Raring 3.8 still has problem.  Here's relevant syslog entries from Acer 5253 amd64 notebook.  At 15:23:45 NM decides to disconnect.  At 14:23:50. I started manual connect to hidden network which went through just fine, see the entries.

As a user since Dapper Drake Beta, why has Network Manager decided to deactivate device at 15:23:45??  There are "no new secrets needed" so why does it disconnect anyway?

At 15:24:45 after I started manual connect to hidden network it says.
Jan 12 15:24:47 Aspire-5253 NetworkManager[805]: <info> Activation (wlan0/wireless): connection 'LAUREL' has security, and secrets exist.  No new secrets needed.
then goes right ahead and authenticates.  Why doesn't NM just go ahead and connect like Precise does?  Why didn't NM do the connect at 15:23:45?? instead of me having to do a manual connect?

Thanks for any thoughts, especially any patches to NM to see why it disconnects instead of connecting.
