  • 🌐 Different subnets: if the router distributes several SSID (For example, 2.4 GHz and 5 GHz devices may be on different networks.
  • 🔒 Router firewall: some models (e.g. TP-Link Archer) C6) Blocking multicast traffic required for Miracast.
  • 📶 Weak signal: stable mirroring requires a speed of at least 15 Mbit / s. At a lower speed, the connection will break.

How to check:

  1. Open on Xiaomi Settings → Wi-Fi and remember the name of the network and IP-address (e.g. 192.168.1.100).
  2. On TV. LG Go to Settings. → Network → Network status and compare IP (must be in the same range, e.g. 192.168.1.101).
  3. If IP differing, for example, 192.168.0.x vs 192.168.1.x), Reconnect both devices to the same 2.4 GHz network.

If the problem is in the router, try:

Enter 192.168.1.1 (or 192.168.0.1) in the browser address bar


Go to the section "Wireless mode" → "Wi-Fi settings"




Turn off the option of "Customer Isolation" (AP Isolation)
