Unable to use wirelles network in Kubuntu 12.10

[beardman]

I can not check the "Enable wireless" option. If I click this option it unselect itself. The option is available and not grayed out.

I've first encountered problem afrer upgrainug Kubuntu 12.04 to new kernel yesterday. I hoped that the problem will be solved after upgrading to latest Kubuntu version.

I believe that wireless card is not supported by kernel ie. I do not have the right drivers installed. Unfortunately I do not know which package to install or which configuration file I must change.

Data about my hardware.

x:/home/uros# lspci | grep -i net
02:00.0 Network controller: Intel Corporation Centrino Wireless-N 2230 (rev c4)

x:~$ iwconfig wlan0 
wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=16 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

Any help or pointers in right direction would be greatly appreciated.

Please check system for iwlwifi. For example:

lsmod | grep iwlwifi

If iwlwifi is installed, check /etc/modprobe.d/iwlwifi.conf file.
Your wifi card is ubuntu certified
There is some information about using Centrino Wireless-N 2230 in Ubuntu: http://ubuntuforums.org/showthread.php?t=2050475 Maybe it will be useful for you.

I seems iwlwifi is installed.

:~$ lsmod | grep iwlwifi
iwlwifi               386826  0 
mac80211              539908  1 iwlwifi
cfg80211              206566  2 iwlwifi,mac80211

The contents of /etc/modprobe.d/iwlwifi.conf

# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system.  When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac80211

Changing the parameters as suggested in linked thread did not help.

Some additional info. I've tried to run Kubuntu 12.10 from USB with same result. I've also tried Ubuntu 12.10 where I can connect to wireless network. I believe there is a bug in the way KDE handles wireless networks and not in the configuration, because iwlist finds networks and I am able to connect from command-line.

I've found workaround. You must click "Manage connections" and manually add wireless network.
