It is also recommended to disable automatic app updates in stores. Galaxy Store And Google Play while watching.
Temperature is an important factor. When actively distributing Wi-Fi, the phone's processor heats up, which can lead to throttling (reduced performance) and a drop in network speed. Remove your smartphone's case and place it on a hard surface to improve heat dissipation.
| Parameter | Recommended value | Influence on TV |
|---|---|---|
| Frequency range | 5 GHz | High speed, less interference |
| Security protocol | WPA2 PSK | Maximum compatibility |
| Shutdown timeout | Never / Always On | Prevents connection breakdown |
| Maximum devices | 1-2 | Allocates all resources to TV |
Solutions to common problems and errors
Despite the simplicity of setup, users may encounter difficulties. One common issue is that the TV sees the network but fails to connect or displays an "Authentication Error." In this case, try changing the security type in the access point settings on your phone. WPA3 on WPA2, since the old modules in TVs LG may not support new encryption standards.
Another common situation is that the connection is there, but the internet doesn't work. This is often due to DNS settings. On the TV LG You can specify static DNS addresses in the network settings, for example, from Google (8.8.8.8) or Cloudflare (1.1.1.1) This helps to bypass some operator blocking.
- 🔄 Reset your TV's network settings using the menu
Network → Advanced Settings → Edit. - 📶 Restart the Wi-Fi module on your phone by turning the access point off and on again.
