@Kayleigh40 as a first step unplug or switch off the power to your TV until the power led goes out then reconnect it which should make it reboot. When going into the TVs settings make sure you choose the setting to get network details from the router the desscription varies but it is normally the default. Once connected to the wifi then thecT`v should get an IP address between 192.168.0.2 to 192.168.0.254 which means it can connectvtomthe internet.
