OK, I did that and it worked. So what you are telling me, you can't just power up a S3+ miner, you have to go in and reboot it from the web interface. I find it surprising because this is the newest and greatest firmware. Is there a list of bugs somewhere? How is the average miner supposed to know all these things?
This is a bug. Reboot from the web gui and check again
What does it mean when your S3+ has a normal hash rate like 480 Gh/s, but your average is listed as 18 Gh/s? Going crazy over here...
Of the last 3 firmwares, the 12/16 seem to be the best. I know they took it down, but it my early batch S3 up to 500G consistently. I think I will go back to that one. It was better than the 12/19.
it is just a bug where it lost or is using a previous output file due to an unclean reboot... no need to reboot just restart cgminer
/etc/init.d/cgminer restart
Mine do this when there is a power loss...
