Few things are as frustrating in a modern smart home as when your LG washer keeps disconnecting from wifi, rendering the remote features useless. This persistent issue disrupts the convenience of the LG ThinQ app, preventing you from starting cycles remotely, monitoring energy usage, or receiving “cycle complete” push notifications. While LG appliances are renowned for their reliability, their wireless connectivity relies heavily on a stable and properly configured home network environment.
In this guide, we will explore the technical reasons behind these disconnections and provide a step-by-step troubleshooting protocol. By addressing factors ranging from router settings to hardware limitations, we aim to stabilize your connection permanently.
Reasons Why Your LG Washer Keeps Disconnecting from Wifi
To fix the problem, one must first understand the variables at play. The issue is rarely an isolated defect within the appliance itself; rather, it is usually a conflict between the washer’s networking hardware and the modern home environment.
When an LG washer keeps disconnecting from wifi, it is typically due to one of the following core issues:
- Network Frequency Mismatch: The washer is attempting to connect to an unsupported frequency.
- Weak Signal Strength: The laundry room is located in a “dead zone.”
- IP Address Conflicts: The router is failing to maintain a steady address for the device.
- Firmware Bugs: Outdated software on the washer or the router.
- Hardware Failure: A malfunction in the internal Wi-Fi module.
The following sections will detail how to diagnose and rectify each of these scenarios.
Optimizing the 2.4 GHz Frequency Band
The most common culprit for connectivity drops in smart appliances is an incompatible network frequency. Unlike smartphones and laptops that thrive on the faster 5 GHz band, LG washers are equipped with Wi-Fi modules that communicate strictly on the 2.4 GHz frequency band.
The Issue with Band Steering
Modern routers often use a feature called “Smart Connect” or “Band Steering.” This combines the 2.4 GHz and 5 GHz bands under a single SSID (network name). The router then decides which frequency to assign to a device. Unfortunately, routers often prioritize the 5 GHz band, or they attempt to switch the washer between bands dynamically. Since the washer cannot communicate on 5 GHz, the connection drops immediately.
The Solution: Separate Your Bands
To ensure stability, you must force the washer onto a dedicated 2.4 GHz network.

- Access your router settings via a web browser (usually 192.168.0.1 or 192.168.1.1).
- Navigate to the Wireless or WLAN settings.
- Disable “Smart Connect” or “Band Steering.”
- Rename your networks clearly (e.g., “HomeWiFi2.4G” and “HomeWiFi5G”).
- Reconnect your washer specifically to the “HomeWiFi_2.4G” network using the LG ThinQ app.
The 2.4 GHz band provides a longer range and better wall penetration, which is essential for heavy appliances often located behind closed doors or in basements.
Assessing Wi-Fi Signal Strength and Interference
Laundry rooms are notoriously difficult environments for wireless connectivity. They are often tucked away in corners of the house, basements, or garages—locations furthest from the main router. Furthermore, they are filled with large metal appliances, water pipes, and thick walls, all of which degrade radio waves.
Diagnosing Signal Weakness
If your Wi-Fi signal strength is weak at the washer’s location (-70 dBm or lower), the device will struggle to maintain a “handshake” with the router. You can test this by standing next to the washer with your smartphone. Ensure your phone is connected to the 2.4 GHz band and check the signal bars. If you have only one or two bars, the washer likely has even less reception due to its metal casing blocking the antenna.
Reducing Network Interference
Even with decent signal strength, network interference can sever connections. Common sources of interference on the 2.4 GHz band include:
- Microwave ovens (often located near laundry areas in apartments).
- Baby monitors.
- Bluetooth devices.
- Neighboring Wi-Fi networks.
Hardware Solutions
If the signal is verified as weak, software tweaks will not suffice. You have two primary hardware solutions:
- Signal Repeater: Install a Wi-Fi extender or signal repeater roughly halfway between your router and the washer. This boosts the signal specifically for that area.
- Mesh Network: If you are using a mesh network (like Eero, Orbi, or Google Nest), ensure a satellite node is placed within line of sight of the laundry room. However, be aware that some mesh systems struggle with 2.4 GHz IoT devices. You may need to enable “IoT Mode” or “Legacy Mode” in your mesh router’s app to prevent the washer from disconnecting.
Router Settings and IP Configuration
If your signal is strong and you are on the correct frequency, but the washer still drops offline, the issue likely lies within the router settings.
DHCP Lease Time
Routers assign an IP address to devices for a specific period, known as the DHCP lease time. When this time expires, the router attempts to renew the IP. Smart appliances sometimes fail to respond quickly enough to this renewal request, causing a disconnection.
- Fix: Log into your router and increase the DHCP lease time to the maximum allowed (often 7 days or “indefinite”).
Assigning a Static IP
A more permanent solution is to assign a Static IP address to your washer. This ensures the washer always uses the same “address” on your network, preventing confusion during router reboots or power outages.

- Find the MAC address of your washer in the LG ThinQ app (under Device Settings > Network).
- Go to your router’s “DHCP Reservation” or “Static IP” settings.
- Enter the washer’s MAC address and assign it an available IP address outside your DHCP pool range.
Firewall Ports
In rare cases, high-security firewalls may block the ports the washer uses to communicate with LG servers. Ensure that ports 80, 443, and 465 are open for outbound traffic for the washer’s IP address.
Managing Firmware and App Updates
Software corruption or incompatibility is a frequent cause of connectivity loss. Keeping your ecosystem up to date is vital for maintaining the link between your appliance and the cloud.
Washer Firmware Update
LG frequently releases updates to patch connectivity bugs and improve algorithm efficiency.
- Open the LG ThinQ app.
- If the washer is currently connected (even intermittently), navigate to the washer’s dashboard.
- Check for a firmware update notification.
- Do not turn off the washer or the router during the update process.
App Updates
Ensure your mobile device is running the latest version of the LG ThinQ app. An outdated app may fail to interpret the signals sent by the washer, making it appear disconnected even if the washer is online.
Utilizing Smart Diagnosis and Factory Resets
If you have configured your network perfectly and the issue persists, it is time to reset the appliance’s logic.
Performing a Network Reset
You do not always need to reset the entire machine; often, resetting the network module is enough.
- Turn on the washer.
- Press and hold the Wi-Fi button for 3 seconds. The Wi-Fi icon should blink.
- On some models, this disables the Wi-Fi. Press and hold again to re-enable it.
- Open the app and go through the “Add Device” process again.
The Factory Reset
If the network reset fails, a full factory reset (or hard reset) can clear corrupted memory caches that might be hindering the connection.
- Unplug the washer from the power outlet.
- Wait for at least 5 minutes to allow residual electricity to dissipate from the capacitors.
- While unplugged, press and hold the “Start/Pause” button for 5 seconds.
- Plug the washer back in and attempt to reconnect to the Wi-Fi.
Using Smart Diagnosis
LG’s Smart Diagnosis feature is an incredibly powerful tool. It transmits data via sound or Wi-Fi to the LG support center or your app.

- Open the ThinQ app and select Smart Diagnosis.
- Follow the prompts to initiate the diagnosis.
- The results may provide a specific error code related to the Wi-Fi hardware or antenna status.
Hardware Failure: The Wi-Fi Module
If you have exhausted all network troubleshooting steps—separated bands, boosted signal, reserved IP addresses, and updated firmware—and the washer still refuses to stay connected, you may be facing a hardware failure.
The Wi-Fi module (a small PCB board located inside the top panel of the washer) is sensitive to heat, vibration, and moisture—three elements present in abundance in a washing machine. Over time, solder joints can crack, or the component can simply fail.
Signs of a Failing Module
- The Wi-Fi icon never turns on, even after a reset.
- The machine cannot “see” any Wi-Fi networks, even if the router is inches away.
- The connection holds for exactly the same amount of time (e.g., 5 minutes) before dropping every time.
If you suspect the Wi-Fi module is dead, and your machine is under warranty, contact LG support immediately. If the warranty has expired, this is a replaceable part. A technician can swap out the PCB assembly relatively quickly, restoring your smart features.
Conclusion
Resolving the issue when your LG washer keeps disconnecting from wifi requires a systematic approach. It is rarely a sign of a broken machine, but rather an indication of a network environment that needs optimization. By ensuring you are utilizing the 2.4 GHz frequency band, minimizing network interference, and configuring your router settings for IoT stability, you can enjoy the full suite of smart features LG offers.
Remember that smart home ecosystems are complex. A change in your mesh network configuration or a new neighbor’s powerful router can disrupt your settings. Regular maintenance, such as checking for a firmware update and verifying signal strength, will keep your laundry routine running smoothly and intelligently.
Frequently Asked Questions
Why won’t my LG washer connect to my 5 GHz Wi-Fi network?
LG smart washers are equipped with hardware that is strictly compatible with the 2.4 GHz frequency band. They cannot communicate via 5 GHz networks. To ensure a stable connection, you should disable “Band Steering” or “Smart Connect” in your router settings and create a dedicated 2.4 GHz SSID specifically for your smart appliances.
How can I improve the Wi-Fi signal in my laundry room?
Laundry rooms are often “dead zones” due to distance from the router and interference from metal pipes and appliances. If your signal strength is weak, you can install a Wi-Fi signal repeater halfway between your router and the washer. Alternatively, if you use a mesh network, place a satellite node within line of sight of the laundry room and consider enabling “IoT Mode” or “Legacy Mode” in your mesh app.
What is the difference between a network reset and a factory reset?
A network reset is performed by holding the Wi-Fi button for three seconds, which specifically clears the wireless credentials so you can reconnect via the LG ThinQ app. A factory reset (or hard reset) involves unplugging the washer for five minutes and holding the Start/Pause button for five seconds while it is unplugged. This clears the machine’s internal memory caches and can resolve deeper software glitches.
How do I know if my washer’s internal Wi-Fi module has failed?
Signs of a hardware failure include the Wi-Fi icon failing to light up even after a reset, or the washer being unable to detect any nearby networks even when a router is close by. Because these modules are sensitive to the heat and vibration of the laundry environment, they can occasionally fail. You can use the Smart Diagnosis feature in the ThinQ app to check for hardware-specific error codes before contacting a technician.
