Typical errors and their solutions

Even with the right setup, the Mi Wi-Fi Range Extender Pro may not work properly, and we'll look at some of the most common problems and how to fix them.

Problem 1: The repeater is not connected to the main network

Possible causes and solutions:

• 🔍 Incorrect password: Check the symbol register (password is sensitive to it!).
• 📶 Weak signal: Move the repeater closer to the router (3-5 meters).
• 🔄 Incompatible settings: Turn off the router 802.11r, WPA3 (use WPA2-PSK).

Problem 2: The indicator flashes orange

The orange color means that the repeater can't connect to the network.

• 🔌 Does the device power (try another socket).
• 📡 Whether Wi-Fi standards match (for example, if the router only runs at 5GHz and the repeater tries to connect to 2.4GHz).
• 🔒 Does the antivirus or firewall block the connection (switch them off temporarily).

Problem 3: Low Internet speeds via repeater

The speed will always be lower than when connecting directly to the router, but if the difference is critical:

• 📶 Switch the repeater to the 5 GHz band (if the router supports it).
• 🔄 Change the Wi-Fi channel in your router settings (use a 40-48 channel for 5 GHz).
