Well, the page doesn't tell you the manufacturer or chipset.
It also only indicates 100mbit, it may not work with a cable modem or DSL modem which may be only 10mbit.
Why do you want to buy from cyber rebates in the first place though? It takes a heck of a long time to get the money back, and $219 is a ridiculous amount to loan to cyberrebates for a network card.
Look around places like buy.com, onvia.com, or mwave.com. You should be able to find a 10/100 network card that should work fine with a cable modem or DSL modem. You shouldn't have to spend more than $30 on a decent card, or $50 on some high up brand name.
