wireless problems Unable to set key / freq Invalid argument??

trying to get wireless up on my dell mini 9

i am able to scan ap's but whenever i try to connect i get the following

sudo iwconfig eth0 essid Myessid key 101993D8SA77ADFetcetc
Error for wireless request "Set Encode" (8B2A) :
        SET failed on device eth0 ; invalid argument.

any ideas on this?

thanks!

EDIT: some info

my wireless 128 bit 64 hex digits
broadcasting on channel 6 (2.437G freq)

rc.conf

eth0 = "dhcp"
eth1 = "dhcp"
wlan_wlan0="etho essid myessid key MYKEY
INTERFACES=(eth1 wlan_wlan0)

Re: wireless problems Unable to set key / freq Invalid argument??

Hi,

I had the same problem with my tx2z and broadcom-wl. After reinstalling the wl and trying to enter the key as a string "key s:XXXXXXXXXX" I had a look at the key setup using iwlist:

[alpha@myhost ~]$ sudo iwlist eth0 key 
eth0      4 key sizes : 40, 104, 256, 128bits
          4 keys available :
        [1]: off
        [2]: off
        [3]: off
        [4]: off
          Current Transmit Key: [1]

from there I decided to manually state the key rather than allowing implicit decleration. Hence writing:

[alpha@myhost ~]$ sudo iwconfig eth0 essid BTHomeHub-XXXX key [1] XXXXXXXXXX

rather than the error producing:

[alpha@myhost ~]$ sudo iwconfig eth0 essid BTHomeHub-XXXX key XXXXXXXXXX

This produced no errors and allowed the connection. Hope this helps, and sorry for lack of technical understanding (it were a bit of trial and error and have only recently started with arch).

Also, if it helps, my rc.conf section is as follows:

INTERFACES=(eth0)

and my ifconfig and iwconfig are:

[alpha@myhost ~]$ ifconfig
