I have a Lenovo X140e netbook with the Broadcom BCM43228 wifi controller. I cannot get it to work. I just installed LXLE-16.04.1 64bit just a couple of days ago.

With the default setup, as installed during installation, the wifi worked, but it would drop the connection randomly. First I tried installing the Broadcom proprietary driver using the Driver Manager. Once that was done I rebooted, wifi did not work at all. No wifi networks were displayed under the network manager icon. I then tried Fn+F5 to turn the rf on/off, no help.

I then removed the proprietary Broadcom driver using Driver Manager. Then I installed the "bcmwl-kernel-source" package using Synaptic, and UNinstalled the "b43-fwcutter" package. Still no joy after a reboot.

According to the info in Synaptic, the "bcmwl-kernel-source" package supports my netbook's hardware:

Info from Synaptic:
"This package contains Broadcom 802.11 Linux STA wireless driver
for use with Broadcom's BCM4311-, BCM4312-, BCM4313-, BCM4321-,
BCM4322-, BCM43224-, and BCM43225-, BCM43227- and BCM43228-based
hardware."

I also have UbuntuStudio installed on this netbook, the Broadcom proprietary driver works just fine there. I just can't get it to work here on LXLE. Maybe I need to blacklist something, but I don't know how or what to blacklist.

Here's my relevant system specs:

In Synaptic I compared the installed packages for 'broadcom', and 'firmware' between LXLE and UbStudio. In LXLE the exact same packages are installed as in UbStudio.


Any suggestions?

Thx,
