Most older TVs cannot connect to WiFi without an external device
If your TV was made before 2010, it almost certainly has no WiFi built in. Even many TVs from 2010 to 2015 lack WiFi or have WiFi that no longer works with current networks. The simplest solution is to plug in a separate device — a streaming stick, set-top box, or media player — that adds WiFi capability to any TV with an HDMI port.
The TV itself does not need to be smart. It just needs to display what the external device sends it. This approach costs between $25 and $100 depending on what you want to watch, and it works on nearly every older television made in the last 20 years.
Key Takeaways
- Older TVs without built-in WiFi can use external devices like Roku, Amazon Fire Stick, or Apple TV to stream content over your home network.
- Your TV needs an HDMI port to connect a streaming device, but does not need any smart TV features or internet capability of its own.
- Budget streaming devices cost $25 to $40 and handle basic streaming; premium devices cost $50 to $100 and offer faster performance and more apps.
- If your TV has no HDMI port, you can use an older device like a Roku 2, Chromecast, or used Apple TV from eBay, which may have composite or component video connections.
What external devices actually do
A streaming device connects to your WiFi network and to your TV's HDMI port. The device handles all the internet work — finding your network, remembering your passwords, loading apps, buffering video. Your TV just displays the picture and sound the device sends it. From the TV's perspective, the streaming device looks like a cable box or DVD player.
The device itself is a small box or stick that plugs into the back or side of your TV. It also needs power, usually from a USB cable or a wall outlet. Once it is set up, you use the device's remote to choose what to watch, not your TV's remote.
Which streaming devices work with older TVs
Roku devices are the most common choice for older TVs. Roku makes streaming sticks (which plug directly into HDMI) and boxes (which sit next to your TV). The Roku Express costs around $30 and handles Netflix, YouTube, and hundreds of other apps. Roku Ultra costs around $100 and is faster and includes more features. All Roku devices work on any TV with an HDMI port made in the last 15 years.
Amazon Fire Stick costs $25 to $40 depending on the model. It plugs into HDMI and gives you access to Prime Video, Netflix, YouTube, and other apps. If you have an Amazon account, setup is faster because Fire Stick can use your existing login.
Google Chromecast costs around $30 and works differently — instead of using a remote, you cast video from your phone or computer to the TV. This is useful if you want to show photos or mirror your phone screen, but less convenient if you just want to sit down and watch a show.
Apple TV costs $100 to $200 and is the most expensive option. It is worth it only if you use Apple services like Apple TV+, have other Apple devices you want to connect, or want the fastest performance. For a basic older TV, it is overkill.
TVs with broken or missing HDMI ports
If your TV has no HDMI port — which is rare but happens on very old sets — you have fewer options. Older Roku models like the Roku 2 and Roku 3 had composite video connections (the red, white, and yellow cables). You can sometimes find these used on eBay for $20 to $40. Older Chromecast models also supported older video connections, though they are harder to find.
Another option is a used cable box or media player from the same era as your TV. A used TiVo, Roku, or even an older Apple TV from a thrift store or online marketplace may have the right connections. Test it before you buy if possible, or buy from a seller with a return policy.
If your TV has no video input ports at all — only an antenna connection — it cannot display content from an external device. At that point, replacing the TV is more practical than trying to adapt it.
Setting up a streaming device on your network
Plug the device into an HDMI port on your TV and into power. Turn on your TV and switch to the HDMI input where you plugged the device. The device will show a setup screen asking for your WiFi network name and password. Type in your WiFi details using the remote or an on-screen keyboard.
Once the device connects to WiFi, it will ask you to sign in to your streaming accounts — Netflix, YouTube, Prime Video, or whatever services you use. You can sign in now or skip and do it later. The device is ready to use as soon as it connects to WiFi.
If your WiFi is far from the TV or your signal is weak, the device may buffer or drop the connection. Move your router closer, or buy a WiFi extender (around $30 to $50) to strengthen the signal in that room.
Comparing cost and features
| Device | Typical Price | Best For | Connections |
|---|---|---|---|
| Roku Express | $30 | Basic streaming on a budget | HDMI, power |
| Fire Stick | $25–$40 | Prime Video users | HDMI, power |
| Chromecast | $30 | Casting from phone or computer | HDMI, power |
| Roku Ultra | $100 | Speed and extra features | HDMI, power, ethernet |
| Apple TV | $100–$200 | Apple ecosystem users | HDMI, power, ethernet |
When to replace the TV instead
If your TV is broken, has a very small screen (under 24 inches), or has no working video inputs at all, buying a new TV may cost less than you think. A basic 43-inch smart TV costs $200 to $300 and comes with WiFi built in. A streaming device plus an old TV repair might cost more and give you a smaller screen.
If you already have a working TV and just want to stream, a $30 device is almost always the right choice. But if the TV itself is failing or you are unhappy with its size or picture quality, replacing it solves multiple problems at once.
Frequently Asked Questions
Do I need to pay for WiFi to use a streaming device?
You need to pay for internet service from your provider, but the streaming device itself does not charge a fee to connect. Individual apps like Netflix or Disney+ require their own subscriptions, but the device is just the middleman.
Can I use a streaming device on a TV without an HDMI port?
Not with modern devices. Roku, Fire Stick, and Chromecast all require HDMI. If your TV has composite (red, white, yellow) or component (red, green, blue) connections, look for older used devices like Roku 2 or Roku 3 on eBay. If your TV has only an antenna connection, it cannot accept external video input.
What if my WiFi keeps dropping on the streaming device?
Move your router closer to the TV, or buy a WiFi extender to boost the signal. Some devices like Roku Ultra have ethernet ports, so you can plug them directly into your router with a cable instead of using WiFi. This gives a more stable connection if your router is nearby.
Can I use an old cable box or satellite receiver instead of a streaming device?
Only if you still subscribe to cable or satellite service. If you have already cut the cord, those devices are useless. A streaming device is cheaper and gives you access to more content.
Will a streaming device work on a very old TV from the 1990s?
Only if it has an HDMI port, which TVs from the 1990s do not. Older devices like Roku 2 or used Apple TV with composite connections might work, but finding one in working condition is difficult. At that point, a new TV is usually the simpler choice.
