Reconnect Repeater After SSID or Password Change

Why the Repeater Stops Working After You Change Wi-Fi Details

A Xiaomi WiFi Repeater stores the router’s SSID (network name) and password from the moment it was paired. When you change either of these on the main router, the repeater may:

  • disconnect and show an error/offline status,

  • keep broadcasting an extended network but with no internet,

  • reconnect briefly, then drop again,

  • appear “online” in the app but devices fail to load anything.

This is normal behavior: the repeater is still trying to log in using the old credentials.

Before You Start: Identify What Changed

Use this quick checklist to choose the correct fix:

  • Only password changed → update credentials / reconfigure.

  • Only SSID changed → reselect the correct network (new name).

  • SSID + password changed → easiest is often reset + re-pair.

  • Router replaced or moved to a new environment → reset and reinitialize is typically required.

  • 2.4 GHz / 5 GHz settings changed (split SSIDs, band steering, channel width/security) → may need re-pair or router setting adjustments.

Step 1: Confirm the Router Is Working Normally

Before blaming the repeater, make sure the main network is stable.

  1. On Android, connect directly to the main router Wi-Fi (not the extender).

  2. Check:

    • internet works (open a few sites/apps),

    • password is correct (reconnect once to confirm),

    • the SSID is visible (especially if you disabled “broadcast SSID”).

If the router itself has no internet, fix that first. A repeater cannot solve an upstream outage.

Step 2: Power Cycle the Repeater (Fastest Low-Effort Fix)

Sometimes the repeater can reconnect automatically after a router change if the SSID stays the same and only minor settings were adjusted.

  1. Unplug the repeater.

  2. Wait 10 seconds.

  3. Plug it back in.

  4. Wait 1–3 minutes for it to stabilize.

Check the indicator status

Many Xiaomi models use indicators like:

  • Solid blue: connected and receiving a strong signal

  • Orange: weak signal (move closer to router)

  • Red: disconnected

If it stays disconnected (often red), continue to the next steps.

Step 3: Reconnect Using Xiaomi Home (Recommended Method)

If your repeater is already added to the Xiaomi Home (Mi Home) app, the cleanest path is to update the network settings there.

A. When only the Wi-Fi password changed (SSID stayed the same)

  1. Open Xiaomi Home on Android.

  2. Tap your WiFi Repeater device.

  3. Look for Wi-Fi settings or network settings.

  4. Update the password to match the router.

  5. Save and wait for the device to reconnect.

Tip: After saving, keep the phone near the router and repeater to reduce setup failures.

B. When the SSID changed (new Wi-Fi name)

  1. Open Xiaomi Home.

  2. Go to the repeater device page.

  3. Choose the correct Wi-Fi network from the list (the new SSID).

  4. Enter the new password and complete the reconfiguration.

If the app does not offer a smooth “change network” flow for your model, the most reliable solution is usually reset + re-pair (next section).

Step 4: Reset and Re-Pair (Most Reliable After SSID/Password Changes)

If you changed both SSID and password, replaced the router, or the repeater refuses to reconnect, do a full reset.

How to reset Xiaomi WiFi Repeater

  1. Keep the repeater plugged in.

  2. Find the Reset button (often a small pinhole).

  3. Press and hold for more than 5 seconds.

  4. Release when the indicator changes to a reset state (commonly steady yellow), then it returns to pairing-ready behavior.

This reset method and time duration is commonly referenced in Xiaomi support guidance for the Mi Wi-Fi Range Extender series.

Re-pair via Xiaomi Home (Android)

  1. Plug the repeater near the router for first setup.

  2. Open Xiaomi Home → Add device.

  3. Select your repeater model (or use search).

  4. Choose your router SSID and enter the new password.

  5. Wait until the app confirms successful setup (often indicated by solid blue).

Step 5: If Your Router Supports WPS / “MiNET,” Use the Shortcut (Optional)

Some setups allow pairing using:

  • WPS (common on many routers), or

  • MiNET (on certain Xiaomi routers)

Typical WPS pairing idea

  • Press the router’s WPS button,

  • then press the repeater’s pairing/WPS button (if your model includes it),

  • wait for the indicator to confirm connection.

If WPS succeeds, it’s quick—but app setup tends to be more consistent for managing settings later.

Step 6: Fix Common “Reconnect Failed” Causes

If you reset/repaired and it still won’t connect, these are the usual reasons:

1) The repeater is too far from the router during setup

  • Pair next to the router first, then relocate later.

  • If the signal indicator shows weak (often orange), move closer until it stabilizes.

2) Router Wi-Fi security is incompatible

Most repeaters work best with widely compatible settings such as:

  • WPA2-Personal (AES)

If you enabled a strict mode (for example, a newer security-only option or unusual enterprise settings), try switching to a more compatible WPA2/WPA2-WPA3 mixed mode (if available) and test again.

3) Hidden SSID (Wi-Fi name not broadcast)

Hidden networks can complicate repeaters because scanning and reconnecting becomes unreliable.

  • Temporarily enable SSID broadcast, connect the repeater, then decide if you want to hide it again.

4) Band steering / merged SSIDs causing confusion

If your router uses one SSID for both 2.4 GHz and 5 GHz, some repeaters (or phones) may behave inconsistently depending on signal.

  • If possible, temporarily set a clear 2.4 GHz SSID for pairing.

  • After pairing, you can decide whether to keep SSIDs merged or separate.

5) MAC filtering / access control on the router

If you enabled router controls that block unknown devices, the repeater may be denied.

  • Check the router’s blocked device list and allow the repeater.

Step 7: After Reconnecting, Prevent the Next Disconnect

These small habits reduce future issues when you edit Wi-Fi settings again.

A. Change one setting at a time

If you must change the router’s Wi-Fi:

  1. change password first (test),

  2. then change SSID (test),

  3. then change security/band settings (test).

This makes it easier to identify what broke compatibility.

B. Keep a stable 2.4 GHz option for the repeater

Even if you love 5 GHz for speed, 2.4 GHz is often more dependable through walls for the repeater’s “upstream” connection.

C. Place the repeater for a strong upstream signal

A repeater that’s barely connected will drop more often after any router adjustments.

  • Aim for the repeater’s indicator to show a strong state (commonly solid blue).

Quick Troubleshooting Flow (Fast Decisions)

Use this if you want the shortest path:

  1. Router works on phone directly?

    • No → fix router/ISP first

    • Yes → continue

  2. Power cycle repeater (unplug 10 seconds)

  3. Still offline?

    • Open Xiaomi Home and update network settings

  4. Still failing or SSID changed?

    • Reset (hold > 5 seconds) → re-pair near router

  5. Still failing?

    • Enable SSID broadcast, use WPA2-Personal, check MAC filtering, retry pairing
