Ubuntu 11.10 Lenovo X201 intel Centrino N-6200 Wifi problem

[dvorim4]

Hello,
I'm a beginer with linux and I have a problem with my wifi card. I think system can find it but can't turn it on. I tried to find something on the internet but without success.

Thanks for any help.

Here are some results of commands.

Let's have a look at a few more items. Please open a terminal and run and post:

sudo iwlist wlan0 scan
dmesg | grep -e wlan -e iwlagn

The pipe symbol | is on the right side of my US keyboard on the same key with \. Thanks.

[dvorim4]

Thank you very much for your interest.

Here are the results
The result of second command is cutted when the log starts repeating but it is full in the atachement.

dvorakm@dvorakmntb:~$ sudo iwlist wlan0 scan

I wonder if we've seen this before...hmmm...YES!

Please see here: https://bbs.archlinux.org/viewtopic.php?id=125486 and here: http://bugzilla.intellinuxwireless.o...ug.cgi?id=2314

In this case, the person loaded an older version of the firmware (microcode) and says:

the wireless is ok with the older uCode

Let's see if we can try the same approach. Please go here: http://intellinuxwireless.org/?n=dow...&f=ucodes_6000

As you can see, the latest version is 9.221.4.1. That's what you have and what was loaded according to your dmesg:

[ 15.432056] iwlagn 0000:02:00.0: loaded firmware version 9.221.4.1 build 25532

Please download the previous version 9.193.4.1 to your desktop. Right-click it and select Extract Here. Now open a terminal and we back up your current ucode:

sudo mv /lib/firmware/iwlwifi-6000-4.ucode /lib/firmware/iwlwifi-6000-4.ucode.bak

Now we copy the earlier ucode from your desktop to /lib/firmware:

sudo cp Desktop/iwlwifi-6000-ucode-9.193.4.1/iwlwifi-6000-4.ucode /lib/firmware

Now reboot and let us see again:

dmesg | grep -e wlan -e iwlagn

I looked at the links you posted and saw that they had similar problem and intel card too.
So I tried both of older firmware from intel site but that bug is still there (and the truth is out there )
Do you have any other idea?
Now I have 9.176.4.1 firmware in my laptop.

In attached files is log of dmesg | grep -e wlan -e iwlagn for each firmware
