However, I have now noticed a change of behaviour. With 2.6.32.2 and earlier kernels the line for wlan0 appears in /proc/net/wireless before my configuration script is run by udev. With 2.6.33 the line doesn't appear until wpa_supplicant has been started by the script. I only look for the line as a way of making sure the modules have loaded. I can't remember now why I do that but I guess there must have been a time when udev started the script before the driver had initialised everything. It's not a big deal for me, because I can look in /proc/net/dev instead, but I thought a heads up on the behaviour change might be useful to others. I might no longer need the delay or maybe the script can simply sleep for a second or two - I'll experiment a bit. > You can try using iw to configure your card.

I'll have to experiment to find out what works. Thanks for the tip though.
