3.13.0-6-generic#23~precise2 on dell e6500:

wifi still works only when apparmor is de - activated (apparmor=0).
As mentioned above, the corresponding mainline kernel (3.13.1-031301-generic from v3.13.1 (trusty)) works including wifi.

Title:
  kernel 3.13.0-4.19~precise1-generic: no internet via ethernet or WiFi

Status in “linux” package in Ubuntu:
  Confirmed
Status in “linux” source package in Precise:
  Confirmed

Bug description:
  After booting no connection to the internet can be established, via
  cable or wifi. No such problem is found with 3.13.0-031300rc8-generic
  (mainline) nor with 3.11.0-16-generic (in both cases connection is
  established both via cable and wifi).

  WORKAROUND: WiFi works replacing "quiet splash" by "apparmor=0" in
  /etc/default/grub .
