Having problems getting this to work. Note that the wireless card does not have firmware, so the firmware has to be loaded with hotplug.
Best site I have found is the following: http://home.columbus.rr.com/andrewbarr/dwl520e1.html
From this site I have been able to load the hotplug and even ping the router(once). I have not been able to get any of the boot configuration process to work however. In addition getting the iwconfig parameters correct is also a problem.
I can get the hotplug working 100% of the time via mannual commands, but the iwconfig is driving me crazy.
Any pointers on setting up hot plug and ifconfig at boot time?
thanks
