Router Requirements: Mi WiFi Amplifier 2 R02 Compatible with most models, but for stable operation, the router must maintain the standard 802.11n (or higher) at 2.4 GHz. If your router only works in the 5 GHz band, the repeater will not be able to connect.

• 📶 Check the current Wi-Fi signal: measure the signal level in the place where you plan to install the amplifier. 1-2 division 4-5) If there's no signal at all, the repeater won't be able to amplify it.
• 🔌 Prepare the socket: the amplifier must be connected to the 220V network without the use of extension cords or network filters - they can cause interference.
• 📱 Stock up with the device for setting up: you will need a smartphone, tablet or laptop with Wi-Fi support. WPS Possible, but not always stable.

A critical mistake many users make is to install the repeater in a place where the signal is too weak. If the Wi-Fi indicator on the amplifier flashes red or does not burn at all, move the device closer to the router.

2. Connect Xiaomi Mi WiFi Amplifier 2 R02 router: 3 ways

The amplifier can be configured in three main ways: through the web interface, using a button. WPS Or through the Mi WiFi mobile app (available for Android and iOS.

Method 1: Configure via web interface (recommended)

This is the most reliable method that works even if you don't have a smartphone at hand.

1. Connect the amplifier to the outlet next to the router (at a distance) 1-2 square).
2. Wait until the Wi-Fi indicator starts flashing blue (setting mode).
3. On a computer or smartphone, connect to the amplifier network - it will be called Xiaomi_XXXX (where XXXX — unique identifier).
4. Open your browser and go to 192.168.0.1 or miwifi.com.

For this:

1. Connect to the amplifier network (either via cable or Wi-Fi).
2. Go to the web interface at 192.168.0.1.
3. In the menu, select Wi-Fi settings → Main settings.
4. In the field Name of the net (SSID) Enter a new name (or copy the router name).
5. In the Password field, specify a new security key (minimum 8 characters).
6. Save the settings and restart the amplifier.

⚠️ Note: If you do the same thing SSID On a router and an amplifier, some devices (especially older smartphones) can stick to a single access point.
