broadcom 802.11n network adapter driver windows 10 acer

In my case the solution 1 works with kernel 3.19.0-77-generic or 4.4.0-45-generic, but not with the later 4.4.0-53-generic. Thanks to user Pilot6 for pointing this out in the comments above.Ī new kernel does not cope well with the network and wi-fi settings. Secure boot in the boot set-up utility is enabled. In my experience the problem comes up for either of two reasons, or both: If you need to refer to verbose posts, please indicate which answer is applicable according to you and in which way it integrates the actions undertaken above. Please could you provide a list of simple steps to regain the possibility to enable the wifi from the menu bar? I am also aware of other posts that deal with earlier Ubuntu versions, but I would dearly avoid guesswork and find an answer that applies to 16.04 safely.

This is way too esoteric for me, but it may provide a clue to the expert. Interestingly, from this bounty-winning answer, I could see with lspci -nn | grep -i BCM that my network controller is a BCM43142 that might not be supported by the STA driver. It claims it will be asked later, although I did not see it being asked again.

Note that at sudo apt install bcmwl-kernel-source a dialogue window asks permission to disable Secure Boot by typing an ad hoc password. Sudo rfkill unblock all # for good measure Sudo apt install bcmwl-kernel-source # corresponds to my PCI id 14e4:4365 (rev 01) However, I have followed the uninstall/install sequence: sudo apt-get purge bcmwl-kernel-source I am almost-fully aware of this extensive post on Installing Broadcom Wireless Drivers, but installation is not the point. As a result I cannot activate and use the wi-fi. I cannot see any option to enable the wireless device from the applet main menu bar.
