Welcome and thank you for posting here in the Roku Community, JojoG!
We appreciate you reaching out for support. No worries! We're here to offer some troubleshooting methods to help you connect your Roku streambar to your network connection.
Before we proceed, may we know what TV (model) your streambar is plugged into? In addition, when and where have you purchased this? In the meantime, try to connect your streambar to an alternative network connection to see if it will successfully connect. Perhaps a mobile hotspot would do.
We'll be anticipating your response!
Best regards,
Carly
