Smart TV unable to connect to Ethernet
4.5
The TV fails to recognize a wired internet connection even when the cable is plugged in.
Symptoms
- "Cable disconnected"
- No IP address
- No lights on LAN port
Possible Causes
- Faulty cable
- Dead LAN port
- Router port disabled
Step-by-Step Fix
1
Check Cable Lights
Look for green/orange blinking lights on the TV or router port.
2
Try Different Cable
Ethernet cables can have internal breaks; test with a new Cat6 cable.
3
Disable WiFi
Some TVs won't use Ethernet if WiFi is already connected.
When to See a Technician
If the LAN port has no lights and a new cable doesn't work, the port may have been damaged by a power surge.
