This article explains how to connect a smart TV to a home network and the internet using Wi-Fi and troubleshoot issues making a connection.

The on-screen menu appearance and navigation for Wi-Fi setup may vary depending on the smart TV brand and model but include the same core steps. Some TV brands refer to Wi-Fi directly or use the terms Wireless, Wireless Network, Wireless or Wi-Fi Home Network, or Wi-Fi Network. The examples in this article use the term Wireless.

Connect to Wi-Fi During First-Time TV Setup

Here's how to connect your smart TV to the internet using your Wi-Fi network:

  1. Make sure your network and internet are working.

    To connect to Wi-Fi, you need a wireless router and your network name. For example, ATTxxx, TWCxxx, Coxaaa, or something you came up with.

  2. Turn on your smart TV. You'll see a Welcome or Setup screen.

    Don't turn off the TV or perform another function while the update is in progress.

  9. Once the update is complete, the TV directs you through the rest of the setup. These steps may include adding streaming apps, channel scanning for antenna-connected TVs, and picture and sound settings.

Change or Add Wi-Fi After the Fact

If you want to switch from a wired connection to Wi-Fi, installed a new wireless router, or changed your internet service provider (ISP), you can re-establish a Wi-Fi connection.

  1. From the TV's home screen, select the Setup or Settings icon.

What to Do if Your TV Won't Connect to Wi-Fi

If you can't connect your TV to Wi-Fi, or the connection is unstable, try one, or more, of the following steps.

  1. Move the wireless router and TV closer together, or get a Wi-Fi extender for the router and connect again using the above steps.

  2. If the Wi-Fi connection attempts fail, and the TV and router provide an Ethernet Port, connect an Ethernet Cable from the router to the TV.

    Depending on the TV brand and model, the Ethernet connection may be labeled Ethernet/LAN or LAN (Local Area Network). The Ethernet cable may be referred to as a network cable.

  3. In the TV's network settings menu, select Wired. You may be prompted to connect the Ethernet cable.

  6. If none of the above options work, contact your internet service provider (ISP) for assistance in entering the router's IP address and DNS server information manually.

  7. If your ISP didn't solve the problem, contact customer support for your TV for assistance.

Not All Smart TVs Have Wi-Fi

Older model smart TVs may not have a Wi-Fi option. If your smart TV doesn't have Wi-Fi but has an Ethernet or USB port, you may be able to access Wi-Fi with an Ethernet or USB Wi-Fi Adapter.

Consult the user guide or contact customer support to determine if you can use this option and which Wi-Fi adapters may be compatible.
