A Xiaomi Wifi Repeater keeps the Wi-Fi details used during setup. If the router name, password, security settings, or network environment changes, the repeater may need to reconnect or be configured again.

Check the Main Wi-Fi First

Confirm that the router itself is working before changing repeater settings.
[checklist] * Connect the phone directly to the main router Wi-Fi * Confirm internet access works normally * Reconnect once using the current router password * Confirm the correct SSID is visible * Check that router access control is not blocking the repeater [/checklist]If devices connected directly to the router also have no internet access, restore the main network first. The repeater cannot restore an upstream connection.
Restart the Repeater

A simple restart is worth trying first, especially when the SSID has stayed the same.
[step] 1. Unplug the repeater 2. Wait about 10 seconds 3. Plug it back in 4. Allow about 1–3 minutes for the connection to settle 5. Check the repeater status in the app or on its indicator [/step] [note] Indicator colors and behavior vary between Xiaomi repeater models. Use the status shown for your specific model rather than assuming every Xiaomi repeater uses the same color meanings. [/note]Reconnect Through Xiaomi Home
If the repeater is already available in Xiaomi Home or Mi Home, check whether your model provides network settings that allow the saved Wi-Fi details to be changed.
If Only the Password Changed
[step] 1. Open Xiaomi Home or Mi Home 2. Open the repeater device page 3. Check for Wi-Fi or network settings 4. Enter the router's current password if the option is available 5. Save the change and allow the repeater time to reconnect [/step]If the SSID Changed
[step] 1. Open the repeater device page 2. Select the router's new Wi-Fi name when network selection is available 3. Enter the current Wi-Fi password 4. Complete the configuration 5. Confirm that the repeater reconnects to the main router [/step] [tip] Keep the phone, repeater, and router reasonably close together while configuring the connection. [/tip]If your model or app version does not provide a direct network-change option, re-pairing the repeater is the more suitable path.
Reset and Re-Pair

Reset and re-pair when both the SSID and password changed, the router was replaced, the repeater was moved to a different network environment, or normal reconfiguration is unavailable.
[warning] Resetting clears the repeater's current network configuration, so it will need to be set up again. [/warning] [step] 1. Keep the repeater powered 2. Locate the Reset button or reset pinhole 3. Press and hold Reset for more than 5 seconds 4. Release it when the device enters its reset or initialization state 5. Place the repeater near the main router 6. Open Xiaomi Home or Mi Home and add the repeater again 7. Select the current router SSID and enter its password 8. Wait for setup to complete before moving the repeater to its normal location [/step] [note] Xiaomi documents a reset of more than 5 seconds for several range-extender models. The exact indicator behavior during initialization can vary by model. [/note]Optional Router Pairing
Some Xiaomi repeaters and routers support a shortcut such as WPS or MiNET. Availability depends on the repeater and router model.
- For WPS-capable equipment, use the router and repeater WPS controls according to the available buttons on those devices.
- Some Xiaomi routers support MiNET pairing with compatible Xiaomi range extenders.
- If these controls are not present, use the app-based setup flow instead.
Connection Checks
[troubleshoot] Problem: The repeater cannot complete setup Cause: The repeater, phone, and router may be too far apart during configuration Fix: Move the repeater near the router for setup, then relocate it after the connection is established Problem: The repeater is offline after the router change Cause: It may still have the previous SSID, password, or network configuration Fix: Restart it first, then update the network details or re-pair it if needed Problem: The router does not allow the repeater to join Cause: Router access control, a blacklist, whitelist, or MAC filtering may be restricting the device Fix: Check the router access-control settings and allow the repeater Problem: The repeater cannot see the intended network Cause: The SSID may be hidden or the selected Wi-Fi band may not be supported by that repeater model Fix: Temporarily make the SSID visible and confirm that the router is using a band supported by the repeater Problem: Connection behavior changed after router security settings were updated Cause: The selected wireless security mode may not be supported by the repeater Fix: Check the security modes supported by the specific repeater model and use a compatible router setting [/troubleshoot]Band Support Varies by Model
Do not assume all Xiaomi repeaters handle 2.4 GHz and 5 GHz in the same way. For example, some older Xiaomi repeater models operate on 2.4 GHz, while dual-band models can also use 5 GHz.
If the router combines both bands under one SSID and setup is inconsistent, temporarily using a clearly identifiable supported band can make network selection easier. After pairing, restore the router configuration you prefer if the repeater remains compatible with it.
SSID Visibility
A hidden Wi-Fi name can make discovery during setup less straightforward. Temporarily enabling SSID broadcast can help the repeater find the network, after which you can decide whether to change the router setting again.
Placement After Reconnection
Once pairing is complete, move the repeater to a location that still receives a usable signal from the main router. Avoid placing it where walls or other obstructions leave the upstream connection very weak.
[tip] If the app reports poor signal, reduce the distance between the repeater and main router before testing again. [/tip]
