Modern users are accustomed to the convenience of accessing content at any time, but owners of older devices often face limited functionality. The question of how to connect an old TV to a Wi-Fi router wirelessly becomes especially relevant when you want to stream videos from a smartphone or enjoy online cinemas on a big screen. The lack of a built-in Wi-Fi module or Smart TV operating system doesn't mean the device is defective.
There are several proven technical solutions for integrating an outdated TV into a modern digital ecosystem. You won't need to buy new, expensive equipment if you choose the right external receiver or use existing gadgets. In this article, we'll explore all the working methods, from budget adapters to advanced media servers.
Checking for built-in modules and hidden functions
Before heading to the store for additional equipment, it's important to thoroughly diagnose your existing device. Many users don't even realize that their TV already has basic networking capabilities that are simply not activated or hidden deep in the menu. Electronics manufacturers often label such models as Smart TV or Internet TV, but on older panels these inscriptions may not be visible.
Carefully inspect the device's case from all sides, paying particular attention to the back panel and side edges. You need to locate the connector. LAN (network port), which is visually similar to a telephone port but wider, or a logo Wi-FiThe presence of a LAN port does not guarantee a wireless connection, but it does allow for a cable connection, which also solves the problem of the lack of a built-in Wi-Fi module.
Go to the settings menu using the remote control and find the section responsible for the network. It may be called Network, Net or ConnectionIf this section has an option to enable the wireless adapter, you're in luck—you just need to enter your router password. Otherwise, if the menu only offers a wired connection or doesn't have any network settings at all, you'll need external equipment.
⚠️ Attention: Even if there is a Wi-Fi option in the menu, older models (manufactured before 2013-2014) may only support the standard 802.11n and not see modern routers operating in the 5 GHz band. In this case, you'll need to switch the router to compatibility mode.
Older systems' interfaces may differ from modern ones, so finding the right option can sometimes take time. If you've found the network settings but the TV isn't seeing your network, try changing your router's security type to WPA2-PSK, as older encryption protocols are often blocked by updated versions of router software.
Using external Wi-Fi adapters for TVs
If there's no built-in module, but your TV has a USB port, the easiest solution is to purchase a dedicated external adapter. This is a small device, resembling a flash drive, that plugs into the port. USB and receives a signal from the router. However, there's an important caveat: not every USB dongle will work with your TV model.
TV manufacturers use different drivers and chipsets, so an adapter from one brand may not work on a different TV. You need to find an adapter model that is officially supported by your manufacturer. For example, for TVs Samsung Original dongles of the series are often required WIS or WIS09, and for LG — models of the series TWFM.
The installation process usually looks like this:
- 📡 Insert a compatible Wi-Fi adapter into the USB port of a working TV.
- 🔌 Wait until the indicator on the adapter (if there is one) lights up or starts flashing.
- 📺 Go to the network settings menu and select search for wireless networks.
- 🔑 Enter your router password using the on-screen keyboard.
It's worth noting that the data transfer speed via USB adapters on older models may be limited. This won't be a problem for watching Full HD video, but it may cause delays when trying to play 4K content or large files. Furthermore, some adapters require additional power, which the TV's USB port may not provide.
