I'm seeing the same error in dmesg with a non-encrypted network. I'm connecting using NetworkManager and its vpnc plugin.
The first time I boot up, it connects fine to both and I'm able to use the connection for a few minutes. Then the message:
ipw2200: Failed to send SYSTEM_CONFIG: Already sending a command.
appears 5-6 times in dmesg and the connection drops. NetworkManager still shows that I'm connected to both the wifi network and the VPN, but I'm unable to communicate on the network.
If I disconnect and reconnect to the VPN in NetworkManager, it works fine and doesn't seem to drop out anymore.
I had a similar problem in Fedora 9 (messages from ipw2200 and dropped wifi/VPN connections with no obvious error), so it definitely could be something with the driver.
