Could you provide a few more details on the issue you're having? 

What happens when you try to use it, what aspect of the hotspot isn't working? Connecting to it? Starting it? Getting access to the internet when already connected?

Answers to any of these and providing more information will greatly help in assisting in getting it working for you!
