Hello Mi Fans!
Mi India's new product in personal Wi-Fi Routers range -The "Mi Router 3C" is not only a sleek & beautiful device but it comes with some nifty features as well. One of the very useful features is the ability to use it in Repeater mode - Yes, another reason to buy MI Router 3C even if you already have a Wi-Fi router at home. So, Lets see how to set-up Mi Router 3C as a Repeater (or Range Extender)

What is a Repeater?
  • We are going to use Mi Router 3C as Wi-Fi Repeater or Range Extender to extend your Wi-Fi network. This is useful if you need a wide area coverage, (i.e. your home has multiple floor).
  • Mi Router 3C can be used both wired & wireless network extender (I am discussing only wireless, if you want to do the wired one then it is mostly the same)

What you need?
  • A working Wi-Fi Network i.e. an additional router with an active Wi-Fi connection. After all we are going to use this method to extend an existing Wi-Fi network using Mi Wi-Fi Router 3C.
  • Mi Router 3C with power cable.
  • A Pin to reset the router  a Sim tray ejector pin  (mine is custom made from a paper clip.. )
  • Optional: LAN cable (only if you want to extend the Wired network)
  • Mi Wi-Fi Router firmware version in use: ver 2.8.25 (Stable). I am using this rom but for other roms and other Mi routers (which are not lunched in India) setup will be similar.

Reset Router: (For a New Mi Router 3C, it is not required)

  • Connect the router to Power  wait for LED to become 'Blue'
  • Take the pin & hold down the reset button at the back.
  • Wait for LED colour to change. LED colour will change in - Blue  Orange  Blink(orange)
  • Remove it from Power & re-connect to Power. Wait for LED to become Blue.
  • Check the Wi-Fi networks in Mobile (or Laptop). Verify that you have the default SSIDs (networks).
  • If you see SSIDs like Xiaomi_XXXX_XXXX - then Reset completed successfully.
  • lf you still see the old SSID then try to reset again

    ~Steps from Mobile~

Step 1. Download Mi Wifi App from Google Playstore

Step 3. Open the App and Accept the pop-ups for various permissions.
Note: Ensure that your mobile data is off after connecting to Wifi network Xiaomi_XXXX_XXXX
Step 4. Click on "Set up a new router"  You will see "Checking connection..."
Step 5. Next Step will give you the option to choose the Wi-Fi mode  Choose "Wireless repeater mode"
Step 6. Tap on "Wi-Fi network"  Choose your home Wi-Fi network
Step 7. Enter your Wi-Fi Password  Click on "Finish"
Step 8. You will see following message "Applying Settings"

Note: This is the last step - Your Mi Router 3C is ready to be used as Repeater. Connect back to your home Wi-Fi network - you are good to go.

Steps from your Laptop's browser:

Step 1. Connect to Mi Router 3C Wi-Fi network -Xiaomi_XXXX_XXXX (or Connect via a LAN cable)
Step 2. Open a browser (I am using Internet Explorer) - (Default system browser lunches automatically once LAN cable is connected in Windows 10 -An observation)
Step 3. Go to or  Click on "Agree"

Step 4. Choose "Amplifier mode (extend existing Wi-Fi)"
Step 5. Choose an existing wireless network
(It detects your saved Wi-Fi network automatically - An observation)
Step 6. Enter your password  Click "Next"
Step 7. You can set an separate Network and secondary password for the new network from below - Just click "Skip" if you don't want to use an new SSID/wi-fi network name.
Step 8. Next page lets you set up your Wi-Fi Location and Admin password (this will be required for next time when you login to router)  After setting your Password click "Set up successfully"
Step 9. Last Page  Click on "Connect to Network" - This will re-direct to  Enjoy Surfing

Nicely explained. Thanks for sharing this thread.
@Er. Deep I have just 1 question regarding the  ...

Mi Router uses 192.168.31.x private network (by default) - where 1st IP of the network is reserved for Router administration (i.e. whereas most of the other Routers (Netgear/D-link/TP-link etc.) use 192.168.0.x private network (by default) & for administration (Router Web login page).

When you connect Mi Router to a non Mi Router in Repeater mode, it just re-broadcasts the 192.168.0.x network & hence you will not be able to access the default administration page via - So, in this scenario only way to manage the Mi Router 3C is via Mi Wi-Fi app.

In short, there is no issues on using Mi Router 3C in repeater mode with any other Router. (I am using it with a D-link router came along with my Airtel V-fiber connection)
