I bought an HC2 about a month ago. It worked well except that the file system occasionally changed to read-only. When this would occur, I just forced the system back to read-write and it seemed to work again.
Then, about a week ago, my router no longer detected the unit. As it detects other clients on the same hub, I suspect the HC2 is no longer communicating.
I tried several clean flashes of several different SD cards along with several reformats of the hard drive, but to no avail. When I power-up a newly-flashed card, the red LED comes on and stay son. The blue also comes on for about a second, then goes out, stays out a minute or so, then does two double-flashes, about one second apart, then goes off for good. The green initially comes on, but eventually goes out.
I used the default application on Ubuntu 16.04 to do some of the flashes, as well as Etcher on others. I have used files from several sources, including https://sourceforge.net/projects/openme ... z/download. All produced the same result.
At this stage, I am about to conclude that the hardware has failed and send the unit back for replacement. However, as I am new at this, before I take that action, I want to know if anyone in the community has had simulator problems and, if so, what they were caused by.
Thank you.
