I'm having trouble getting my network card to work.

I'll repeat that. NO NETWORK (so apt-get update will not work)

in order to build the driver from here: http://www.realtek.com/downloads/dow...&GetDown=false
I need to install the headers.

I've checked here: http://http.kali.org/pool/main/l/linux-latest/

but dpkg wants "linux-headers-3.7-trunk-all-amd64" which I can't find.

help a brother out?

Gigabyte 990FXA-UD5 if it matters.

once this is solved, then on to figuring out why my USB2.0 ports don't work...
