    A while ago I upgraded the Airport Extreme card in my first generation Core Duo MacBook Pro to one from a newer MacBook (Pro?) so I could run 802.11n. When holding down option and clicking on the airport menu icon it almost always showed PHY Mode: 802.11n and Transmit Rate as 130. After I updated today it always shows 802.11g and 54. I restarted into my Windows 7 Bootcamp partition and it shows being connected at 130. I have a Linksys e2000 router running DD-WRT. Under OS 10.6.5 the dd-wrt wireless tab reports connecting at 54 mbps and 130 mbps under Windows 7. Does anyone have any suggestions on how I can fix this?

    Here is the information from the Airport tab of System Profiler:
    Interfaces:
    en1:
    Card Type: AirPort Extreme (0x14E4, 0x8C)
    Firmware Version: Broadcom BCM43xx 1.0 (5.10.131.36.1)

    Country Code: US
    Supported PHY Modes: 802.11 a/b/g/n

    Wake On Wireless: Supported

    Thanks!

    Consider yourself lucky if you are able to even connect with your wireless after the 10.6.5 update. It completely destroyed my wireless. I had to reload Snow Leopard from the CD and re-install the 10.6.4 combo just to get my wireless working again.
