For now I have found this howto: fedora18: Wireless Broadcom Corporation BCM43142 802.11b/g/n
---------------------------------------------------------------------
I adapted this procedure for openSuse 12.3:
---------------------------------------------------------------------
1. Install needed packages:
zypper install dpkg make gcc binutils kernel-source
2. Create bash script (see below) and run it:
#!/bin/bash
#

set -x
dtmp=$(mktemp -d)

wget -c http://jas.gemnetworks.com/debian/po...19-1_amd64.deb

dpkg-deb -x wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb $dtmp

cd $dtmp/usr/src/wireless-bcm43142-6.20.55.19/

make API=WEXT

mkdir -p /lib/modules/$(uname -r)/extra/wl
rm -f /lib/modules/$(uname -r)/extra/wl/wl.ko
cp ./wl.ko /lib/modules/$(uname -r)/extra/wl/.

depmod -a

modprobe -r wl
sleep 8
ip a

modprobe wl
sleep 8
ip a

cd
rm -rf $dtmp
3. Check that your wireless interface is working:
# iwconfig
p2p1 no wireless extensions.

lo no wireless extensions.

Now my wireless is working fine!
