With a completely updated installation of 16.04.0 LTS, using b43 wifi,
the wifi indicator light remains solid, and does not flash to indicate
activity. This mirrors the Microsoft Windows behavior for wifi
indicator lights.
On the same hardware, with an updated installation of 16.04.3 LTS or
16.04.0 with the HWE kernel, the wifi indicator light remains off and
flashes to indicate activity. This can lead the user to believe that
wifi is not functioning at all.
Description: Ubuntu 16.04.3 LTS
Release: 16.04
linux-generic-hwe-16.04:
Installed: 4.10.0.33.35
Candidate: 4.10.0.33.35
Version table:
*** 4.10.0.33.35 500

Expected behavior: With the wifi hardware switch in the 'On' position, the wifi
indicator light should remain lit and not flash. The indicator should only be
off with the hardware switch in the 'Off' position, or in the event there is a
malfunction. This is the behavior with 16.04.0 LTS.
What happened: With the wifi hardware switch in the 'On' position, the
wifi indicator light remains off, and flashes only during wifi activity.
This regression is seen both with an installation of the HWE stack as
described at https://wiki.ubuntu.com/Kernel/LTSEnablementStack or with a
fresh installation of the current 16.04.3 LTS.
