Hi Silas,
I am using 128Bit encryption and my AP is set to "Shared secret"
encryption. I am so far only using Key nr. 1.
With my old card and the prism driver it all worked with this configuration:
#=======WEP===========================================
# [Dis/En]able WEP. Settings only matter if PrivacyInvoked is true
lnxreq_hostWEPEncrypt=true # true|false
lnxreq_hostWEPDecrypt=true # true|false
dot11PrivacyInvoked=true # true|false
dot11WEPDefaultKeyID=0 # 0|1|2|3
dot11ExcludeUnencrypted=true # true|false, in AP this means WEP is
required.
PRIV_GENERATOR=/sbin/nwepgen # nwepgen, Neesus compatible
PRIV_KEY128=true # keylength to generate
PRIV_GENSTR="xxxxxxxxxxxx" <-- real string goes here of course
AuthType="sharedkey" # opensystem | sharedkey (requires WEP)
----
Of course I now this configuration cannot be used with the Atheros drivers.
I am using the ASCII WEP string with my old card, but I used as well the
Hex representation already with my XP drivers, so I know that the
hex codes I enter for the key are OK. (They are identical to what I've
set on the AP)
For setting the WEP keys with the Atheros driver I do the following:
iwconfig ath0 mode managed
iwconfig ath0 essid "ASGARD"
iwconfig ath0 mode managed
iwconfig ath0 rate auto
iwconfig ath0 channel 11
iwconfig ath0 key xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xx [1] <-- "xxxx" is
identical to what is set in the AP
iwconfig ath0 key [1] restricted
iwconfig ath0 key on
But this does not seem to have any effect, as the resulting "iwonfig
ath0" shows no key.
I repeat the procedure a couple of times until I get:
littleigloo:~ # iwconfig ath0
ath0 IEEE 802.11-DS ESSID:"ASGARD"
Mode:Managed Frequency:2.462GHz Access Point: 00:80:C8:12:4C:E0

Power Management:off
Link Quality:0/92 Signal level:24/154 Noise level:0/154
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

When I now try to send something on the network (e.g. get DHCP address
or ping) I get
"authentication failure (reason 13)". in /var/log/messages
littleigloo:~ # iwlist ath0 encryption
ath0 2 key sizes : 40, 104bits

littleigloo:~ # iwlist ath0 scanning
ath0 Scan completed :

Hope this makes sense to you!
