How to strengthen Wi-Fi on Xiaomi phone: from settings to hardware solutions

Did you notice that Xiaomi catches Wi-Fi worse than other devices in the house? Pages load forever, video slows down, and instant messengers hang even next to the router, POCO Mi is more common than you think, and it's not always the phone that's to blame. 80 percent of the time, network settings, neighbor interference, or outdated hardware are to blame.

In this article — 10 We will look at the proven ways to enhance Wi-Fi on any Xiaomi phone, from basic settings to advanced router tricks, POCO F5) Often lose contact when switching between 2.4 GHz and 5 GHz, how to fix the sticking on the weak channel and when it's time to buy a repeater. MIUI 14/15 Android 13/14.

1. Check the current strength of the Wi-Fi signal

Before you set up something, measure the real signal strength. Xiaomi does this without third-party apps:

1. Open the Settings. → Wi-Fi.
2. Slip on the name of your network and a window with details will open.
3. Note the signal level option (usually displayed as stripes or in dBm).

Optimal values:

• 🟢 -30 dBm -60 dBm is a great signal.
• 🟡 -60 dBm -70 dBm - medium (brakes possible).
• 🔴 -70 dBm and below - weak (need to be reinforced).

If your signal is lower -70 dBm, but other devices (laptop, tablet) are working normally -- the problem is the phone. If everything is slowing down, it's the router or the interference.

2. Optimize your Wi-Fi settings on your phone

MIUI It hides a few useful features that can amplify the signal:

Enable "Smart Wi-Fi Switching"

This feature automatically switches the phone between 2.4 GHz and 5 GHz depending on the signal strength.

1. Settings → Wi-Fi → Additionally (⋮) → Additional functions.
2. Turn on the "Smart Wi-Fi Switch."

⚠️ Note: On some models (Redmi Note 12 Pro)+, POCO X5 Pro) this option may not work stable - if the connection starts to break after activation, turn it off again.

2.2. disable "Saving Wi-Fi traffic"

MIUI By default, it limits the background activity of applications on the network, which saves battery life, but impairs stability:

1. Settings → Battery and productivity → Savings in battery charge.
2. Select “No Limits” or add the desired applications to the exceptions.

2.3 Reset the network settings

If the problem started after the update MIUI or changing routers, resetting the network often helps:

1. Settings → About phone → Resetting → Resetting Wi-Fi, mobile network and Bluetooth settings.
2. Confirm the action (password is not required).

3. Set up a router for maximum compatibility with Xiaomi

Often the problem is not the phone, but the wrong router settings, especially for low-end models TP-Link, D-Link or Xiaomi Mi Router.

3.1. Select the correct channel and bandwidth

If the router is running on an automatic channel, it can select the congested frequencies.

• 📶 2.4 GHz: Channel 1, 6 or 11 (not overlapping). Width 20 MHz (not 40 MHz!).
• 🚀 5 GHz: Channels 36-48 or 149-165 (less loaded. Width — 80 MHz.

How to change (for example, Xiaomi Mi Router):

1. Go to the router control panel (usually 192.168.31.1).
2. Wi-Fi settings → Additional settings → Canal.
3. Select the channel manually and save it.

3.2. Enable compatibility mode with 802.11n/ac

Some Xiaomi (especially older models) 6xx) They are not working well with the new Wi-Fi standard. 6 (802.11ax). Try to force-on 802.11n/ac:

• In the router panel, find the Wireless mode → Wi-Fi standard.
• Choose «802.11n/ac» instead of "auto" or «802.11ax».

💡

If you have a dual-band router, give the networks different names (e.g., a different router, MyWiFi_2G and MyWiFi_5G). This will help Xiaomi to switch between frequencies faster.

3.3 Update the router's firmware

Outdated router software may conflict with MIUI. Check for updates:

1. In the control panel of the router, find the section Update Software or Firmvar.
2. If there is a new version, upgrade (do not turn off power during the process!).

4.Use alternatives DNS speed up

Slow Wi-Fi may not be due to signal, but to long response times. DNS-ISP servers. Replace them with faster ones:

1. Go to Settings. → Wi-Fi.
2. Put it on your net. → «Change the network» → «Additional parameters».
3. In the field «DNS» enter: 🔹 1.1.1.1 (Cloudflare) for speed; 🔹 8.8.8.8 (Google) - for stability; 🔹 76.76.76.76 (Yandex) – for Russian websites.

After shift. DNS Reboot your phone. Use Speedtest to check your speed.

5. Hardware methods of signal amplification

If software methods don't work, it's time to look at hardware solutions, which will require investment, but will yield a guaranteed result.

5.1 Buy a Wi-Fi repeater (repeater)

The repeater increases the coverage of the router by repeating its signal.

• 📡 Xiaomi Mi Wi-Fi Repeater 2 - budget, supports Wi-Fi 5;
• 📡 TP-Link RE605X — for large houses up to 120 m²);
• 📡 Keenetic Plus – with Mesh support.

How to set up:

1. Connect the repeater to the outlet next to the router.
2. On the phone, connect to the repeater network (the name is indicated on the box).
3. Follow the instructions in the manufacturer’s app (e.g. Mi Home for Xiaomi).

5.2 Replace router antennas

If your router has removable antennas, you can replace them with more powerful antennas.

• 📶 7–9 dBi amplification antennas (for 2.4 GHz);
• 📶 Directed antennas (if the phone is always in the same room).

⚠️ Note: Installation of antennas with amplification greater than 9 dBi may violate the law (in some countries, a license for high-power transmitters is required).

5.3. Use the Mesh system.

If you have a large house (100)+ m2, a regular repeater won't help -- you need a Mesh network:

• 🏠 Xiaomi Mesh System (2 packages of 2-3 modules);
• 🏠 ASUS ZenWiFi - for gamers;
• 🏠 TP-Link Deco – Simple setup.

6. Check the phone for hardware problems

If none of these things worked, it might be the hardware of the phone that's to blame.

• 🔋 Problems with the antenna module (especially after falls);
• 🔌 Contact oxidation (if the phone has been in a wet environment);
• 📱 Wi-Fi chip malfunction (found on Redmi Note) 8/9 post-fix).

How to diagnose:

1. Check if your phone catches Wi-Fi in airplane mode (turn it on for 30 seconds, then turn it off).
2. Connect to another network (such as a coffee shop or friends’).
3. Test a phone with an access point on another device (e.g., give away Wi-Fi from a laptop).

If the problem persists, bring the phone to the service. Repair of the antenna module on Xiaomi costs from 1,500 to 3,000 rubles (depending on the model).

💡

If Wi-Fi only works near the router (1-2 meters), and disappears at a distance, the antenna of the phone is 90% to blame.

7. Alternative solutions for critical cases

If boosting Wi-Fi doesn’t help, consider drastic measures:

7.1. Go to mobile Internet

If you have unlimited fare (for example, Tele2 or MTS), turn on the modem mode:

1. Settings → Access Point and modem → Modem mode.
2. Connect your phone to a PC or other device USB.

7.2.Use Powerline adapters

These devices are wiring the Internet, and you plug one adapter into the router, another into the socket next to the phone, and you connect via cable or Wi-Fi.

• ⚡ TP-Link AV600 — budgetary;
• ⚡ Xiaomi Mi Powerline – Wi-Fi support.

7.3.Buy an external Wi-Fi adapter

For Xiaomi with support USB OTG You can connect an external adapter (for example, TP-Link) TL-WN725N). This is a rare solution, but sometimes it saves.
