What Xiaomi phones support Wi-Fi 5 GHz: a list of models and settings

The modern Internet requires high speed and stability of connection, especially when watching video in 4K or online games. Many users wonder which Xiaomi phones support 5g wifi, as this range provides maximum bandwidth in noisy ether. Unlike the usual 2.4 GHz frequency, 5 GHz allows you to transfer data much faster, but has its own features coverage.

Xiaomi has been implementing dual-band support in its devices for several years, starting with flagship lines and gradually descending to the budget segment. However, having a module does not guarantee automatic connectivity unless the router is configured accordingly. In this article, we will discuss in detail the compatibility of different series of smartphones, how to check frequency support and methods for solving typical connection problems.

Technological features of dual-band networks

Dual-band Wi-Fi implies the operation of the wireless module of the smartphone in two frequency bands at once: 2.4 GHz and 5 GHz. 802.11ac standard (Wi-Fi 5) and the newer 802.11ax (Wi-Fi 6) are based on high frequency, allowing you to achieve speeds not available to the old standard. Xiaomi smartphones equipped with the appropriate chipsets can switch between the bands automatically or work only at high frequency for maximum performance.

The main advantage of 5 GHz is less interference, since most household appliances and neighbourhood routers operate at a crowded frequency of 2.4 GHz. Smartphones with this technology demonstrate lower ping in games and no jerks when streaming heavy content. However, the range of the signal at high frequency is always smaller, and the ability to penetrate walls is much lower.

It’s important to understand that band support depends not only on the MIUI or HyperOS shell, but also on the physical module installed on the device board. Budget models of the past could have antennas optimized only for basic communication standards, which limited their capabilities in modern networks.

⚠️ Note: If your router gives away a network with the same name (SSID) For both bands, the phone can automatically switch to a weaker 2.4 GHz signal from a distance away. For forced use of 5 GHz, it is recommended to divide the network names in the router settings.

Xiaomi flagship series and 5 GHz support

The company’s flagship devices have always been equipped with advanced communication modules. Since the Xiaomi Mi 4 series, which was released a few years ago, support for dual-band Wi-Fi has become the standard for the top segment. All models of the Xiaomi Mi line, including the Mi 5, Mi 6, Mi 8, Mi 9 and Mi 11, are confident in the 5 GHz band.

Modern flagships like Xiaomi 13, Xiaomi 14 and their Pro/Ultra versions support the latest Wi-Fi 6E standard and even Wi-Fi 7 in some regions, which provides theoretical data rates of up to several gigabits per second with the appropriate router, and owners of these devices can expect to work steadily in congested apartment buildings.

Despite the experimental nature of some models, the company’s engineers have always paid special attention to communication modules. Mix 2, Mix 2s, Mix 3 and Mix 4 smartphones are fully compatible with high-speed networks.

To check the exact specification of your flagship, you can use technical documents or diagnostic applications. In the Settings → About Phone → All specs often indicate support for Wi-Fi standards. If it mentions 802.11ac or 802.11ax, then the device is guaranteed to see 5 GHz networks.

Redmi and POCO smartphones: affordable high-speed internet

Redmi and POCO sub-brands are a little more complicated, as frequency support was dependent on year of release and price segment. Early Redmi models (before Redmi Note 4) were often limited to only 2.4 GHz. However, since the Redmi Note 5 and later, the dual-band module has become commonplace.

The Redmi Note series (Note 7, Note 8, Note 9, Note 10, Note 11, Note 12, Note 13) is almost entirely 5GHz supported. The exception may be the most basic versions of "Lite" or models released specifically for certain markets with reduced characteristics. POCO F and POCO X gaming smartphones also always received full support for high frequencies, since Internet speed is critical for mobile gaming.

Redmi A or Redmi C series models may not support 5 GHz due to the savings on components. Before buying an inexpensive device, it is always worth checking the availability of a standard. 802.11a/n/ac official characteristics on the manufacturer's website.

It is worth noting that in some firmware for the global market (Global ROM) functionality may differ from the Chinese version (CN ROM).If you re-flash the device, make sure that the Wi-Fi module drivers work correctly in the new version of the OS.

Comparison of Wi-Fi modules in different series

To better understand the difference in connectivity, consider a comparison table of support standards across device generations to determine whether you should expect high speed from your particular device.

As you can see from the table, even mid-range devices like the Redmi Note have long been supported by fast networks. However, the most affordable models, such as the Redmi A series, are often left in the past, supporting only old protocols.

When choosing a new smartphone, note the presence of the letter “n” or “ac” in the Wi-Fi specifications. the absence of these designations often indicates the limited functionality of the wireless module.

How to check and set up 5GHz Wi-Fi on Xiaomi

If you are sure that your phone supports high frequency, but the network is not displayed, the problem may lie in router settings or regional restrictions.First you need to make sure that the router is actually broadcasting a 5 GHz signal. Go to the router control panel (usually at 192.168.0.1 or 192.168.1.1) and check the status of the wireless network.

On the smartphone itself, go to the Settings menu → Wi-Fi: If the router distributes two networks with different names (e.g., "Home" and "Home "Home_5G"), Just select the network with the console 5G. If the name is one, the phone will decide which frequency to use based on the signal level.

In some cases, resetting network settings helps. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This action will delete saved passwords, but can correct the communication module's software errors.

Typical problems and methods of their elimination

Users often face a situation where the phone sees a 5GHz network but does not connect to it or the speed remains low. one reason may be the router's outdated firmware. router manufacturers regularly release updates to improve compatibility with new smartphones.

Another common problem is the use of a narrow channel: For stable operation in the 5 GHz band, it is recommended to set the channel width 80 MHz. If you put 160 MHz, the speed will increase, but the range and stability can suffer, especially through walls.

⚠️ Warning: Don’t set the router too high in the hope of breaking through walls. At 5GHz, this often backfires — the phone “sees” the router, but its response signal is too weak for the router, and communication is cut off.

Also check whether the router is running on Legacy Mode only. Make sure you choose 802.11 a/n/ac/ax. If your phone appears to be connected to the router's client list as "g" or "n" then the connection is at low frequency or low speed.

💡

The stability of the 5GHz connection is highly dependent on the distance to the router and the number of physical obstacles; for large apartments, the use of Mesh systems is optimal.

The impact of regional settings on available frequencies

The region is the region that you see in your smartphone and router settings, and different countries allow different frequency bands and power levels, for example, in the United States and Europe, the set of channels available may differ, and if you bring a phone from China (CN Version) and use it with a European router, there may be conflicts.

Chinese versions of Xiaomi often do not support 5GHz channels used in Europe (e.g., 100+ channels), and vice versa. As a result, the phone may simply “not see” the network the router distributes, the solution may be to flash the device to a global version (Global ROM), which takes into account international standards.

In addition, in some countries there are restrictions on the use of certain frequencies for civilians. Smartphones sold officially in Russia and the CIS, usually have an unlocked set of frequencies compatible with local operators and providers.
