My Roku device is connected direct to ethernet and not wireless. Is there a way to still use the Roku iOS app that needs to be on a wireless network or do I have to move my Roku device to a wireless network.
As long as your Wifi and your Ethernet connect to the same home network it should work, I think. It wouldn't take long to test and find out.
Yes. In the app, select ‘connect manually’ and it will ask you to put in the full IP address of your Roku.
you can find this in Settings>Network>About
once you’ve entered it, it should connect and you’re good to go
