I see that first 3 "wpa_cli status" wlan0 was connected,
at the fifth "wpa_cli status" in line 41, something has disturbed the connection
and failed since.
Now question is what was going on there behind.
You say you did not do any action other than repeatedly calling "wpa_cli status"?
seems that multiple process is trying to connect the same "wlan0" at the same time,
and 1st agent (??) succeeded, and 2nd agent failed. The 2nd, that failed is something
related to wpa_supplicant. I can't say anything exact, but would try to disable the
wpa_suplicant once, and trying to connect without it. |

Exactly, the only thing I was doing was launching those commands inside the konsole.

How do I disable wpa_supplicant? Can I try then to connect with wicd? |

for example, I can connect with "# ifup wlan0 " with this configuration
in /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
#allow-hotplug eth0
#iface eth0 inet dhcp
auto wlan0
iface wlan0 inet dhcp
wpa-psk ournetworkname
wpa-ssid justapassword
and I suppose this does not use wpasupplicant.
To be sure, I tried disconnecting and connecting again, after removing wpasupplicant
package. (you don't need to remove it. It was just with purpose to prove.)
# apt-get remove wpasupplicant #-- this removed ceni together
# apt-get install ceni wpasupplicant -d #-- download the .deb file, even when net will be down,
# ifdown wlan0
# ifup wplan0
and voila, I was connected again, without wpasupplicant
then
# apt-get install ceni wpasupplicant #-- to have ceni again on my system
(I repeat, you don't need to do experiment of removing wpasupplicant package.
just disable the config to use it in /etc/network/interfaces.) |

Usually in /etc/network/interfaces. But I only know how to activate network-manager (a shaky solution) and I am not firm in using wicd (I use wpasupplicant for years now on a all my notebooks).
But our friends who use wicd should be able to help!

| If you want to connect to WPA1/ WPA2 networks, wpasupplicant is always involved - either rather directly through ifupdown or indirectly as backend invoked by network-manager or wicd through dbus. For aptosid, we don't really recommend network-manager (or wicd), as both have their own quirks and issues and often hide the real problem. The Debian packaging for wpasupplicant offers a quite decent roaming mode (configured through ifupdown), which "always" works, regardless of dbus or X11. |

Ok, I followed your advice with no luck  Same thing happens. Connects, disconnects.
I also have already done a clean install of the system with dist-upgrade and it's the same.
I've read somewhere that the rt2x00 firmware is already in the kernel (added recently), yet the fw-detect tells me to install firmware-ralink. Might it be that there's a collision? Because after the installation of firmware-ralink I run "modprobe -r rt2800lib" which returns a fatal error that it is already in use !? |

You might have a conflict.
To see which firmware are being loaded by the kernel. In a terminal:
Code:
dmesg |grep firmware
To see which modules are being loaded:
Code:
lsmod |grep 80211

I can't say I understand these outputs
Does it look alright?
dmesg | grep firmware
Code:
[ 6.839055] elantech: assuming hardware version 2, firmware version 2.0.48
lsmod | grep 80211
Code:
mac80211 174933 3 rt2800lib,rt2x00pci,rt2x00lib
cfg80211 123989 2 rt2x00lib,mac80211
rfkill 12348 4 eeepc_laptop,cfg80211,bluetooth
lsmod | grep rt2
Code:

Seems that the problem was hidden in the kernel since 2.6.33 or so.
I've found the solution here - http://www.ctbarker.info/2010/05/ubuntu-1004-wireless-chipsets-and-wpa.html
The important is to not install the firmware-ralink. The firmware should be downloaded from www.ralinktech.com and placed in /lib/firmware.
So the wifi works ok. Instead wlan0 it is named ra0, but that's ok.
The only thing that's still buggy is the led that doesn't reflect the state of wifi. However the function key does work. |
