A warm welcome here in the Roku Community, 420time.
We appreciate you reaching out for Support. We'd be more than happy to assist you with this.
Initially, could you please let us know when your device started to lose its network connection? Are you somehow using a VPN?
We suggest resetting your network settings by navigating to your Home screen. Scroll up or down to select Settings > Advance system settings > Network connection reset > Reset connection to clear the data of your Wi-Fi. After doing so, please try to connect again.
In addition, if you still can't connect to your Wi-Fi after resetting, kindly try to use an alternative network connection, such as a mobile hotspot, to see if it will come through.
Furthermore, we also recommend reaching out to your internet service provider to reboot your network on their end.
Please let us know how it goes, as we are more than eager to help you fix this.
Best regards,
Carly
