I was wanting to upgrade to dual-band N now that I have a router that supports it. I know my laptop uses mini-pci express for the connection and is easy to get at so replacing the existing one seems like the best option so I don't have to worry about a card sticking out. I was wounder if the bcm4321 is a good chipset to get for a wireless card or do you recommend anything else for dual-band N? Also I found a good deal here
but the last time I got something from hong kong on ebay it was a battery that totally was not the mAh they said it was. So was wondering if the batteries are just a problem from hong kong or has anyone else order other things on ebay from hong kong?
