The basic connection process

Roku TVs connect to the internet through either WiFi or an ethernet cable plugged into the back of the set. Most people use WiFi. When you turn on a new Roku TV for the first time, it walks you through a setup menu that asks for your WiFi network name and password — the same ones you use for your phone or laptop. Once you enter those details, the TV connects and you can start using it.

The whole process takes about five minutes. You do not need a separate Roku device or box; the Roku software is built into the TV itself. If you already own a Roku streaming device (like a Roku Stick or Roku Box), you can connect that to any TV using an HDMI cable, but a Roku TV does the same thing without the extra hardware.

Key Takeaways

  • Roku TVs connect to WiFi during the initial setup menu, which appears the first time you power on the TV.
  • You will need your WiFi network name and password to complete the connection.
  • An ethernet cable plugged into the back of the TV is an alternative if your WiFi signal is weak or unreliable.
  • Once connected, you can add streaming apps and sign into services like Netflix, Disney+, or Hulu directly on the TV.
  • A Roku account (free to create) lets you manage your apps and settings across devices, though it is not required to watch content.

WiFi connection step by step

When the setup menu appears on your screen, use the remote to navigate to the WiFi option. The TV will show you a list of available networks — look for your own network name (called the SSID). Select it, then enter your WiFi password using the on-screen keyboard. The remote has a directional pad and buttons that let you move between letters and numbers.

If your network does not appear in the list, make sure your router is turned on and within range of the TV. You can also scroll down in the network list to see if it appears further down. Once you select your network and enter the password correctly, the TV will connect within a few seconds. You will see a confirmation message on the screen.

If the connection fails, double-check that you typed the password correctly — passwords are case-sensitive, meaning capital letters matter. If you are unsure of your password, you can check it on your router (usually printed on a sticker on the device itself) or log into your router's settings from a computer or phone.

Using an ethernet cable instead

If your WiFi is slow, drops frequently, or does not reach the room where your TV is located, you can plug an ethernet cable directly into the port on the back of the Roku TV. This gives you a faster, more stable connection. During setup, when the TV asks how you want to connect, select the ethernet option instead of WiFi.

Ethernet cables are inexpensive — you can buy one at any electronics store or online for a few dollars. The cable runs from your router (or a wall outlet if your home has ethernet wiring) to the TV. Once plugged in, the connection is automatic; you do not need to enter a password.

Creating and signing into a Roku account

After your TV connects to the internet, Roku will ask if you want to create a free account or sign into an existing one. This step is optional — you can skip it and still watch content. However, a Roku account makes it easier to manage your apps, save your preferences, and move between devices if you own multiple Roku products.

To create an account, you provide an email address and a password. Roku uses this account to store which apps you have installed and your login information for services like Netflix or Hulu. If you already have a Roku account from a previous device, sign in with that email and password instead of creating a new one.

Your Roku account is separate from your streaming service accounts. You will still need to sign into Netflix, Disney+, Hulu, and other apps individually on the TV, even if you have a Roku account.

Adding apps and signing into streaming services

Once your TV is connected and set up, you can read apps from the Roku Channel Store. Use the remote to navigate to the home screen, then select "Search Channels" or "Add Channels." You will see a list of available apps — Netflix, Disney+, Hulu, YouTube, Prime Video, and many others. Select the ones you want and add them to your TV.

After you add an app, open it and sign in with your account for that service. For example, if you add Netflix, you will need to enter your Netflix email and password. The TV remembers these logins, so you only have to enter them once. After that, the app opens directly to your account.

Some apps are free to read but require a paid subscription to use (like Netflix). Others, like YouTube or Pluto TV, are free to use without a subscription. The app listing tells you which category each one falls into.

Troubleshooting a connection that will not work

If your TV will not connect to WiFi, start by restarting both the TV and your router. Turn off the TV, wait 30 seconds, and turn it back on. At the same time, unplug your router, wait 30 seconds, and plug it back in. This clears temporary problems that prevent connection.

If the TV still will not connect, check that you are entering the correct WiFi password. Passwords are case-sensitive and spaces count. If you are not sure, log into your router from a computer or phone to see or reset the password. You can also move the TV closer to the router temporarily to rule out a weak signal.

If your router requires a specific setup (like a guest network or a 5GHz band instead of 2.4GHz), check your router's manual or contact your internet provider. Some older Roku TVs only connect to 2.4GHz networks, not 5GHz, so if you have both available, try the 2.4GHz option first.

If none of these steps work, restart the TV's setup process. Go to Settings > System > System Restart, or unplug the TV for two minutes and plug it back in. When it restarts, you can run through the WiFi setup again from the beginning.

Connecting a separate Roku device to your TV

If you own a Roku Stick, Roku Box, or another Roku streaming device, you connect it to any TV using an HDMI cable. Plug the HDMI end into the HDMI port on the back or side of your TV, and plug the power cable into a wall outlet or USB port. Turn on the TV and use the remote to switch to the HDMI input where you plugged in the device.

The Roku device will then go through the same setup process as a Roku TV — it will ask for your WiFi network and password, and offer to create or sign into a Roku account. Once set up, it works the same way as a built-in Roku TV.

The advantage of a separate Roku device is that you can use it on any TV, even one that does not have Roku built in. The disadvantage is that it takes up an HDMI port and requires its own power cable. A Roku TV has both built in, so there is nothing extra to plug in.

Frequently Asked Questions

Do I need a Roku account to watch TV on a Roku TV?

No. You can skip creating a Roku account during setup and still watch content. However, a Roku account makes it easier to manage your apps and settings, especially if you own multiple Roku devices. You will still need separate accounts for streaming services like Netflix or Hulu.

What if I forget my WiFi password?

Check the sticker on your router — the password is usually printed there. If you cannot find it, log into your router's settings from a computer or phone using the router's IP address (usually printed on the sticker as well). You can also contact your internet provider for help resetting the password.

Can I use a Roku TV without connecting it to the internet?

You can watch cable or satellite TV through an antenna or cable box connected to the TV, but you cannot use streaming apps like Netflix or YouTube without an internet connection. The TV itself requires internet to read and run those apps.

Is it better to use WiFi or ethernet on a Roku TV?

Ethernet is faster and more stable if your router is close enough to run a cable. WiFi is more convenient if your router is far away or you do not want a cable running across your room. For most people watching streaming video, WiFi works fine as long as your internet speed is at least 5 Mbps.

Why does my Roku TV keep disconnecting from WiFi?

This usually means your WiFi signal is weak or your router is too far away. Try moving the TV closer to the router, or switch to a 2.4GHz network if your router has both 2.4GHz and 5GHz bands available. If the problem continues, restart both the TV and router, or consider using an ethernet cable instead.
