that will bring it up for you. i haven't put anything in that area for a long time and it's always worked for me. what you might be experiencing is that your /etc/resolve.conf isn't listing your nameservers.
how is it that it doesn't connect? can you see anything? or do you get error messages? i know that in slack it can give you, did me, some problems when things aren't configured just right. off the top of my head i can't remember exactly how i fixed it, but if you still have problems with it, i or another will help you out.
