Wi-Fi connectivity problems on Xiaomi smartphones are one of the most common problems faced by Redmi, POCO and Mi users. Symptoms can vary: the phone does not see the network at all, connects but without Internet access, constantly breaks the connection or requires re-entering a password. 80% of cases are not hardware breakdowns, but software failures or incorrect settings.
In this article, we’ll look at all the possible reasons Xiaomi isn’t connecting to Wi-Fi, from the trivial (like a module that’s disabled in settings) to the complex (antenna damage or IP conflict). Each solution is tested on models from 2020 to 2026, including the Redmi Note 12 Pro+, POCO F5 and Xiaomi 14. If you’ve tried rebooting your phone and router, skip the first section and go to the diagnostics.
Before you start checking, make sure that the problem is your smartphone: try connecting another device (laptop, tablet) to the same Wi-Fi. If the Internet works, read on. If not, the problem is in the router or the provider.
Basic checks: what to do first
Start with basic steps that often solve a problem in 1-2 minutes.These steps are relevant for all Xiaomi models, including the budget Redmi A2+ and flagship Xiaomi 13 Ultra.
✅ Reboot your smartphone and router. Turn off your phone for 30 seconds, then turn off the router for 1 minute. This will reset the network cache and eliminate temporary Wi-Fi module failures.
✅ Check flight mode. Sometimes users accidentally activate it through a notification curtain or a button on the case (on some models). POCO). Open the Quick Settings panel and make sure the aircraft icon is not highlighted.
✅ Make sure the Wi-Fi is on. Go to Settings. → Wi-Fi and switch the slider to "On." On some firmware (MIUI 14+) The module can be turned off automatically to save charge.
- 🔄 Wi-Fi Network Reset: In the Settings Menu → Wi-Fi tap your network name, select “Forget Network,” then connect again by entering the password.
- 📶 Range Check: If the router is running in two bands (2.4GHz and 5GHz), try connecting to each individually.Some older Xiaomi models (like Redmi) 4X) Not supported by 5 GHz.
- 🔋 Energy saving: In Settings → Battery → Power Saving Mode disable the "Background Limitation" option. It can block network connections.
⚠️ Attention, if after a network reset, the phone asks for a password but doesn't connect, check if it's entered with an error. MIUI Password symbols are displayed by dots, and it is easy to miss a typo.
2.Router problems: 5 settings that interfere with the connection
The router is not the phone, it's the router, 30 percent of the time, especially if other devices are also having trouble connecting, and consider the typical router settings that are in conflict with Xiaomi.
🔒 Type of encryption: Xiaomi smartphones do not support outdated security standards (e.g., encryption, WEP or TKIP). The best option — WPA2-PSK (or WPA3 For new models, change:
- Go to the router’s web interface (usually at 192.168.0.1 or 192.168.1.1).
- Go to the Wi-Fi section → Security settings.
- Select WPA2-PSK and save the changes.
📡 Wi-Fi channel. If the router is running on a congested channel (for example, 6 or 11 in the 2.4 GHz band), the phone may lose connection. Use utilities like Wi-Fi Analyzer (Android) to find the free channel, and install it manually.
| Problem. | Symptoms on Xiaomi | Decision |
|---|---|---|
| Incompatible encryption standard | The phone sees the network but does not connect ("Save", "Authentication") | Change WEP/TKIP to WPA2-PSK in router settings |
| The hidden network (SSID) | The network is not listed, but is manually connected. | Disable the “Hide SSID” option or add the network manually on your phone |
| Filtration by MAC-address | The connection is blocked with the message “No Internet” | Turn off filtering or add the phone’s MAC to the whitelist |
⚠️ Attention! If the phone still doesn't connect after changing the router settings, reset the network on your smartphone (Settings) → Wi-Fi → Additionally. → Resetting Wi-Fi settings. This will delete all saved passwords.
💡
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 you determine more quickly what range of the problem is.
3. Software failures: When MIUI is to blame
MIUI is known for its features that sometimes break the stability of Wi-Fi. Let's look at the most common bugs and how to fix them.
🛠️ Network resets: It's a radical but effective method that solves 90 percent of software problems:
Settings → About phone → Resetting → Resetting Wi-Fi, mobile network and Bluetooth settingsOnce reset, the phone will reboot and all the saved networks will be deleted, a method that is especially relevant after the MIUI update, when new settings conflict with old ones.
📱 Conflict with energy-saving functions. MIUI There are hidden settings that limit the Wi-Fi in the background:
- Go to Settings → Battery → Energy Saving Mode.
- Turn off the "Background Limitation" option.
- Go to Settings → Applications → Application Management → Three Points (menu) → Special Access → Battery Optimization.
- Find apps that use Wi-Fi (like YouTube, Telegram) and select “No Limits.”
- 🔄 Update MIUI: Check for updates in Settings → The phone. → System updates: Newer versions often fix Wi-Fi bugs.
- 📲 Cache Cleanup: Go to Settings → Annexes → Application management → Three points. → Show system, find “Wi-Fi settings” and clear the cache.
- 🚫 Shutdown VPN: If you use VPN (For example, Cloudflare WARP 1.1.1.1, temporarily deactivate it, it may block the connection.

4. Hardware malfunctions: when to carry in the service
If all the software methods have been tried, but Wi-Fi still doesn't work, the problem could be hardware.
📡 Wi-Fi antenna damage. Symptoms: phone doesn't see any network, even in places with strong signal. antenna can come off after falling or disassembling the body. Diagnosis:
- Try connecting to Wi-Fi in safe mode (press the power button → Safe Mode) If the network appears, the problem is in the software, if not in the antenna.
- Check if Bluetooth is working, and if it's not, it's probably a wireless module that's damaged.
🔌 Contact oxidation: If the phone was in a wet environment (like a bathtub or rain), the Wi-Fi module's contacts could oxidize. Signs: the network pops up, goes down, the Internet speed jumps.
🔋 Motherboard malfunction: In rare cases, the Wi-Fi controller on the board fails, and this is usually accompanied by other symptoms: the phone spontaneously reboots, does not charge or warms up.
⚠️ If you suspect a hardware breakdown, don’t disassemble the phone yourself, which can lead to a loss of warranty. In Xiaomi service centers, diagnostics take 15-30 minutes and are often free.

🌍 Problems with DNS. If websites don’t open, but YouTube or Telegram work, it’s your fault. DNS-The solution:
- In the same Wi-Fi settings, change the DNS to 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google).
- Or install 1.1.1.1: Faster Internet from Cloudflare.
🔄 If you had previously set up a proxy server (for example, to bypass locks), it could have stayed active:
Settings → Wi-Fi → Additional → Proxy server (should be “No”)💡
After the shift DNS The Internet has been working, the problem was the ISP's lockdown. DNS (1.1.1.1) for stable operation.
