I'm about to get a new modem and a wireless router. I'm considering the Motorola SB6120 cable modem and than a "n" wireless router....Linksys WRT160N or Belkin Wireless N+ or maybe a D Link 655. I have an oem airport card in my G5, think that it only works on "a" and "b" standards and I'd dearly love to move up to "g" and "n". I've seen a usb dongle that is a "n" wireless adapter (http://rokland.com/store/product_info.php?products_id=317) that might do the trick. Disable the oem airport card (remove it) and then plug this into a usb port. BTW, am running Leopard. Is this possible? Workable? Or do I have to just settle for what I've got? thanks in advance
