This problem is familiar to many owners of smartphones of the Redmi Note, Redmi A or flagship models like Redmi K50The reasons may lie in the phone's settings, router problems, or even firmware issues. MIUI.

In this article we will look at 10 most common reasons, Why Redmi Wi-Fi won't connect—from trivial password errors to hidden bugs in wireless module drivers. You'll learn how to diagnose the problem, which settings to check first, and what to do if standard methods don't help. And at the end, you'll find FAQ with answers to frequently asked questions and tips for preventing similar failures in the future.

1. Check the obvious: password, airplane mode, and geofences

Start with the simplest things—sometimes the problem lies in the little things that users don't notice. For example, airplane mode can be activated randomly (or according to a schedule in MIUI). Check the top notification bar: if the airplane icon is highlighted, tap it to turn it off.

• 🔄 Switch your keyboard layout to English — sometimes passwords are case-sensitive.
• 📱 Make sure the feature is not enabled Hide password (eye in the input field).

Also check if your location is affected by geoblocking (Applicable to some public networks at airports or hotels). If you've recently traveled, the network may require re-authentication.

2. Reset network settings: when the phone "forgets" Wi-Fi

If Redmi I used to connect to this network, but now it stubbornly ignores it. The problem may be in cached settings. System MIUI Sometimes it saves outdated settings (such as IP address or authentication data), which leads to conflicts. To reset them:

Write down your VPN settings (if you use one)

Disable SIM card (optional)

Connect to mobile internet to check-->

Attention! After the reset, you will have to re-enter passwords for all saved networks, including mobile Internet (if you use 4G/5G with manual APN settings).

3. Router issues: channel, encryption, and DHCP

In 30% of cases, it is not the phone that is to blame, but routerThis is especially true if other devices (laptop, tablet) are also experiencing connection issues. Check the following settings:

If your router is in the mode 802.11b/g, some models Redmi (especially new ones) may refuse to connect due to incompatibility. Also causing problems WEP encryption - it is outdated and not supported by modern versions Android.

What to do if the router is not yours?

If you are connecting to someone else's network (for example, in a cafe or hotel), try:

2. Restart your phone – sometimes changing the IP address helps.

3. Try connecting through a browser (some networks require authorization on the portal).

⚠️ Attention: If you change the router settings, after saving the parameters Be sure to reboot it (Unplug the power cord for 30 seconds.) Many changes only take effect after a full restart.

4. MIUI Crashes: Cache, Updates, and Safe Mode

Firmware MIUI It's known for its quirks, but sometimes they interfere with normal operation. If Wi-Fi doesn't connect after a system update, try the following steps:

Clearing the Wi-Fi module cache:

1. Go to Settings → Applications → Manage applications.
2. Click on the three dots in the upper right corner and select Show system.
3. Find Wi-Fi (or WifiService), open and press Clear cache.

If the network works in Safe Mode, one of your installed applications is to blame. Remove suspicious programs (especially those requesting network or VPN access).

5. Hardware problems: antenna, Wi-Fi module and physical damage

If none of the software methods helped, it might be because hardware failureTypical signs:

• 📶 The phone doesn't detect it not a single network (even with Wi-Fi turned on).
• 🔌 The connection is interrupted at the slightest movement of the phone (antenna problem).
• 🔥 The phone overheats in the upper part of the case (the Wi-Fi module may be damaged).

Check the functionality of the module using equipment test:

1. Dial in your phone app ##4636##.
2. Select Phone information.
3. Scroll down to the block Wi-Fi and check the status. If there Disabled or error, the module is faulty.

Critical information: If the phone has been dropped or exposed to water, there's a high risk of the antenna contact becoming detached. In this case, repair at a service center is the only solution.

6. IP address conflicts and manual network settings

Sometimes Redmi can't get an IP address from the router due to a DHCP conflict. This manifests itself as the network being saved as "Connected, no internet access." The solution is to assign static IP:

1. Go to Settings → Wi-Fi, click on the problematic network.
2. Select Change network → Advanced settings.
3. In the field IP settings select Static.
4. Enter an IP address from your network range (e.g. 192.168.1.100, if the router has 192.168.1.1).
5. Please specify gateway (192.168.1.1), subnet mask (255.255.255.0) and DNS (for example, 8.8.8.8 for Google).

If you are unsure about the settings, use alternative DNS:

• 🌍 Google DNS: 8.8.8.8 And 8.8.4.4
• 🌍 Cloudflare DNS: 1.1.1.1 And 1.0.0.1

7. Firmware issues: rollback, custom ROMs, and kernel

Updates MIUI Wi-Fi sometimes crashes. If the problems started after an update, try:

Rollback to a previous version:

• 🔄 Download the old firmware from the official website Xiaomi (chapter Download → Archive).
• 📱 Go to Settings → About phone → System update.
• 🔧 Click on the three dots at the top and select Select firmware file.

Installing custom firmware: If the official methods don't help, some users solve the problem by switching to AOSP- firmware (for example, LineageOS or Pixel Experience). However, this requires unlocking the bootloader and may void the warranty.

   adb shell dumpsys wifi

3. Look for lines with errors (eg. ERROR or FAILED).

Service codes for diagnostics:

• 📡 ##232338## — Wi-Fi module test.
• 📶 ##4636## → Wi-Fi information — detailed connection information.
• 🔄 ##7262626## — wireless module test (on some models).

Factory reset: A last resort if all else fails. Before doing this, be sure to:

• 🔐 Save the data to Google Drive or your computer.
• 📝 Write down your account passwords (they will be deleted).
• 🔧 Go to Settings → Advanced → Backup & reset → Factory data reset.
