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.
