Your Network is probably not using the DHCP protocol.

i am trying to install kali from a dvd. I keep getting this error when i install it:
Your Network is probably not using the DHCP protocol.Alternatively, the dhcp server may be slow or some network hardware is not working properly.

I can skip this step from here by simply clicking the continue option, the installtion then goes fine.But then i am not able to use the internet.It shows disconnected at the network option present on the desktop.I badly need my internet to work and i am novice in all this.. so please give me your valuable suggestions.
