The Redmi Note 11 is one of Xiaomi’s most popular budget smartphones — reliable, powerful, and packed with MIUI and HyperOS features. However, some users experience a frustrating issue: Wi-Fi disconnects automatically, or the phone won’t connect to Wi-Fi at all.

If you’re facing the “Redmi Note 11 no Wi-Fi” problem, don’t worry. In this detailed guide, we’ll explain why it happens and walk you through tested solutions to fix Wi-Fi disconnection, authentication errors, or weak signal issues on your Redmi Note 11.

📶 Why Wi-Fi Problems Happen on Redmi Note 11

Before jumping into the fixes, it helps to understand what might be causing your Redmi Note 11’s Wi-Fi issues. The problem usually originates from one of the following:

  1. Network misconfiguration – Saved Wi-Fi credentials or IP settings may conflict with your router.

  2. MIUI/HyperOS settings – Some features, like “Wi-Fi Assistant,” automatically switch between mobile data and Wi-Fi, causing disconnections.

  3. Software bugs or outdated firmware – Certain MIUI or HyperOS builds may contain Wi-Fi-related glitches.

  4. Power-saving or optimization settings – Xiaomi’s battery optimization can limit Wi-Fi when the screen is off.

  5. Hardware damage – Rarely, antenna or Wi-Fi module damage may cause weak or lost connections.

Let’s go step-by-step to identify and fix the issue.

🧭 Step 1: Restart and Refresh Network Connections

The simplest step often fixes the issue immediately.

  1. Restart your Redmi Note 11.
    Hold the Power button → Tap Restart.

  2. Restart your router/modem.
    Turn it off for 30 seconds, then power it on again.

Once both are rebooted, reconnect to Wi-Fi and check if the connection is stable.
If not, continue with the next step.

⚙️ Step 2: Forget and Reconnect to the Wi-Fi Network

Sometimes stored network settings cause connectivity errors.

  1. Open Settings → Wi-Fi.

  2. Tap your Wi-Fi network name.

  3. Select Forget network.

  4. Reconnect by entering your password again.

This refreshes the network configuration and clears outdated IP or DNS information.

🧩 Step 3: Disable “Wi-Fi Assistant” to Prevent Auto-Switching

One of the most common reasons Redmi devices disconnect from Wi-Fi automatically is Wi-Fi Assistant — a feature designed to switch between mobile data and Wi-Fi depending on signal quality.

To turn it off:

  1. Go to Settings → Wi-Fi.

  2. Tap Wi-Fi Assistant (or Additional Settings under Wi-Fi).

  3. Disable:

    • Automatically select best networks

    • Switch to mobile data automatically

This ensures your Redmi Note 11 remains connected to Wi-Fi even when the signal weakens slightly.

⚡ Step 4: Turn Off Battery Saver or Power Optimization

MIUI’s aggressive battery-saving algorithms can limit background Wi-Fi activity to extend battery life — especially when your screen is off.

To fix this:

  1. Open Settings → Battery → Battery Saver.

  2. Tap Battery Saver on apps.

  3. Find your Wi-Fi or Settings app.

  4. Set No restrictions.

Additionally, disable Ultra Battery Saver if it’s on — this mode disables Wi-Fi in the background by default.

🧼 Step 5: Clear Wi-Fi System Cache and Data

Clearing the system cache helps remove corrupted temporary files that may interfere with Wi-Fi functions.

Here’s how:

  1. Open Settings → Apps → Manage Apps.

  2. Tap the three-dot menu (⋮) → Show all apps.

  3. Search for Wi-Fi or WLAN.

  4. Tap it → Clear Data → Clear Cache.

Then reboot your device and reconnect to your Wi-Fi network.

🌐 Step 6: Reset Network Settings

If your Wi-Fi still fails to connect, it’s time to reset all network configurations. This will not delete your personal data, but it will remove all saved Wi-Fi, Bluetooth, and mobile network settings.

Steps:

  1. Go to Settings → Connection & Sharing (or Additional Settings, depending on your MIUI version).

  2. Tap Reset Wi-Fi, Mobile Networks, and Bluetooth.

  3. Confirm the reset.

After reboot, connect to your Wi-Fi again and test the stability.

🧠 Step 7: Check for System Updates

Xiaomi regularly releases MIUI or HyperOS updates that fix known connectivity bugs.

To check for updates:

  1. Open Settings → About Phone.

  2. Tap System Update.

  3. If an update is available, download and install it.

After updating, restart your device and check your Wi-Fi again.

🔧 Step 8: Change DNS Settings (Optional)

Sometimes, the issue isn’t with the phone but with your network’s DNS server. Switching to a public DNS like Google or Cloudflare can improve connection reliability.

To change DNS manually:

  1. Open Settings → Wi-Fi.

  2. Tap your connected Wi-Fi network.

  3. Choose Modify network → Advanced options.

  4. Change IP settings to Static.

  5. Set:

    • DNS 1: 8.8.8.8

    • DNS 2: 8.8.4.4

Save changes and reconnect.

📱 Step 9: Disable Dual Apps Feature (If Enabled)

Another known cause of “Wi-Fi disconnects on Redmi” is MIUI’s Dual Apps feature. It sometimes conflicts with Google Play Services, which affects network stability.

To fix this:

  1. Go to Settings → Apps → Dual Apps.

  2. Tap the gear icon in the upper-right corner.

  3. Select Delete Dual App Accounts.

  4. Restart your device.

If Wi-Fi works properly afterward, you can recreate Dual Apps later if needed.

🧰 Step 10: Perform a Factory Reset (Last Resort)

If none of the previous methods work, a factory reset might be necessary. This step resolves deeper software bugs but erases all your data — so back up your files first.

To factory reset your Redmi Note 11:

  1. Open Settings → About Phone → Factory Reset.

  2. Tap Erase all data.

  3. Confirm and wait for the process to finish.

Once completed, set up your phone from scratch and test Wi-Fi connectivity again.

🛰️ Step 11: Check for Hardware or Router Issues

If Wi-Fi still doesn’t work after a full reset, try the following:

  • Test other devices on the same Wi-Fi network.

    • If they also fail, the problem is with your router.

  • Connect your Redmi Note 11 to a different Wi-Fi network (like a friend’s or public hotspot).

    • If it connects successfully elsewhere, your router may have a compatibility issue.

If the issue persists everywhere, the Wi-Fi antenna or chip in your Redmi Note 11 may be faulty — contact Xiaomi Support or visit an authorized service center.

💡 Additional Tips for Stable Wi-Fi on Redmi Note 11

  • Keep Bluetooth turned off when not in use (Bluetooth can interfere with 2.4GHz Wi-Fi).

  • Place your router in an open space — avoid metal objects or thick walls.

  • Regularly reboot your router for better performance.

  • Use the 5GHz band instead of 2.4GHz if your router supports it.

  • Avoid VPN or proxy apps that may block Wi-Fi traffic.


🧾 Final Thoughts

The “Redmi Note 11 no Wi-Fi” issue is common but usually caused by a simple software misconfiguration or system feature. Disabling “Wi-Fi Assistant,” updating MIUI, and resetting network settings solve the problem for most users.

However, if none of the steps above help, it could be a hardware-related fault requiring professional inspection.

With these fixes, you should be able to restore a stable Wi-Fi connection on your Redmi Note 11 and enjoy uninterrupted browsing, streaming, and gaming again.
