DIAGNOSIS This is a frequent headache with smart appliances. The dryer's Wi-Fi module has a weak signal or can't maintain a stable connection to your home network, often due to router settings or distance.
FIX Start with a reset on the dryer side. 1) Press and hold the Wi-Fi button on the dryer's control panel for about 3 seconds until the icon blinks, which puts it back into pairing mode. 2) On your phone, go into the LG ThinQ app, remove the dryer from your device list, and re-add it as if it were new. Make sure your phone is on the same 2.4 GHz Wi-Fi network (these dryers usually don't support 5 GHz). 3) During setup, ensure the dryer is physically as close to your router as possible, even if temporarily.
IF THAT DIDN'T WORK The issue might be your router. Try rebooting it. Some routers have a "Smart Connect" feature that bands devices between 2.4 and 5 GHz; try turning that off and connecting the dryer to a dedicated 2.4 GHz SSID.
HEADS UP The dryer's Wi-Fi antenna isn't powerful. If your laundry room is far from the router, you might need a Wi-Fi extender. Also, know that connectivity issues rarely affect the dryer's core functions—it'll still dry clothes just fine from the physical panel.
