Tablo is connected

Got it worked out, pretty much need to open a support ticket

Did you turn surround sound on in the tablo settings. If so does your roku support surround sound/

When using WiFi is you firestick and phone connect to the same subnet as your tablo.

Are you talking about a network quad or a HDMI quad. You won’t have you firesticks connect to the routers guest wifi.

Sounds like you need to open a help ticket and let tablo support sort this out.
