I know this is a stupid question...but does my

If you are connecting to the Internet via dial-up service, then the answer would be: Yes. You will need either an internal modem or an external PCMCIA card modem to be able to connect to the Internet.
However, if you are using broadband service (like DSL or Cable modem), then you do not necessarily need to have a modem installed.

well according to the specs i saw it already has a wireless lan card, an ethernet card, and a old school phone modem jack, so you should be good. are you having issues connecting to the internet via wifi?
