    Specs:
    iMac 20
    Snow Leopard and WPA2
    I have just moved an iMac (running Snow Leopard with all the latest
    updates).

    The new location has a Netgear DGN2000N. The wireless network is WPA2
    Personal secured.

    I have a Macbook running Leopard. My Macbook can associate with the
    Netgear / get an address and connect
    My iMac running Snow Leopard cannot connect.

    The only wireless connection I can get to the iMac is if I remove all
    encryption from the wireless network and leave it in the clear.

    What did Apple break with WPA2 in Snow Leopard and how do I fix it ?

    perhaps you need to sort settings in the Netgear.
    Does the Netgear have this enabled?

    If the issue was with the Netgear why would I be getting connectivity from my Leopard / Macbook Pro ?

    There isn't any problem with that. My 3 macs work fine with my WPA2 enabled. Try changing the networks name ad password.

    Only try it to see if it's that. If not you can just revert to the same SSID and pw without a problem.

    Otherwise go to Network PreferEnces, Advance, and delete the network from the list. Allow ur mac to discover the network again.

    My Netgear allows me to add a second SSID which I did. Again my (Leopard) Macbook can connect to it with no issue but my (Snow Leopard) iMac cannot.

    Have tried deleting it and rediscovering it with no luck

    Try this

    From your Macbook to Yout iMac. If it doesn't work, your Airport Card might be faulty.

    NVM it isn't faulty, since you said without security you can connect.

    Did you try Internet Sharing, if so what were the results?

    Yes DHCP is set
    No I did not try Internet Sharing

    I have just discovered that the Snow Leopard Machine can connect to WPA but not WPA2. I have 2 SSIDs from the Netgear.....one set with WPA2 (which can only assign an IP to my Leopard / Macbook) and one set to WPA (which can assign IP to both Snow Leopard iMac and Leopard Macbook)

    WPA-2 SSID (filet) is at the top. See attached

    I tried a couple of other things:

    1. http://osxdaily.com/2007/01/18/airpo...eless-utility/

    With this I collected the following outputs from Terminal:

    bash-3.2$ airport -I
    agrCtlRSSI: -44
    agrExtRSSI: 0
    agrCtlNoise: -94
    agrExtNoise: 0
    state: running
    op mode: station
    lastTxRate: 54
    maxRate: 54
    lastAssocStatus: 0
    802.11 auth: open
    link auth: wpa-psk
    BSSID: 62:22:3f:55:cd:49
    SSID: wii_net
    MCS: -1
    channel: 1

    bash-3.2$ airport -I
    agrCtlRSSI: -41
    agrExtRSSI: 0
    agrCtlNoise: -95
    agrExtNoise: 0
    state: running
    op mode: station
    lastTxRate: 54
    maxRate: 54
    lastAssocStatus: 0
    802.11 auth: open
    link auth: wpa2-psk
    BSSID: 0:22:3f:55:cd:48
    SSID: filet
    MCS: -1
    channel: 1

    filet is the wpa-2 network that my Netgear offers and that my Snow Leopard iMac cannot get connected through
    wii_net is the wpa network that my Netgear offers and my Snow Leopard iMac can get connected through
