Title:
[Regression] [network UNCLAIMED] Wi-Fi stopped working in Xenial,
although it is working in Trusty
Status in bcmwl package in Ubuntu:
New
Bug description:
My laptop is Acer Aspire E5-551G-T0KC.
In Xenial, I have installed the propriety wireless driver from Additional
Drivers.
There are no Wi-Fi networks shown in the network indicator, as if the
wireless card does not exist.
This is a regression from Trusty.
Here are some terminal outputs that are specific to the wireless card:
