There is a NZBget mobile android server available. I know thats not sab. but a pretty damn good alternative.

I used to use this a few years ago, but I haven't tried it in a long time. I don't know if it still works, but you might have some luck with it. http://powernzb.co.uk/
Edit: This might be a better choice NZBGet Mobile
What you are looking for is something like NZBget or SABNZBD+. There's this port of NZBget for Android, but no idea if it would work on Shield TV.

I have a Synology NAS that runs NZBget and Sonarr, and streams all my media content to the Shield TV.
Nzbget Mobile is a great android client. I frequently use it when I'm on the road. I then use mx player or SPMC to play.
Install NZBGet Mobile onto your phone and download a 10MB file over both Wifi and Mobile data.
Then you will know whether it is your computer/network or your ISP.
If it is your computer and nothing has changed, RAM failure is frequently overlooked.
