bcmwl-kernel-source driver builds successfully but keeps asking for password but never connects

[Seb Bonnard]

Hi,

I'm using KUbuntu 14.04.4 with kernel 4.2.0-27-generic.

After installing bcmwl-kernel-source_6.30.223.248+bdcom-0ubuntu8_amd64.deb (which I have downloaded from http://packages.ubuntu.com/xenial/bcmwl-kernel-source) the following way :

$ sudo gdebi -n bcmwl-kernel-source_6.30.223.248+bdcom-0ubuntu8_amd64.deb :

The NetworkManager keeps on asking for the password of the wifi connection but fails to connect.

Can you help me ?

I'd be glad to add further information to this issue, just tell me how :-)

Seb.

As it is the NetworkManager keeps on asking for the password of the wifi connection and fails to connect, the problematic package could be the one that contains the NetworkManager :

plasma-nm or network-manager

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Same situation on my mid-2012 MacBook Pro; it never connects, even after the network information is entered using the dialog, or using ifconfig and ifup to activate.

One possibility is the change to cryptic device names since 15.04; perhaps sections of network-manager are still unaware of the changes.

Oh, I'd forgotten to mention that I'm using 16.04 Beta 2.
