Subject: No WLAN on DELL XPS L702x with Ubuntu 12.04LTS (64Bit)

Hello,

on an DELL XPS L702x under Ubuntu 12.04LTS (64Bit) the WLAN is not working.
The network manager show the message
"device is no ready"

On an other DELL XPS L702x Notebook with the same "lspci -v" with only
one difference in graphic controller
< 01:00.0 VGA compatible controller: NVIDIA Corporation Device 0dd6 (rev ff)
---
> 01:00.0 VGA compatible controller: NVIDIA Corporation GF106 [GeForce
GT 555M] (rev ff)
works on the Notebook with "NVIDIA Corporation Device 0dd6" the WLAN well.

With a Live-DVD (64Bit) the same effect.
sudo dmidecode give no differences.
Kernel is 3.2.0-27-generic or older.

The effect is like the modul iwlwifi is not loaded (sudo rmmod iwlwifi),
although the module is loaded on both Notebooks.

Is the module dell_laptop buggy?

What can I do that the WLAN is working also on the second Notebook?

- Please provide a lspci -vn of the device not running, too.

- Did you try actual compat-wireless from
http://linuxwireless.org/download/compat-wireless-2.6/
Does it show the same behaviour?


Thanks,
kind regards,
Andreas

How long does the boot take? (From the time you press the power button
until you see the message in the logs).

Can you please add a file (let's say iwlwifi.conf) in
/etc/modprobe.conf with content:
options iwlwifi debug=0xffffffff

And send the output.

Is this a laptop from a big corporate?

Hi Emmanuel,

unfortunately, Christian doesn't know how to handle a mailing list.
That's why I'm forwarding his answers for the list and may be for you, too.

He wrote, too, that the installation of compat-wireless (unfortunately,
he didn't told me which version), didn't changed the situation.

I attached for him the output of
options iwlwifi debug=0xffffffff

The last part of it:

[ 675.594758] iwlwifi 0000:03:00.0: Failed to run INIT ucode: -5
[ 675.594863] iwlwifi 0000:03:00.0: Unable to initialize device.

I hope this debug output can help you to find the problem!
