I actually tried to install wpa roaming following the howto in the sidux manual here :
http://manual.sidux.com/de/internet-con ... gui-de.htm
But the final result after writing "/usr/sbin/wpa_gui" in a console was like this:
Quote:
[/Failed to open control connection to wpa_supplicant.
PING failed - trying to reconnect
PING failed - trying to reconnect
PING failed - trying to reconnect

my /etc/network/interfaces
Quote:
# The loopback network interface
auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet dhcp
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supllicant.conf
# id_str="home"
iface home inet static
address 192.168.x.x
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.x.x
my /etc/wpa_supplicant/supplicant.conf
Quote:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

scan_ssid=1
psk="Mykey"
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
auth_alg=OPEN
priority=1000
id_str="home"
}
naturally i substituted the "x",the "SSID and the "Mykey" to the right ones.
But I really don't know why it doesn't work ?
additionally here the output of iwconfig
Quote:

Are there mistakes in my posted files ? or an has anybody an idea what's wrong ?

skyshow,
I have never tried a setup without DHCP, so I can only guess by what I see. Before the last bracket "}" you have a blank line. There should not be a blank line. No idea if that has any effect, but it is the only mistake I see in your wpa_supplicant.conf, so it might be the cause (supposing all your private data and the network parameters are correctly set).

group=TKIP
auth_alg=OPEN
priority=1000
id_str="home"
}
Correctly it should be then:
Code:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="MySSID"
scan_ssid=1
psk="Mykey"
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
auth_alg=OPEN
priority=1000
id_str="home"
}
Priority 1000 should work but I was hinted by the manual crew that it goes up to 1000, I personally use priority=15 as highest. But I don't think that's the cause.

You have your WPA key in "", so it is written in ASCII. If you use the HexCode phrase, you do not need "". I have never tried my ASCII key, only HexCode passphrases, so I cannot comment on using them.
As I said, only the blank line seems to be a mistake at first sight. Delete it and restart your network (or reboot). See how it works then.

I think I got it!
You have a terrible typo in your /etc/network/interfaces!
Code:
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supllicant.conf
It is SUPPLICANT and not SUPLLICANT!
So the line must read:
Code:
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

Well done, hubi!
That's why we probably should teach and encourage people even more to use copy & paste - instead of typing.
Greetings,

@hubi
you are an exact observer, thanks a lot, the typo was the mistake and additionally I deleted the blank line. I searched for hours.
btw, for the tip with the Hex code, how can I switch my ASCII -passphrase to Hex code.
@slam
You are absolutly right, but believe me for a beginner like me, it is quite good to make mistakes, because in this case to have to try out why the mistake come up and then you will probably understand how the system tricks !The only needed things are time and nerves.
But thanks a lot for your support
best regards

skyshow,
great 
Just for the record if someone pops in how to create a HEX passphrase (I just wanted to post it). As user (the real ssid and passphrase without brackets):
Code:
wpa_passphrase <ssid> <passphrase>

thanks hubi for your tutorial on wpa-roaming - inspired by this thread I tries it as well and after some attempts it worked:
etc/network/interfaces:
# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback
allow-hotplug ath0
iface ath0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
and:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="RedStar"
key_mgmt=NONE
wep_key0="xxx"
priority=10
id_str="home"
}
wpa-gui writes the configuration into your wpa_supplicant.conf when it is successfully startet. Reboot is important after you have configured your etc/network/interfaces and your wpa_supplicant.conf
And yes WEP ist not secure.
