When to Call a Professional

If you have completed all steps above and your LG TV still shows Error Code 106 — especially if it fails the internal network diagnostic at the Wi-Fi adapter step — the TV's internal Wi-Fi module may be physically damaged or defective. At this point, contact LG Support at 1-800-243-0000 or visit their website to check if your TV is still under warranty. If out of warranty, an authorized LG service technician can diagnose and replace the internal Wi-Fi module. Additionally, if other devices on your network are also having trouble connecting, the issue may be with your router or internet service provider — in that case, contact your ISP for support.

Frequently Asked Questions

What does Error Code 106 mean on an LG TV?
Error Code 106 on an LG TV means the TV has lost its connection to your Wi-Fi network or cannot reach the internet. It is essentially a Wi-Fi disconnection error. The most common causes are a router that needs to be restarted, a changed Wi-Fi password, a weak wireless signal, or a temporary software glitch on the TV.
Why does my LG TV keep showing Error Code 106 even after restarting?
If Error Code 106 keeps coming back after restarting, the likely causes include a weak Wi-Fi signal (try moving your router closer or using 2.4GHz instead of 5GHz), outdated TV firmware, corrupted saved network data (try forgetting and re-adding the network), or in rare cases, a failing internal Wi-Fi adapter in the TV.
Can I fix LG TV Error Code 106 without resetting the TV?
Yes, in most cases you can fix Error Code 106 without a full factory reset. Start by restarting your router and TV, then try forgetting and reconnecting to your Wi-Fi network. Updating the TV's firmware and running the built-in network diagnostic are also effective fixes. A full reset should only be used as a last resort.
Does LG TV Error Code 106 mean my TV is broken?
Not at all — Error Code 106 is a network connectivity error, not a hardware failure message. It simply means the TV lost its Wi-Fi connection. In the vast majority of cases it is caused by a router issue, a Wi-Fi password change, or a temporary software glitch, all of which are easily fixed at home.
How do I connect my LG TV to Wi-Fi after clearing Error Code 106?
Once the error is resolved, press the Settings button on your remote, go to All Settings > Network > Wi-Fi Connection, select your home network name from the list, enter your Wi-Fi password, and press Connect. If you do not see your network, select 'Other Network' to enter the details manually or press the Refresh button to rescan for available networks.
