opensuse 13.1 wifi with broadcom b43 device i wan't to backlist

I have a laptop with opensuse 13.1 64 bit kde
wifi below

I have setup but have problems on heavy load.If i set to just 54Mb on router seem to be ok but limited on speed

modprobe shows

modprobe -l | grep b43kernel/drivers/net/wireless/b43/b43.ko
So researching it seem i should have only one.

IF I modprobe -r b43legacy
then check with modprobe -l | grep b43
its still loaded

so i added
blacklist b43legacy to /etc/modprobe.d/blacklist.conf at the bottom
install b43legacy /bin/false reserched that this would force not to load even if called
added file in /etc/modprobe.d with blacklist b43legacy
though one of above methods would stop install

didn’t still loaded after reboot

1)am i correct that only one of the 2 modules should load
2)have i used correct method to stop module from loading[/size]

sorry just found out that
brcmsmac module is also loaded

After much playing around with the three drivers
b43 won’t run comes up with error
broadcoms sta wl driver won’t compile as i think it only supports up to 3.5 kernel at the moment
brcmsmac driver works .does not work on mine if wifi set to n drops off
if set to g kind of works slow .Did not wan’t to set wifi to g just for laptop.

I had a atheros ar5b95 mini pci-e kicking around so decided give up on broadcom and stripped laptop to bits fitted atheros
works spot on in linux and windows.maxing out connection
so consider this close.
