i was previously using the modem router combination from spectrum and my spectrum tv app worked with Roku. I recently exchanged it for just the modem at the Spectrum store and am using my own router which has better range. Upon doing that, I can no longer get the spectrum tv ap to work on my tv's. It works on phone and lap top. I get error code RL-1000 after I input my spectrum user name and password. Ive called support several times and they say they are working on a fix.....Why did it work with Spectrums router and not mine?
You may have to delete the app and reinstall it so it can configure correctly to your personal router.
I have three Roku devices in my house that all work with my personal router.
