How to speed up the Internet on Xiaomi: a complete guide to setup

The problem of low connection speeds on Xiaomi, Redmi and Poco smartphones is often a cause of irritation for users, especially when pages load for eternity, and video is constantly buffered. 4G/LTE, And so when you connect to your home Wi-Fi network, it could be because of software limitations. MIUI or HyperOS, the wrong settings DNS-servers or even the physical location of the router.

Before you blame the carrier or the provider, it is worthwhile to conduct a series of manipulations inside the gadget itself. Often standard system settings prioritize saving traffic and battery power at the expense of connection performance. In this article, we will discuss proven methods that will help you to make the most of your existing communication channel without using third-party software.

Now, you have to understand that the hardware constraints of the antenna module also play a role, but software optimization can do wonders. We're going to look at the engineer's hidden menus, the DNS settings, and how the communication modules work across different frequency bands. Let's get to the specifics.

Diagnostics of the current state of the network

The first step is always to be objective, not to rely on the subjective feeling of slow, but to use accurate tools, and Android or specialized applications will show a real picture of what is happening to your connection right now.

Run a speed test and pay attention not only to download rates, but also to ping. High ping can cause lags even at normal page load speeds. If the rates are significantly lower than the declared tariff, the problem lies in the device or local network.

• 📶 Speedtest by Ookla – a classic tool for measuring incoming and outgoing speed, as well as jitter.
• 🔍 Fing – lets you see which devices are connected to your Wi-Fi and not eat up the entire channel.
• 📡 WiFi Analyzer – shows the load of channels, which is critical for choosing the free frequency of the router.

⚠️ Note: If the speed is low when testing via mobile network, try extracting the SIM-So you can wipe the contacts and paste them back, and contact oxidation is a common cause of unstable connections on old sims.

Shift. DNS-servers to speed up response

One of the most effective and safest measures to speed up page loading is to change the page. DNS-Providers often use their own name servers, which can be overloaded or slow to respond to queries. DNS Google or Cloudflare often reduces the response time of sites.

On modern versions of MIUI and HyperOS, this can be done through the Private DNS function, which works at the DNS-over-TLS protocol level. This not only speeds up site opening, but also increases security by encrypting domain name requests. Old methods of prescribing DNS in Wi-Fi settings for each network separately are less effective here.

To set up, go to Settings → Connection and Sharing → Private DNS. The default is “Auto.” Select “DNS Host Name” (or “Manual”) and enter the server address. After saving, it is recommended to restart the smartphone to apply the changes.

💡

Use the address dns.google or 1dot1dot1dot1.cloudflare-dns.com for maximum response speeds on Google and Cloudflare servers respectively.

Mobile Internet and APN settings

If problems are observed mainly when using a mobile network, it is worth checking the access point settings (APN). Operators periodically update their gateways, and automatic settings that came once in SMS may be irrelevant or contain errors. Creating a new access point with the correct parameters often solves the problem of “floating” the Internet.

Go to Settings. → SIM-maps and mobile networks → Choice SIM-cards (your card) → Access points (APN). Click the button "New Access Point" or "Create" APN". It is important to enter the name correctly and APN, the other fields are better left empty or by default, unless the operator has indicated otherwise.

⚠️ Warning: Don't change the type APN (For example, default, supl on something else, if you don't know exactly why. APN It can completely disable the data transfer.

Also on the mobile menu, you should pay attention to the preferred network type: make sure you choose 4G/LTE or 5G (if supported) mode rather than 3G/2G. Sometimes the system switches to a slower communication standard in an attempt to save charge if the 4G signal is unstable. Forced 4G setting can help, but in areas of poor reception, communication can disappear completely.

Optimizing Wi-Fi Connection

In apartment buildings, 2.4GHz air is often overloaded with neighborhood routers and Bluetooth devices. If your router is dual-band, it is strongly recommended to switch your smartphone to a 5GHz network. This range provides significantly higher data rates, although it has a shorter range and less travel through walls.

The Wi-Fi settings on Xiaomi also feature Wi-Fi Assistant, which allows the phone to automatically switch to mobile internet if the Wi-Fi signal becomes too weak, but sometimes this function does not work properly, creating the illusion of a connection break. Try to turn it off in the Settings menu → Wi-Fi → Wi-Fi Assistant to lock the connection.

Another important point is to disable randomization. MAC-Some older routers or specific security settings may conflict with this Android privacy feature. Go to the properties of your Wi-Fi network, look for "Privacy" or "MAC-"address" and select "MAC-"Device address" instead of random.

• 📶 Channel width: In router settings for 2.4 GHz, set 20 MHz (less interference), for 5 GHz - 40 or 80 MHz (higher speed).
• 🔒 Security protocol: Make sure you are using WPA2/WPA3. Old. WEP Open access can limit speed.
• 🔄 Router reboot: A banal but effective method of cleaning the cache and reconnecting to the provider.

Reset network settings and engineering menu

If software failures accumulate, a complete reset of network settings may be required, which will return all Wi-Fi, Bluetooth and mobile internet settings to factory values. Importantly, passwords from Wi-Fi networks will be deleted, they will have to be re-entered, but this often solves problems with permanent breaks.

For more advanced users, there is a Xiaomi engineering menu called by the code ##6484## or ##4636##. In the section "Testing" → "Phone Information" you can find the menu "Menu of preferred network." Here you can force the radio module to switch mode, for example, select LTE Only (LTE only), so that the phone does not waste time searching for 2G/3G networks. However, use this with caution: in "LTE Only" mode, you may not receive normal voice calls unless VoLTE technology is enabled.

Resetting Path: Settings → Connection and Sharing → Reset Wi-Fi, Mobile Networks and Bluetooth → Resetting Settings

The Impact of Traffic Savings and Background Processes

MIUI is famous for its aggressive power optimization, which often stifles background processes, including application network activity. If you have Traffic Saving or Charge Saving mode on, the system can artificially limit the speed or frequency of updates for programs you are not using right now.

Check your traffic savings settings in Settings → Connection and Sharing → Traffic. Make sure that important applications (messengers, navigators, mail) are free of restrictions. Also, in the Battery section, it is worth checking whether the hard power saving mode is included, which throttles (reduces performance) of the processor and communication modules.

The accumulated cache of Google Play system services and the network services themselves can also cause crashes. Clearing the cache of the Google Play Services and Settings app (via the app menu) sometimes helps restore the normal operation of the network stack without completely resetting.

Aggressive battery saving is the main enemy of stable internet on Xiaomi. Always add important apps to exceptions ("No Limits").
