The transition to a new wireless communication standard has become not just a marketing ploy, but a technical necessity for owners of 4K and 8K content. Modern TVs with Wi-Fi 6 support Provide a stable data stream even in noisy environments, where older devices lose packets and reduce image quality. This is especially important for those who are used to watching high-definition movies without annoying buffering.
The technology, also known as 802.11ax, fundamentally changes the approach to traffic distribution in a smart home. While the router previously polled each device in turn, creating queues, it now uses an OFDMA mechanism, allowing data to be transmitted to multiple devices simultaneously. Smart TV In this combination, it is one of the most demanding consumers, especially when streaming heavy video.
Owners of the latest models from leading brands can already appreciate the benefits of increased throughput. However, it's important to understand that this feature requires two conditions: a corresponding module in the TV and a router that supports the 802.11ax standard. Without both, the system will automatically switch to the older protocol.
Technical advantages of the 802.11ax standard for Smart TVs
The main advantage of switching to Wi-Fi 6 It's not so much peak speed as multitasking efficiency. The TV no longer conflicts with smartphones, laptops, and smart speakers, occupying its own niche in the broadcasting landscape. This is achieved through Target Wake Time technology, which allows the TV module to "sleep" when idle, saving energy and preventing unnecessary network noise.
Wide-channel performance has been significantly improved. While older standards often struggled on 80 MHz channels in apartment buildings, the new protocol operates reliably on 160 MHz channels. This provides a significant speed boost, essential for viewing high-definition content. 8K or for cloud gaming, where latency must be minimal.
It's also worth noting the improved 1024-QAM modulation. It allows for more data to be encoded in a single radio signal. For the user, this means: Smart TV It will be able to load heavy applications or buffer high-bitrate videos faster than previous-generation devices, even at the same distance from the router.
However, physical limitations should be considered. 5 GHz and 6 GHz signals penetrate walls less effectively than 2.4 GHz. Therefore, placing the router and TV in the same room or across the same wall is optimal for maximum performance.
List of Samsung models with Wi-Fi 6 support
Samsung was one of the first to implement the new wireless standard in its premium lines. Starting in 2020, its flagship models received updated communication modules. In particular, the series QLED 8K (models Q900T and newer) and top-end QLED 4K (Q80, Q90, Q95 series) are fully compatible with 802.11ax routers.
In 2021 and 2022, support was extended to more affordable lines. Models of the series Neo QLED (QN90, QN85) and conventional Crystal UHD Some model years are also equipped with the necessary equipment. It's important to check the specific model, as equipment may vary by region.

To check compatibility of your model, you can go to the settings menu. The path usually looks like this: Settings β Support β About TVThe exact model is indicated there, which can be used to determine the year of manufacture and technical specifications.
β οΈ Please note: In some regions, 2020 models may have come with different Wi-Fi modules. It's best to check the exact specifications of your panel on the manufacturer's official website using the serial number.
Models from LG, Sony and other manufacturers
Samsung's competitors aren't lagging behind in the technology race either. LG has begun mass-producing Wi-Fi 6 in its OLED and NanoCell TVs, starting with its 2020 models. This has particularly affected its OLED CX, GX, C1, G1 and newer versions. These TVs are often used to connect to PCs and gaming consoles, where network speed is critical.
Sony has added support to its top-end Android TV and Google TV series. ZH8, XH90, X90J and newer ones Bravia XR Equipped with modules compatible with high-speed routers, this allows for smooth streaming of high-quality content directly from the internal memory or via DLNA.
Chinese brands such as TCL And Xiaomi, also began to equip their flagship models (series R Series, Mi TV Master) with modern modules. However, in the budget segment, the older Wi-Fi 5 (ac) standard is most common, which is worth considering when purchasing.
Below is a table for quick reference of the main lines:
| Brand | Series/Line | Year of release | Wi-Fi 6 support |
|---|---|---|---|
| Samsung | Q900T, Q950TS | 2020+ | Yes |
| LG | OLED CX, C1, G1 | 2020+ | Yes |

| Xiaomi | Mi TV Master | 2021+ | Yes |
Sometimes you need to manually switch to compatibility mode or select a specific channel.
How to check if your TV supports Wi-Fi 6
Documentation isn't always readily available, so the most reliable way is to check the technical specifications through the device's menu or specialized applications. In operating systems Tizen, webOS or Android TV Connection information is often hidden in deep menus.
For Android TV you can use the app WiFi Analyzer or similar utilities available in the Google Play Store. They will show not only the signal strength, but also the protocol standard you are currently connected to. If it displays 802.11ax, which means everything is working correctly.
βοΈ Connection check
Samsung TVs have a hidden service menu, but this is risky for inexperienced users. The easiest way is to look up the model in Settings β Support β About TV and check it online. If the specifications indicate a wireless network speed above 867 Mbps, it most likely uses a new-generation module.
Another indirect indicator can be the download speed of apps from the store. If heavy games or movies download instantly with a good router, that's a good sign. However, for an accurate diagnosis, it's better to use third-party software.
β οΈ Warning: Do not attempt to access the TV's Service Menu without accurate knowledge of the login codes. Changing settings in this menu may cause the device to malfunction.
Setting up your router for maximum speed
Even if yours The TV supports Wi-Fi 6Without properly configuring your router, you won't see any difference. The first step is to ensure that 802.11ax mode is enabled on your router. On some models, it's called "Wi-Fi 6 Mode" or simply needs to be enabled in the basic wireless network settings.
It is recommended to separate the 2.4 GHz and 5 GHz bands into different SSIDs (network names). Name them, for example, HomeWiFi And HomeWiFi_5GConnect your TV to a 5 GHz network, as the older range physically cannot provide the speeds claimed for the new standard.
Approximate settings for ideal operation:Channel Width: 80 MHz or 160 MHz
Security: WPA3-Personal (or WPA2/WPA3 Mixed)
Band: 5 GHz only for TV
Security is also worth considering. The new standard recommends using an encryption protocol. WPA3If your TV supports it, be sure to enable this feature in your router. This will protect your home network from modern hacking methods.
What should I do if my TV can't see the 5 GHz network?
Make sure the region is set correctly in your router settings (some 5 GHz channels are prohibited in some countries). Try manually setting channel 36, 40, 44, or 48.>:Make sure the region is set correctly in your router settings (some 5 GHz channels are prohibited in some countries).

Compatibility issues and their solutions
Users often encounter a situation where, after purchasing a new router, their TV loses network connectivity or becomes unstable. This is because older Wi-Fi modules may not work properly with new modulation methods or the 160 MHz channel width.
The first thing you need to do is update your TV's firmware. Manufacturers regularly release patches that improve compatibility with network equipment. The update path is usually found in the menu: Settings β Support β Software Update β Update Now.
- π Reset your TV's network settings to factory settings.
- π Try disabling the "Smart Connect" function on your router, which combines frequencies.
- π Change the broadcast channel to a fixed one, avoiding automatic selection.
If the problem persists, it's possible the router's drivers are the issue. Check the router manufacturer's website for firmware updates. Sometimes a simple hardware restart helps: turn off the router, wait 30 seconds, turn it on, wait for it to load, then turn on the TV.
The Impact of Wi-Fi 6 on Streaming and Gaming
For gamers who use cloud services like Xbox Cloud Gaming or GeForce Now directly on their TV, the transition to Wi-Fi 6 has been a real lifesaver. Reducing ping (latency) and jitter (lag) makes games responsive. The image no longer breaks down into artifacts during sudden camera movements.
Streaming services like Netflix, Disney+, and Amazon Prime Video also benefit from stability. The TV can buffer content faster, allowing you to instantly rewind without waiting for frames to load. This is especially noticeable when watching in 4K HDR, where the video stream has a very high bitrate.
However, it's important to understand that your internet provider must provide sufficient speed. If your plan limits speed to 50 Mbps, no amount of Wi-Fi 6 will make 8K video smooth, as the bottleneck will be the external link, not the internal network.
In conclusion, upgrading to new technology is worthwhile for those with modern equipment and fast internet. It's an investment in comfort that pays off with lag-free viewing and high image quality.
Do I need Wi-Fi 6 if I have a 100 Mbps plan?
Yes, even at 100 Mbps, the new standard will provide a more stable connection, lower latency, and allow other devices in the house to work without lag while you watch a movie.
Does Wi-Fi 6 work on 2.4GHz?
Technically, the 802.11ax standard supports operation in the 2.4 GHz band, but the speed gain there is minimal. The main benefits are realized at 5 GHz and above.
Will Wi-Fi 6 speed up my old router?
No. For the technology to work, both devices are required: the router and the receiver (TV) must support the 802.11ax standard. If the router is older, the TV will switch to its mode.
Is it possible to install a Wi-Fi 6 module in an old TV?
External USB Wi-Fi 6 adapters generally don't work with TV operating systems (Tizen, WebOS) because they require specific drivers that TV manufacturers don't install. The built-in module cannot be replaced.
