You have been subscribed to a public bug:
Release: Ubuntu 13.10
Installation Media: Desktop CD image from a USB stick with pendrivelinux
Hardware: Dell Inspiron 3721 with a Broadcom BCM43142A0 WLAN device.
[EXPECTED]
I would have expected that the live system and the installed system both have
automatic network connectivity via WLAN.
[ACTUAL]
1st problem: The live system didn't have WLAN network connectivity.
I was able to activate it simply by installing "bcmwl-kernel-source"
(after a lot of try and error):
sudo apt-get install bcmwl-kernel-source
(2nd problem: This is rather counter-intuitive. Why do I have to install
sources when I need a driver binary?)
3rd problem: When I booted into the installed system, network was down
again.
Here the fix was more complicated, surely too complicated for a non-
technical person:
[MY APPROACH]
sudo dpkg -i /media/hok/UUI/pool/main/d/dkms/dkms_2.2.0.3-1.1ubuntu4_all.deb
sudo dpkg -i /media/hok/UUI/pool/restricted/b/bcmwl/bcmwl-kernel-
source_6.30.223.141+bdcom-0ubuntu1_amd64.deb
[Proposed solution]
These problems would be solved if the Ubuntu installer installed the driver by
default, or after detecting an appropriate device.
