Hey,

I just installed centos 7 (newbie) and can't get my ethernet device up and running. I found out that I'm missing the driver and that i need to install the kmod-tulip from elrepo. My question is: how can i download and install something without a connection?

There is no kmod-tulip in ELRepo. Back up a step, what is the output from lspci -nn | grep -i net

The first one of those wants kmod-forcedeth and the second one wants kmod-3c59x, both packages from ELRepo. You'll need to manually download one or both of those packages from their site and transfer it to your machine using a USB stick or some other method like that. Mount the stick and use yum --disablerepo=\* install /path/to/your/usb/stick/kmod-* (suitably amending /path/to/your/usb/stick according to where you mounted it).

I would also recommend installing their elrepo-release package as that will add ELRepo to your list of yum repos and if there are future updates to those packages then you will automatically receive them. That's important if you don't want them to stop working when the next point release comes out as kmod packages often need to be rebuilt for point release kernels (where RH make larger changes than usual).
