How to Increase Wi-Fi Speed on Xiaomi Phone: A Complete 2026 Guide

Slow Wi-Fi on Xiaomi smartphone is a problem that every third user faces. Even with a stable connection, the speed can “slow down” due to incorrect router settings, firmware features MIUI In this article, we will look at 10 proven ways to speed up the Internet on Redmi phones, POCO Mi – from basic settings to hidden functions of the engineering menu.

It’s important to understand that Wi-Fi speeds are not just dependent on your smartphone, but also on your router, network congestion, distance to the hotspot, and even the walls in your apartment. We’ll focus on the aspects that you can optimize on the phone’s side — without buying a new router or provider. All methods tested on current versions MIUI 14/15 Android 13/14.

If the speed is low after applying all the tips, the problem may lie in the provider (tariff restriction) or router (outdated firmware, weak processor), in which case it is worth checking the speed on other devices - for example, a laptop or tablet - and comparing the results.

1. Checking the current speed of Wi-Fi: tools and norms

Before you optimize, you need to understand how fast you are and whether it matches the stated provider. To test, use specialized applications — they are more accurate than the built-in tools Xiaomi.

Download one of the applications:

📊 Speedtest by Ookla is a classic test with servers around the world.
🌐 nPerf – analyzes not only the speed, but also the stability of the connection, delays and the speed of the connection.
📶 WiFi Analyzer – shows the load of channels, signal strength, interfering with networks.

Do 3-5 tests in different parts of the apartment and at different times of the day.

Provider's fare	Download speed (Mbps)	Ping (ms)	Stability
Up to 100 Mbps	70–95	10–30	No sharp drawdowns
100-300 Mbps	150–280	5–20	Fluctuations ±10%
300-500 Mbps	250–450	3–15	Fluctuations ±5%
1 Gbps and higher	500–900	1–10	Minimum fluctuations

If the real speed is 30% or more below normal, optimise it, and if the difference is minimal (5-10%), the problem may be in the provider’s servers or peak load (evening).

2. Optimization of Wi-Fi settings in MIUI

Firmware MIUI It hides a few useful features that can speed up or slow down a connection:

Open Settings → Wi-Fi and do the following:

Long click on the network name → «Change the network» → Set the box "Autoconnection»

Turn off the Smart Switch option (if any) – it can switch you to mobile data for no reason

Enable Wi-Fi Power Saving Mode (in some versions) MIUI It's called "Consumption Optimization») → Choose "Always»

Check that the protocol is on. WPA3 (if the router supports)-->

Pay special attention to the option “Wi-Fi Mode” (in some Xiaomi models it is hidden).

Go to Settings. → The phone.
Click 5-7 times on the MIUI version until the notification “You became a developer” appears.
Go back to the basic settings, open Additional → for developers.
Find the Wi-Fi mode and install it. 802.11n/ac/ax (depending on the router support).

Critical error of many users: the enabled mode 802.11b/g limiting speed 54 Mbps, even if the router supports 300+ Mbit/s. If the network disappears after the change of mode, return the settings back - your router is not compatible with the selected standard.

💡

If the Wi-Fi mode changes, try disabling Channel Aggregation in the router settings, which may conflict with some Qualcomm chipsets in Xiaomi smartphones.

3. Choosing the optimal Wi-Fi channel and frequency

Most routers automatically choose Wi-Fi, but not always optimal, and congested channels are one of the main reasons for low speeds and connection breakdowns.

How to check and change the channel:

Install the WiFi Analyzer (or analogue) application.
Go to the Channel Graphic tab and you will see which channels are occupied by neighboring networks.
For 2.4 GHz, select the least loaded channel from 1, 6, or 11 (they don’t overlap).
For 5GHz, select a channel with the minimum number of networks (usually in the 36-48 or 149-165) range.
Go to the router’s web interface (usually 192.168.1.1 or 192.168.0.1) and manually install the selected channel.

As for frequency:

📶 2.4 GHz - better through walls, but subject to interference: ~150 Mbps.
🚀 5 GHz - higher speed (up to 1 Gbps), but worse coverage. Optimal for devices in the same room with the router.
🆕 6 GHz (Wi-Fi) 6E) — Available only on flagships (Xiaomi) 13/14, POCO F5 There is almost no interference, but weak penetration through obstacles.

If your router supports Wi-Fi 6 (802.11ax), Turn it on in the settings. Xiaomi smartphones on Snapdragon chipsets 8 Gen 1/2 or Dimensity 9000 can be used OFDMA and MU-MIMO, which increases the speed of the loaded networks on 20–40%.

How to know if your Xiaomi Wi-Fi 6 is supported?

Open the Settings. → The phone. → Full specification. In the "Network" section, look for support for standards. 802.11ax or wifi 6/6E. If any, the smartphone is compatible with the new standard.

4. Reset network settings and cache

Accumulated network errors or a corrupted cache can slow down Wi-Fi, a technique that helps in 30% of cases where speeds suddenly drop for no apparent reason.

How to reset your settings:

Go to Settings → System and device → Additional → Resetting.
Select Network Reset (not to be confused with a full reset!).
Confirm the action and restart the phone.

After reset, you will have to re-enter Wi-Fi passwords, but will be deleted:

🔄 Save networks with incorrect parameters.
🗑️ Cash. DNS (It can slow down the loading of websites).
⚙️ Misconceptions VPN proxy.

If the reset didn’t help, try clearing the cache of the system applications responsible for the network:

Open Settings → Applications → Application Management.
Find and open your Wi-Fi (or Wi-Fi Direct) settings.
Press Warehouse. → Clear the cache.
Repeat for Google Play Services and Google Play Services.

⚠️ Warning: Do not clean the data (clean all data) from system applications - this can cause malfunctions in the phone.

5. Update firmware and Wi-Fi drivers

Manufacturers regularly release updates to fix bugs in the Wi-Fi module, and this is especially true on Xiaomi: in early versions. MIUI 13/14 There were bugs with connection to the networks 5 GHz and Wi-Fi 6.

How to update firmware:

Go to Settings → About the phone → System update.
Click on “Check Updates” and install the latest version of MIUI.
If there are no updates, but the problem is relevant, check the official website. MIUI — There may be a beta version available for your model.

If the speed hasn’t increased after the update, try to roll back to the previous version (if the problem appeared after the update).

🔙 Download the necessary firmware with Xiaomi Firmware Updater.
📱 Go to Settings. → The phone. → Version. MIUI → Press 10 times on the logo MIUI, to turn on firmware mode.
🔄 Select the downloaded file and confirm the rollback.

For advanced users, if the Wi-Fi driver is a problem, you can try to reflash the module through Fastboot. However, this is risky - if you make a mistake, the phone can lose communication. WCN6855 Xiaomi 13).

💡

Updating your firmware is the safest way to fix Wi-Fi software bugs. If there is a problem after the update, look for the cause in the router or provider.

Xiaomi has a hidden engineering menu where you can fine-tune the Wi-Fi module settings. Careful: improper changes can lead to loss of communication or overheating of the chipset.

How to open the engineering menu:

Open the Phone app.
Enter the combination: ##4636###.
Select Wi-Fi (or Wi-Fi Information) information.

Parameters that can be optimized:

📡 Wi-Fi frequency band – force 5 GHz (if the router supports).
🔄 Roaming aggressiveness – set 5 (average) for balance between stability and speed.
📶 Wi-Fi Verbosity Level – Turn on Moderate for detailed error log (helps with diagnosis).

For models on Qualcomm chipsets (most of them) Xiaomi/POCO) Additional settings available:

In the engineering menu, select:


1. Wi-Fi → Wi-Fi Driver Stats → Check "Enable Driver Logs" (enables driver logs).




2. Wi-Fi → Wi-Fi Power Save Mode → Install “Low” (reduces latency but increases battery consumption).




3. Wi-Fi → Wi-Fi Tx Power → Try the value of “High” (will boost the signal, but can reduce battery life).

⚠️ Warning: Changing the Wi-Fi Tx Power setting to a maximum value (Very High) can cause the module to overheat and automatically turn off Wi-Fi. Use only when critically necessary.

Alternative methods: from DNS before VPN

If the standard methods didn’t help, try the unobvious tricks:

1. Shift DNS-server

Provider's DNS They're often slowing down:

🌍 Cloudflare: 1.1.1.1 and 1.0.0.1
🌐 Google DNS: 8.8.8.8 and 8.8.4.4
🛡️ AdGuard DNS (blocking advertising: 94.140.14.14 and 94.140.15.15

How to change DNS to Xiaomi:

Long tap on the Wi-Fi network → «Change the network» → «Additionally».
In the Settings field IP select Static.
Please indicate the selected DNS field-wise DNS 1 and DNS 2.

2. Using VPN to circumvent restrictions

Some providers artificially limit the speed for certain services (torrents, video). VPN Could help get around it:

🔒 ProtonVPN – free rate with servers in 3 countries.
🚀 Warp (from Cloudflare) – Minimum speed losses.
🌍 NordVPN – paid, but with servers optimized for streaming.

3. Disabling background applications

Apps like Facebook, TikTok, or Mi Drive can consume traffic in the background.

Settings → Applications → Application management.
Select the application → Auto-start → Turn it off.
For full control, use the settings → Battery → Energy saving regime → Choose apps that don’t need to work in the background.

8. Hardware causes of low speed

If the software methods did not help, the problem may be in the hardware:

1. Damaged Wi-Fi module

Symptoms:

📉 Speed drops only on the phone, other devices are working normally.
🔄 Frequent connection breaks, even near the router.
🔥 The phone warms up in the upper part (where the module is located).

Solution: go to the service center. Xiaomi has a replacement Wi-Fi module. ~1 500–3 000 ₽ (model-wise).

2. Weak antenna.

Budget models (Redmi) 9A, POCO M3) They often save on antennas:

📶 Signal drops even at a small distance from the router.
🔄 Speeds are 5GHz lower than 2.4GHz (though it should be the opposite).

Solution: Use a repeater (signal amplifier) or a mesh system (e.g., Xiaomi Mi Mesh Router).

3. Processor overheating

When the chipset (Snapdragon or Mediatek) is heated, the trottlit (reduces performance), which also affects the speed of Wi-Fi.

🌡️ Processor temperature (annex) CPU Monitor).
🔥 The phone warms up when charging or playing.

Decision:

🧊 Remove the case during heavy use.
🔄 Close the background applications.
🛠️ Replace the heat paste (at the service center).

If the phone is older than 3-4 years (Redmi Note 5, Mi) A2), The problem may be battery wear. If it's under 20%, the processor limits performance, which also affects Wi-Fi. ~1 000–2 500 ₽).

FAQ: Frequent questions about the speed of Wi-Fi on Xiaomi

Why is the iPhone faster than Xiaomi?

Apple uses more expensive Wi-Fi modules (e.g. Broadcom instead of Qualcomm in most Xiaomi), iOS also optimizes network queries better, the difference can be as high as 20-30% in favor of the iPhone, especially on a weak signal. To close the gap: Update firmware MIUI Turn on Wi-Fi 6 in your router settings (if supported). Turn off Bluetooth, it can interfere at 2.4 GHz.

Can you increase the speed through ADB-team?

Yes, but it's risky. Some commands: adb shell settings put global wifi_supplicant_scan_interval 120 # Reduces network scanning interval (saves battery but can slow connection) adb shell settings put global wifi_idle_ms 5000 # Increases inactivity timeout (good for stability) Warning: Wrong commands can lead to network loss.Before experimenting, make a backup through Settings → System system → Backup.

Why does the speed drop at night?

Probable causes: 📡 Peak load on the provider – many users actively use the Internet in the evening. 🔄 Automatic software updates – Xiaomi can download updates on schedule. 🛡️ Deep Packet Inspection (DPI) — provider can restrict torrents or video.Solution: Disable auto updates in Settings → The phone. → Updating the system → Settings (⚙️) → Auto-update. Use it. VPN roundabout DPI. Call the provider and check if there are nightly tariff restrictions.

How to check if your neighbor is stealing my Wi-Fi?

Signs of burglary: 📉 Speed drops for no reason. 🔄 In the router settings (192.168.1.1) in the section DHCP Clients have unknown devices. 💡 The Internet light on the router flashes when you are not using the network. How to protect yourself: Change the Wi-Fi password to the Internet. WPA3 (Minimum length: 12 characters. WPS In the router settings. Enable filtering by MAC-Addresses (list of permitted devices).

Will replacing the router with Xiaomi Mi Router help?

Xiaomi routers (such as Mi Router) 4A Gigabit or AX6000) Well optimized for the brand's phones: 🔗 Mesh-network – seamless switching between points (useful for large apartments). 🚀 Wi-Fi 6 support – up to 3000 Mbps AX6000. 📱 Managing via Mi Home is more convenient than a standard web interface, but if your current router is modern (TP-Link Archer). AX50, ASUS RT-AX88U), There will be no speed gain, but the main thing is to set it up correctly (see sections above).
