Why should it be so hard to make this thing work as it was supposedly designed to work?
That’s hard to answer, as I think most people would say that it DOES work as it’s supposed to. I’ve seldom encountered issues like you describe, and I’ve been using my Hub constantly since it first started shipping.
Those kinds of things are very hard to pin down if it’s not reproducible by the developers.
Tons of people have encountered the issue, specially in the middle of the 2.x updates. Most solutions seem to be “take it off the network” or “disconnect whatever NAS you have on the network”.
Anyway I just reset it to factory defaults again and it looks to be OK.
If it freezes and restarts itself, there’s no solution other than replacing it.
When I got mine, it worked perfectly well for the first 3 weeks. Then started freezing or just restarting itself. I initially thought it was the file format or something else with the files, but what started as a random issue, then became more and more frequent. I followed all the troubleshooting process with the service desk, it fixed temporally the issue but problems came back after acouple of days. The final solution was just send it back and get a new replacement.
