Hi Hollym,
Welcome to the Roku Community!
I would recommend checking out our Support page for troubleshooting issues here:: How to connect your Roku® streaming device to the internet using Wi-Fi® or Ethernet | Official Roku Support
Furthermore, if the affected device is a Roku Express or Roku Premiere, please note that both devices are only compatible with wireless b/g/n networks on the 2.4 GHz spectrum. Ensure that your router is broadcasting a 2.4GHz Wi-Fi network for the device to connect to. You can check your device model by navigating to Settings > System > About.
Please keep us posted and we'll continue assisting you from there.
Best regards,
Mary
