How to increase Wi-Fi speed on a Xiaomi phone: from settings to hidden parameters

Smartphone owners Xiaomi, Redmi And Poco Often encounter a situation where the internet on your device is unstable, the connection speed drops, and videos constantly buffer. Problem may not be a malfunction of the device itself, but rather a specific setting of the operating system MIUI or HyperOS, which aggressively optimize background processes.

Fortunately, most of these limitations can be bypassed using standard tools, without resorting to reflashing or complex manipulations with root rightsIn this article, we'll take a detailed look at why Xiaomi sometimes has poor Wi-Fi reception and what specific steps can help you get the most out of your router.

First, you should make sure that the problem lies in the smartphone's software, and not in physical damage to the antenna module or a weak signal from the provider. Diagnostics It starts with a basic understanding of how your phone interacts with the wireless network.

Analysis of frequency ranges and communication channels

The first step to speeding up your internet is choosing the right frequency. Modern routers support two main bands: 2.4 GHz And 5 GHz. If your smartphone Xiaomi is in close proximity to the router, it is critical to switch to 5 GHz.

The 2.4 GHz band is heavily congested, with microwave ovens, Bluetooth headsets, wireless mice, and neighbors' networks all using it. This creates interference that reduce actual channel throughput. At the same time, 5 GHz provides higher data transfer rates, although it has a shorter range.

However, if you're far from a hotspot, your phone may struggle to maintain a weak 5 GHz signal instead of switching to the more stable 2.4 GHz. In this case, it's best to force-select the desired network in the connections menu.

⚠️ Attention: The router settings interface may vary depending on the model (Keenetic, TP-Link, ASUS). If you're unsure, consult your provider's instructions, as incorrect settings may temporarily disable network access.

It's also worth checking whether the "smart switching" feature is enabled on the router itself, which combines both bands under one name. For phones Xiaomi Sometimes it is more useful to have two different network names (SSIDs) so you can manually manage the connection.

Setting up privacy and MAC addresses

One of the most common causes of slow speeds on Android 10 and newer is the MAC address randomization feature. By default, the system MIUI generates a random address for each connection, which increases safety, but may cause conflicts with older routers or filters.

To fix this, go to your Wi-Fi settings, click the arrow next to your network name, and find "IP Settings" or "Privacy." Here, change the value from "Random MAC" to "Device MAC Address."

  • 📱 Open Settings and go to the section Wi-Fi.
  • 🔗 Click on your network name or the gear/arrow icon on the right.
  • 🔒 Find the item Privacy (or MAC address type).
  • ✅ Select an option Use the device's MAC address.

After changing the setting, the phone will reconnect to the network. This method is especially effective if you have a smart home system installed or if your router has strict access filters.

Optimizing DNS servers for faster response times

Often, the problem isn't file download speed, but rather a slow response time when opening pages. This can be resolved by changing the default DNS servers provided by your ISP. Standard DNS may work slowly or block access to some resources.

In the Wi-Fi settings on Xiaomi You can specify the addresses of fast and reliable servers from Google or Cloudflare. This will reduce server response time and speed up the loading of heavy websites.

DNS provider Preferred DNS Alternative DNS
Google Public DNS 8.8.8.8 8.8.4.4
Cloudflare 1.1.1.1 1.0.0.1
OpenDNS 208.67.222.222 208.67.220.220
Quad9 (Security) 9.9.9.9 149.112.112.112

To change the settings, go to the properties of your Wi-Fi network, click on “IP Settings” and select Static. In the fields that appear DNS 1 And DNS 2 Enter the values ​​from the table above.

Why does this work?

DNS (Domain Name System) translates human-readable website addresses (such as google.com) into the digital IP addresses of computers. If the provider's server is overloaded, this translation takes a long time. Using third-party DNS bypasses the provider's bottleneck.

Reset network settings and delete profiles

Over time in the operating system Android Network configuration errors accumulate. The phone may attempt to connect to a network with outdated encryption parameters or become stuck on a channel with a poor signal.

A radical but effective method is to completely reset the network settings. Important: This action will delete all saved Wi-Fi passwords, Bluetooth pairings, and mobile network settings, but will not affect your personal files, photos, or apps.

You can perform a reset through the system recovery menu or using standard tools:

  • 🛠 Go to SettingsConnection and sharing.
  • 🔄 Find the item Reset Wi-Fi, Mobile Networks, and Bluetooth.
  • ⚠️ Click Reset settings and confirm the action with the unlock password.
  • 📡 After rebooting, re-enter your Wi-Fi password.
⚠️ Attention: Before resetting, make sure you remember your Wi-Fi network password and SIM card PIN, if you have one, as you will have to enter them again.

Users often forget that their phone may have "Data Saver" or "Speed ​​Master" modes enabled, which artificially limit background app activity, which also affects perceived speed.

Using the engineering menu and hidden functions

For advanced users Xiaomi Provides access to advanced settings through special codes. However, caution is advised: changing parameters in the engineering menu without understanding them may lead to unstable operation of the communication module.

One useful setting is network priority. In some versions MIUI You can force your phone to scan the air more often and switch to clearer channels. A code is often used to access the test menu. ##4636##, although on newer versions of Android it may be blocked.

adb shell settings put global wifi_scan_throttle_enabled 0

This command is entered through a computer with installed ADB (Android Debug Bridge) disables Wi-Fi scanning throttling. By default, Android limits the frequency of network scans to save battery life, which can interfere with fast switching between access points.

The influence of cases and physical interference

Physical factors shouldn't be ignored. Antennas in smartphones Xiaomi are often located at the top or bottom of the case. If you're using a case with metal inserts, magnetic closures, or just a very thick protective case, this may screen signal.

Try removing the case and checking the speed. Also, pay attention to how you're holding the phone. Covering the antenna area (often the bottom or sides) with your palm will cause a sharp drop in signal strength.

  • 🧲 Remove magnetic holders from the antenna area.
  • 📱 Remove the thick silicone or metal dough cover.
  • 👐 Change your grip on the device if your speed drops in a certain position.

Furthermore, the router should not be placed in an alcove, behind a TV, or next to a microwave. Metal surfaces and mirrors also reflect the signal, creating dead zones.

FAQ: Frequently Asked Questions

Why is the Wi-Fi speed on my Xiaomi Redmi slower than on other phones?

This may be due to aggressive battery optimization in MIUI, which limits Wi-Fi operation in the background. Also, some budget models are equipped with single-stream Wi-Fi modules, which are physically unable to deliver high speeds.

Does the Wi-Fi Analyzer app help?

The app itself doesn't speed up your internet, but it does show how busy your router's channel is. This allows you to manually switch the router to a free channel through its web interface, which will significantly improve stability.

Do I need to update my router firmware?

Yes, router manufacturers regularly release updates that improve wireless connection stability and fix security issues. Check your router's admin panel for the latest firmware.

Does having Bluetooth enabled affect Wi-Fi speed?

Yes, since Bluetooth also operates in the 2.4 GHz band. When actively using wireless headphones or speakers, Wi-Fi speeds on this frequency may decrease due to signal interference.

What to do if nothing helps?

If software methods and settings changes don't work, the problem may be with the smartphone's hardware (a loose antenna connection) or a faulty router. Try connecting to a different Wi-Fi network for diagnostics.
