Bjorn,
The WIS12ABGNX will only work in in the unit it is connected to. You cannot access two devices at the same time from the same LinkStick.
If your Samsung television does support the Wireless LinkStick option, you can remove it from the Blu-Ray player, but since the Blu-Ray player is newer, you will likely have more Apps on that model.
Thanks for your interest in Samsung products.
