Thanks for your feedback
We are constantly working to improve the stability and quality of the firmware.
We had a big infrastructure change with the move to R80, and under rare circumstances we had indeed encountered unexpected reboots. R80.20.02 included many fixes, so the majority of the issues were resolved.
in R80.20.05 we again saw a few issues, and we will release this week a new image to fix a these issues.
So, we are committed to deliver a firmware with zero unexpected reboots and will continue to improve the performance, stability and security of the firmware.
thanks again for providing your feedback,
