4. Step-by-step setup of Smart Box as a repeater

Once the repeater mode is activated (or the firmware is updated), we proceed to the main setup. Your task is to specify Smart Box, which network it should connect to as a repeater.

1. In the web interface, find the section Wireless → Repeater Settings (or similar).

2. Click Scan — the device will display a list of available networks. Select your primary Wi-Fi network.

3. Enter the password for the main network (it must match the one indicated on the sticker of the main router).

4. In the field SSID for Repeater Specify the name of the new network (you can leave it the same as the main router, or add a suffix, for example _EXT).

5. Save the settings (Save/Apply) and wait for the reboot.

After successful setup Smart Box should start distributing Wi-Fi with a new name. Connect to this network and check the speed via SpeedtestIf the speed has dropped by more than 50%, try changing the Wi-Fi channel on your main router (optimally - 1, 6 or 11 for 2.4 GHz).

5. Optimizing repeater operation: channels, power, security

Even after successful setup, the repeater may still operate unstable. Here are the key parameters to adjust for maximum performance:

1. Selecting a Wi-Fi channel

The main router and repeater should operate on the same channel, but if you have a lot of neighbors with Wi-Fi in your home, choose the least crowded channel. To do this:

• 📊 Use the app Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS) for scanning the airwaves.
• 🔢 In the settings of the main router, set a fixed channel (for example, 6 for 2.4 GHz), not Auto.

2. Transmission power

In some firmware Smart Box you can increase the transmission power (parameter Tx Power). The optimal value is 100% (or 20 dBm). However, if the repeater is close to the main router (less than 5 meters), reduce the power to 50–70%to avoid interference.

3. Security

Make sure the repeater uses the same encryption type as the main router (WPA2-PSK or WPA3). If the main network is running on WPA3, and the repeater does not support this standard, you will have to temporarily switch the main router to WPA2.

6. Common mistakes and their solutions
