Make sure that the LT has full power on the battery then if you are getting a signal (the little lines ) that should be in the bottom right hand corner come up full and when you put the curser on it comes up connected then it's the LT's signal power is not strong enough to go wireless, also make sure you have it turned on on the keyboard the icon is ((((
If that fail then I suggest you get onto your service provider and explain to them.
