Wi-Fi settings on Xiaomi smartphone: from connection to troubleshooting

Why Wi-Fi is important for Xiaomi

Modern Xiaomi smartphones based on MIUI offer ample opportunities for working with wireless networks, but not all users know how to set up Wi-Fi on their device as efficiently as possible. Proper connection depends not only on Internet speed, but also on the stability of messengers, streaming services and even battery autonomy. For example, improperly configured automatic connection to open networks can lead to a leak of personal data, and unoptimized energy saving parameters – to permanent connection breaks.

In this article, we will discuss not only the basic steps to connect to Wi-Fi, but also hidden functions. MIUI 14/15, We will focus on typical problems (for example, when a smartphone “sees” the network but does not connect) and how to solve them without resetting. Instructions are relevant for all modern models - from the budget Redmi Note 12 before the flagship Xiaomi 14 Ultra.

Basic Wi-Fi connection on Xiaomi: step-by-step instructions

Starting with the simplest, connecting to a home or office network, which is as simple as possible in MIUI, but there are a few things that can help you avoid errors, for example, if your router supports both frequencies (2.4 GHz and 5 GHz), your smartphone can automatically choose the less loaded, but not always the most stable.

To connect to Wi-Fi:

• 📱 Open Settings (cog icon on the home screen or in the application menu).
• 🌐 Select the Wi-Fi section – it’s usually located at the top of the menu.
• 🔍 Make sure the Wi-Fi slider at the top of the screen is active (lit in blue.
• 📋 In the list of available networks, find your name (SSID) and tap him.
• 🔐 Enter the password (if the network is secure) and click Connect.

After a successful connection, a tick will appear next to the network name, and in the status bar (at the top of the screen) a Wi-Fi icon with a signal level indicator. If the network is open (without a password), the smartphone can issue a warning about a potential danger, in which case it is better to refuse the connection or use a VPN.

Make sure the router is on and is giving a signal |

Check the correctness of the password entry (registrar is important!)|

Disable VPN if it is active |

Make sure that the router does not activate the “blacklist” of devices-->

Advanced Wi-Fi settings in MIUI: what can be optimized

Basic connectivity is often not enough for a comfortable work, and MIUI has several useful features that allow:

• 🔄 Automatically switch between 2.4 GHz and 5 GHz (if the router supports both frequencies).
• 📊 Limit background traffic for individual applications (good for battery savings).
• 🔒 Prioritize connection to certain networks.
• 🛡️ Enable notifications of suspicious networks (e.g., with substitution) DNS).

To open the extended settings:

1. Go to Settings. → Wi-Fi.
2. Tap the name of the already connected network (or click on the three dots in the upper right corner and select Additional Features).
3. Here you'll see options: Autoconnect - turns on/off automatic connection when a network is detected; Notify suspicious networks is useful for protection against phishing hotspots; Power saving Wi-Fi mode - turn off if you notice frequent connection breaks.

Note the bandwidth option (not available on all models). If your router supports 5 GHz but your smartphone is persistently connected to 2.4 GHz, try manually selecting your preferred frequency. This is especially true for the Xiaomi 13/14 series, where Wi-Fi 6/6E support allows you to achieve higher speeds.

Network Priority and Automatic Connection

If you move between multiple networks frequently (e.g., at home, work, and in a cafe), MIUI allows you to prioritize your connection, which eliminates the need to manually select the network each time, for example, you can make your smartphone always connect to your home network, ignoring less reliable open points.

To set the priority:

1. Open the Settings. → Wi-Fi.
2. Slip on the three dots in the upper right corner and select Additional Features → Network Priority.
3. Drag the networks in the right order (top priority).

You can also do this here:

• 🚫 Prohibit automatic connection to open networks (Out-of-Premise Option).
• 🔄 Enable notifications when new networks appear (good for travel).
• 📵 Disable connection to low signal networks (saves battery power).

If you notice that your smartphone is connecting to unfamiliar networks without your knowledge, check the Wi-Fi Direct and Hotspot 2.0 settings – sometimes these features can conflict with basic settings.

Optimizing the speed and stability of Wi-Fi on Xiaomi

Slow internet or frequent connection breakdowns are common problems that are not always associated with the provider, and the settings of the smartphone are often to blame.

If the problem persists, try changing it. DNS-servers:

1. Open the settings of the connected network.
2. Select Change Network → Additional → IP settings.
3. Set Static and enter DNS: 🌍 Google DNS: 8.8.8.8 and 8.8.4.4 🛡️ Cloudflare DNS: 1.1.1.1. and 1.0.0.1.

This can speed up page loading and reduce delays, especially if your ISP uses congested DNSs.

💡

If you have Xiaomi 13/14 with Wi-Fi 6 support, turn this option on in your router settings. For maximum speed, it is also recommended to use an 80 MHz or 160 MHz channel (configurable in the router control panel).

Solving typical Wi-Fi issues on Xiaomi

Even after you've set it up properly, there can be problems, and let's look at the most common scenarios and how to fix them.

1.The smartphone "sees" the network, but does not connect

Reasons:

• 🔑 Incorrect password (check register and symbols).
• 🔄 Incompatibility of standards (for example, the router works only on the basis of the 802.11ac, The smartphone only supports 802.11n).
• 🛡️ Lock-in MAC-router.

Decisions:

• Restart the router and smartphone.
• Remove the network from the saved (Settings → Wi-Fi → Tap over the network → Delete) and connect again.
• Check the router settings: disable the MAC filtering, change the encryption type to WPA2-PSK.

Permanent breaks of connection

The most common fault is the power saving mode.

1. Settings → Battery and performance → Energy saving mode.
2. Choose Performance or turn off optimization for Wi-Fi.

3. Low speed with good signal

The problem could be an overloaded router channel.

• Change the channel in the router settings (for example, from automatic to fixed 6 or 11 for 2.4 GHz).
• Disable Qos or Band Steering on the router (sometimes these features conflict with smartphones).

💡

If the Wi-Fi problem has occurred after the MIUI update, try rolling back to the previous firmware version or wait for a patch. Network bugs are often fixed in the next updates.

Wi-Fi security on Xiaomi: how to protect your data

Open networks in cafes, airports or hotels are convenient but carry risks, from traffic interception to phishing attacks. MIUI offers several tools to protect:

• 🛡️ VPN: Turn on the built-in. VPN (if available, or install a reliable application (e.g. ProtonVPN).
• 🔒 Protection against fake networks: Enable the option to Notify suspicious networks in Wi-Fi settings.
• 📵 Background Traffic Limitation: Turn off automatic app updates in the background via Settings → Annexes → Autoboot.
• 🔄 Use of private use DNS: Configure 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) for encryption DNS-request.

If you are frequently connected to public networks, consider using a second user profile (available on some Xiaomi models with MIUI 14+) to isolate personal data from potentially dangerous connections.

⚠️ Note: Never connect to networks with names like this. Free_WiFi, Starbucks_Free or Airport_Public Attackers often create fake hotspots with similar names to intercept data.

Resetting Wi-Fi settings: when it is needed and how to do it

If all attempts to set up Wi-Fi fail, the last option is to reset the network settings, which will delete all stored networks, passwords and connection settings, returning them to factory data. Personal data (photos, contacts, applications) is not affected.

For discharge:

1. Open Settings → System → Resetting settings.
2. Select Reset Wi-Fi, Mobile Network and Bluetooth settings.
3. Confirm the action (it may be necessary to enter) PIN-code-key).

After discharge:

• 🔄 The smartphone will reboot.
• 📋 All saved networks will be deleted – you will have to connect again.
• 🔧 Settings VPN, Modem and Bluetooth will also drop.

⚠️ Note: If the problem persists after the reset, it may indicate a hardware failure (such as a Wi-Fi module malfunction).In this case, contact the Xiaomi service center. 10/11 and older, such cases are extremely rare, but are possible after falls or moisture.
