Modern internet surfing and video streaming require high bandwidth, which the old 2.4 GHz band often cannot provide. This is why the question of Which devices support 5 GHz Wi-Fi?, becomes critically important when upgrading a home network. Switching to this frequency eliminates interference from microwave ovens and neighboring routers, ensuring a stable and fast connection.
However, not all equipment automatically gains access to high-speed wireless communication highways. Standards 802.11ac And 802.11ax Wireless networks have become widespread relatively recently, so you may have many gadgets in your home that are physically unable to "see" the new network. In this article, we'll cover equipment compatibility, testing methods, and setup details in detail.
Understanding how radio modules work will help you avoid buying unnecessary hardware and configure your router correctly. Devices released before 2013 in the vast majority of cases do not have a built-in 5 GHz module. Let's figure out how to determine the capabilities of your equipment without complex measuring instruments.
Technical differences between Wi-Fi bands and standards
The 5 GHz band isn't just "faster internet"; it's a fundamentally different radio signal physics. Unlike 2.4 GHz, which has only three non-overlapping channels, 5 GHz has significantly more, eliminating congestion in apartment buildings. To operate at this frequency, a network adapter must support the standards. 802.11a, 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6).
It's important to understand that 5 GHz support is often paired with MIMO (Multiple Input Multiple Output) technology, which uses multiple antennas to transmit data simultaneously. This significantly increases the actual connection speed, but requires the appropriate hardware. Older devices using the standard 802.11n can support 5 GHz, but only in single-threaded mode, which limits their maximum speed.
There's also the term "Dual Band," which means a device can operate on both 2.4 and 5 GHz, switching between them automatically or by user selection. This is the preferred option for modern technology, providing a balance between range and speed.
⚠️ Attention: The presence of a Wi-Fi logo on the case does not guarantee 5 GHz support. Be sure to check the model's specifications, looking for "5G," "Dual Band," or "802.11ac/ax" markings.
Smartphones and tablets: the evolution of frequency support
In the mobile world, the transition to high frequencies has happened quite quickly. Flagship iPhone models, such as iPhone 5 and newer already support the 802.11ac standard. In the Android camp, the situation was more mixed: high-end smartphones from Samsung (Galaxy S and Note series), Google Pixel And OnePlus switched to 5 GHz around 2014-2015.
The situation is more complicated in the budget segment. Up until 2018-2019, inexpensive smartphones and tablets from Chinese brands were often equipped with only 2.4 GHz modules to reduce costs. If your mobile device is inexpensive and was purchased several years ago, there's a high chance it won't detect the 5 GHz network, even if your router broadcasts it.
You can check for support through the settings. On Android, the path usually looks like this: Settings → About phone → All specs → Wi-FiIf the 802.11 a/b/g/n/ac standards are listed, then support is available. iOS doesn't provide such detailed information in the menu, so you have to rely on the device model and year of manufacture.
- 📱 Apple: Full support from all iPhone 5 and iPad (4th generation) devices and newer.
- 🤖 Android Flagships: Samsung Galaxy S4 and newer, Huawei P6 and newer, Xiaomi Mi 3 and newer.
- 💊 Tablets: iPad Air 1, Samsung Galaxy Tab S and newer models.
Why does iPhone sometimes not see 5 GHz?
Even if your iPhone supports 5 GHz, it may not connect to the network if your router is set to a region other than yours or to a channel higher than 64 (DFS channels), which mobile devices scan less frequently to save power.
Laptops and PCs: How to Test Your Network Adapter
The situation with computer equipment is the most confusing, as laptops have been assembled from various components for decades. Business-class laptops (series ThinkPad, Latitude, EliteBook) received 5 GHz support back in the days of Windows 7. However, mass-market consumer models could only be equipped with cheap Realtek or Atheros 2.4 GHz cards until 2016.
For desktop PCs, everything depends on the network card installed. If you're using the motherboard's integrated Wi-Fi, check the chipset model on the manufacturer's website. If you're using a USB dongle, only models labeled "AC" or "AX" support 5 GHz. Older 150 Mbps or 300 Mbps USB adapters operate exclusively in the 2.4 GHz band.
The most reliable way to check in Windows is to use the command line. Click Win + R, enter cmd and run the command:
netsh wlan show driversIn the list that opens, find the line “Supported radio types.” If it’s there, 802.11a, 802.11ac or 802.11ax, then the hardware is ready to work. Unless 802.11b/g/n, then to switch to 5 GHz you will need to replace the adapter.
☑️ Windows adapter check
Smart TVs, set-top boxes, and game consoles
Modern TVs are almost all equipped with dual-band modules, but in the 2013-2015 models of the middle and budget segments (Samsung J series, LG LF series) often encountered limitations. For viewing 4K content through built-in apps (Netflix, YouTube), 5 GHz support is critical, otherwise the video will constantly buffer.
Game consoles went their own way. PlayStation 4 (original and Slim) only have a 2.4 GHz Wi-Fi module, which is a serious bottleneck for online gaming. 5 GHz support was only added to the PS4 ProThe Xbox One and Xbox Series X/S support 5 GHz across all models. The Nintendo Switch also supports both bands, improving multiplayer stability.
TV set-top boxes deserve special attention. Budget "bells and whistles" like Xiaomi Mi Stick (first generation) or older versions Amazon Fire TV often lack 5 GHz support. When purchasing a new set-top box (for example, Apple TV 4K or Nvidia Shield TV) the presence of Gigabit Ethernet or Wi-Fi 5/6 is standard.
| Device | 5 GHz support | Note |
|---|---|---|
| PlayStation 4 (Fat/Slim) | ❌ No | 2.4 GHz only |
| PlayStation 4 Pro / PS5 | ✅ Yes | Required for 4K HDR |
| Xbox One (all models) | ✅ Yes | 802.11ac support |
| Nintendo Switch | ✅ Yes | Improves online gaming |
| Apple TV (4th generation and newer) | ✅ Yes | Wi-Fi 5 and higher |
⚠️ Attention: Menu interfaces and setting item names may vary depending on the firmware version of your TV or console. Always consult the manufacturer's official documentation for your specific model.
Smart Home: IoT and the Limitations of Low-Cost Devices
Paradoxically, in the era of Wi-Fi 6, most smart home devices (light bulbs, sockets, sensors) still operate exclusively on the 2.4 GHz frequency. This is done deliberately: 2.4 GHz has a longer range and lower power consumption, which is critical for batteries. Popular brands like Xiaomi, Tuya, TP-Link Kasa use single-channel chips.
If you try to configure such a light bulb while your phone is connected to a 5 GHz network, the setup process will likely fail. Your phone will simply not detect the device. To successfully configure it, you'll need to temporarily switch your smartphone to a 2.4 GHz network or use guest network mode if your router allows band isolation.
More advanced devices such as robotic vacuum cleaners (Roborock, Xiaomi Vacuum) and high-resolution IP cameras are already gaining widespread support for 5 GHz. This allows for video streaming without the latency and compression artifacts that are inevitable in the congested 2.4 GHz band.
- 💡 Lamps and sockets: Almost always only 2.4 GHz.
- 📹 IP cameras: Budget - 2.4 GHz, professional - Dual Band.
- 🤖 Vacuum cleaners: New models (since 2020) often have 5 GHz.
