Welcome to the Roku Community!
I will do my best to assist you with any wireless network issues and inquiries. As a first step, I would recommend taking a look at our Support page for more information regarding How to find your wireless network name and password | Official Roku Support
In addition, if you are getting an error code or message, refer to this link for common Roku error codes and their recommended actions: How to connect your Roku® streaming device to the internet using Wi-Fi® or Ethernet | Official Roku ...
