I have just install my wireless card driver ( bcm4312) on opensuse 11.1 (64bit)

my laptop is dell 1310

I use the most simple way

sudo zypper ar http://packman.mirrors.skynet.be/pub/packman/suse/11.1/ pack_man

sudo zypper install broadcom-wl

sudo reboot

the wireless card works.

install flash player x86_64 for firefox

sudo mkdir /usr/lib64/firefox/plugins

sudo cp libflashplayer.so /usr/lib64/firefox/plugins/
