My LG TV's Wi-Fi connectivity suddenly stopped working, and I'm stumped. Never had this issue before. I reached out to my internet provider, but everything seems fine on their end. Any suggestions on how to fix this?
In your case, if the internet connectivity isn't the issue, then the prime cause would be the device. To reconnect your LG TV to WIFI, you should carry out basic troubleshooting like restarting the TV, resetting the Network Settings under TV Settings, and updating TV firmware if new version is available.
Meanwhile you shall also ensure if you have connected to the right WIFI and moving the router close to your LG TV. As a final resort, you should reset your LG TV and setup again. Check if you can connect to the WIFI and if that fails, then there is a possibility for hardware failure on TV's WIFI module. You can seek help with the LG Customer Support and take your TV for a service.
Let me hear back about which fix has helped you fix the issue !!!
