Title:
  8086:4237 NM disconnects from 802.1x network shortly after
  authenticating -- Intel PRO/Wireless 5100 iwlwifi

Status in “linux” package in Ubuntu:
  Incomplete
Status in “network-manager” package in Ubuntu:
  Confirmed
Status in “wpasupplicant” package in Ubuntu:
  Confirmed

Bug description:
  Very similar to bug 548992, following post at bottom requesting
  separate submissions for new occurances.

  "iwconfig wlan0 power off" fails to fix the problem.

  Similar problem here:
  http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2305

  In that post, suggested that the problem lies in
  supplicant/dhclient/dhcpcd

  Please let me know if any other information or logs are required. I
  have a pretty substantial supplicant / nm syslog tail attached while I
  go through the whole shebang (with funny notes!).

  Cheers all.
