Seems like Roku is getting a BUNCH of hits for this same question. For what its worth, I found a very temporary solution. While Roku and smartphone are on the same WiFi, run an internet speed test. As soon as the Upload test begins, Roku wakes up and I can stream again. When the stream inevitably freezes up, then run the speed test again. Generally it lasts about 5-10 minutes. It's rather inconvenient and if Roku doesnt take a serious look into it, I have a feeling many of these Roku streaming devices are headed for the nearest landfill. As I write this, I can only imagine how this news is probably burning up Discord and Reddit. Hope the Roku engineers figure it out soon.
