[Ndiswrapper-general] Re: iwconfig command sequence + centrino

[<ndi...@xa...>]

To clarify, this issue affects me using 0.5 and 0.5-CVS (2004-03-15).

Yes, specifying all the options with a single command works fine for me.

I have wlan0 set up as a modprobe alias.

I've copied in some debug output below which may help. 

In the case where I issue the iwconfig commands in the wrong order
(i.e. where I try to set the WEP key before the ESSID), followed by dhclient
to set up my IP settings, this is the output I get:

If I issue the commands in the correct order, traffic flows between my box and the AP, and dmesg output is rather different, containing lots of lines like this
