I'm very sorry to hear that has happened. In order for me to help you most accurately, please provide the complete model code for this device.
I have bought a Samsung Smarthub.
It refuses to accept the username& p/w printed on its label as valid.
Went to Samsung manual and it suggested a solution using the wireless connection window. I cant find this and I am going loopy trying. For the record I am on my second hub as I exchanged it for exactly this reason.
I could rant about this but the gadget is so promising I just want it to work. Help!
