If you still have a remote
Connect the TV to the new network in its settings, then open Kliky on the same network.
If you have no remote
Kliky cannot reach a TV that is not on any network. Use a USB keyboard or mouse, an Ethernet cable or the hotspot method: connect a TV to Wi‑Fi without a remote.
Before you switch routers
While the old Wi‑Fi still works, use Kliky to open the TV’s network settings and join the new network. It saves the trouble above.
