What You Need Before You Start

A Roku device connects to your TV and lets you stream shows, movies, and apps instead of relying on cable or broadcast channels. Before you plug anything in, gather three things: your Roku device (a stick, box, or TV with Roku built in), your TV remote, and your home WiFi network name and password.

Check that your TV has an HDMI port — the rectangular slot about the size of a USB stick. If your TV is older and has only yellow, white, and red ports, you'll need an adapter, which costs $10 to $15 at any electronics store. Most TVs made after 2010 have HDMI.

If you're installing Roku on a TV that already has it built in, skip the hardware steps below and go straight to the WiFi section.

Key Takeaways

  • Roku devices plug into your TV's HDMI port and need power from a USB outlet or power adapter.
  • After plugging in the device, turn on your TV, switch to the HDMI input where your Roku is connected, and follow the on-screen prompts.
  • You will need your WiFi network name and password to connect Roku to the internet.
  • The entire setup takes 10 to 15 minutes and you can start streaming when ready after.

Connecting the Hardware

Plug the Roku device into an HDMI port on the back or side of your TV. If your Roku is a stick, it plugs directly into the port. If it's a box, use the HDMI cable that came in the box. Push it in firmly until you hear a click.

Next, plug the power cable into the Roku device. The cable either goes into a USB port on your TV (if your TV has one) or into a power adapter that plugs into a wall outlet. Most Roku sticks use the USB option; most Roku boxes use a wall adapter. The device will power on automatically once plugged in — you'll see a light turn on.

Turn on your TV using your TV remote. You should see the Roku startup screen appear. If you see your normal TV input instead, press the Input or Source button on your TV remote and select the HDMI port where you plugged in the Roku. The port number is usually printed next to the HDMI slot on your TV.

Connecting to WiFi

The Roku screen will ask you to select your language and then show a list of WiFi networks. Find your home network name in the list and select it. Type in your WiFi password using the on-screen keyboard — use the arrow buttons on your Roku remote to move between letters and numbers, and press OK to select each character.

Roku will take 30 to 60 seconds to connect. Once it does, you'll see a confirmation message. If the connection fails, double-check that you typed the password correctly — passwords are case-sensitive, meaning capital and lowercase letters are different.

If you don't see your network name in the list, your router may be broadcasting on a 5 GHz frequency that your Roku doesn't support. Go back and look for a network name that ends in "5G" or "5GHz" — if you don't see one, your router is probably set to 2.4 GHz already, which Roku uses. Restart your router by unplugging it for 30 seconds, plugging it back in, and trying again.

Creating or Signing Into Your Roku Account

After WiFi connects, Roku will ask you to sign in or create an account. You can use an email address you already have or create a new one just for Roku. This account lets you read apps, save preferences, and use features like remote control from your phone.

If you already have a Roku account from another device, sign in with that email and password. If you're new to Roku, select "Create account" and follow the prompts. You'll need to verify your email by clicking a link Roku sends you — check your email inbox and spam folder.

You can also skip account creation and use Roku in guest mode, but you won't be able to read apps or customize your home screen. Most people take the two minutes to create an account.

Adding Apps and Channels

Once your account is set up, you'll see the Roku home screen with a menu on the left side. Select "Streaming Channels" to browse apps like Netflix, YouTube, Hulu, Disney+, and hundreds of others. Find an app you want, select it, and choose "Add Channel." Most apps are free to read; some require a paid subscription to watch.

After you add an app, it appears on your home screen. You can rearrange apps by highlighting one, pressing the Options button on your remote (marked with a star or asterisk), and selecting "Move." Delete apps the same way if you change your mind.

You don't need to add apps right away — you can do this anytime. Start with one or two you know you'll use, like Netflix or YouTube.

Troubleshooting Common Setup Problems

If your Roku won't turn on, make sure the power cable is fully plugged in at both ends. If it's plugged into your TV's USB port, try the wall adapter instead — some TVs don't provide enough power through USB. Wait 30 seconds after plugging in before assuming it's broken.

If the HDMI connection isn't working, try a different HDMI port on your TV. Some ports work better than others, especially if your TV is older. Also check that the Roku stick or cable is pushed in all the way — a loose connection is the most common cause of a black screen.

If WiFi keeps disconnecting, move your router closer to the Roku or remove obstacles like metal objects or microwaves between them. Roku devices work best within 30 feet of your router. If you have a very large house, you may need a WiFi extender.

Using Your Roku Remote

The Roku remote has five main buttons: up, down, left, right, and OK in the center. Use these to navigate menus and select apps. The back button (arrow pointing left) takes you to the previous screen. The home button (house icon) takes you to the main menu from anywhere.

Most Roku remotes also have colored buttons (red, green, yellow, blue) that some apps use, and a microphone button for voice search. Press the microphone button and say the name of a show, movie, or app — Roku will search across all your installed apps at once.

If your remote stops working, replace the batteries. If it still doesn't work, you can control Roku from your phone using the free Roku app, available on iPhone and Android.

Frequently Asked Questions

Do I need a Roku subscription to watch shows?

No. Roku itself is free — you pay for individual apps like Netflix or Disney+ if you want them. Many apps like YouTube, Pluto TV, and Tubi are free to watch with ads. You choose which services you subscribe to.

Can I use Roku without internet?

No, Roku requires WiFi to stream anything. Without internet, you can only see the home screen and settings. If your WiFi goes down, Roku won't work until it comes back.

What if I forget my Roku account password?

Go to roku.com on a computer or phone, click "Sign In," and select "Forgot password?" Enter your email address and Roku will send you a reset link. Once you reset it, sign back into your Roku device with the new password.

Can I use Roku on multiple TVs?

Yes. Each TV needs its own Roku device, but you can sign into all of them with the same account. Your apps and preferences will sync across devices.

Why is my Roku running slowly?

Restart it by unplugging the power cable for 30 seconds and plugging it back in. If it's still slow, restart your WiFi router the same way. Too many apps installed can also slow things down — delete apps you don't use.
