Hi,

I managed to connect to the campus's AP (E-U), but i still have some problems associating, when i run wpa_supplicant with wpa_supplicant -D wext -i eth1 -c /etc/wpa_supplicant.conf, it takes a while bue the authentication is successful, however, after autenticating i have the following problems:

Code: Select all

ioctl[SIOCSIWENCODEEXT]: Invalid argument
EAPOL: Failed to set WEP key to the driver.

I'm running suspend2-sources 2.6.14, using the portage ipw driver, 1.0.8 and firmware 2.4

Do you have any ideas?

Thanks in advance.

Shouldn't the driver be "ipw" and not "wext"?

Actually, with the ipw driver I get ioctl errors, it seems that for kernels >=2.6.13 you have to use -D wext because of internal API changes.

bump.

I'm getting the exact same problem. And haven't found a workaround it.

Here's a bit more complete output from wpa_supplicant:

Using the kernel driver on 2.6.15-rc* solved it for me, I tried the one on 2.6.14 but i got the same result as before. On 2.6.15-rc1 though it's working perfectly.

Good luck.

I'm experiencing the exact same problem. Using kernel 2.6.15_rc5 does not solve the problem for me - I get the exact same message still.

Is this a regression between rc4 and rc5? Or is there a difference between ipw2100 and ipw2200 here? (I'm using the ipw2200 driver, on a freshly installed Gentoo installation stable x86).

Using wpa_supplicant 0.4.7 (unstable) or 0.3.9 did not make any difference either....

Anyone still have the same problem, or knows anything else I could try?

krani1 · Post by **krani1** » Tue Dec 20, 2005 4:44 pm

got the same problem here with

gentoo-sources-2.6.14
ipw2200-1.0.8-r1
wpa_supplicant-0.4.7

i will try to update my kernel and maybe use the kernel bultin drivers for my ipw2200

PT_LAmb · Post by **PT_LAmb** » Tue Dec 20, 2005 5:18 pm

Ok, I've solved my problem...

I uninstalled

net-wireless/ieee80211-1.1.6
net-wireless/ipw2200-1.0.8-r1

Installed

sys-kernel/vanilla-sources-2.6.15_rc4
net-wireless/ipw2200-firmware-2.4

compiled the kernel with the following options

Code: Select all

Networking  --->
     <M>   Generic IEEE 802.11 Networking Stack
          [ ]     Enable full debugging output
     <M>     IEEE 802.11 WEP encryption (802.1x)
Device Drivers  --->
     Network device support  --->
           Wireless LAN (non-hamradio)  --->
                 <M> Intel PRO/Wireless 2200BG and 2915ABG Network Connection

Inserted the modules to the auto load list (you might not need this)

Code: Select all

# echo ieee80211 >> /etc/modules.autoload.d/kernel-2.6
# echo ieee80211_crypt >> /etc/modules.autoload.d/kernel-2.6
# echo ieee80211_crypt_wep >> /etc/modules.autoload.d/kernel-2.6
# echo ipw2200 >> /etc/modules.autoload.d/kernel-2.6

Restart the system with the new kernel.

configured /etc/wpa_supplicant.conf

Code: Select all

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
ap_scan=1
fast_reauth=1

network={
       ssid="e-U"
       scan_ssid=1
       key_mgmt=IEEE8021X
       eap=PEAP
       identity="axxxxx@iscte.pt"
       password="xxxxxxxx"
}

added the following to /etc/conf.d/net

Code: Select all

modules=( "wpa_supplicant" )

wpa_supplicant_eth1="-Dwext"
wpa_timeout_eth1=60
config_eth1=( "dhcp" )
dhcpcd_eth1="-t 10"

Now, everytime I need to start the wireless connection, I type the following commands

Code: Select all

# iwconfig eth1 enc [1] 0
# iwconfig eth1 enc [2] 0
# iwconfig eth1 enc [3] 0
# iwconfig eth1 enc [4] 0
# iwconfig eth1 enc off
# iwconfig eth1 mode ad-hoc
# /etc/init.d/net.eth1 start

The first 6 commands solve a lot of connection problems that might stall the connection start. The last one starts the wireless connection.

I had to install a 2.6.15 version of linux kernel because the 2.6.14 seems to not like ipw2200.
I've also heard that 2.6.13 doesn't issue any problem, but haven't checked that out.

I hope this helps someone in the future.
