Andrei Borzenkov, as per http://www.dell.com/support/home/us/en/04
/product-support/product/latitude-e5450-laptop/drivers an update to your
computer's buggy and outdated BIOS is available (A10). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
address the issue?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Also, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status
Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.

** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete

Title:
  Wireless is disabled by rfkill after suspend with linux-image-generic-
  lts-wily

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I am running Ubunutu 14.04 on Dell Latitude E5450; Ubuntu came
  preinstalled on this notebook. After installing kernel linux-
  image-4.2.0-18-generic wireless is not available after resuming from
  suspend to RAM; in logs I see

  Nov 20 13:04:46 bor-Latitude-E5450 NetworkManager[1389]: <info> WiFi
  now disabled by radio killswitch

  This problem did not exist with original kernel linux-image-3.13.0-xx
  from 14.04 and updates.

  Probably related - original kernel is using iwlwifi driver

  Package: iwlwifi-3.16.2-dkms
  Status: install ok installed
  Priority: optional
  Section: misc
  Installed-Size: 65,6 MB
  Maintainer: Ubuntu Developers <ubuntu-devel-discuss@xxxxxxxxxxxxxxxx>
  Version: 1.0
  Depends: dkms (>= 1.95)
  Original-Maintainer: Dynamic Kernel Modules Support Team <pkg-dkms-maint@xxxxxxxxxxxxxxxxxxxxxxx>

  This driver does not compile for kernel 4.2.
