Why Xiaomi has Wi-Fi but no internet access: a full analysis of the reasons and solutions

You open up the Xiaomi Redmi Note 12 or POCO X5 Pro, you see the familiar Wi-Fi icon in the status bar, but the browser stubbornly gives out "No Internet connection," and messengers do not update. The situation is familiar? Network connection is there, but traffic is not going — one of the most common problems on Xiaomi smartphones, and the reasons for it can be as many as a dozen, from banal errors in the router settings to hardware failures in the Wi-Fi module.

In this article, we’ll look at all the possible reasons why your Xiaomi “sees” the network but can’t get online, from simple (incorrect DNS) to complex (antenna damage). For each cause, we’ll give you a step-by-step solution with screenshots from MIUI 14 and HyperOS, and how to tell the difference between a software failure and a hardware defect. If the problem persists after reading, you’ll end up with an FAQ answering typical questions and a checklist for diagnosis.

1.Router-side issues: Why other devices work and Xiaomi doesn't

The first thing to check is whether the router is to blame. Often, Xiaomi’s smartphone “refuses” to work with the Internet due to the specific settings of the router that other devices (laptops, TVs) ignore.

• 🔄 Reboot router: turn it off the socket for 30 seconds. DHCP and temporary lockdowns.
• 📡 Wi-Fi mode: if the router is configured to 802.11r (Fast Transition or 802.11k/v, Some Xiaomi models, especially MIUI 12-13) They may not connect properly.
• 🔒 Filtration MAC-Addresses: In the router settings, a “white list” of devices can be enabled where MAC Your Xiaomi is missing.
• 🌐 DNS-servers: if the router distributes incorrect DNS (For example, from the provider, the smartphone will not be able to allow domain names.

How to check:

1. Connect another device (laptop, tablet) to the same Wi-Fi, and if the Internet works, the problem is with Xiaomi's settings.
2. Go to the router control panel (usually at 192.168.0.1 or 192.168.1.1) and check:

⚠️ Note: If the router is dual-band (2.4 GHz + 5 GHz, try connecting to the network with another suffix (e.g, MyWiFi_5G Some Xiaomi models don't work well with channels 5 GHz 100.

2. Misconfigured network settings on Xiaomi: what to check first

If the router is fine and the internet is still missing on Xiaomi, it's time to dig into the smartphone settings, and let's start with the obvious: connectivity settings.

Open Settings → Wi-Fi, tap your network name and check:

• 📱 IP-address: 169.254.x.x — that means DHCP failed to give the correct IP. Click on “Forget the Network” and connect again.
• 🔄 Proxy: MIUI Sometimes the proxy will spontaneously turn on (especially after updates). → Wi-Fi → Additionally. → proxy.
• 🌍 DNS: by default, the smartphone takes DNS You can use the router to lock them down. Try manually writing 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

If the Internet does not work after the changes, reset the network settings:

Settings → Memory and Network → Network Reset → Reset your Wi-Fi, mobile network and Bluetooth settings

A tap called Wi-Fi. → Check it out. IP-address

Disable Proxies in Additional Settings

Manually prescribe DNS (8.8.8.8)

Reset the network settings

Reboot your smartphone-->

3. Conflict IP-Why Xiaomi is getting a “grey” address» IP

One of the most insidious causes is conflict. IP-This happens when two devices receive the same address on the local network. IP from a router or when Xiaomi cannot get IP generally (remains with) 169.254.x.x).

How to fix it:

1. Forced IP update: Forget the network in the Wi-Fi settings. Turn on Flight Mode for 10 seconds, then turn off. Connect to Wi-Fi again.

Reserve IP for Xiaomi in the router

• Find it. MAC-Address of your smartphone in Settings → The phone. → General information → MAC-Wi-Fi address.
• In the router bar, go to DHCP → Address Reservation and link the MAC to a fixed IP (e.g., 192.168.0.100).

💡

If the problem persists after backing up the IP, try manually prescribing IP on your smartphone: in the Wi-Fi settings, select “Static IP” and specify an address from your network range (for example, 192.168.0.150), a mask 255.255.255.0 and a gateway 192.168.0.1.

4. firmware failures: MIUI and HyperOS bugs that break Wi-Fi

Software bugs are a scourge of Xiaomi smartphones, especially after the updates, and MIUI 14 and HyperOS have been detected bugs that caused Wi-Fi to connect but the Internet to fail.

• 🐞 Bug with IPv6: included in some regions IPv6 conflict IPv4, blockage.
• 🔄 Resetting settings after update: MIUI sometimes resets user-generated DNS proxy.
• 📱 Energy saving conflict: Aggressive battery optimization can turn off background traffic.

How to treat:

1. Turn off IPv6: Settings → Wi-Fi → Tap over the network → Additional → IPv6 → Disable
2. Reset your network settings (see Section 2).
3. Turn off the “Adaptive Battery”: Settings → Battery → Adaptive Battery → Disable
4. Update the firmware: check for updates in Settings → About phone → System update.

⚠️ Note: If the problem has occurred after the update MIUI/HyperOS, Try to retrace the previous version via Fastboot. 4PDA But remember, rollbacks can cause the bootloader to lock down!

5. Hardware malfunctions: When the Wi-Fi module is to blame

If none of the software methods worked, there is a risk that the problem is in the hardware.

• 📡 Wi-Fi antenna: Contacts break or are damaged after falling.
• 🔌 Module Wi-Fi/Bluetooth: It overheats or burns (typical for Redmi Notes) 8/9).
• 🔋 Power controller: does not give enough voltage to the communication module.

How to diagnose:

To check the antenna, you can use the engineering menu:

Enter the dialer in ##4636##


Go to Wi-Fi Information and see the Signal Level (RSSI).




If the value is below -70 dBm when you are near the router, the antenna problem is the problem.

💡

If your smartphone doesn’t see any Wi-Fi networks (even those nearby), there’s a 95% chance that you’re at fault for a hardware failure, and in this case, self-repair is not recommended — call the service.

6. Traffic Blocking: VPNs, firewalls and "smart" restrictions

Sometimes the Internet on Xiaomi is not working because of Wi-Fi, but because of the blocking of traffic at the system or application level.

• 🔒 VPN-clients: some VPN (for example, Turbo VPN or 1.1.1.1.) block traffic when the connection is broken.
• 🛡️ Firewalls: MIUI It has a built-in firewall that can block suspicious connections.
• 👶 Parental Controls: If your phone is enabled with Digital Well-Being, it may restrict access to the network.
• 📵 Mobile traffic restrictions: sometimes mobile internet settings are moved to Wi-Fi.

How to check:

1. Turn off the VPN in the notification panel.
2. Go to Settings → Apps → Permissions → Autorun and make sure browsers and instant messengers are not blocked.
3. Check Settings → Connections and Sharing → Traffic Savings – Turn off Wi-Fi restrictions.
4. In Settings → Special Opportunities → Digital Well-being, disable all restrictions.

💡

If you're using AdGuard or similar ad blockers, try temporarily disabling them. Sometimes they intercept. DNS-requests and breaks the connection.

7 Security Protocol Problems: Why Xiaomi Doesn't Like WPA3

Many modern routers support the new WPA3 security standard, but Xiaomi smartphones (especially on MIUI 12 and older) often conflict with it.

• The connection to the network is happening, but the Internet is not available.
• Constant password requests.
• The message “Authentication...” hangs endlessly.

Decision:

1. Go to the router settings and change the security type from WPA3 to WPA2-PSK.
2. If you want to leave WPA3, try turning on WPA2/WPA3 Transition compatibility.
3. On your smartphone in the Wi-Fi settings, turn off the option of Automatic Connection for this network.

⚠️ Note: If your router is using 802.11r (Fast Roaming, disable this feature – it is incompatible with most Xiaomi smartphones and causes connection breaks.
