Why Can't I access Mybook Live when computer off?

Hello,

I searched the forum, but cannot find any direct addressing of this issue.

Basically I am fully set up, no problems with access from any device, remote access is on, blah blah, but as soon as my computer is off, the drive is unavailable.

I would like simple directions on how to enable access independently of my computer being powered on or off.

If I did miss it if someone could kindly redirect me to the link

Thanks to any who know.

Do you have the my book connected to your computer or to your router? 

To my router. Sometimes I can get in just fine but when I am remote and the computer has been inactive I get error code 905

The computer shouldn’t have anything to do then. Check if the link below helps.
