Hi @Adub123
Thanks for the post.
Could you tell us if you are getting an error code or message? What Roku model device are you using? Refer to this link for common Roku error codes and their recommended actions: What should I do if I cannot connect to my home network or the internet?
Furthermore, if the affected devices are Roku Express or Roku Premier, please note that they 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 or underneath the player itself.
Keep us updated.
All the best,
Kariza
