At this point, the physical connection is established, and you can move on to the logical configuration.

⚠️ Caution: Do not connect the ISP cable to the yellow LAN ports or the computer cable to the blue WAN port. This error will prevent the router from accessing the internet, although the local network will still function.

Login to the administrator web interface

To manage router settings Xiaomi A built-in web interface is used. It can be accessed through any modern browser. By default, the device has a standard IP address, which is written on a sticker on the bottom of the case, but in most cases, a domain name is sufficient.

  • 🚀 For the 5 GHz band, use the name "Home_WiFi_5G" and select the channel with the least load (automatic selection is often optimal).
  • 🔒 The password must contain at least 8 characters, including letters and numbers, to protect the network from neighbors.
