Try switching your router to a less crowded channel or using the 5 GHz band. Also, make sure there are no thick walls or strong sources of interference, such as microwave ovens, between the router and your devices.
⚠️ Please note: The interfaces of webOS, Android, and iOS operating systems are updated regularly. Menu locations and item names may differ from those described in the instructions. Always consult the official user manuals for your specific model.
In some cases, resetting the network settings helps. Unplug the router for 10-15 seconds, then plug it back in and wait for it to fully boot up. Afterwards, reboot your TV and smartphone. This simple procedure resolves most temporary software glitches in network modules.
If none of these methods work, check the date and time on both devices. Time missync can cause security protocol errors and prevent the connection. Set both devices to sync automatically via the network.
