I was getting a different ISP setup today and my internet went down in the early morning hours as a result. My wife was unable to connect to the Tablo to watch her favorite morning show via the LAN. I did some research (scoured these forums) this evening and it should have worked without internet, but didn’t. I did a packet capture of the traffic and it appears that the iPad hits a multicast address and the internet (Tablo API and some AWS servers) before it even attempts to directly connect to the Tablo device. Can someone with more understanding of the data flows explain this to me what is going on and why my wife’s iPad Tablo app wouldn’t connect? Needless to say, my wife was very unhappy (happy wife = happy life…failed).
P.S. It works just fine now since we have gotten the internet re-established later in the day.
Edit: Forgot to mention one probably critical element - my Tablo and other media devices are on a separate subnet from other devices (including the iPad) in the house. Could it be that since the iPad can’t see the multicast broadcast from the Tablo that it then goes to the internet to determine the connection?
