Prism54

This article describes how you use the prism54 kernel module to get WLAN cards working.

Prerequesites

You have your WLAN card built into your computer and you need to use the prism54 driver with it:

kolossus:~ # hwinfo --wlan
20: PCI 202.0: 0282 WLAN controller
 ...
 Driver: "prism54"
 Driver Modules: "prism54"
   Driver Activation Cmd: "modprobe prism54"
...

How to use it

Load the driver:

modprobe prism54

I assume your WLAN device is eth1. Check that it works correctly by doing a

iwlist eth1 scanning

If it does not work correctly and you see the following error message in your /var/log/messages:

firmware.sh: cannot find firmware file

Then get the firmware file from the internet (http://www.google.com) and proceed according to the README file. In rare cases you will have to analyze firmware.sh where it searches for the file. To find firmware.sh, use

find -iname "firmware.sh"
