We have no idea what your "dvd player" is. Please give us a model number, we are not the psychic friends hotline here.
With no specific information given, here is my answer
If you are trying to hook up a dvd-rom drive for a computer then you need to use a USB cable.
If this drive is for a desktop then you need a USB-SATA adapter
If the drive is a slim laptop one then you need an external enclosure that will adapt the special ODD SATA connector to USB
If you are trying to hookup a dvd-player like you hookup to a TV then the answer is "you don't"
Your laptop has no form of video inputs, it can not take video in form a source device, it can only output video to a TV or other display.
Your lack of internet has absolutely nothing to do with anything.
