I have a BlackBerry Curve 9330. It's no longer used on our plan ( it has no service) but I would really like it for emails. First of all when I scan for networks mine wont come up. I know my network is working because my iphone and laptops and xbox is on it fine. When I manually set up the wifi and put my password in and all that, it says connecting..... then BOOM! the message that pisses me off comes up! It says "Failed to authenticate against the network". Someone please help me! It will be greatly appreciated. by the way i have sprint
