Big problem with 8.0.100
Hi. Three weeks ago we upgraded our three 5508 controllers from 7.5 to 8.0.100, and since then the controllers (random wich one) suddenly reboots 2-3 times a week. Before upgrade it has been rock solid. 1. Anyone knows when next version of 8.x will be out? 2. Is it possible to downgrade from 8.0.100 to 7.6.130 without any big issues?
