No internet Connection while installing from software centre indeed it is there

[Nishant]

My internet is working properly though whenever i try to install any software from software center i am given a error msg saying check ur internet connection and following that another msg is shown that "The action would require the installation of packages from not authenticated sources" and i makes me to close it and finally installation fails , i received that msg when installing from sources other that software center . I would like to add that i recently downloaded Ubuntu 11.10 64-bit and have installed with Windows-7 Ultimate 32-bit as "software" in Win7 from options given to choose how to install Ubuntu while installing from CD. Thanks
