I have an older Roku (4200X Roku 3). My Roku players always worked fine back in Houston, but now that I'm in an area of Colorado more remote, and have satellite internet that isn't as great, the playback is horrible on many channels, especially YouTube. However, when accessing YouTube on my phone, which is also hooked to my internet wifi, it plays back just fine. Would getting a newer model Roku help with this? I don't understand why one would work on wifi, and the other won't work nearly as well.
