Installing Kali to HD

When trying to install Kali via DVD I was not able to connect to the internet via the wireless or the ethernet. While trying to connect via wireless its states the exchange of keys has timed out. When trying to connect via the ethernet it cannot auto config the DHCP. Without an internet connection I am not able to download/install the network mirror. Any advice how on to resolve this issue would be much appreciated. If you need more information please let me know and I'll try to provide more.

have you checked the sha1 for download integrity?..

Have you tried running as live and see if cards are recognized by kernel?..

How are you installing? text? Graphical? from live desktop?

Need more info my friend for community to help you in the best way possible.
