802.11ax, the commercial name of which is Wi-Fi 6 and its improved version Wi-Fi 6EThe key difference lies in the device's operating efficiency: the new OFDMA algorithm allows for channel division into subchannels, reducing interference from neighboring networks.
⚠️ Please note: The "Wi-Fi 6E" label indicates support for the additional 6 GHz band, which is not yet available in all countries and requires a compatible client device.
Visual identification and marking of equipment
The fastest way to find out which standard is supported is to check the labels on the router body or the device's box. Manufacturers are required to clearly display key specifications. Typically, this information is located on the bottom panel along with the login information or on the side.
Pay attention to logos and abbreviations. If you see the inscription AC1200, AC1750 or simply AC, we are talking about the standard Wi-Fi 5The numbers after the letters AC indicate the total theoretical speed in megabits per second. Newer models are typically marked AX3000, AX6000 or logo Wi-Fi 6.
The number of antennas and their type also play an important role. Although the number of antennas does not guarantee a standard, devices that support MIMO 4x4 or 8x8 more often refer to older models of standards ac And axOld standard routers n often have one or two antennas and markings N300 or N450.
How to find out the Wi-Fi standard on a Windows computer
The Windows operating system provides built-in tools for diagnosing your network adapter. The easiest way is to use the command line. Open the terminal by entering cmd in the search and run the command to get a detailed report on the status of the wireless network.
netsh wlan show interfacesIn the list that appears, find the line "Radio protocol" (Radio type) or "Type". This is where the current connection standard will be indicated, for example, 802.11ax, 802.11ac or 802.11nIt's important to understand that this displays the standard the connection is currently operating at, not the maximum possible for the adapter.
An alternative method is via the Device Manager. Click Win + X and select "Device Manager." Find the "Network Adapters" section, right-click on your wireless module and select "Properties." Go to the "Advanced" tab. In the list of options, you can often find the item Wireless Mode or 802.11n/ac/ax Mode, where the supported mode will be indicated.
It is worth noting that if your router supports Wi-Fi 6, but the laptop was released 5 years ago, in the protocol line you will see 802.11ac. Communication is always established using the lowest common denominator of the capabilities of both devices.
Checking the Wi-Fi version on Android and iPhone smartphones
In mobile operating systems, information about the communication standard is often hidden in deep menus or requires the use of third-party utilities. On devices Android The situation depends on the manufacturer's shell. On "pure" Android (Pixel, Motorola), you need to go to Settings → Connections → Wi-Fi, click on the gear next to the active network and find the "Security Protocol" or "Standard" field.
However, the most reliable way on Android is to use specialized applications such as WiFi Analyzer or WiFi ManThey show not only the current standard, but also the channel width, signal strength, and airtime load. This helps us understand why speeds may be lower than expected.
To the owners iPhone And iPad Less fortunate: iOS doesn't provide native access to the technical details of the connection for regular users. You can only find out the standard indirectly by looking at the device model in Settings → General → AboutIf you have an iPhone 11 or newer, it definitely supports Wi-Fi 6Models 6 through 10 operate on Wi-Fi 5.
⚠️ Note: Settings interfaces may vary depending on the firmware version and smartphone brand. If you can't find the option you need, use third-party analyzer apps.
Comparative table of characteristics of standards
To make technical information easier to understand, we've compiled the main parameters of popular standards into a single table. This will help you quickly understand the capabilities of your equipment.
| Standard | Commercial name | Year of release | Max. speed | Frequencies |
|---|---|---|---|---|
| 802.11n | Wi-Fi 4 | 2009 | 600 Mbps | 2.4 GHz, 5 GHz |
| 802.11ac | Wi-Fi 5 | 2014 | 6.9 Gbps | 5 GHz |
| 802.11ax | Wi-Fi 6 | 2019 | 9.6 Gbps | 2.4 GHz, 5 GHz |
| 802.11be | Wi-Fi 7 | 2026 | 46 Gbps | 2.4, 5, 6 GHz |
As can be seen from the table, the evolution is moving towards increasing not only the peak speed, but also the efficiency of spectrum use. The transition from Wi-Fi 4 on Wi-Fi 5 gave a multiple increase in speed, while Wi-Fi 6 focuses on stability with a large number of connected gadgets.
Impact of the standard on real speed and stability
Many users confuse the speed of their internet provider's connection with the speed of their local wireless network. The Wi-Fi standard determines the bandwidth between your device and the router. If you have a 100 Mbps plan but an older router (802.11n), you may not notice a difference. However, with plans of 300 Mbps and above, the wireless module will become the bottleneck.
In addition to speed, the new standards offer improved latency management (Latency). In games and video calls, it's critical not only how much data is transferred, but also how quickly it arrives. Protocol 802.11ax implements technology TWT (Target Wake Time), which allows devices to "negotiate" the timing of data transmission, saving smartphone batteries and reducing competition for airtime.
Channel width is also worth mentioning. Older standards often operate at 20 MHz. Wi-Fi 5 And Wi-Fi 6 They use 80 MHz and even 160 MHz channels. This is like widening a one-lane road into a four-lane highway. However, in apartment buildings, wide channels can create more interference if they are configured incorrectly.
Why is the Wi-Fi speed always lower than what is stated on the box?
Actual speed is always lower than theoretical due to protocol overhead, distance loss, walls, and interference from household appliances. Typically, the actual speed is 50-70% of the standard's maximum.
Configuring your router to operate in optimal mode
Once you've determined the standard of your equipment, you need to make sure the router is configured correctly. It often happens that a powerful router Wi-Fi 6 It operates in compatibility mode with older devices, artificially reducing the speed for all clients. Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1).
Find the wireless settings section (Wireless Settings). There should be a parameter "Operating mode" (Mode). Make sure the mode is selected 802.11 ax/ac/n mixed or similar, supporting the latest standards. If it's only worth 802.11n, switch to the desired mode or ax.
☑️ Wi-Fi Optimization Checklist
Pay special attention to the separation of ranges. It is recommended to create two separate networks with different names (SSIDs), for example, MyHome_2.4 And MyHome_5GConnect TVs, consoles, and laptops to the 5 GHz frequency, while leave the 2.4 GHz frequency for smart light bulbs and vacuum cleaners, which prioritize range over speed.
⚠️ Please note: Router manufacturers regularly update firmware, changing the interface and menu layout. If you can't find a setting, consult the official manual for your specific model.
Frequently Asked Questions (FAQ)
How do I know if my laptop supports Wi-Fi 6 if it doesn't explicitly show up in Device Manager?
Check the exact model of your network adapter in the Device Manager or via the command dxdiag. Enter the model name in the search engine. If the specifications indicate support for the standard 802.11ax, which means the hardware is ready. Wi-Fi 6 has also begun to be widely implemented in laptops with 10th-generation Intel processors and newer.
Will a Wi-Fi 6 router work with an old phone?
Yes, Wi-Fi standards are fully backward compatible. Your old phone will connect to the new router, but will operate at its maximum speed (for example, according to the standard). 802.11ac or n). The only benefits you'll get from a new router are better signal reception and lower latency.
What is the difference between Wi-Fi 6 and Wi-Fi 6E?
Technically it's the same standard. 802.11axThe "E" prefix (Extended) signifies the addition of access to the new 6 GHz frequency band. This provides more available channels, but requires both the router and the receiving device to support this band.
Do I need to change the cable in the wall if I bought a Wi-Fi 6 router?
Check the cable label. For speeds above 100 Mbps, a category 1 cable is required. Cat5e or Cat6If you have an old cable installed Cat5 (4 wires), it will cut the speed to 100 Mbps, regardless of the power of the router.
