EX4 intermittent connection

Hi, I was dealing iSCSI drive set up, and yesterday I begun to have another problem.
I’m able to access the drive for a while and then, suddenly the drive goes offline. At the very beginning I thought that it was an isolated problem, but now I 'm having the sam behavior every day.
Anyone else having this issue?
Thanks, regards.

What have you tried so far? What’s your network environment? Did you set a static IP configuration? Are other devices experiencing an intermittent connection as well?

Hi I’ve disconnected all usb drives from my ex4 power down the drive and reconnect again. Whole day with no issues I’ll keep testing to see if this has been the problem. It it hasn’t I will have to mess up with static ip, etc.
