How to Improve Wi-Fi on Xiaomi Phone: From Simple Settings to Hidden Features MIUI

The weak Wi-Fi signal on Xiaomi is a problem that one in three users encounter, and it's hanging on social media, YouTube videos are loading forever, and the connection is missing in another room, and it can be caused by the settings of the phone, the router, or even physical obstacles, but the good news is that 90% of the time, you can fix it without buying new hardware.

In this article, we’ll look at all the possible ways to improve Wi-Fi on Xiaomi, from basic actions like rebooting your router to hidden features. MIUI, And we're going to focus on the Redmi Note models, which even the most experienced users don't know about. 12/13, POCO X5 mi 11/12, But the instructions are for any smartphone brand, you will also learn how to check the real speed of the connection (not what the operator shows), and which applications will help diagnose the problem.

Before you start setting up, make sure that the problem is in the phone. Try connecting another device to the same network (laptop, tablet). If the speed is normal, it is Xiaomi's fault. If it slows everywhere, it is the router or the provider. In the latter case, first call in support of the ISP and check if there are problems on their side.

Why Wi-Fi is not working well on Xiaomi: 5 main reasons

Before you fix something, you need to understand the root of the problem, and here are the most common reasons for weak signal or connection breaks on Xiaomi smartphones:

1.Outdated firmware or errors MIUI.

Xiaomi regularly releases updates that fix bugs in the Wi-Fi module. If you haven't updated your phone in a long time, chances are that the problem lies in the software. 9/10 and POCO M3, where MIUI 12 There were massive complaints about communication breaks.

2. Incorrect router settings.

Many users do not even know that their router is running on an outdated standard. 802.11n modern 802.11ac/ax, Or that you have power saving mode on, which limits the signal power, and you can also have problems with conflicting Wi-Fi channels if you have many neighbors with routers in your home.

3. Hardware limitations of the phone.

Cheap Redmi models (e.g. Redmi) A1 or POCO C31) They are often equipped with weak Wi-Fi modules that cannot physically provide a stable connection over long distances, in which case only an external signal amplifier or replacing the router with a more powerful one will help.

4. Network overload.

If more than 10 devices (smartphones, smart appliances, laptops) are connected to a single router, the speed can sag even at a high tariff bar, especially on Xiaomi’s budget models, where the processor is not optimized to handle a large number of network requests.

5. External interference.

Concrete walls, metal structures, microwave ovens, and even aquariums can weaken the signal, and if the phone catches Wi-Fi well in one room and poorly in another, the problem is likely physical obstacles.

Update firmware and reset network settings

So let's start with the simplest and most effective method, which is to update the system. MIUI Often there are patches that fix bugs with Wi-Fi, so first check the relevance of the firmware:

How to update MIUI:

1. Open Settings → About the phone → System update.
2. Click Check for updates.
3. If a new version is available, download it and install it.

If there are no updates or the problem persists, try resetting your network settings, which will delete all stored Wi-Fi and Bluetooth networks, but often helps with unstable connections:

1. Go to Settings. → SIM-maps and mobile networks → Resetting network settings.
2. Confirm the action.
3. Restart your phone and connect to Wi-Fi again.

💡

If Wi-Fi is getting worse after the update, try rolling back to the previous version. MIUI Fastboot. The instructions are on the forum. 4PDA model-themed.

Optimizing router settings for Xiaomi

If the problem isn't with the phone, it's time to look at the router's settings. Most users never change the default settings, and it's a waste of time that the right configuration can increase the speed and stability of the connection in the network. 2-3 once.

Key parameters for change:

• 📶 Wi-Fi Standard: Install 802.11ac (or 802.11ax, If the router supports Wi-Fi 6, old standards like 802.11n They work slower and less stable.
• 🔄 Channel and width: Select the channel with the least interference (use the Wi-Fi Analyzer app for analysis). Channel width set to 40 MHz (or 80 MHz if the router supports).
• 🔒 Type of security: Use WPA2-PSK or WPA3-PSK. Obsolete. WEP Not only is it unsafe, it also slows down the connection.
• 📡 Transmission power: In some routers (e.g. TP-Link or ASUS) You can increase the signal power to 100 percent. Look for this parameter in the Wireless section. → Advanced.

How to enter the settings of the router:

Usually it is enough to enter in the address bar of the browser 192.168.0.1 or 192.168.1.1 (Login and password by default often admin/admin If you don't, use your router's official app (e.g. Mi Wi-Fi for Xiaomi devices).

💡

If your router supports dual-band Wi-Fi (2.4 GHz and 5 GHz), always connect to a 5 GHz network - it is less loaded and faster. On Xiaomi, this is done in the network selection menu (two networks with the same name but different frequencies should be displayed).

Hidden functions MIUI to improve Wi-Fi

Xiaomi adds to its shell MIUI There are a few hidden features that can make Wi-Fi work better, and most people don't know about them, but they actually work.

1. High-performance Wi-Fi mode

This feature is forced to turn on the maximum power of the Wi-Fi module, but can drain the battery a little faster.

1. Open the Settings. → Wi-Fi.
2. Tap your network name and select Change Network.
3. Turn on the switch High Performance Mode (some models called Improved Wi-Fi).

2. disable automatic switching to mobile data

By default. MIUI It can switch to the mobile Internet if the Wi-Fi signal is weak, which is useful, but sometimes leads to unnecessary breaks, to turn off the signal:

1. Go to Settings. → SIM-maps and mobile networks → Switching to mobile data.
2. Turn off the automatic switching option.

3.Tune in. DNS speed up the Internet

Sometimes slow Wi-Fi is not about signal, but about slow Wi-Fi. DNS-ISP servers. Try using public ones. DNS from Google or Cloudflare:

1. Press the name of your Wi-Fi network in the settings and select Change Network → Additional settings.
2. In the field DNS Type: 8.8.8.8, 8.8.4.4 (Google) or 1.1.1.1, 1.0.0.1 (Cloudflare).
3. Save the changes and reconnect to the network.

Use of third-party applications for diagnosis

If standard methods don’t work, it’s time to use specialized utilities to help identify weaknesses in your network and offer solutions.

Top.-3 Applications for Wi-Fi Analysis on Xiaomi:

• 📊 Wi-Fi Analyzer (from farproc) - shows the load of channels, signal power and helps to choose the optimal channel for the router.
• 📈 Internet Speed Meter – displays the real download/return speed in the notification panel so you can track drawdowns.
• 🔍 NetSpot – builds a heat map of the signal in your home, showing areas with poor coverage.

How to use Wi-Fi Analyzer:

1. Install the app from Google Play.
2. Open it and go to the Channel Graph tab.
3. See which channels are less loaded (usually 1, 6 or 11 for 2.4 GHz).
4. Go to the router settings and change the channel to free.

Example of analysis:

Let’s say the app shows that your router is running on a channel. 6, And the neighbors use it, too. 1 or 11 — This can improve speed immediately. 30-50%.

✅ Make sure the problem is not on the provider’s side (call for support)

✅ Restart the router (turn off the socket for 30 seconds)

✅ Check the speed on another device (laptop, tablet)

✅ Install one of the diagnostic applications (Wi-Fi Analyzer or NetSpot)

Hardware solutions: amplifiers and Mesh-systems

If the software methods didn't work, maybe the problem is the physical limitations, and then you can use the following:

1. Wi-Fi repeaters (repeaters)

Devices like Xiaomi Mi Wi-Fi Repeater 2 or TP-Link RE605X They amplify the signal and expand the coverage, and you just plug them into the low signal area and connect them to the main network. 30-50% due to double data transmission.

2. Mesh systems

More advanced solution for large apartments or houses. Systems like Xiaomi Mi Mesh Router AX3000 Or Google Nest Wi-Fi creates a single network of multiple access points that the phone automatically switches between, which is more expensive than a repeater, but more reliable and faster.

3. External antennas for router

If your router supports removable antennas, you can buy more powerful ones (for example, with amplification). 9 This will increase the range of action by 20-40%.

4. The 5GHz transition

If your router is dual-band, but the phone is stubbornly clinging to 2.4 GHz, try manually connecting to a 5 GHz network.

1. Forget the current network in the Wi-Fi settings.
2. In the list of available networks find the same, but with a note 5G or 5 GHz.
3. Connect to it (the password is usually the same).

💡

If you live in an apartment building, try changing the name of the network (SSID) Sometimes Xiaomi phones get confused if they see many networks with the same or similar names (for example, the same name, "TP-Link_123" and "TP-Link_124").

Frequent Mistakes of Xiaomi Users When Setup Wi-Fi

Many of them degrade their signal without even knowing it, and here are the most common mistakes and how to avoid them:

1. Automatic channel selection

Auto in the router settings does not always choose the optimal channel; it is better to manually specify the free channel (see the section on Wi-Fi Analyzer).

2. Hiding SSID

Some users turn off the broadcast of the network name (SSID), Thinking it will improve security, actually it only makes it harder to connect and can cause problems with auto-connection on Xiaomi.

3. Use of outdated safety standards

If it's on the router. WEP or WPA, swap for WPA2-PSK or WPA3-PSK. Older standards are not only unsafe, they slow down connection.

4. Place the router in an uncomfortable place

Do not put the router in a closed cabinet, behind the TV or near metal objects. The optimal place is on a table or wall in the center of the apartment.

5. Ignoring router updates

Like a phone, a router needs to update its firmware. Go to its settings and check if it's up to date.

💡

If after all the manipulations of Wi-Fi on Xiaomi still works poorly, try to connect the phone to the router via cable through the phone. USB-OTG (If the cable speed is normal, the problem is exactly in the phone's Wi-Fi module or antenna.

⚠️ Note: Some Xiaomi models (e.g. Redmi Note) 8 pro POCO F1) post-update MIUI 13/14 There's a bug with a constant cliff of Wi-Fi, and the solution is to roll back. MIUI 12.5 Or wait for a patch from Xiaomi.
