|
Hi Guys,
my notebook have a integrated WLAN card, an Intel PRO/Wireless 3945ABG (ipw3945). I try to connect to my WLAN router with WPA Supplicant. While connecting the WEP-Key will be removed (or is not used?), so the login failed.
Here are all my installed packages, configuration and result:

maybe im confused... why would you use wpa_supplicant to connent to a WEP secured wireless network? as far as i know wpa_supplicant only works with WPA secured access points. all you should need is the module for the card itself and wireless_tools.
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=4&chap=4#doc_chap3
also, if you have control over the access point i would change it over to wpa, as wep is incredibly easy to compromise.

Hi Joseph,
thanks for your answer. I would use WPA because networks (out of my home) requires WPA authentication. The configuration of my home network is only the beginning. 
The wireless tools aren't running, too:
| /etc/conf.d/net: | modules=( "iwconfig" )
key_wilster="[1] s:abcdefghijklm key [1] enc open"
preferred_aps=( "wilster" )
config_wilster=( "dhcp" ) |
| connection process: | * Starting eth2
* Configuring wireless network for eth2
* WEP key is not set for "<hidden>" - not connecting
* Couldn't associate with any access points on eth2
* Failed to configure wireless for eth2 [ !! ]
|
iwconfig via bash is running without problems:
| iwconfig: | localhost dennis # iwconfig eth2 essid wilster
localhost dennis # iwconfig eth2 key s:abcdefghijklm
localhost dennis # dhcpcd eth2 |
| result: | localhost dennis # iwconfig eth2
eth2 IEEE 802.11g ESSID:"wilster"
Mode:Managed Frequency:2.437 GHz Access Point: 00:13:49:4B:54:72
Bit Rate:54 Mb/s Tx-Power:15 dBm
Retry limit:15 RTS thr:off Fragment thr:off
Encryption key:XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XX Security mode:open
Power Management:off
Link Quality=94/100 Signal level=-35 dBm Noise level=-36 dBm

Umm, did you just modify that key so you did not have to announce it publicly to us or something, because "abcdefghijklm" is not a valid key - altough some basestations may be providing some sort of passphrase => key algorithm. Wpa_supplicant expects just valid hex..
Anyway, I would try to use wpa_gui to configure the settings - then you at least cannot make any typos 
I have used wpa_supplicant to connect to lots of different networks, WPA, 802.11i, WEP, unencrypted, and it works ok. Compared to my config, I don't have the quotes around wep_key0 and I don't have wep_tx_keyidx at all, but not sure if it makes any difference.
Oh, and do you need to use auth_alg=SHARED in your network? Some WEP networks are configured for shared auth instead of open.. |
