I have random disconnections, from a couple of times / day to 4-5 times / day, the disconnection time vary from 5-6 sec to total loss of connection, I mainly fix the issue by turning the powerline off the on. Well, very annoying issue! There is no newer firmware and the powersave utility simply is not working (error message says can't save)
tech support is PATHETIC , repeating again and again the same questions without any result. thanks in advance for any help/ideas!
