Broadcom BCM43142 802.11b/g/n Wireless on Slackware 14.1


Hello!

I tried to get Broadcom BCM43142 Wireless card working on Slackware 14.1 with kernel 4.1.5.

I followed these instructions:
http://www.linuxquestions.org/questi...5/#post5067674

At first, several errors occurred which I managed to fix. I finally successfully installed the broadcom-sta package.

But when I try to modprobe wl module, I get the following message:
Code:
modprobe: ERROR: could not insert 'wl': Unknown symbol in module, or unknown parameter (see dmesg)
dmesg:
Code:
[28095.007548] wl: module license 'unspecified' taints kernel.
[28095.007552] Disabling lock debugging due to kernel taint
[28095.008837] wl: Unknown symbol lib80211_get_crypto_ops (err 0)
So, can anyone of you help me get this fixed?

Thanks in advance.

That thread contains several different options and hints and instructions.

Could you list what precisely you did?

This is a shot in the dark, but did you install bw-fwcutter?

Here's what I did:
1. I downloaded broadcom-sta: http://slackbuilds.org/repository/14...h=broadcom-sta
2. Download this tarball: http://www.broadcom.com/docs/linux_s...223_141.tar.gz
3. Replaced bc_wl_abiupdate patch with the one available here: https://bugs.gentoo.org/show_bug.cgi?id=477372
4. Replaced broadcom-sta.Slackbuild with the one available here: http://www.linuxquestions.org/questi...0/#post5032762
5. Fixed several incompatibilities with Linux 4.1.5 by hand. (Some function signatures have changed since Linux 3.10.x.)

And no, I have not installed bw-fwcutter.

The problem seems to be related to kernel configuration. I tried 3.10.87, 3.12.x, 3.14.x and 3.18.x kernels with the same configuration and it did not work on any of these. But it worked on stock 3.10.17 kernel.

It's been a long time and the details are hazy, but I think you need bw-fwcutter to cut the firmware out of the binary blob and make it available to the kernel.

Here's my Broadcom and Slackware thread in case it helps: http://www.linuxquestions.org/questi...urrent-926077/

Once I got it working, it worked continuously through all the updates on --Current until the wireless card itself died about six months ago.

Good luck and keep us posted.
