I have a Roku Express, I'm not sure what our "landlord" has upstairs but apparently, ours interferes with his. Is there a way to solve this problem in the settings? He is disabled and not "tech savvy".
Can you define "interfere?" Are you on the same Wi-Fi? Competing for bandwidth? driving each other's Rokus with your remotes? (Hmm, no a plain old Express comes with an IR remote so that seems unlikely.)
We are on the same Wifi. I don't know what he has for a Roku unit though.
