When choosing a new TV, you've probably come across a mysterious phrase in the specifications: Wi-Fi support is optionalWhat does this mean—the module is there, but you have to buy it separately? Or is it missing altogether, and the manufacturer is simply skimping on the packaging? Why do some models come with Wi-Fi out of the box, while others require additional clarification?
In practice, this wording often misleads buyers. Depending on the brand and sales region optional Wi-Fi may mean:
- 📦 The module is included but not activated. - requires enabling in settings or updating firmware.
- 💰 The module is sold separately. — you can purchase it and install it yourself (or in a service center).
- 🌍 Market dependence — In some countries, Wi-Fi is included in the basic package, in others it is not.
- ⚙️ Hardware readiness — the TV technically supports the module, but it needs to be purchased separately.
In this article we will analyze all the nuances optional Wi-Fi on TVsWe'll provide examples of models with this feature, explain how to check for the module's presence, and offer recommendations for choosing one. We'll also answer the main question: Is it possible to save money by buying a TV without Wi-Fi and then adding it yourself?
1. What does "Wi-Fi optional" mean? Definition of the term
Phrase optional in technical specifications means that the function is not mandatory and may vary depending on:
- 📌 Sales region — for example, in Europe Wi-Fi may be standard, but in Asia it may be an option.
- 🏷️ Model modifications - the same TV can be released in different versions with Wi-Fi And without him (For example, Samsung UE50TU7000UXRU vs. Samsung UE50TU7000UXZE).
- 🔧 Plant configurations - some manufacturers (for example, TCL or Hisense) save on components for budget lines.
It is important to understand that "optional Wi-Fi" ≠ "no Wi-Fi at all"Most often this means one of three things:
- The module is installed but not activated. - it must be enabled in the service menu or through the firmware.
- The module is missing, but there is a connector for connection - you can purchase and install an external adapter (for example, USB Wi-Fi dongle).
- The module is missing, but the TV supports it in hardware — soldering or replacement of the motherboard is required.
⚠️ Attention: Some brands (eg. LG or Sony) optional Wi-Fi can be linked to serial numberBefore purchasing, check the configuration with the seller using the model code - sometimes the difference is just one letter (for example,UXvs.UZ) means the presence or absence of the module.
2. How to check if your TV has Wi-Fi
If you have already purchased a TV with the mark optional Wi-Fi, the first thing you need to do is find out if the module is installed. Here 4 reliable ways checks:
Method 1: Via the settings menu
Go to:
Settings → Network → Network settings → Wireless network (Wi-Fi)
If the point Wi-Fi no, but there are Ethernet or Wireless network (no module) - this means that there is physically no Wi-Fi.
Method 2: By model and serial number
Look for a sticker on the back of your TV that states:
- Models (For example, Xiaomi Mi TV 4S 55").
- Serial number (For example,
G7LPSS123456).
Then check the complete set:
- 🔍 On official website manufacturer (in the "Specifications" section).
- 📄 In documentation (instructions, device passport).
- 🛒 On seller's website (the differences between modifications are sometimes indicated on the product card).
Find the sticker on the back of the TV
Write down the model and serial number
Check on the manufacturer's website (section "Specifications")
Check with the out-of-the-box documentation
Check with the seller (if the purchase is new)-->
Method 3: Physical examination
Unplug the TV and inspect:
- 📡 Wi-Fi antennas - usually located on the back panel (small plastic "horns" or metal strips under the cover).
- 🔌 Connectors - some models (for example, Samsung QLED 2020–2022) have a slot for connecting an external Wi-Fi module.
Method 4: Through the service menu
For advanced users: enter the engineering menu (button combinations vary by brand) and check for the presence of a Wi-Fi chip. For example, for LG:
On the remote control: Menu → 1147 → OK (enter quickly)
In the section Network or Wi-Fi Info It will indicate whether the module is detected.
⚠️ Attention: Not all TVs support the installation of an external Wi-Fi module! For example, budget TCL models often have soldered connectors, and you can only add Wi-Fi through USB adapter (but this will limit the functionality of Smart TV).
3. Is it possible to add Wi-Fi to a TV if it doesn’t have one?
If the check showed that there is no Wi-Fi module, don’t despair – there is one 3 ways connect the TV to the network wirelessly.
Method 1: External USB Wi-Fi adapter
The easiest and cheapest option is to buy USB Wi-Fi dongle (For example, TP-Link TL-WN725N or Edimax EW-7811Un). However, there are some nuances:
- ✅ Works with most Android TV And Linux-based televisions (for example, Xiaomi, Philips, Sony Bravia).
- ❌ Not supported Samsung Tizen And LG webOS - these OS block third-party adapters.
- ⚠️ Can limit speed (maximum
150 Mbpsfor most adapters).
Method 2: Powerline Adapter (PLT)
If the router is far from the TV and you don’t want to run a cable, use Powerline adapters (For example, TP-Link AV600). They transmit the Internet through electrical wiring:
- 🔌 One adapter connects to the router, the second to the TV (to a power outlet and via Ethernet).
- 📶 Speed up to
600–1200 Mbps(depends on the quality of the wiring). - ⚡ Works even through extension cords (but not through surge protectors!).
Method 3: Installing the indoor module
For advanced users: If your TV has a Wi-Fi module slot (for example, M.2 or proprietary slot), you can:
- Buy an original module (for example, for Samsung —
BN94-03647A). - Disassemble the TV and install it on the motherboard.
- Flash the TV (sometimes you need to update the software to recognize the module).
