Ok. I have all the stuff and have installed the network card in the desktop.

Now, do I need to install the DSL modem & other stuff before I install the wireless router, thingy?

The instructions for the router thingy asks for what kind of internet confirguration type I have and I have no idea. It says that the ISP installer (didn't have one, my Verizon DSL is self install) should have left that info for me at installation.

There's really no info for the DSL, such as a booklet like I got with the wireless router thingy, just an installation CD that has instructions.
