Underlying causes of your Vizio smart TV not connecting to wifi

Disabled DHCP
This is the network protocol that allows your deviceto automatically allocate a dynamic IP address so that your device can communicate with other IP addresses. When this setting is disabled, your tv isn’t able to identify the IP address that it has been allocated, so it won’t connect to your wifi.
