Fire tv performance using it away from home

i’m using my firetv in my cottage after syncing it at home. How do i now if my router is causing the constant stuttering while watching recordings and live tv? my tablo is hardwired at home and my firetv is hardwired at my cottage. At home the firetv works great. I also don’t get a preview when fast forwarding a show?

Which Quality setting are you using for Tablo Connect? If you have anything but Full Quality, you will not have the preview panes.

Full quality is tough to pull off since it requires a significant upstream bandwidth at your main home.
