Modern Smart TVs are often taken for granted, but owners of older models or budget devices regularly encounter the lack of a built-in wireless module. The lack of Wi-Fi limits the screen's functionality, turning it into a simple monitor for cable TV or viewing files from a flash drive. However, technological advances make it easy to solve this problem by adding wireless networking to any device with a video input.
In this article we will take a detailed look at What to connect to the TVso it can access the internet without running extra cables. There are several proven methods, from using special USB adapters to purchasing external media players. The choice of a specific solution depends on the year of manufacture of your device, the availability of available ports, and your budget.
Before purchasing additional equipment, it's worth checking your receiver model. Sometimes the module is already built-in but disabled by software or requires activation through the service menu. In other cases, an inexpensive whistle compatible with your device's chipset is sufficient. We'll cover all the details so you can choose the best option for your needs.
Checking the built-in capabilities of the TV
The first step should always be a thorough diagnosis of your existing equipment. Many users mistakenly believe their TV doesn't support Wi-Fi, when in fact the feature is simply hidden or not configured. Carefully inspect the device's casing: the presence of a built-in module is often indicated by a logo. Wi-Fi, Smart TV or an image of the antenna on the front panel or in the instructions.
Access the settings menu using your remote control. You'll need to find the network section. The path might look like this: Settings → Network → Network settings or Menu → Network → WirelessIf you see "Wireless Network" or "Wi-Fi" in the list of available connections, your TV has the module. All you need to do is select your home network and enter the password.
⚠️ Attention: If your TV finds networks but can't connect, the issue may be with your router's outdated encryption standard. Try changing your router's security settings to WPA2-PSK (AES), as older TVs often don't recognize WPA3 networks.
If there's no mention of wireless networking in the menu, it's safe to assume there's no internal receiver. However, don't despair even in this situation. Electronics manufacturers often offer universal solutions that can be connected via available ports. Below, we'll look at which devices can add this feature to your screen.
USB Wi-Fi adapters for TVs
The most straightforward answer to the question "what to connect" is a special USB adapter. This compact device, resembling a flash drive, plugs into the TV's USB port. However, there's an important caveat: Not every USB whistle It will work with your TV. Unlike computers, where the operating system automatically finds drivers, TVs have drivers built into the firmware.
This means that the adapter must be built on a specific chipset supported by your TV model. For example, adapters based on Ralink or MediaTek chips are often suitable for Samsung devices, while LG devices require specific models with an ID. LG Wireless DongleBuying a random adapter at an electronics store will, in 90% of cases, result in the TV simply not recognizing it.
List of compatible chipsets
Many TVs work with adapters based on Ralink RT5370, RT3070, or Mediatek MT7601 chips. However, exact compatibility can only be determined by searching the TV model code on the manufacturer's official forum.
The connection process usually looks like this:
- 🔌 Insert a compatible USB adapter into the TV port (preferably the port marked
INorService, if any, but usually any one will do). - 📺 Restart the TV by turning it off and on using the button on the TV body.
- 🔍 Go to the network settings menu and select search for wireless networks.
- 🔑 Enter your router password and enjoy the internet.
External media players and TV set-top boxes
If finding a native USB adapter for your TV model is impossible or prohibitively expensive, the best solution is to purchase an external Smart TV Box. This is a standalone device that connects to the TV via HDMI and has its own operating system (usually Android TV or tvOS). Essentially, you turn any screen with an HDMI input into a fully-fledged Smart TV.
Devices such as Xiaomi Mi Box, Apple TV or set-top boxes based on Android, have their own powerful Wi-Fi module, often supporting the dual-band 5 GHz standard. This is even better than the built-in features of older TVs, as the interface will be faster and the list of available apps will be wider. You get an updatable system, while the TV's firmware remains unchanged.
Comparison of the main characteristics of built-in modules and external set-top boxes:
| Characteristic | Built-in module (old) | USB adapter | TV set-top box (Android/iOS) |
|---|---|---|---|
| Speed of work | Low | Depends on the adapter | High |
| Application support | Only relatives | Only relatives | Any from the store |
| Wi-Fi frequency | 2.4 GHz only | More often than 2.4 GHz | 2.4 GHz and 5 GHz |
| Ease of control | TV remote control | TV remote control | Remote/Voice/Phone |
Using gaming consoles
Game console owners may not even realize they have a ready-made solution at their fingertips. PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X/S consoles all have built-in Wi-Fi and can stream media. While they don't fully transform your TV into a Smart TV (you can't stream Netflix directly to your TV), they do allow you to display content from your smartphone or computer.
To use this method, both the console and your smartphone or tablet must be on the same local network. Launch the "Media Player" app or similar on the console. Then, on your mobile device, select a video or photo, press the cast button, and select your console. The image will appear on the big screen.
This method is good because it doesn't require purchasing additional hardware if you already have a console. However, it's less convenient for regular use, as it requires turning on the game console every time you want to watch an online video. Furthermore, console interface It is not designed for navigating video hosting sites, which may be inconvenient for older family members.
⚠️ Attention: When using the console as a media server, ensure that access to the device is allowed in the media settings. Sometimes, antivirus software on your PC or router settings can block the console from being detected on the network.
Connecting via smartphone (Screen Mirroring)
Another option that doesn't require purchasing specific Wi-Fi adapters for your TV is to use wireless screen mirroring technologies. If your TV supports the following standards: Miracast, Digital Overlay or DLNA (even without a full-fledged Smart TV, some models have basic support), you can stream images directly from your phone.
To do this on an Android smartphone, open the notification shade and find the "Cast," "Smart View," or "Screen Mirroring" feature. On an iPhone, this feature is called "Screen Mirroring (AirPlay)," but it only works natively with TVs that support Apple AirPlay 2. If your TV is older, you'll still need a set-top box or adapter with AirPlay support for your iPhone.
The algorithm of actions is usually simple:
- 📱 Make sure your smartphone and TV are connected to the same Wi-Fi network (the TV must be connected via a LAN cable or have its own Wi-Fi, which is against the task, so this method only works if the TV has at least some kind of network interface, or via Wi-Fi Direct).
- 📺 Turn on the signal reception function on your TV (often called
Screen Mirroringin the menu). - 🔗 Find the TV in the list of available devices on your smartphone.
- 🖥️ The phone screen will be completely copied to the TV.
It's important to note that when using Wi-Fi Direct (a direct connection between your phone and TV without a router), your phone's internet connection may stop working because the Wi-Fi module is busy streaming video. In this case, videos from online movie theaters may not play, and you'll have to use pre-downloaded files.
Setup and troubleshooting
Once you've decided what to connect to your TV and installed the equipment, manual setup may be required. Devices often fail to obtain an IP address automatically. In this case, you'll need to go to the network settings and select "Manual Setup." You'll need to enter the IP address, subnet mask, gateway, and DNS servers.
Typical values for a home network:
IP address: 192.168.1.150 (the last digits can be any number from 2 to 254)Mask: 255.255.255.0
Gateway: 192.168.1.1 (your router's address)
DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
If you have a connection but the video is lagging or not loading, check your signal strength. USB adapters located on the back of the TV are often shielded by the metal back panel or case, which dramatically reduces speed. In this situation, using a USB extension cable to expose the adapter's antenna to an open area can help.

Frequently Asked Questions (FAQ)
Is it possible to connect a Wi-Fi adapter from a laptop to a TV?
In most cases, no. TV drivers are tailored to specific chip models. A laptop adapter will likely be detected as an "unknown device" or simply won't receive power. The only chance is if the chips match, but that's a gamble.
Does Wi-Fi work via a USB-LAN adapter?
Some modern TVs (especially recent Samsung and LG models) support Ethernet adapters via USB. This allows you to connect an internet cable to the USB port. However, Wi-Fi dongles operate on a completely different principle and require special support in the TV's core system.
Why does the TV see 2.4 GHz Wi-Fi but not 5 GHz?
This is normal behavior for older technology. Modules manufactured before 2013-2015 are physically unable to operate in the 5 GHz band. To use the high-speed band in this case, an external set-top box (TV box) is required.
How do I know which adapter I need for my Samsung/LG?
The best way is to look at the exact model of your TV on the sticker on the back and search for "[TV model] compatible wifi adapter." Enthusiast forums often post lists of proven models with part numbers.
