wifi stops working after xenial upgrade - HP Pavilion 13-b208tu w/ Broadcom BCM43142

[Stuart Bishop]

wifi no longer works on this laptop after upgrading to Xenial. I don't see any error messages. The wifi device is no longer listed in the network manager applet or by ifconfig.

Per Bug #1434136, this laptop is not using the latest bios availble for download, as it has never worked with Linux.

Stuart Bishop, thank you for reporting this and helping make Ubuntu better.

To advise, the bcmwl proprietary driver is not provided by the open source linux package.

Despite this, the latest driver for your hardware is available as per https://launchpad.net/ubuntu/+source/broadcom-sta in http://cdimage.ubuntu.com/daily-live/current/ . Hence, could you please test this, and advise to the results?

[Stuart Bishop (stub)]

The situation is unchanged with 6.30.223.271-2 from https://launchpad.net/ubuntu/+source/broadcom-sta

No wifi interface is listed by ifconfig or in network manager

Stuart Bishop, could you please advise to https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1602743/comments/3 precisely (not perform some other test that wasn't asked for)?
