Have you noticed in recent years that a small number has started appearing next to the familiar wireless network icon on your smartphone or laptop screen? This isn't an interface error or a firmware glitch, but an indicator of a new generation of wireless technology. sixes indicates that your device is connected to a router that operates using the IEEE 802.11ax standard, which is commonly referred to as Wi-Fi 6 in marketing materials.
For a long time, we've become accustomed to acronyms like 802.11n or 802.11ac, which meant little to the average user. To make things easier, the Wi-Fi Alliance introduced a new numbering system, assigning each generation a sequential number. Number 6 means you're in range of modern equipment capable of providing higher speeds and a more stable connection, even with a large number of connected devices.
Understanding what this symbol means will help you properly configure your home network and select the right equipment. Unlike previous versions, this standard focuses less on peak speed per client and more on efficiently distributing resources across multiple devices. Let's explore the real benefits of switching to this new technology and whether upgrading your router is necessary.
Evolution of wireless communication standards
The history of wireless networking goes back several decades, and each advance has been marked by increased throughput. Early standards, such as 802.11b and 802.11g, delivered speeds that seem laughable today but were revolutionary back then. With the advent of 802.11n (Wi-Fi 4), we now have the 5 GHz band and MIMO technology, allowing for the transmission of multiple data streams simultaneously.
The next step was Wi-Fi 5 (802.11ac), which finally cemented the dominance of the 5 GHz band for high-speed tasks. However, with the growing number of smart devices in every home—from light bulbs to 4K TVs—even powerful routers began to struggle to handle the backlog of requests. This is where Wi-Fi 6, designed for high-density environments, comes in.
⚠️ Attention: The number 6 on your smartphone's screen doesn't guarantee high internet speed if your provider's data plan is limited. The communication standard only determines the connection speed between your device and the router, not the speed of your internet connection.
It's important to understand that backward compatibility is fully preserved. If you buy a new router with sixth-generation support, your older laptops and phones will continue to work; they just won't be able to take advantage of the protocol's new benefits. For full functionality, both the access point and the client device must support the standard.
Technical differences between Wi-Fi 6 and previous versions
The main technical innovation was the technology OFDMA (Orthogonal Frequency-Division Multiple Access). While previous standards allowed a router to transmit data to only one device at a time (albeit rapidly switching between them), OFDMA allows a single communication channel to be divided into multiple smaller subchannels. This is similar to the difference between sending a single truck with a single load and sending a train consisting of multiple cars carrying different loads simultaneously.
Another important improvement was the improvement of technology MU-MIMOIn the Wi-Fi 5 standard, a router could only transmit data to multiple devices simultaneously in the "router-to-client" (downlink) direction. The sixth generation added support for Uplink MU-MIMO, which allows devices to also send data to the router simultaneously without creating queues. This is critical for video calls and online gaming.
Let's compare the key characteristics of different generations in a table to see the progress clearly:
| Characteristic | Wi-Fi 5 (802.11ac) | Wi-Fi 6 (802.11ax) | Wi-Fi 6E |
|---|---|---|---|
| Maximum speed | up to 3.5 Gbps | up to 9.6 Gbps | up to 9.6 Gbps |
| Frequency ranges | 5 GHz | 2.4 GHz and 5 GHz | 2.4, 5 and 6 GHz |
| Access technology | OFDM | OFDMA | OFDMA |
| MU-MIMO | Downlink only | Uplink and Downlink | Uplink and Downlink |
Also worth mentioning is modulation. 1024-QAM, which replaced 256-QAM. This allows more data to be encoded in a single radio signal, theoretically increasing transmission speed by approximately 25%. However, this feature requires an exceptionally clean signal without significant interference or reflections.
How to check if your device supports the standard
Before you rejoice at the new number or rush out to the store for a new router, you need to verify the technical capabilities of your equipment. The number 6 will only appear on the screen if both the router and the receiving device (smartphone, laptop, or tablet) support the 802.11ax standard. If even one endpoint doesn't support this standard, the system will automatically switch to the older protocol.
You can check for support on a Windows computer using Device Manager. Find your wireless adapter in the list, open its properties, and go to the "Advanced" tab. In the list of parameters, you'll often see a line like "Wireless Mode" or "802.11ax Mode," which should be set to Enabled or 802.11ax.
List of popular chips with Wi-Fi 6 support
For smartphones, this means Qualcomm Snapdragon 865 and newer, MediaTek Dimensity 1000+. Laptops use Intel AX200, AX201, AX210 adapters, as well as MediaTek and Realtek RTL8852 series modules. If you have a device released before 2019, the likelihood of supporting this standard is extremely low.
Android and iOS smartphone owners have an easier time navigating. The number 6 appeared in the interface starting with Android 11 and iOS 14, respectively, but only if the hardware supports it. Flagship models from 2020 and newer are generally already equipped with the necessary modules. Budget devices may only receive support in newer models.
Configuring your router to work in Wi-Fi 6 mode
If you've purchased a modern router but the number 6 still doesn't appear, you may need to configure it manually. Many manufacturers enable the new standard by default, but in some cases, you'll need to activate it in the device's web interface. To do this, enter the router's IP address (usually 192.168.0.1 or 192.168.1.1) in the browser's address bar.
After logging in, find the section responsible for the wireless network. It may be called Wireless, Wi-Fi Settings or Wireless modeHere you need to find the parameter related to the operating mode or standard. Make sure that the mode selected for the 5 GHz band (this is where the new standard most often operates) 802.11ax or Wi-Fi 6, not mixed mode with older versions.
☑️ Router setup checklist
Also worth paying attention to is the function TWT (Target Wake Time). This allows devices to negotiate a wake-up time with the router to transfer data, significantly saving battery power on smartphones and smart devices. Enabling this option can be a separate setting in advanced routers.
Impact on connection speed and stability
Many users expect the transition to Wi-Fi 6 to instantly increase file download speeds by three to four times. The reality is that in a typical home environment with one or two active devices, the speed increase may be virtually imperceptible. The main advantage of the new standard is revealed in scenarios with high network load.
Imagine a situation where one family member is watching 4K video, another is playing an online shooter, a third is downloading large files, and a smart vacuum is updating the apartment map. In previous-generation networks, the router would be bogged down switching between clients, causing micro-delays (jitter) and image flickering. Wi-Fi 6 Thanks to OFDMA technology, it processes all these requests in parallel, making the network responsive for every device.
Furthermore, the new standard better copes with interference in apartment buildings. Color enhancement algorithms (BSS Coloring) allow the router to ignore signals from neighboring networks if they have a different "label," reducing interference and improving connection stability even in densely populated areas.
Frequently asked questions and compatibility issues
Despite the advantages, the implementation of the new standard is not without its challenges. Users often encounter situations where, after purchasing a new router, older devices stop seeing the network or become unstable. This may be due to encryption protocols being enabled by default in the security settings. WPA3, which is not supported by older gadgets.
In this case, it is recommended to use mixed security mode. WPA2/WPA3 Or temporarily switch to WPA2 until you upgrade your devices. It's also worth considering that a 160 MHz channel width is required for maximum speeds, but in noisy environments in an apartment building, the router may automatically reduce it to 80 MHz to ensure stability.
⚠️ Attention: The settings interfaces of routers from different manufacturers (Keenetic, TP-Link, ASUS, Xiaomi) can vary significantly. Menu item names and locations depend on the firmware version. Always consult the official manual for your specific model.
If you notice a drop in speed after enabling Wi-Fi 6, try disabling the 160 MHz feature or manually changing the channel to a less crowded one. Automatic channel selection algorithms don't always work perfectly in challenging conditions.
Is it necessary to buy a new router if the number 6 appears on the phone?
No, it's not necessary. The number only appears when the phone is connected to a router that supports this standard. If you have an older router, the number 6 won't appear, but your internet will still work as usual. Getting a new router makes sense if you have a lot of devices and are experiencing network slowdowns.
What is the difference between Wi-Fi 6 and 5G?
These are completely different technologies. Wi-Fi 6 is a wireless local area network standard (your home internet via a router). 5G is a fifth-generation mobile communications standard (internet via a carrier's SIM card). They don't compete, but rather complement each other.
Why does the number 6 disappear when I leave the house?
At home, you're connected to your Wi-Fi router. When you're outside or on public transport, your phone switches to your carrier's mobile network (4G/LTE/5G). The Wi-Fi icon disappears completely because you're no longer using the wireless network.
Will Wi-Fi 6 increase ping in online gaming?
Yes, it can potentially reduce ping and make it more stable, especially if other devices are actively using the network. TWT technology and improved packet queuing help prioritize gaming traffic, reducing latency.
