The Belkin Wireless G Plus Notebook Card integrates flawlessly with the Belkin Wireless router. You will spend a little more for the Wirless G Plus Card than the traditional card, but the price difference is worth the extra boost you receive. My laptop has never lost a signal, even when far into the backyard. I can travel to the neighbors house and pick up a signal even. Belkin has truly managed to offer a great wireless product for much less than comparable models.
The size of the Belkin Wireless G Plus Notebook Card is about the same as a deck of cards. The card extends 1 1/2 inches out of the side of the laptop. This large size (which is common with notebook cards) is the only con for a mobile person like myself.
All-in-all this is a great product and I would CERTAINLY buy again!
