Title:
  Wifi becomes unstable upgrading from ubuntu 12.04 to ubuntu 14.04

Status in network-manager package in Ubuntu:
  New

Bug description:
  wifi becomes unstable upgrading from ubuntu 12.04 to ubuntu 14.04 for many users using intel wifi card (as described in thid thread:  http://forum.ubuntu-it.org/viewtopic.php?p=4587552), maybe a driver/kernel issue.
  about every half an hour the connection is lost and I have to reset both pc and router.

  slved via:
  sudo modprobe -rv iwl3945
  sudo modprobe -v iwl3945 swcrypto=1
  cat /etc/hosts
  sudo rmmod iwl3945
  sudo modprobe iwl3945

  Intel signaled a previous problem of compatibility between driver and
  some kernels.

  I updated recently from ubuntu 12.04 to xubuntu 14.04.  the problem
  didn't existed when I updated via 'update-manager -d', but appeared
  when I reinstalled new xubuntu from live dvd.
