I am having the same problem. I just recently purchased my laptop from work. It was reset to factory standards and all company info was deleted. Other laptops in my house connect.
Connecting to the internet
I have a linsky router for my wireless and it works on other laptops throughout my apt. However on my laptop when i try to connect to my network and i entered my network key (which i created myself) it does not work. I used the same key on other laptops and it worked so what is wrong with my computer?
