I have two linkstation pro duo. Interestingly the older one LS-WTGL/R1 using the blue interface on fw 1.09 has a shutdown button under maintenance>restart.
The newer one LS-WVL/R1 with red interface had an update not too long ago to fw 1.75 but doesn't have a shutdown button, only restart button. Just wondering if I might have overlooked it somewhere or just SOOL.
