I've now tried both of the following sequences: ifconfig wlan0 up iwconfig wlan0 key myhexkey
and ifconfig wlan0 down iwconfig wlan0 key myhexkey Both produce the same error message as before. I also tried unloading and reloading the iwlcore and iwlagn modules before each sequence of commands. This also made no difference. ----- Original Message ----- From: "Guus Sliepen" <[email protected]> To: "S Hwang" <[email protected]>, [email protected] Sent: Friday, July 24, 2009 7:24:22 AM GMT -05:00 US/Canada Eastern Subject: Re: Bug#538217: wireless-tools: iwconfig can't set key but wpa_supplicant can On Fri, Jul 24, 2009 at 02:38:32AM -0400, S Hwang wrote: > I'm setting up a new install on a Medion Akoya P6611.

If you already tried it with the interface up, try it with the interface down before running the command. > Perhaps this is a driver problem, and not specifically something with > iwconfig, but I don't know how to tell beyond what I've already tried. I suspect it is a driver problem. -- Met vriendelijke groet / with kind regards, Guus Sliepen <[email protected]>
