Hi @Itzabelle,
Thanks for your first post in the Roku Community!
We understand that you are facing an issue with the ONN Roku TV that keeps on disconnecting from your home network. We apologize for the inconvenience this has caused and we will work with you to know what went wrong so we can assist you further and fix the issue.
We would like to ask you to attempt to try disabling the "power saving" feature. You should be able to just press Home on your remote a few times to wake the Roku device from power saving or you can disable it under Settings > System > Power > Auto power savings > After 20 minutes of no interaction.
If the issue persists, please refer to the support article here for additional troubleshooting steps: How to connect your Roku streaming device to the internet using Wi-Fi or Ethernet | Official Roku Su...
Please let us know if the issue is fixed or reply back to the thread for further assistance, we will be glad to help you.
Best regards,
Mary
