To make your TV wireless, you connect it to your Wi-Fi network so it can stream content from the internet without any cables. The exact method depends on whether your TV is a smart TV with built-in wireless capabilities or an older model that needs an add-on device.
How to make your TV wireless with built-in Wi-Fi
Most modern smart TVs include built-in Wi-Fi, which is the simplest way to make your TV wireless. To connect a smart TV to Wi-Fi, navigate to the "Settings" menu, then "Network" or "Network & Internet," select "Wireless" or "Wi-Fi," choose your network name (SSID), and enter the password using the on-screen keyboard. Some TVs offer Wi-Fi Protected Setup (WPS) for easier connection by pressing a button on both the router and selecting WPS on the TV. Once connected, your TV can stream content from services like Netflix and Hulu directly over your home network.
Add a streaming device to any TV
If your TV lacks built-in Wi-Fi or you want a faster, more feature-rich experience, plug-in streaming devices turn any HDMI-equipped TV into a wireless streaming hub. Devices like Roku, Amazon Fire TV Stick, Apple TV, and Chromecast connect to your TV via HDMI and have built-in Wi-Fi. Chromecast devices plug into an HDMI port and are set up using the Google Home app on a mobile device, allowing you to "cast" content from compatible apps. These devices provide access to streaming platforms and eliminate the need for a cable connection. Setup is straightforward: plug the device into your TV's HDMI port, power it on, and follow the on-screen instructions to connect it to your Wi-Fi network. For smart TVs that lack built-in Wi-Fi, a Wi-Fi adapter that plugs into the USB port can add wireless capability.
Use a wireless HDMI extender for cable boxes and consoles
For source devices like cable boxes, Blu-ray players, or game consoles that you want to place across the room from your TV, a wireless HDMI extender kit is the solution. This device consists of a transmitter that connects to your source device and a receiver that connects to your TV, sending audio and video signals wirelessly without a long HDMI cable. Wireless HDMI extenders can transmit through walls, floors, and other obstacles, with models offering ranges up to 100 feet or 300 feet. This setup is ideal when you want to hide the source device in a cabinet or on a different wall. Note that wireless HDMI extenders can introduce a slight delay, which may be noticeable during fast-paced gaming or live sports, so choose a model with low latency if that matters to you.
Mirror your phone or laptop screen wirelessly
To display content from your phone, tablet, or computer on your TV without cables, use screen mirroring or casting. Apple AirPlay allows iPhone, iPad, or Mac users to stream video, audio, or mirror their screen to an Apple TV 4K or AirPlay-enabled smart TV, requiring both devices to be on the same Wi-Fi network. Samsung Galaxy phones use "Smart View" (Miracast-based) to mirror their screen to compatible Samsung Smart TVs (2016 onward) via the Quick Settings panel. For non-Apple or non-Samsung devices, wireless display adapters like Chromecast or Miracast-based adapters plug into your TV's HDMI port and let you cast or mirror from your device.
Connect directly with Wi-Fi Direct
Wi-Fi Direct allows some TVs, like Sony BRAVIA models, to connect directly to a device for content streaming without needing a wireless router. This is useful when you are away from your home network or your router is unreliable. Your phone or tablet can stream content directly to the TV by selecting the TV from the device's Wi-Fi Direct settings. No password or network configuration is needed, making it a quick way to share videos or photos on the big screen.
The future: fully wireless TVs
Truly wireless TVs that eliminate both video input and power cables are emerging. LG's OLED M3 uses a "Zero Connect Box" for wireless A/V transmission, while the Displace TV runs on rechargeable batteries. These products represent the next step in eliminating all cables from your entertainment setup.
Frequently Asked Questions
Can I make my existing TV wireless?
Yes, using a wireless HDMI transmitter, you can make your existing TV wireless by sending audio and video signals from your source devices without cables.
Will a wireless connection add noticeable latency for gaming?
Streaming devices and built-in Wi-Fi typically have lower latency, but for competitive gaming, a wired HDMI connection is still the most reliable option.
Can I connect wireless audio for my TV at the same time?
Yes, most smart TVs and streaming devices support Bluetooth or Wi-Fi-based audio connections, allowing you to pair wireless soundbars, headphones, or speakers while streaming video wirelessly. Check your TV's audio output settings to enable wireless audio for your TV.
Do all streaming devices work with any TV?
Any TV with an HDMI port can use a streaming device like Roku, Fire TV Stick, or Chromecast. For older TVs without HDMI, you may need an adapter, but the device's wireless streaming capabilities remain the same.
Can I make an older TV wireless without HDMI?
Yes, you can use a wireless display adapter that connects via composite or component video ports, or use a streaming device with an HDMI-to-composite converter. The wireless functionality is still provided by the adapter or converter, not the TV itself.
Is it safe to leave a streaming device plugged in all the time?
Yes, streaming devices are designed to be left plugged in. They enter a low-power standby mode when not in use, and many include automatic updates and sleep timers to manage power consumption.
