Hi pscla,
Thanks for posting in the Roku Community!
We understand you're having a problem searching for your cable provider's name since it is not listed. Help is here. If you can't see the cable provider name, you can manually set up your cable by connecting it at the back of your TV. Please follow these steps:
- Connect the coaxial cable from your HDTV antenna to the "Ant/Cable In" connector on the back of your Roku TV.
- Turn on your Roku TV, go to Home, and select Live TV. You can add Live TV by going to Settings > TV inputs > Live TV > Set up information if Live TV is missing.
- Follow the instructions on the TV screen to complete the setup.
If the problem persists, check out this link: How to Set Up the Live TV Input on Your Roku.
Please keep us posted on what you find out.
Best regards,
John
