Yes, that is exactly the same string I have.

Here I have a difference as in my case it says:
... Access Point: Not-Associated
And I think that there the problem is shown.
When looking in dmesg it shows eth0 associated with the MAC-address of 
the wireless router but apparently it loses it shortly thereafter.
I think due to the fact it can't get an IP-address.
It's something in the kernel modules that doesn't work correctly.
The problem is that in Hardy it worked although I had to restart the 
network with ifdown eth0, followed by ifup eth0 every time the system 
awakened.
I suspect that in one of the many config scripts something is not right, 
but which one I don't know as I don't know all scripts related to 
networking.
Maybe Derek or Gary has an idea?
