Comment:

 There is something funky going on on the 1cc wireless network.

 I had trouble last week (Monday), with my conventional HP laptop, and had
 to fall back to the wired network.

 Wad reports very short DHCP leases and getting different IP addresses on
 subsequent associations (indicating the DHCP server is reusing addresses).

 Something is sending unicast packets, waking up suspended laptops
 (arguably a denial of service attack on our batteries; we need to think
 better about wakeup policy).

 And I certainly saw Kim's problem as documented above.

 We have packets from other SSID's appearing in our datastream
 from the device (e.g. cscott's RADV bug).

 Lots of things are stinking in this part of Denmark.

 Having said all this, I agree entirely with needing "all hands on deck"
 from the wireless ether, firmware on up through NM and Sugar, if we're
 going to diagnose what's happening. What is happening is certainly causing
 essentially complete failure at the user level.  We don't have time to do
 serial debugging, but need to get everyone possible to the same location
 for debugging where we are seeing these problems.
