Hi @Wildfarmrose,
Thanks for reaching us here in the Roku Community!
We appreciate you for flagging us about this issue going on and we'd like to be of support here. This behavior is a bit odd, it's also impossible that this affects the connection along with the DirecTV. You may try another power outlet and see if that makes a difference. If the problem persists, you can check for another power cord and power adapter to confirm if this is an issue along with these connections.
Thanks,
Rey
