DHCP fails to obtain IP address using WPA-PSK Wireless Broadcom on CentOS 5.5


I am unable to get DHCP to obtain an IP address once the wireless connection has succeed authentication with the router. I am running CentOS 5.5 on a Dell laptop. I have no problems with a wireless connection when I boot the laptop into XP. I can get a wireless connection on Linux if I disable authentication on the router for the wireless setup. I am using NetworkManager to handle the network setup.
I have tried disabling NetworkManager and manually bringing up eth1 using ifup, wpa_supplicant and dhclient. I get the same results. DHCP is unable to obtain an IP address. Here is the output of some of the network commands.

I think the problem has someting to do with the encryption, but I can't seem to figure out how to change that. Under manual setup iwconfig gives me errors if if try to set the enc or key. Not sure where to set that under NetworkManager.

For future reference, please put long spans of commands or error messages like that in CODE boxes, which makes it much easier to read the post. It should also prevent text from being interpreted as smilies or anything like that, which I see you edited your post to correct already.

As for the problem itself, it seems pretty clear that the WiFi card is failing to properly authenticate with the router when using WPA, which obviously will prevent the system from getting a DHCP lease. None of the information you have provided so far indicates why WPA is failing however.

For starters, you might want to check the kernel logs when you try and enable WPA encryption and authenticate with the AP. You might catch an error message that will give us something to go on.

How do I enable WPA encryption? Is that somethig I need to change in the driver config with iwconfig, or something in the kernel which I need to recompile for?

Here is the snippets from wpa_supplicant.log, and messages when NetworkManager is trying to connect and obtain an IP address.

I notice the Association request to the driver failed from wpa_supplicant.log, also the unknown WMI event in messages.
I don't think the WMI is related to what is going on. It seems to be there at other times, and somtimes not when NetworkManager is doing its thing. The other thing I notice is that dhclient starts and then NetworkManager figures it took too long > 45s, but the time posts only show 1 second elasping.
