Some devices may have an issue being able to connect to the internet when WPA3 is enabled on the Eero.
In the Eero app, try going into the Labs section and then the Discover Tab and disable the WPA3 setting.
Then restart both the Eero and the Roku devices again and see if any change.

------
If the above does not resolve issue, go into the Home, then Devices tab and see if you have allowed internet access to the Roku devices. (verify not paused/blocked).
