Public bug reported: 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: *** 4.10.0.33.35 500 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu xenial-security/main amd64 Packages 100 /var/lib/dpkg/status 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.
