Heres what i know mostbroadband cards use the PMCIA port on your computer and have a built in antenna another option which I use is that I have sprint and a phone with a fire wire conntector on it. I use my cell phone as a modem. This is actually cheaper by $10 a month with the unlimited data option. Its $39.99/mo. You can download the device driver at motorola.com. Dont buy the software just download the driver update and set it up thru internet connections.

Which everway you go that should solve your problem.
