["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Vincenzo Costa, as per http://www.dell.com/support/home/us/en/04/product-support/product/latitude-e5530/drivers an update to your BIOS is available (A15). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?  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. As well, you don't
have to create a new bug report.

Once the BIOS is updated, then please mark this report Status New.

Thank you for your understanding.

** Description changed:

- I have a Dell latitude 5530 laptop with the Broadcom BCM43228 wireless card, and I currently run Kubuntu 14.04.1 LTS.
- It works ok with the 3.13.0-40 original linux kernel, but after installing the linux-generic-lts-utopic kernel (version 3.16-25) the wireless interface does not appear any more.
- 
- - The command:  dmesg  |grep 'BCM' doesn't give any output concerning
- the wireless interface wlan0 or the BCM43228
- 
- - The commands: iwconfig and ifconfig don't give output for wlan0
- 
- - The kubuntu applet for network connections does not allow to switch
- the wireless network on
- 
- It seems that the wireless network simply doesn't exist with the 3.16 kernel.
- Booting back with 3.13 kernel can fix the issue, so it's not a hardware problem.
-
