nice cafe with wireless in Staten Island?
You also might try Every Thing Goes cafe. It's on Little Bay St., near Forest Ave. They are run by the Ganas people, and are pretty friendly. It's actually also a used bookstore that seems to have a good selection. I'm pretty sure they have wi-fi.
Check their website at www.etgstores.com.
Try The Cup! It is an independent coffee house on Van Duzer Street in Stapleton. This website is outdated, but should give you the address details you'd need: http://www.muddycup.com/mudlane/
There is also Perking Latte on Castleton Ave.: http://www.perkinglattecafe.com/
Enjoy! Miss P.
