Does anyone know off an online place to help set up my smart TV and what I would need to help the TV or wifi to boost the wifi signal so the TV can pick it up please help

Please clarify your question, further details would be useful.

Did you talk to the store where you purchased it? Did you check the support link for the manufacturer you purchased from? How far is the TV from your router? What type of router?

Have you tried doing a search on youtube for any videos they might have for your specific unit. Many people put up demos on how to set up and get going while also posting the pitfalls you could run into.
