Modern Smart TV It's impossible to imagine a life without a stable, high-speed internet connection. If you plan to watch 4K content, play cloud games, or stream from your phone, the standard 2.4 GHz band may not be enough. This is where 5 GHz-enabled TVs, providing high data transfer rates and minimal delays.
However, not all devices released in recent years are compatible with this frequency range. Manufacturers often skimp on wireless modules in budget models, opting for only outdated standards. In this article, we'll explore how to determine your screen's compatibility with modern networks and which brands guarantee high-frequency operation.
Understanding technical specifications when buying new equipment can be difficult, especially when the specifications in stores are written in fine print. We've prepared a detailed guide to help you avoid mistakes and choose a truly fast one. Smart TV.
Technological standards and range differences
Understanding the difference between 2.4 GHz and 5 GHz frequencies is critical to enjoying multimedia features. The range 2.4 GHz is older, it has a longer range, but low throughput and high congestion from neighboring routers and household appliances. At the same time, 5 GHz Provides speeds up to 1300 Mbps and higher, which is ideal for high-definition video streaming.
The technology that combines these two ranges is called Dual-BandTelevisions with this module can switch between frequencies automatically or by user selection. This allows the device to select the least noisy channel for data transmission, ensuring a stable connection even in apartment buildings with dozens of neighboring networks.
It's worth noting that 5 GHz support often comes in pairs with standards Wi-Fi 5 (ac) And Wi-Fi 6 (ax)Older models may only support Wi-Fi 4 (n), which theoretically can operate at 5 GHz, but in practice is rare in TVs and is limited in speed.
List of brands and series with 5 GHz support
Almost all flagship and mid-range models from leading manufacturers are equipped with dual-band modules. However, in the budget segment (especially in series up to 32 inches), a limited version of Wi-Fi is often found. Below is an overview of the main brands.
Samsung introduces 5 GHz support to all TVs starting from the series NU7000 and newer (series 7, 8, 9, and QLED). Budget series 4 and 5 may have limitations depending on the year of manufacture and screen size. For precise model identification, it's best to refer to the specific part number specifications.
Company LG also adheres to the policy of installing Dual-Band modules in TVs with 4K resolution. Models of the series UN7300, NanoCell 80/85/90 The OLED and OLED series are guaranteed to operate at 5 GHz. For HD models, the situation is similar to Samsung's—specific model testing is required.
- 📺 Sony: All Android TV and Google TV models from 2018 (X80 series and above).
- 📺 Xiaomi / Mi: Almost all Mi TV Stick, Box and TV models have Android TV on board.
- 📺 Philips: Performance and Ambilight series released after 2019.
It's important to note that even within a single series, there may be exceptions for different delivery regions. European models often feature more advanced communication modules than some localized versions for developing markets.
How to check for 5 GHz support in your TV settings
If you already have a TV at home, there's no need to delve into the technical documentation. The easiest way to check the module's capabilities is to try to find a 5 GHz network in the list of available connections. Your router must be configured accordingly.
Go to the network settings menu. The path usually looks like this: Settings → Network → Open network settings → WirelessIf your router is broadcasting a 5 GHz network and it's not hidden, it should appear in the list. If you only see one network (or two with the same name, but one isn't selectable), your TV module may not support the higher frequency.
⚠️ Note: If the 2.4 GHz and 5 GHz network names on your router are the same (Smart Connect technology), the TV may automatically switch between them. To verify this, it's best to temporarily separate the network names (SSIDs) in your router settings.
☑️ Check TV compatibility
Comparison of Wi-Fi module specifications in TVs
For a visual comparison of the capabilities of different generations of wireless modules used in Smart TVs, please refer to the table. It will help you understand what to expect from your device depending on the year of manufacture and the stated specifications.
| Wi-Fi standard | Frequency range | Max. speed (theoret.) | Examples of TV series |
|---|---|---|---|
| Wi-Fi 4 (802.11n) | 2.4 GHz / 5 GHz | up to 600 Mbps | Old Smart TVs (2013-2016) |
| Wi-Fi 5 (802.11ac) | 5 GHz | up to 3.5 Gbps | Most 4K TVs (2017-2021) |
| Wi-Fi 6 (802.11ax) | 2.4 GHz / 5 GHz | up to 9.6 Gbps | Flagships 2022+ (Samsung Neo QLED, LG OLED) |
| Wi-Fi 6E | 2.4 / 5 / 6 GHz | up to 30 Gbit/s | Top models 2026+ |
As can be seen from the table, even the standard Wi-Fi 4 Theoretically, it supports 5 GHz, but in the reality of TVs of that time, this was rarely implemented. Real speed and stability gains begin with the implementation of the standard. 802.11ac.
Connection problems and their solutions
Even with compatible equipment, users may encounter difficulties. Often, the problem lies not with the TV, but with the router settings. For example, if the router has WPA3 security and the TV is older, it may simply not see the network, even though it physically supports the frequency.
Another common issue is automatic channel selection by the router. Some TVs perform poorly on certain channels in the 5 GHz band (for example, DFS channels used by radar). In this case, manually setting the channel in the router settings to 36, 40, 44, or 48 can help.
⚠️ Important: Make sure the region in your router settings matches the region your TV is configured for. Mismatched regions can cause certain frequency ranges to be blocked at the driver level.
What should I do if the TV sees the network but doesn't connect?
Try changing the encryption type on your router from WPA3 to WPA2-PSK (AES). Also, check if MAC address filtering is enabled in the router's security settings. In rare cases, entering a static IP address in the TV's network settings may help.
Alternative ways to get high speed
If your TV doesn't support 5 GHz but you still want to watch high-quality content, don't rush to buy a new device. There are several proven ways to bypass this limitation and get a stable internet connection.
The most reliable option is a cable connection. LANIf the router is nearby, a twisted pair cable will provide faster speeds than any Wi-Fi and provide complete stability without interference. Modern TVs are equipped with Fast Ethernet (100 Mbps) or Gigabit Ethernet (1000 Mbps) ports.
The second option is to use external adapters. Some Samsung and LG models support proprietary Wi-Fi adapters that connect via USB. However, these are currently difficult to find and often require custom configuration.
- 🔌 TV box: Buy a set-top box (Android Box, Apple TV) with a modern Wi-Fi module. It connects via HDMI, and the TV is used only as a display.
- 🔌 Powerline adapters: Internet transmission via electrical wiring. One adapter is connected to the router's outlet, and the other to the TV's outlet.
- 🔌 Smartphone as a modem: Sharing the Internet from your phone via a USB cable (requires USB Tethering support on your TV).
Is it possible to flash a TV to support 5 GHz?
No, frequency support is determined by the hardware (the Wi-Fi chip). Firmware can't add a physical module that isn't on the board.
FAQ: Frequently Asked Questions
Does screen size affect 5GHz Wi-Fi support?
There's no direct correlation, but an indirect one can be observed. Manufacturers are less likely to equip small TVs (up to 32 inches) with dual-band modules, as they are often in the budget segment. Larger screens are more likely to be 4K and require high internet speeds.
Do I need a special router to use 5 GHz on my TV?
Yes, your router must support the Dual-Band standard. If your router is older and only operates on 2.4 GHz, your TV, even if it supports 5 GHz, won't be able to use that frequency because the signal source isn't broadcasting it.
Why is the 5GHz Wi-Fi speed lower than stated in the specifications?
Actual speed is always lower than theoretical due to signal loss, interference, distance to the router, and channel congestion. Furthermore, the TV's processor may limit the speed of processing network packets, especially when decoding video.
Can a firmware update add 5GHz support?
No. As mentioned, this is a hardware limitation. A software update can improve connection stability or fix bugs, but it won't add support for frequencies if the Wi-Fi chip doesn't physically support them.
