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
How to Share Your Internet Connection on a Mac | R.Zambrano

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

This made no difference
