Fix Xiaomi WiFi Repeater Not Connecting to Router

What “Not Connecting” Usually Looks Like

When a Xiaomi WiFi Repeater can’t connect to your router, you may notice one or more of these symptoms:

• The repeater doesn’t appear in Xiaomi Home (Mi Home) during setup

• Setup gets stuck at “Connecting…” or “Failed”

• The repeater broadcasts a Wi-Fi name, but devices show “No internet”

• The LED shows an error state (varies by model), and the app shows offline

• It connects briefly, then drops again

The good news: most cases are caused by placement, router settings, or a repeater that isn’t truly in pairing mode—all fixable.

Know Your LED Signals (So You Don’t Guess)

Different Xiaomi extender models use slightly different LEDs, but these patterns are commonly documented:

Mi Wi-Fi Range Extender Pro (R03) style indicators

• Solid blue: connected / working normally

• Flashing blue: updating

• Solid yellow: starting

• Flashing yellow: ready for initialization / pairing

• Flashing red: hardware error

Mi WiFi Range Extender AC1200 style indicators

• Solid blue: strong signal / connected

• Solid orange: weak signal (move closer to router)

• Solid red: disconnected (out of range or not connected)

• Flashing red: ready for initialization (pairing-ready on some guides)

If you’re unsure which you have, treat a “flashing / ready” state as pairing mode and solid blue as “connected.”

Step 1: Do the Two-Minute Reality Check (Router + Phone)

Before troubleshooting the repeater, confirm the router is stable:

1. On Android, connect directly to your router Wi-Fi.

2. Confirm:

   • Internet works (open a few sites/apps)

   • SSID is visible (not hidden during setup)

   • Password is correct (reconnect once to confirm)

If the router itself is unstable, fix the router/ISP first—repeaters can’t improve an unstable upstream connection.

Step 2: Place the Repeater Correctly (Most Common Cause)

The rule that prevents most failures

For setup, plug the repeater near the router (same room, a few meters away).

Why this matters:

• During pairing, the repeater must receive a strong signal to register, authenticate, and save credentials.

Avoid these “setup failure” placements

• Inside cabinets

• Behind TVs/consoles

• Near microwaves

• Near metal shelves, mirrors, thick concrete pillars, or water tanks

Once connected (often solid blue), you can move it later—just don’t start setup in a weak-signal location.

Step 3: Put the Repeater into True Pairing Mode (Reset Properly)

If the repeater was used before, or the app can’t detect it, reset it.

Factory reset steps (typical Xiaomi guidance)

1. Keep the repeater plugged in.

2. Press and hold Reset for at least 5 seconds.

3. Release and wait until the indicator shows the pairing-ready state (often flashing yellow, or flashing red on some AC1200 guides).

After reset, keep it near the router and try setup again.

Step 4: Set Up Again in Xiaomi Home (Android)

Recommended clean setup flow

1. Open Xiaomi Home / Mi Home on Android.

2. Tap Add device (the “+”).

3. Search/select your extender model.

4. Confirm the repeater is in pairing mode.

5. Choose your router Wi-Fi and enter the password.

6. Wait until the app completes the process and the LED indicates normal operation.

If the app cannot find the device

Try this quick checklist:

• Turn Bluetooth on (some app flows use it)

• Toggle Wi-Fi off/on on the phone

• Temporarily disable VPN

• Temporarily disable mobile data (some phones behave better during setup)

• Keep the phone very close to the repeater

Step 5: Fix Router Settings That Commonly Block Connection

If the repeater keeps failing at “connecting to network,” the router may be rejecting it.

A. Disable Access Control / MAC Filtering (Blacklist/Whitelist)

Many routers have “Wireless access control,” “MAC filtering,” “Whitelist,” or “Blacklist.”

• Turn it off temporarily

• Reboot the router

• Pair again

B. Use a compatible security mode

For widest compatibility during setup, use:

• WPA2-Personal (AES)
  If your router is set to a very strict mode or unusual enterprise authentication, the extender may fail to join.

C. Avoid hidden SSID during setup

Hidden SSID can complicate discovery and authentication.

• Enable SSID broadcast temporarily

• Pair successfully

• Then decide if you want to hide it again (not recommended for repeaters)

D. Separate 2.4 GHz and 5 GHz (if needed)

Many extenders pair most reliably on 2.4 GHz.
If your router uses one combined name for both bands:

• Temporarily split SSIDs (2.4G and 5G)

• Pair the repeater to the 2.4G SSID

• Later you can keep split or recombine depending on stability

E. Adjust channel and channel width (2.4 GHz stability)

Crowded channels can cause pairing timeouts.

• Try changing the router’s 2.4 GHz channel (often 1/6/11 works best in many environments)

• Set 20 MHz width for stability in dense areas

• Reboot router → reboot repeater

Step 6: Use the “Mobile Hotspot Test” to Isolate the Problem

This is a powerful diagnostic recommended in Xiaomi troubleshooting guidance for extenders:

1. Turn on a mobile hotspot (Android phone hotspot).

2. Attempt to connect the repeater to the hotspot during setup.

How to interpret the result

• It connects to hotspot successfully:
  The repeater is likely fine; the issue is your router settings (security, access control, SSID, channels).

• It fails even on hotspot:
  The repeater may not be in proper pairing mode, may need another reset, or could be faulty.

Step 7: If It Connects but Drops Immediately

When the repeater connects then disconnects repeatedly, it’s often a signal quality or interference issue.

Fixes that work most often

• Move the repeater closer to the router (even one wall closer helps)

• Keep it away from electronics and metal surfaces

• Improve 2.4 GHz stability:

  • use less crowded channels

  • use 20 MHz width

• Reboot order:

  1. reboot router (wait until stable)

  2. reboot repeater

Watch for “weak signal” indicator (AC1200 often shows orange)

If you see a weak-signal color, relocation is not optional—your upstream link is too weak to stay connected.

Step 8: When to Reset and Reinitialize Again

Do a fresh reset and setup if:

• you changed SSID or password recently

• you moved the repeater to a new router/home

• the app shows the device but it never comes online

• the LED stays in an abnormal state after multiple attempts

Reset (hold ≥ 5 seconds) and repeat setup near the router.

Fast Fix Flow (If You Want the Shortest Path)

1. Confirm router Wi-Fi works on your phone

2. Plug repeater near router

3. Reset (hold ≥ 5 seconds) until pairing-ready LED

4. Add device in Xiaomi Home (Android)

5. If failed:

   • disable MAC filtering/access control

   • use WPA2-Personal

   • enable SSID broadcast

   • pair to 2.4 GHz

6. Run hotspot test to isolate router vs device issue
