A simple restart solves a lot
Start with the basics: unplug the TV for 30 seconds, then plug it back in, and separately restart your router the same way. Restarting both devices together resolves a significant share of temporary connection issues.
Check the network frequency
Many routers broadcast two networks — 2.4 GHz and 5 GHz. Older Smart TV models sometimes only see the 2.4 GHz network, while the router shows the faster 5 GHz network to clients by default.
Check your router settings for a separate 2.4 GHz network (often named similarly to your main one, with "2.4" or "-2G" added), and connect the TV to that one specifically.
If the network is visible but the connection keeps dropping
This is often caused by distance from the router — thick walls (especially common in older Batumi buildings) weaken the signal. If the TV is far from the router, a Wi-Fi signal booster can help, or switching to a wired Ethernet connection if the TV has that port — the most reliable option for a stationary device.
It's also worth checking for firmware updates on the TV — manufacturers frequently release fixes specifically for Wi-Fi issues.
