ipw2100 1.0.0

17 November 2004

The Intel ProWireless 2100 drivers have hit a 1.0 release, so I thought I'd cleanup the way I use them.

Initial versions of the driver didn't handle suspend, so I unloaded and reloaded them all the time. I also didn't want the radio powered all the time, so I blacklisted the module from hotplug as well, so I could load it by hand and configure the interface from a script.

I no longer need to reload the current version of the driver, so I'm letting hotplug load it. I still don't want the radio on by default, though, so I configured modprobe to load the ipw2100 module with the disable=1. I still use my scripts to bring the interface up and down in different environments, but the script uses the sys interface to enable and disable the radio, which is much faster than loading and unloading the module.

#enable
echo 0 > /sys/class/net/eth1/device/rf_kill
#disable
echo 1 > /sys/class/net/eth1/device/rf_kill

Next I'd like to figure out a way to maybe allow it to automatically switch the wireless on and off depending upon the presence of the wired link.
