I just received my My book live network drive. Can I connect this to a hub off my router (not the wireless router) and still be able see it wirelessly on all my other laptops or does it have to be connected to the wireless router?
You should always connect your NAS devices to the primary router when possible. While using a Hub or Switch is possible, it increases the likelyhood of issues cropping up (the drive not showing up, speed issues, etc.)
if you’re really using a hub you should’t get problems because a hub sends all input from any line to all the output lines. If you’re using a switch there is a greater probability to get errors. I’ve tried nearly a dozen (gigabit) switches to find one which really made no problem using UPnP.
