🔍 Introduction

If your Redmi Note 13 is having trouble connecting to Wi-Fi, you’re not alone. Many Xiaomi, Redmi, and POCO users experience random disconnections, connection failures, or unstable Wi-Fi speeds — especially after software updates or router changes.

In this complete troubleshooting guide, we’ll explain why your Redmi Note 13 can’t connect to Wi-Fi, explore the main causes, and give you step-by-step solutions to fix the problem quickly and safely — without needing any third-party apps.

Whether you’re using MIUI 14 or HyperOS, these methods will help restore your internet connection in minutes.

⚠️ Common Wi-Fi Connection Problems on Redmi Note 13

Before jumping to solutions, it’s important to identify what kind of Wi-Fi issue you’re facing. Users commonly report:

  • Wi-Fi not connecting at all

  • Wi-Fi keeps disconnecting automatically

  • Wi-Fi connected but no internet access

  • The network doesn’t appear in the list

  • Wi-Fi works on other devices but not on Redmi Note 13

  • “Authentication problem” or “Saved, not connected” messages

Each of these has different causes — from router issues to MIUI/HyperOS settings — but don’t worry, we’ll cover all of them.

🧠 Why Your Redmi Note 13 Won’t Connect to Wi-Fi

Here are the most frequent reasons behind Wi-Fi connection failures on Redmi Note 13 devices:

  1. Incorrect Wi-Fi password or saved credentials

  2. Router or modem errors (overheating or software crash)

  3. Outdated system software or firmware bug

  4. Automatic network switching in MIUI/HyperOS settings

  5. Wi-Fi frequency mismatch (2.4GHz vs 5GHz)

  6. MAC address filtering or blocked device in router settings

  7. Corrupted Wi-Fi cache or configuration files

  8. Battery saver or power management restrictions

Now let’s go through each fix step-by-step.

🧩 Step 1: Restart Your Phone and Router

The first and simplest fix is often the most effective.

  • Restart your Redmi Note 13 by holding the power button → tap Restart.

  • Then unplug your router for at least 30 seconds and plug it back in.

This resets the IP configuration and clears temporary conflicts between the router and device.

🔄 Step 2: Forget and Reconnect to Wi-Fi

Sometimes saved network data becomes corrupted. Here’s how to reset it:

  1. Go to Settings → Wi-Fi.

  2. Tap the network you’re trying to connect to.

  3. Select Forget Network.

  4. Wait a few seconds, then reconnect by entering the password again.

💡 Tip: Double-check that Caps Lock or extra spaces aren’t entered in the password field.

📶 Step 3: Disable “Automatically Select Best Network”

MIUI and HyperOS have a setting called Wi-Fi Assistant, which can automatically switch between Wi-Fi and mobile data if it thinks another connection is stronger. This often causes random Wi-Fi drops.

To disable it:

  1. Open Settings → Wi-Fi → Wi-Fi Assistant.

  2. Turn off “Select best networks automatically.”

  3. Reconnect to your Wi-Fi manually.

This ensures your phone stays connected to your chosen network without switching.

🧰 Step 4: Reset Wi-Fi, Mobile, and Bluetooth Settings

If you’ve made multiple network changes or installed a recent update, your connection settings may have bugged out.

You can reset them easily:

  1. Open Settings → Connection & Sharing.

  2. Tap Reset Wi-Fi, mobile networks, and Bluetooth.

  3. Confirm the action and restart your device.

This won’t delete your personal files — only your saved Wi-Fi networks and paired Bluetooth devices.

🌐 Step 5: Check Router Frequency Band (2.4GHz vs 5GHz)

Some Redmi Note 13 units occasionally fail to connect to 5GHz Wi-Fi networks due to compatibility or distance issues.

Try this:

  • Log in to your router settings from a PC or phone browser (usually 192.168.1.1 or 192.168.0.1).

  • Check your Wi-Fi frequency band.

  • If it’s set to 5GHz, try switching to 2.4GHz — it has better range and compatibility.

✅ Tip: Many routers allow both 2.4GHz and 5GHz simultaneously. Rename them slightly differently (e.g., “HomeWiFi_2G” and “HomeWiFi_5G”) and connect to the stable one.

🔋 Step 6: Disable Battery Saver and Performance Modes

Battery optimization settings sometimes limit background Wi-Fi activity.

To disable:

  1. Go to Settings → Battery → Battery Saver.

  2. Turn off Battery Saver mode.

  3. Also check Settings → Apps → Manage Apps → [Wi-Fi or WLAN] → No restrictions under “Battery saver.”

This ensures your phone’s Wi-Fi stays active even when the screen is off.

🧱 Step 7: Check for MAC Filtering or Blocked Devices

If other devices can connect to Wi-Fi but your Redmi Note 13 cannot, your router might be blocking your device’s MAC address.

To fix this:

  1. Log in to your router’s admin panel.

  2. Look for MAC Address Filtering or Access Control.

  3. If enabled, turn it off or add your Redmi’s MAC address to the allowed list.

Find your device’s MAC address under:
Settings → About Phone → All Specs → Status → Wi-Fi MAC Address.

⚙️ Step 8: Update MIUI / HyperOS Software

Sometimes Wi-Fi bugs are fixed through system updates.

To check for updates:

  1. Go to Settings → About Phone → System Update.

  2. Tap Check for updates.

  3. If available, download and install the latest version.

After the update, restart your phone and reconnect to Wi-Fi.

🧼 Step 9: Clear Wi-Fi Cache and Data

If your Wi-Fi keeps disconnecting or won’t connect properly:

  1. Go to Settings → Apps → Manage Apps.

  2. Search for “Wi-Fi” or “WLAN.”

  3. Tap Storage → Clear Data and Clear Cache.

  4. Restart your device.

This removes old temporary files that might be interfering with your connection.

🧩 Step 10: Use Static IP Configuration (Advanced Users)

Sometimes the problem is related to DHCP (automatic IP assignment). You can fix it manually:

  1. Go to Settings → Wi-Fi.

  2. Tap the network you’re connected to → Modify network.

  3. Expand Advanced options → IP settings → Static.

  4. Enter these sample values (adjust if needed):

    • IP address: 192.168.1.120

    • Gateway: 192.168.1.1

    • DNS 1: 8.8.8.8

    • DNS 2: 8.8.4.4

This forces a stable manual connection.

🔁 Step 11: Factory Reset (Last Resort)

If none of the above steps fix the Wi-Fi issue, you might be dealing with a deep system-level glitch.

Performing a factory reset can often clear it up — but make sure to back up your data first.

  1. Go to Settings → About Phone → Factory Reset.

  2. Tap Erase all data.

  3. After reset, reconnect to Wi-Fi again.

⚠️ Warning: This will delete all files, apps, and settings. Only use this as a last step.

📶 Step 12: Test Wi-Fi Hardware (Optional Check)

If the problem persists even after resetting everything, there might be hardware damage — possibly the Wi-Fi antenna.

Try connecting to multiple Wi-Fi networks (home, café, hotspot).

  • If it works elsewhere, your router is likely the issue.

  • If it fails everywhere, visit a Xiaomi service center to test the hardware.

🧠 Bonus Tips for a Stable Wi-Fi Experience

  • Keep your phone close to the router; avoid thick walls and metal surfaces.

  • Regularly reboot your router (once a week).

  • Avoid overcrowding your Wi-Fi channel — switch channels via your router admin page.

  • Don’t use battery cleaner apps that force-stop background services.

  • Use Google DNS or Cloudflare DNS (1.1.1.1) for faster connectivity.

✅ Final Thoughts

Wi-Fi problems on the Redmi Note 13 are quite common — but in most cases, they’re caused by minor software glitches or misconfigured settings. By following the 12-step guide above, you can quickly identify whether the issue lies in your router, MIUI settings, or network configuration and fix it without any professional help.

If the Wi-Fi issue continues even after resetting and updating, the problem could be hardware-related, and it’s best to contact an authorized Xiaomi service center for diagnosis.

Once fixed, your Redmi Note 13 should reconnect smoothly — keeping your streaming, downloads, and browsing lightning-fast again.
