Hello! @bluea12,
Thank you for posting in the Roku Community!
Connecting to the internet is important for your Isignia Roku TV to function, particularly when utilizing an ethernet connection. We're happy to help.
It looks like that it will require some assistance from our friends at our hardware partner support to help diagnose your TV hardware. Each TV manufacturer provides direct support for their TV models.
You can find their support options here Insignia Support or at 1-877-467-4289
For improving your WiFi connection, please check it here: How to improve the Wi-Fi or wireless internet connection to your Roku streaming device
Thanks,
