I have several Roku sticks, a Ruku 4, and a Roku 3. No problems steaming with the Roku 3 and 4, but all the Roku sticks have buffering issues. If the Roku stick is having buffering issues because of its wifi antenna, then why are there no issues streaming Netflix, Hulu, Amazon, Plex, YouTube, and Sling TV? It seems to me it would have to do more with the way Tablo buffers if there is no issue with any of the other streaming services. 1080p only takes about 4-8 Mb/s which is not much by today’s standards. The issue still exist even at 720p which uses even less bandwidth.
