MBL 2TB keeps diconnecting my wireless router

Ever since I connected my MBL 2TB anytime I shut down the computer, or if it hibernates, the router will not reconnect. I have to power it down and back up. Please hlep me.

Try checking the sleep timer from the my book dashboard and also for your router.

is your router running dhcp?  Try reserving only one IP address for the MBL.  Or, just set both the MBl and router to use a static IP.
