I don't think this is a duplicate of bug #45696. I'm having the same
problem without any suspend to RAM or hibernation actions.
NetworkManager started showing this behaviour right after I ticked off
my Atheros wifi card from the Restricted Driver Manager, just to see
what would happen. Since then, even after adding it back to restricted
drivers manager, *any* wifi card I try eventually gets the same DHCP
release, after which I'm forced to reconnect (~every 1/2 minutes).
After association to *any* AP, there is a communication failure between
the driver and NetworkManager; I can tell, because although ifconfig
returns a proper IP address, the "Connection Information" in nm-applet
shows 0s all around.
I suppose that, because it figures the DHCP didn't provide an IP
address, NetworkManager eventually releases the request. (note that it
remain associated to the AP for a period of time, and only after a few
times does it disconnect from the AP)
I'm running the Gutsy beta on a Toshiba Portege R200.
