How to Improve WiFi on Xiaomi Phone: A Complete Guide

Modern Xiaomi smartphones, which are based on the shells MIUI or HyperOS, have powerful wireless modules that can support high data rates. However, users often face a situation where the stated speed of the provider is not achieved, and the connection periodically breaks or works unstable in distant rooms. This can be caused by a variety of factors, from congestion of air by neighboring routers to software failures in the Android operating system.

Before you blame a smartphone manufacturer or provider, it’s worth doing a comprehensive diagnosis and optimization of settings. Improvement of WiFi signal is a process that requires a consistent approach, from checking the physical location of the device to changing hidden system parameters, and in most cases, the problem is solved without buying additional equipment or complex repairs.

In this guide, we will look at proven methods that will help you get the most out of your wireless connection.

and more advanced techniques, including the work with DNS The right configuration will not only speed up page loading, but also reduce ping in online games, which is critical for comfortable use of the smartphone.

Analysis of the current state of the network and diagnosis of problems

The first step is to understand what is interfering with normal connectivity. Often users mistakenly believe that low speed is the fault of the phone, when in fact the channel may be just overloaded. First, you need to assess the signal level and the number of networks available in your radius. Android's built-in tools provide basic information, but for deep analysis, it is better to use the tools to get the data.

WiFi diagnostics can identify dead zones and channels that are clogged with neighborhood routers that create interference.

One of the best programs for this purpose is WiFi Analyzer, or built-in engineering mode, if it's available on your Redmi or Poco model. These tools show a real-time frequency load schedule. If you see your router running on a channel where 5-6 more networks are concentrated, the speed will inevitably drop due to data packet collisions.

⚠️ Warning: Don't just rely on the number of sticks in the status bar, they're the power of the signal, not the quality or the noise level.

Also worth paying attention to is the security protocol version. If your router still uses WEP or old WPA, it can limit connection speeds and make the network vulnerable. Xiaomi smartphones are optimized to work with WPA2/WPA3, and switching to these standards often yields tangible performance gains.

• 📡 Use applications like WiFi Analyzer to view congestion.
• 📶 Check the signal level at different points in the apartment to find areas of poor reception.
• 🔒 Make sure that you use a modern encryption protocol. WPA2-PSK or WPA3.

Basic optimization of router settings for Xiaomi

Customizing the signal source itself, the router, is the foundation of a stable connection. Many devices default on mixed mode or 2.4 GHz, which is highly susceptible to interference from microwaves, Bluetooth headsets and neighborhood networks. Switching to the 5 GHz bandwidth is the most efficient way to increase channel capacity.

Range. 5 GHz provides faster data rates and is less susceptible to interference, but has less penetration through walls. If your Xiaomi smartphone and router support this standard, be sure to separate networks (give them different names, for example, give them different names, Home_2.4 and Home_5G) and connect the phone to the network. 5 GHz for high-speed tasks, such as streaming 4K videogame.

Another important parameter is channel width. For a 2.4 GHz band, 20 MHz is considered the optimal width, as this minimizes intersections with other networks. For 5 GHz, you can safely set 40, 80 or even 160 MHz if the equipment allows, and it is also worth checking whether the "energy saving" feature on the router itself is included, which can reduce the transmitter power.

💡

If you have a dual-band router but one network name (Smart Connect), try dividing them in the settings. Xiaomi smartphones sometimes misalign between frequencies, preferring a fast but distant 2.4 GHz instead of a close 5 GHz.

Don't forget the router's physical location. The antennas should be vertically directed, and the device should be raised higher and placed in the center of the apartment, away from metal objects and mirrors that reflect radio waves.

Setting up DNS and network parameters on a smartphone

Often the problem is not channel speed, but the slow response of name servers (DNS), Who converts domain names into IP-Standard addresses. DNS-Your ISP's servers may be slow or overloaded. DNS Faster public servers, such as Google DNS Cloudflare can significantly speed up the opening of websites.

To change these settings on Xiaomi, go to Settings → WiFi, click the arrow next to your network name, and select DNS Settings. You can manually write addresses here. Low-latency DNS use is especially noticeable when loading heavy pages with multiple elements or when using applications that constantly access the server.

In addition, in modern versions of Android and MIUI The "Private" function is available DNS" (Private DNS), coder DNS-requests and often uses more reliable servers by default. Activating this feature can bypass some of the limitations of the provider and improve response speed.

⚠️ Attention: With manual registration DNS Make sure you enter the numbers correctly. A single character error will result in a total loss of WiFi internet access, although the connection indicator may show activity.

Network resetting and energy saving management

Aggressive energy saving policies in MIUI and HyperOS shells often cause WiFi modules to go to sleep or to run unstable to save battery life.The system can limit background network services activity, leading to delays in receiving notifications or connection breaks when the screen is off.

To fix this, you need to find battery settings for specific system services. Go to Settings → Applications → All applications, click three dots in the corner, select Show Systems and find WiFi-related processes (e.g. Wi-Fi, Google Play Services). From the Charge Savings menu, select No Limits. This will prevent the system from strangling the network module.

If the software settings don't work, the effective method is to completely reset your network settings, which will remove all stored WiFi passwords, paired Bluetooth devices and mobile network settings, returning them to factory status, eliminating the accumulated configuration file conflicts.

To perform the reset, go to Settings → Connection & Sharing → Reset WiFi and mobile networks. Once the procedure is done, the phone will reboot and you will need to re-enter the password from your wireless network. Often this solves problems when the phone gets stuck on the old router settings after it is replaced or updated firmware.

• 🔋 Turn off energy savings for system network services.
• 🔄 Reset your network settings if the problem persists for a long time.
• 📱 Make sure the latest version of the firmware is installed on the phone.

Use of engineering menu and hidden functions

For advanced users, Xiaomi provides access to an engineering menu where you can fine-tune the parameters of the radio module. This menu is logged in through a set of special code in the Phone application. For most Xiaomi devices, code ##6484# or #4636### works.

In the WiFi testing section (usually called the WiFi Test or in the general hardware testing menu), you can actually receive power in dBm (dBm). The normal value is from -30 to -60 dBm. If the value is below -80 dBm, the connection will be unstable.

Also worth mentioning is the feature "Wi-Fi Assistant", built into the MIUI. It allows the phone to automatically switch to the mobile Internet if the WiFi signal becomes too weak, ensuring continuity of connection. → WiFi → WiFi Assistant.

In some cases, changing the region in the router settings helps. If you are in an apartment building, choosing a region with less stringent signal power restrictions (for example, the United States or Australia, if the legislation and the router firmware allows it) can slightly enhance the signal.

The Impact of Third-Party Apps and Malware

Do not discount the impact of installed applications on the network, some programs, especially so-called "Internet accelerators", "memory cleaners" or VPN-These services can create virtual network interfaces that conflict with the Android system stack, which leads to more ping and packet loss.

Check the list of installed applications and remove those that have access to the network and do not cause your trust. Pay special attention to applications that work in the background. If after removing suspicious software, the situation improved, then it was the software conflict.

In addition, viruses and miners can use your Internet channel for their needs, greatly reducing the available speed. Regularly checking your phone with an antivirus, for example, a built-in security scanner Xiaomi or a third-party solution from a reputable vendor, will help to eliminate this possibility.

💡

Third-party applications to “boost” the signal are often useless or even harmful, and they cannot physically increase the antenna power, but only change the program priorities that are already configured in the system.

In conclusion, software methods have their limits: If a WiFi module is physically damaged (for example, after falling or getting moisture), no adjustments will help, in which case a diagnosis is required at the service center.
