wifi from cable network

[Cees]

I have wireless internet by cable (TV) My laptops connect with wireless router and after I am connected to the router, I have set up my Broadband Connection. For this last I have to connect up by preset username & password. After this I have connection to the internet. My ipad2 can see the wireless router and contact including security password, but can not connect to the internet by connecting the Broadband Connection. Other wireless systems f.e. starbucks works fine, but at home I can not connect.

I am having same problem, iPad recognizes wifi signal but won't connect to home cable wifi, but works at other places just fine. I know the password is correct because it's working with laptops and other devices.

Someone please help with this if you can
