I see a previous post from 2015 regarding this issue, but nothing seems to have been changed to address it, now in 2018. This morning I woke up to find my cable modem was not working, and I had lost my internet connection. It was an area outage of Spectrum internet.
I’m not sure on all the details why it didn’t, but I kind of expected my TabloTV to still work on my home network. I know that the PC Browser connect method will fail as it requires the internet to find my TabloTV (this is not the best method, and this has other issues as well, like not working while VPN’d).
I have no understanding of why the Roku Tablo app could not find my TabloTV on my home network which was still up and running. Why does a Roku on my home network depend on the internet to find my TabloTV on my home network? This seems flat out broken to me - this is a completely unnecessary requirement. Other devices on my home network could communicate just fine. I could print. I could get to my NAS files. If my channel guide information (which I agree comes over the internet) ever fully ran out, I would still expect the TabloTV to play the channels, ignorant of the content being shown. This failure today is really frustrating me. I’d like to know if competitive devices have the same limitation.
