These compact devices eliminate dead zones in the apartment or home where the main router signal weakens, but many users face difficulties when first connecting or setting up additional settings.

In this article you will find step-by-step instructions for setting up the Xiaomi amplifier - from the basic connection through the WPS We will also address common errors (such as when a device is not connected to the network or flashes orange), reset settings and optimize the location of the repeater for maximum efficiency. Special attention is paid to the features of firmware 2023-2026, where the authorization algorithm in the Mi Home mobile application has changed.

If you have just purchased an amplifier or are trying to reconfigure your old one, this guide will help you avoid common problems and achieve a stable signal in all rooms.

1. Preparation for setting up: what to check before connecting

Before you start setting up, make sure that all the conditions for a successful connection are met, which will save time and eliminate the need to reset the device due to banal errors.

Requirements for the main router:

• 📶 The router must maintain the standards. 802.11n (2.4 GHz) or 802.11ac (5GHz Xiaomi amplifiers are compatible with most current models, but may not work with legacy devices (e.g. routers before 2012 release).
• 🔒 The router must have the filter turned off. MAC-Addresses (if enabled) This feature blocks new devices from connecting.
• 🔄 Regime. WDS Repeater on the main router should be turned off – the Xiaomi amplifier will work in this mode.
• 📡 If the router is dual-band, decide in advance which range you will expand: 2.4 GHz (long range, but lower speed) or 5 GHz (high speed, but less coverage).

Amplifier requirements:

• 🔋 The device must be connected to the outlet in the area of the main router (no further than 10-15 meters in the absence of obstacles).
• 🔄 The Reset button (on the back) should not be pressed – this will reset all settings.
• 📱 To set up via the Mi Home app, check that your smartphone is connected to the same Wi-Fi network you plan to expand.

⚠️ Note: If your router uses non-standard security settings (e.g, WPA3-Enterprise or 802.1X), Xiaomi's amp might not be connected, so you'll have to switch to a temporary powertrain. WPA2-PSK.

2.How to connect the Xiaomi amplifier: WPS vs manual setting

There are two main methods of setting up the Xiaomi amplifier: through the button. WPS (The fastest way to do this is through a web interface or a Mi Home app (more flexible.

Method 1: Connection through WPS (Recommended for most users)

Technology WPS (Wi-Fi Protected Setup allows you to connect the amplifier to the router without entering a password. WPS (Usually there is a button with such an inscription or icon. 🔄).

Step-by-step:

1. Connect the Xiaomi amplifier to the outlet. Wait for the indicator to flash blue (plug-in waiting mode).
2. Press the WPS button on the router (usually you need to hold 2-3 seconds).
3. Press the button for 2 minutes. WPS on the Xiaomi amplifier (located on the side or back panel).
4. Wait until the indicator on the amplifier lights up blue (successful connection) or orange (error).

If the indicator flashes orange, repeat the procedure or go to manual settings, sometimes it helps to reboot the router before reconnecting.

Method 2: Manual connection via web interface or Mi Home

If WPS does not work or you want to configure additional settings (for example, change the name of the extended network), use the manual method.

Option A: Through the web interface (for PC)

1. Connect the amplifier to the outlet and wait until it goes into setting mode (blinking blue indicator).
2. On the computer, connect to the network. Xiaomi_Ext (or similar, see the sticker on the device. 1234567890.
3. Open your browser and go to http://192.168.0.1 or http://miwifi.com.
4. Enter the administrator password (often empty or admin by default).
5. Select the network to expand from the list, enter a password from it and save the settings.

Option B: Through the Mi Home app (for smartphones)

1. Install the Mi Home app (available for Android and iOS).
2. Sign up or sign in to your Xiaomi account (required! no setup is possible without an account).
3. Click Add Device → Wi-Fi amplifier.
4. Follow the instructions on the screen: select the network, enter the password and wait for the configuration to be completed.

⚠️ Note: In 2026, the Mi Home app may request confirmation SMS when you add a new device. SMS Check if the Xiaomi number is locked in your phone.

Make sure the router is turned on and gives out Wi-Fi

Check that the smartphone is connected to the router network (not to mobile data)

Shut down. VPN on your phone (can block access to miwifi.com)

Reboot the amplifier if the indicator does not flash blue-->

3. Optimal placement of the amplifier: how to avoid loss of speed

The wrong location of the amplifier can not only not improve the signal, but also worsen the speed of the Internet due to a double “jump” of data (router). → booster → Follow these recommendations:

Where to put the amplifier:

• 📍 Signal overlap zone: The amplifier should be located where the main router signal is still stable (at least 2-3 "rods" on the smartphone), but is already beginning to weaken.
• ⚡ Proximity to the socket: Avoid extension cords - they can cause interference. Use the socket without other powerful consumers (for example, a refrigerator).
• 🚫 Obstacles: Concrete walls, metal cabinets and mirrors weaken the signal. Put the amplifier in an open space (for example, on a shelf, not in a cabinet).
• 🌐 Height: It is better to place the device at a height of 1-1.5 meters from the floor - this reduces interference from furniture.

What to avoid:

• 🔌 Multiple amplifier chain: Connecting one repeater to another (router) → booster 1 → the amplifier 2) results in a loss of up to 50% of the speed on each "jump».
• 📡 5 GHz long distance: 5 GHz range doesn't go well through walls. If the distance between the router and the amplifier is more than 10 meters, use 2.4 GHz.
• 🔄 Network congestion: If more than 10 devices are connected to the amplifier, the speed for each will decrease.

💡

If you have a dual-band router, name the network. 2.4 GHz 5 GHz by different names (for example, MyWiFi_2G and MyWiFi_5G). This will allow you to manually choose which range to connect through the amplifier.

4. setting additional parameters (for experienced users)

The basic setup of the amplifier is usually enough, but in some cases, a fine configuration is required.

• 🔒 Change the name of the extended network (by default it duplicates the main network with the addition of the network _EXT).
• 📶 Disable the 5GHz extension if you don't need it.
• 🔄 Set up an amplifier schedule (for example, turn off at night).
• 🔐 Enable the guest network through the repeater.

And you'll need access to the web interface of the amplifier, and here's how to get there:

1. Connect to the amplifier network (its name will be different from the main one, for example). Xiaomi_Ext_1234).
2. Open your browser and go to http://192.168.0.1 or http://miwifi.com.
3. Enter the login and password (by default — admin/admin or see the sticker on the device).

Popular settings in the web interface:

• Change the network name: Go to Wi-Fi settings → Main settings. Network name in the field (SSID) Enter a new name. We recommend adding a suffix (e.g., Repeater) to distinguish it from the main network.
• 5GHz Disconnection: In the Wi-Fi Settings section → 5 GHz range uncheck with Enable.
• Schedule settings: In Additional settings → Schedule can be specified time of automatic disconnection / activation of the amplifier.

⚠️ Note: If you change the name of the network (SSID) or a password in the amplifier's web interface, all connected devices will be disabled and they will have to log in again.

Typical problems and their solutions

Even when set up correctly, Xiaomi’s amplifier can run unstablely, and we’ll look at some of the most common errors and how to fix them.

If the amplifier flashes orange and does not connect:

1. Make sure the router is not using a hidden network (disable Hide option). SSID).
2. Check what's on the router. DHCP (Otherwise, the amp will not receive IP-address).
3. If you use PPPoE, make sure that the login/password is entered on the router, not on the amplifier.
4. Try changing your Wi-Fi channel on your router (for example, from an automatic to a fixed 6 or 11).

If the speed through the amplifier drops sharply:

• 📉 Check the speed directly from the router (without the amplifier).If it is also low, the problem is with the provider.
• 🔄 Switch the amplifier to a different range (from 5 GHz to 2.4 GHz or vice versa).
• 📡 Reduce the number of connected devices or disable background downloads (torrents, updates).

💡

If the Xiaomi amplifier is permanently shutting down, check the firmware version via the web interface. in older versions (before 2023) there was an overheating error that is fixed in new updates.

6. Resetting the amplifier settings to factory

If the amp is not working properly or you have forgotten the password from its web interface, you may need to reset completely, which will return all parameters to the factory, including the network name and password.

How to reset your settings:

1. Find a small hole on the back of the amplifier that says Reset.
2. Take a paperclip or toothpick and press the button inside the hole.
3. Hold it for 10-15 seconds until the indicator blinks quickly.
4. Release the button and wait for the reboot (the indicator will light up in blue).

After resetting, the amplifier will be available by default:

• 📶 Name of the network: Xiaomi_Ext or MiWiFi_Repeater (see sticker).
• 🔐 Password: 1234567890 or blank.
• 🌐 IP-Web interface address: 192.168.0.1.
• 👤 Login/admin password: admin/admin.

⚠️ Warning: After resetting, the amplifier will not save the previous connection settings to the router. You will have to re-configure the procedure (via the router). WPS web-based).

7. firmware update: when and how to do it
