Tablo is the new 4-tuner version and I have a Linksys router Model: EA8500. Tablo is connected via Ethernet. All media devices are WiFi. Issue is that my Fire TV and Roku 3 constantly disconnect. During live TV and while while watching a recorded show. I have heard about UPNP and assigning a permanent IP address, but not sure how or if this is the issue. Please help. I have to constantly reconnect.
