I have been reading that 802.11n is an easy upgrade to do. Well I took a plunge and purchased MA688Z/B from hong kong ebayer. The shipping took whopping 3 weeks. Anyways.. I replaced the current with MA688Z/B and booted up the system. The network utility note the card as Apple vendor and 802.11a/b/g/n and so on. However there seems to be a problem: the current speed is only @ 65mbits. In fact, the card seems to be slower than the previous 802.11g. Has anyone experienced same problem? Is the card faulty? Please share any experience if you have any Any help will be great. Thanks in advance.
