It's hard to imagine a modern television without internet access, as it transforms a regular screen into a multimedia center with online cinemas and streaming services. However, owners of older models or budget series often encounter a frustrating situation: the built-in Wi-Fi module stops working, the signal is extremely unstable, or even disappears entirely. At this point, the need for an external receiver arises, and a veritable maze of technical nuances begins to unravel.
The main difficulty is that LG TVsLike any other complex electronics, TVs are tightly coupled to specific hardware components. The webOS operating system installed on most modern models only contains drivers for a specific list of chipsets. This means that a randomly purchased USB adapter is likely to be a useless piece of plastic, as the TV simply won't be able to "see" it.
In this article, we'll discuss how to choose the right device, whether it's worth pursuing original accessories, and what alternative methods exist for establishing a wireless connection. You'll learn about the technical specifications that affect speed and understand why universal solutions in the world of Smart TV are virtually nonexistent. Careful study of the specifications before purchasing will save you time and nerves.
Compatibility and driver issues in the LG ecosystem
The main reason why you can't just buy any WiFi adapter at your local electronics store, is rooted in the operating system's architecture. Unlike Windows computers, where drivers are often installed automatically or downloaded from the manufacturer's website, webOS There is no option for manual driver installation by the user. All necessary files are already "hardwired" into the TV's firmware at the factory.
If you connect a device whose chip isn't listed in the system database, the TV will ignore its presence. Furthermore, even adapters from LG itself, manufactured for different years and series, may be incompatible. For example, a module from a 2014 model may not work on a 2016 TV, despite the USB port appearing identical.
⚠️ Attention: There's no way to "trick" the system and force an unsupported adapter to work by reflashing the firmware or changing settings in a hidden menu. Attempts to download drivers for the USB adapter from the internet to a flash drive are also doomed to failure, as the TV's OS has no mechanism for installing them.
That's why the only guaranteed way The only way to ensure compatibility is to use devices officially approved by the manufacturer for your specific TV series. A list of compatible models can usually be found in the user manual or on the official support website by entering the exact model number of your TV (e.g., 43UM7100).
Original LG adapters: models and series
LG produces its own wireless modules that are guaranteed to work with their devices. These are typically small devices that plug into a USB port, although there are also models that require a special port on the back panel (usually marked as WIFI/WIRELESS or WIFI ONLY). The most common series is the ruler AN-WF.
The most popular and widely supported device for a long time was the adapter LG AN-WF500It supported Wi-Fi Direct and NFC standards, and operated in the 2.4 GHz and 5 GHz bands. However, it's important to understand that even this "universal" soldier isn't compatible with all models. Older TVs (2010-2012 series) may have used other modifications, such as AN-WF100 or AN-WF300.
Below is a table showing the approximate compatibility of popular adapter models with TV series (data may vary depending on the region and specific board revision):
| Adapter model | Supported standards | Sample LG TV series | Connection type |
|---|---|---|---|
| AN-WF500 | Wi-Fi Direct, NFC, 802.11 a/b/g/n/ac | LB, PB, UB, UF, UH, UK (2013-2018) | USB |
| AN-WF100 | 802.11 a/b/g/n | LE, LV, LW, PM (2010-2012) | USB / Dedicated Port |
| AN-WF300 | Wi-Fi Direct, 802.11 a/b/g/n | LA, LN, PA, PN (2012-2013) | USB |
| AN-WF600 | 802.11 ac (Wave 2) | UM, UM7100, UM7300 (2019+) | USB (specific) |
When purchasing an original adapter on the used market (such as Avito or eBay), be sure to check the photos of the device. The casing should have markings that match the recommended ones for your model. Also, check the condition of the plastic casing for cracks and signs of overheating.
Third-party USB adapters: myths and reality
You can find a lot of advice on the Internet about chip adapters that are suitable for LG TVs. Ralink (eg RT5370) or MediatekIndeed, earlier versions of webOS firmware and older LG Linux builds sometimes included such support. However, with the release of newer versions of the operating system (starting with webOS 3.0), the list of supported third-party chipsets was drastically reduced or completely closed.
Trying to use a cheap Chinese adapter from AliExpress that promises compatibility "with all TVs" leads to disappointment in 95% of cases. The TV might even light up the USB port (indicating power is being supplied), but the wireless connection option won't appear in the network settings menu. Furthermore, using low-quality adapters can overload the USB port and, in rare cases, damage the motherboard.
⚠️ Attention: If you still decide to experiment with third-party adapters, look for models strictly based on the chipset
Ralink RT5370This is the most likely candidate for working with older LG models (produced before 2014-2015). For modern models (2016+), the chances are close to zero.
There's also a category of adapters marketed as "Smart TV adapters." These are often the same original LG modules, but resold under a different brand at a premium. Always check the visual design and model number against the official photos on the LG website.
Why don't TP-Link or D-Link adapters work?
These manufacturers produce excellent PC devices, but their drivers are written for Windows, Linux (desktop builds), or Android. The webOS operating system has a closed architecture, and drivers for these chips are simply not built into it.
Alternative solutions: when the adapter cannot be found
It's possible that the original adapter for your TV model has been discontinued, is impossible to find, and is unreasonably expensive on the used market. In this case, there's no point in chasing the "holy grail." There are more modern and often cheaper ways to upgrade your TV to Smart TV functionality or simply ensure a stable internet connection.
The first and most reliable option is to use LAN cableIf the router is in the same room or there's a wire available, this will provide maximum stability and speed, often exceeding the capabilities of the TV's built-in Wi-Fi module. To do this, simply connect an Ethernet cable from the router to the port. LAN on the back of the TV.
The second option is to use external media players. These are devices like Apple TV, Android TV Box (e.g., Xiaomi Mi Box, Nvidia Shield) or Amazon Fire TV Stick. They connect via HDMI and have their own operating system, which is often faster and more functional than the one built into older TVs. These set-top boxes have their own powerful Wi-Fi modules and support all modern standards.
☑️ What should I choose instead of an adapter?
The third option is to share your internet connection from your smartphone. You can use your phone as a Wi-Fi hotspot, but this isn't always convenient due to data usage and battery drain. A more advanced option is to connect your phone to the TV via USB (USB Tethering), but not all LG models support this feature and require configuration on the mobile device.
Diagnostics and connection setup
If you've purchased the appropriate adapter, installation is usually straightforward. Insert the device into the USB port (or dedicated port), wait for the connection message to appear on the screen, and then go to the settings menu: Settings → All settings → Network → Connect to a Wi-Fi networkThe system should automatically find available networks.
In some cases, a TV software update may be necessary. If the built-in Wi-Fi module is unstable, try updating the firmware first via a LAN cable or from a USB drive, downloading the file from the official website. Driver issues can sometimes be resolved with manufacturer patches.
When setting up, pay attention to the signal frequency. If your router is dual-band, try switching from 2.4 GHz to 5 GHz (or vice versa). The 5 GHz band provides speed but is less effective at penetrating walls, while 2.4 GHz has a longer range but is susceptible to interference from neighboring networks and microwave ovens.
⚠️ Attention: The menu interface of LG TVs may differ depending on the webOS version. If you can't find the item you need, use the settings search (magnifying glass icon) or refer to the user manual for your specific model, as the layout of the items varies.

Comparison of connection options: solution table
To make a final decision, let's compare the various internet connection options available on your LG TV. Each has its own advantages and disadvantages, depending on your specific situation, budget, and TV model.
| Method | Price | Stability | Difficulty of setup | Recommendation |
|---|---|---|---|---|
| Original LG adapter | High / Medium | High | Low (Plug & Play) | For those who want to keep the native interface |
| LAN cable (Ethernet) | Low | Maximum | Low | Best choice if there is a possibility of laying |
| Android TV set-top box | Average | High | Average | To revive old TV models |
| Third-party USB (Ralink) | Low | Low / Risk | High (lottery) | Only for experienced users of older TVs |
In summary, finding a WiFi adapter for your LG TV is a precision task. Choosing the wrong model will only lead to wasted money. If you can't find the original module, don't despair: external set-top boxes are often an even better investment, as they not only provide internet but also significantly expand your TV's functionality, adding support for new codecs and apps that your old Smart TV can no longer handle.
Can a Wi-Fi repeater be used as an adapter?
Theoretically, some advanced repeaters (signal boosters) have a "Client" or "Adapter" mode, turning them into Wi-Fi receivers that distribute internet via a LAN cable. Connecting such a repeater to your TV via a cable will provide a wireless connection. However, this requires configuring the repeater itself via a computer and doesn't work with all router models.
Will a Samsung adapter work with an LG TV?
No, it won't work. Each manufacturer (Samsung, Sony, Philips, LG) has its own driver and operating system architecture. Samsung adapters only work with Samsung TVs, and LG adapters only work with LG TVs. There are no exceptions to this rule for the general consumer.
Why does the TV see the network but not connect?
There could be several reasons: an incorrect password, incorrect date and time settings on the TV (check the time settings), outdated router or TV firmware, or a full list of connected devices in the router. Also, try changing the Wi-Fi channel in the router settings to 1, 6, or 11.
Is it possible to flash the adapter to make it work?
No. As mentioned earlier, LG TVs don't have a user interface for installing drivers (.ko files) from a flash drive. Flashing the adapter itself won't help either, as its chipset must be natively supported by the TV's operating system kernel.
Where can I find the exact compatible adapter model for my TV?
Visit the official LG website, find the "Support" section, and enter your TV model (found on the sticker on the back). Go to the "Accessories" or "User Manual" section. The manual often lists the exact part number of the compatible module.
