Wireless Problem or my Problem?

 I've been trying to use my wireless card, I keep installing it and uninstalling it.

The  www.laptopspark.com says that everything is working fine after hearing my question. The staff told me  to press fn+11 to turn it on and everything goes well after I do as that. Oh, It is my problem.
