How to Speed ​​Up Wi-Fi on Xiaomi: A Complete Guide

Slow internet on a smartphone is one of the most annoying problems that owners face. Xiaomi, Redmi And PocoWhen videos take forever to load and pages won't open, you might be tempted to throw away your device or change your provider. However, often the problem lies not with the hardware, but with software settings that can be optimized.

In this article we will discuss technical nuances Wireless module operation in MIUI and HyperOS. You'll learn how to choose the right frequency, configure DNS servers, and eliminate background processes that consume bandwidth. This will allow you to get the most out of your data plan.

Before moving on to complex steps, it's worth ruling out trivial factors. Check if your router has a speed limit, and make sure your data plan actually offers high speeds. If your provider is OK, move on to setting up your smartphone.

Diagnostics of the current network state

The first step should always be an objective assessment of the situation. Don't rely on the feeling that "it seems slow." Use built-in or third-party tools to measure your actual speed. On smartphones Xiaomi often the app is pre-installed Security, which has a basic tester, but for in-depth diagnostics it is better to use specialized software.

Run a speed test through your browser or an app like Speedtest by Ookla. Pay attention to the ping and jitter values. A high ping (more than 50-70 ms) indicates routing issues or channel congestion, even if the advertised download speed is high. A slow upload speed may indicate a weak signal or interference.

⚠️ Please note: Test results may vary significantly depending on the time of day. In the evening, when neighbors are actively using the internet, the airwaves are overloaded, and speeds may drop.

Check what frequency your device is currently operating on. Often, the phone "hangs" on the congested 2.4 GHz band, ignoring the free 5 GHz. To check, use the engineering menu or third-party utilities like WiFi AnalyzerThis will help you understand whether it makes sense to change the router settings or whether reconnecting your smartphone is sufficient.

Compare the speeds on different devices. If the speed is high on a laptop or another phone, then the problem is localized on yours. XiaomiIf the connection is slow everywhere, you should contact your provider or reboot your router.

Switching to the 5 GHz band

The most effective way to speed up your connection is to switch to the 5 GHz frequency. The 2.4 GHz band, which is the default on many older routers, is heavily polluted. Microwaves, Bluetooth headsets, and neighbors' networks often interfere with the signal, causing interference and slowing down speed.

The 5 GHz band offers higher throughput and lower latency. However, it has a drawback: it's less effective at penetrating walls. Therefore, for maximum speed, it's important to have the router within line of sight or behind one non-load-bearing wall.

• 📶 Access your router settings via a browser (usually the address is 192.168.0.1 or 192.168.1.1).
• 🔧 Find the section Wireless or Wireless mode.
• ⚡ Make sure the 5 GHz network is enabled and has a different name (SSID) than the 2.4 GHz network.
• 📱 On the phone Xiaomi Forget the old network and connect to a new one with a name containing "5G".

Modern routers often have a "Smart Connect" feature enabled, which combines both frequencies under one name. The phone itself decides which one to connect to. Sometimes the algorithm Xiaomi It's making a mistake and clinging to the weak 2.4 GHz band. In this case, it's better to manually separate the networks in the router settings, giving them different names, for example, Home_WiFi And Home_WiFi_5G.

After switching, you should notice a significant speed increase, especially if your plan allows speeds above 100 Mbps. On the 2.4 GHz frequency, it's rare to achieve real speeds above 40-50 Mbps due to channel congestion and interference.

Configuring DNS to speed up response times

A common cause of slow internet isn't low download speeds, but rather slow response times from domain name servers (DNS). When you enter a website address, your phone asks your provider's DNS server where it's located. If your provider's server is overloaded, the page will load slowly, even if you have a broadband connection.

Changing your DNS to public, fast servers from Google or Cloudflare often works wonders. Pages load instantly, and the feeling of "sticking" when clicking links disappears. This is especially true for mobile networks and home Wi-Fi with unstable routing.

Configure DNS on Xiaomi There are two ways. The first is through the settings of a specific Wi-Fi connection. Go to Settings → Wi-Fi, click on the arrow next to your network, select IP settings (static) and enter the DNS 1 and DNS 2 addresses.

The second, more universal method, works at the level of the entire Android 9 system and above, including MIUI And HyperOSIt does not require changing the IP to a static one and applies to all networks.

Menu path: Settings → Connection and Sharing → Private DNS

In the window that opens, select "DNS Provider Hostname" (or "Manual") and enter the address: dns.google or 1dot1dot1dot1.cloudflare-dns.comAfter saving, the system will reconnect and requests will begin to be processed faster.

Optimizing MIUI and HyperOS settings

shell MIUI is known for its aggressive use of background processes and power saving. These features sometimes interfere with the normal operation of the network module. The system may limit background activity of apps, leading to delays in notifications or content updates.

Check your power saving settings. Go to Settings → BatteryMake sure important apps (browser, messaging apps, streaming services) don't have a hard limit on background activity. It's best to select "Unlimited" mode for frequently used apps.

Also worth noting is the "Wi-Fi Assistant" feature. It allows the phone to automatically switch to mobile data if the Wi-Fi signal becomes too weak. This prevents downloads from stalling in "dead zones" in your apartment.

Another hidden setting is game acceleration. In the app Security there is a section Speeding up games (Game Turbo). If you add an app to this feature, the system will prioritize its network traffic, pushing background processes into the background. This is useful not only for games but also for video calls.

Secret code for checking connection quality

Enter the code ##4636## In the dialer. The engineering menu will open. Select "Phone Information." Here you can view the signal strength (dBm) and change the preferred network type, but be careful: incorrect settings can temporarily disable the communication module.

Reset network settings and update software

Accumulated network module configuration errors can cause unstable operation. If none of the above helps, reset your network settings. This won't delete your personal photos or contacts, but it will forget all saved Wi-Fi passwords and Bluetooth pairings.

To perform a reset, go to Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothConfirm the action and reboot the device. After turning it on, re-enter the router password. This often resolves issues with constant connection drops.

Don't forget about system updates. Engineers Xiaomi They regularly release patches that fix Wi-Fi driver bugs. Go to Settings → About phone and check for updates. Sometimes the issue is known and has already been fixed in a new version. MIUI or HyperOS.

⚠️ Important: Before updating the firmware, ensure the battery is at least 50% charged and the Wi-Fi connection is stable. Interrupting the update may cause serious system malfunctions.

Also check for updates to system apps through the store. GetApps or Google PlayWireless drivers are sometimes updated independently of the main OS version.

Hardware and external factors

Physical limitations shouldn't be discounted either. A phone case, especially a metal one or one with a magnetic clasp, can shield the antenna. Remove the case and check the speed again. If the difference is significant, consider replacing it with a thinner one or one with cutouts for the antennas.

The router's location is also critical. Don't hide it in a closet, behind a TV, or on the floor. The best location is in the center of the apartment, at a height of 1.5-2 meters, in an open area. The router's antennas should point vertically upward.

If you live in an apartment building, the airwaves may be so congested that even 5 GHz will work intermittently. In this case, it might be worth downloading a Wi-Fi network analyzer app, finding the least congested channel, and manually entering it in your router settings.

In rare cases, the problem may lie with the smartphone's Wi-Fi module itself, especially if the device is several years old. If resets and firmware updates don't help, but the network works fine on other devices, diagnostics at a service center may be necessary.

Frequently Asked Questions (FAQ)

Why does Xiaomi's Wi-Fi keep disconnecting on its own?

This is most often a power-saving feature. Go to Wi-Fi settings, click the gear icon next to the network, and make sure "Connect in sleep mode" or something similar is enabled. Also, check the battery settings for system services.

Does having Bluetooth enabled affect Wi-Fi speed?

Yes, it does, especially if both modules operate at 2.4 GHz. They interfere with each other. If you need maximum speed, try disabling Bluetooth or, more effectively, switching Wi-Fi to the 5 GHz band, which doesn't interfere with Bluetooth.

Should I use booster apps from the Play Market?

Most of them are dummies. They simply flush the DNS cache or switch to airplane mode, which you can do yourself. Moreover, such apps often consume resources and display ads. Built-in tools Xiaomi usually enough.

How can I check if my ISP is slowing me down?

Connect your computer to the router via a cable (LAN) and test the speed. If the speed is slow via cable, the issue is with your ISP or router. If the speed is fast via cable but slow via Wi-Fi on your phone, the issue is with your wireless connection or phone settings.

Can a virus slow down Wi-Fi?

Theoretically, yes, if the virus is mining cryptocurrency or sending spam in the background. However, on Android devices with an antivirus installed and apps downloaded only from official stores, this is rare. Check your installed apps for any suspicious programs with administrator rights.
