are they new? I have never seen one before.
Anyways, the sad fact of the matter is that this hub along with the shub are both made by Netgear with VMs firmware. You'll find a tonne of threads with peeps complaining about routers falling over when they try and connect consoles to it. It sounds sad but I am just wondering whether your tv and consoles trying to connect to it at the same time are too much for it to handle. I know Samsung stuff has it's own media sharing software it uses to try and play/share stuff across the network so I don't know if it is constantly sending messages out trying to detect devices or what.
You arent going to fix the problem and I suggest the following:
1) ring VM up and moan that your router is broken and ask for a new one
2) they'll send you a shub which you can try but i doubt it will be any better
3) put the shub in modem mode and buy a proper router for £50 which will work (don't invest in a shub 2). Have a read of this
