Hi Angel,
if you want a wireless Keyboard WITH num. pad you have to go elsewhere.
I have a Logitech K800 which is a 1st wireless that is illuminated (that I know of).
You can use it both wired & wireless (when using wireless the light turns off in about 3 secs & comes back when you touch the keyboard.
A 2nd wireless i have is diNovo Edge, also Logitech. This one is the nicest looking keyboard I seen with ¹⁄₈" thick plexiglass top and mouse & volume control slide build-in.
But both these Keyboards are black and little bit expensive...
