  8086:4232 Wireless not connecting on bootup in 12.04 (Intel Wifi Link

Status in The Linux Kernel:
Status in “linux” package in Ubuntu:

Bug description:
  Sometimes after booting Ubuntu, the wireless connection is not operational (e.g. ping in a console window shows nothing), although the network manager icons shows that connection is established.
  It is more likely (almost 100%) to happen if the machine hasn't been used for several days (which suggests to me it has something to do with obtaining dhcp leases). And even with the steps below, sometimes the wifi will work from the beginning as expected.

  However, steps that increase the chances to reproduce it are:
  * boot into ubuntu.
  * turn off wifi with the rfkill switch
  * sudo rm /var/lib/dhcp/dhclient*
  * reboot the system. At the GRUB screen, turn on the rfkill switch again, so that wifi is enabled at boot time
  * log into ubuntu. network manager will show a "wifi connected" icon (which is not the whole truth).
  * open up a console window and type "ping www.ubuntu.com". Nothing will be shown on the console

  Tested with linux-
  image-3.4.0-030400-generic_3.4.0-030400.201205210521_amd64.deb. For
  now, wifi seems to work with this kernel.

  WORKAROUND: * turn off rfkill switch. Wait until network manager popped up a message saying "wifi disconnected"
  * turn it on again

  WORKAROUND: * boot with wifi disabled by the rfkill switch
  * turn it on only *after* having logged in to your session
