Setting up Wi-Fi on an LG Refrigerator: Instructions for SmartThinQ Models

Modern refrigerators LG with technology support SmartThinQ are turning into full-fledged smart home devices, capable of syncing with mobile apps, voice assistants, and other gadgets. However, without a stable connection to Wi-Fi All this functionality remains unavailable. Setting up a network on a refrigerator may seem unintuitive—especially if you're used to setting up routers or smartphones, where the interface is intuitive.

In this article, we will figure out how to properly connect a refrigerator. LG to a wireless network, what nuances to consider when choosing an encryption type, and what to do if a device doesn't see your router. We'll pay special attention to common errors (for example, Error 2001 or Connection Failed), which often arise during initial setup. And if your refrigerator was manufactured before 2020, check its compatibility with modern standards. Wi-Fi 6 - Some older models may not support new security protocols.

Before you begin, make sure your refrigerator is a series SmartThinQ or ThinQ AI (usually these are models with a touch screen or button Smart on the panel). If there is no logo on the case ThinQ, most likely, there is no wireless connection function. Also, prepare your Wi-Fi network information: name (SSID) and password. If you use a dual-band router, it's better to connect to the network 2.4 GHz - it is more stable for smart home devices.

1. Checking the LG refrigerator's Wi-Fi compatibility

Not all refrigerators LG support internet connection. This feature is only available on models with technology SmartThinQ (or ThinQ AI), which are usually equipped with:

• 📱 Touch display on the door (for example, models LG InstaView or LG Door-in-Door).
