This is a rare problem.  I think I've seen this happen a couple of times in 
the last several months.  In that time, the kernel has updated more than once.
I could switch to upstream kernel, though again I suspect upstream would 
update more than once before I would see a recurrence.

Is it still useful to test upstream for something that occurs so rarely?

Thanks

Title:
  Intel wireless fails to connect after wake from sleep

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Once in a long while when I bring my laptop out of sleep, the wifi
  fails to connect.  I don't see any obvious issues except that the
  kernel log shows that the wifi link is not ready.

  When I removed and reinserted iwlwifi, the network came up as
  expected.
