Subject: Fwd: Issues with Intel Centrino advanced-N 6235

Hi,

I recently bought A Dell XPS 13 Developer edition (Ubuntu Based Laptop)

I had major problem with the wireless. After a while, the wireless
interface randomly drops and only a reboot will bring back the
wireless interface.

This issue was pretty bad using the default installation provided by
Dell (12.04). I then upgrade to 12.10 to see the same sort of issue,
currently I am running Ubuntu 13.04 running KDE and kernel 3.10

I currently have a usb Gigabit Ethernet Adaptor attached, hence why
the the Ethernet interface (the laptop is an ultrabook with no
ethernet ports as standard)

I have downloaded the latest intel firmware from
http://wireless.kernel.org/en/users/Drivers/iwlwifi hoping it could be
firmware related or atleast different than whats provided with Ubuntu
and unfortunately no difference:

I have tried enabling the following module parameters:

[email protected]:~# cat /etc/modprobe.d/iwlwifi.conf |grep option
#options iwlwifi 11n_disable=1 swcrypto=2 power_save=0

I had the exact same issue. Suddenly the interface just drops. Looking
in dmesg I get the following output:

At the end you will notice Failed to load firmware chunk. I do an
rmmod iwldvm and iwlwifi and the modules are successfully removed and
I can then reinsert both modules but the wireless interface completely
disappears and dmesg says that it could not load the firmware.

[email protected]:/var/log# dmesg |grep -i firmware
[ 0.143458] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored
[ 44.270456] iwlwifi 0000:01:00.0: loaded firmware version
18.168.6.1 op_mode iwldvm
[26486.356816] iwlwifi 0000:01:00.0: Failed to load firmware chunk!

Ive also noticed the onboard touchpad acts extremely weird and I end
up being forced to do a reboot (if I have external / mice keyboard and
usb ethernet adaptor everything is fine it runs normally -- when the
laptop has nothing plugged in and the wireless dies the laptop begins
to stall and needs to be rebooted - not sure why this other than the
kernel module crashing. )

The wireless usually works fine for at least a few hours, before this
happens. I can suspend and resume just fine everything works, but left
on and using wireless for a few hours it suddenly does this, in fact
the time it takes is completely random as well.

I am not sure at this point if it is a faulty wireless card or driver
/ firmware related.

The dell laptop itself has had the latest firmware installed (A08)
downloaded and installed from the dell support site.

Any help you could provide I would greatly appreciate, I can provide
you with any further information you require.

Thank you in advance,

Kind Regards,
