 Posted: Tue Oct 07, 2008 1:39 pm Post subject: iwl3945 + wpa_supplicant + hardware switch |
 |
|
Hi everyone!
I've got a problem with wpa_supplicant that bugs me for some time now. If I have the hardware switch turned on before I boot gentoo everything works fine, but when I switch it of and on again or switch it on after gentoo has booted wpa_supplicant can't find any network (wpa_cli status says scanning forever).
To get it back working again I have to switch it off and kill wpa_supplicant, then switch it on again and run /etc/init.d/net.eth1 restart.
I have hotplug, coldplug enabled in /etc/conf.d/rc, ifplugd installed and I use the iwl3945 kernel driver on gentoo-2.6.25-r8.
/etc/conf.d/net
| Code: |
dns_domain="home"
config_eth0=( "dhcp" )
dhcpcd_eth0="-t 3"
config_eth1=( "dhcp" )
modules_eth1=( "wpa_supplicant" )
wpa_supplicant_eth1="-w -Dwext"
|
wpa_supplicant.conf
| Code: |
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=0
fast_reauth=1
eapol_version=1
ap_scan=1
network={
ssid="home"
bssid=00:0F:EA:84:56:C8
scan_ssid=1
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk=XXXX
priority=10
}
|
So, does anyone have any idea what I did wrong? |

Hi, first I'm stone to see that you don't use wlan0 ?
Can you post this :
| Code: |
# lspci
# ifconfig -a
# iwconfig
# rmmod iwl3945
# modprobe iwl3945
# dmesg | tail
|

Do you think the devicename brakes any scripts? I changed that a while ago when I switched from ipw3945 to iwl3945.

I believe proper support for both the RF kill switch and the LED is available in 2.6.26, I believe 2.6.25 is limited.
I tried testing version of 2.6.26-r1 and it does work, however there is some other strangeness going that made we want to stay with the current most recent stable versions of Gentoo Sources rather than the testing version. So, for now I remain on 2.6.25-r7
Cheers,

I have a similar problem. If I switch it off while it's working and switch it back on again, it works. However, if I boot up with he switch off, I have to restart the network. As a solution I have a little script that does a few useful commands through sudo.
I use linux-2.6.27-rc6, and I had the same thing with 2.6.26.

Hi, we gonna need to clean up your previous IPW3945 installation.
First, can you post this :
If you still have something, then emerge -C [package_name]
Also, I'm sure that Udev is crazy :
| Code: |
# cat /etc/udev/rules.d/70-persistent-net.rules
|
If you have a line like this :
| Code: |
# PCI device 0x8086:0x4227 (ipw3945)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:1b:77:4f:4b:1a", NAME="eth1"
|
Comment it and also, you need to reboot your box and recreate this :
| Code: |
# cd /etc/init.d
# ln -sfn net.lo net.wlan0
|
Now, do you still have the problem ? |

Jupp, it's still there.
I had nothing left installed from the old driver.
equery list ipw

I changed the devicename to wlan0, but that didn't do the the trick.

Hi,
It's nice that you got your interface names sorted out, but I don't believe that's your problem. It's the kernel!
As in my previous post, you need to use 2.6.26 for proper RF kill switch operation. Unless someone knows otherwise, your requirements won't be met until you start using 2.6.26 instead of 2.6.25.
Cheers,

In fact, you need to use the kernel 2.6.26, but the Iwl3945 really need to communicate with the wlan0 interface.
So, I think that this is part of your problem. |

You will need this inside your kernel :
| Code: |
(M) RF switch subsystem support
(M) Input layer to RF switch connector
(*) Wireless LAN
(*) Wireless LAN (IEEE 802.11)
(M) Intel Wireless Wifi Core
(*) IWLWIFI RF kill support
(M) Intel PRO/Wireless 3945ABG/BG Network Connection
(*) Enable Spectrum Measurement in iwl3945 drivers
(*) Enable LEDS features in iwl3945 driver
(*) Enable full debugging output in iwl3945 driver
(*) LED Class Support
(*) LED Trigger support
(*) Cryptographic algorithm manager
(M) SHA1 digest algorithm
(M) SHA256 digest algorithm
(M) ECB support
(M) CBC support
(M) PCBC support
(*) AES cipher algorithms
(*) AES cipher algorithms (i586)
(*) ARC4 cipher algorithm
(*) Michael MIC keyed digest algorithm
|
For the rest, just post if you need help with the kernel 2.6.26. |

Thanks! I tried kernel 2.6.26 but without success.
I will try it again when gentoo-sources-2.6.26 go stable.
Thanks anyway! |

Try this:
| Code: | | cat /sys/class/net/wlan0/device/enable |
if it's 0
then try this:
| Code: | | echo 1 >> /sys/class/net/wlan0/device/enable |
this should turn on the hardware.
the path is for my hardware, and you may need to tweak it a bit to get it to work |
