You need to install the packages
b43-firmware-4.178.10.4-noarch-64.1.txz and
b43_STA-5.100.82.38-i486-2.6.35.11.txz.
After installing those packages you have to blacklist the modules
b43 and
ssb. Since Zenwalk is based on Slackware I would assume that you have a file
blacklist.conf in
/etc/modprobe.d/. Edit this file as root and add the entries
Code:
blacklist b43
blacklist ssb
Save the file and restart the system. Now you should be able to use the wireless. I don't know if Zenwalk has a network manager already installed, I would recommend
wicd if you don't have one.
