[lwlan-user]: Tx attempt prior to association problems with DWL-500

When I attempt to access the wireless network I get:
kernel: p80211knetdev_hard_start_xmit: Tx attempt prior to association, 
frame dropped.
over and over and no data ever goes across. The light on the card blinks 
fairly rapidly, which is what it does under Windows when I misspell the 
SSID.

It works just fine under Windows using either of my access points.

I have a D-Link DWL-500 wireless PCI adapter, really a DWL-650 cardbus 
card in a Ricoh RL5C475 cardbus-PCI adapter attempting to talk to either 
an Apple Airport Basestation or SMC 7004WBR wireless barricade router in 
an Intel CA810E motherboard based system. I have RedHat 6.2, updated to 
kernel 2.2.16-3. I installed pcmcia-cs-3.1.24 and then 
linux-wlan-ng-0.1.7.

I checked most of the errors I saw in the mailing list archive, the SSID 
is correct, or at least looks correct. The card works under Windows. The 
cardbus adapter is getting an IRQ assigned to the card. The IP address 
settings look reasonable.

Part of the problem is that there doesn't seem to be any way to debug 
what is happening. I can't find any way to get it to tell me if it 
scanned for an access point on each channel or what happened when it did. 
The Windows control panel shows signal strength, data rate, what channel 
is currently being scanned, and the ID of the access point when found. 
There doesn't seem to be anything equivalent for wlan-ng.

Any idea what I could try next?

I changed

device "prism2_cs"
   class "wlan-ng" module "prism2_cs"

to:

device "prism2_cs"
   class "wlan-ng" module "prism2sta_cs"

in wlan-ng.conf because I was getting module load errors with "prism2_cs" 
being a symbolic link in the modules directory.

The only change I made in wlan-ng.opts was to set

dot11DesiredSSID="cable"

"cable" is the name of my SSID, at least that is what the access point 
says and what I enter into the Windows panel to get Windows to work. The 
access point is on channel 6, but I didn't see anywhere to set that.


This is what shows up in the log when I startup pcmcia services:

I also tried that without the "irq_mode=1", no difference.
