In some ways you are, however this is what a router does and this what a modem does.

My concern with your issue is did your home or isp service give you a dsl or cable modem ?
IIf you are having problems getting the internet back up, call your isp technical support number.
Also they will have you call dlink so they can let them finish up troubleshooting;
If you want to I suggest you take a picture of your current internet setup front and back,
Atleast that way tman and I or someone else can get a better idea of what you've got and help fix the issue quickly.
