Thinkpad X201 iwlwifi module stopped working in latest -21 kernel (OK in -19)

[professordes]

The wifi on my Thinkpad X201 has stopped working in Ubuntu 13.04 with the latest 3.8.0-21-generic kernel (it is fine in -19 and earlier).

Errors messages on loading module from /var/log/kern.log:

I think it has something to do with the latest kernel deciding the card has
"N" and then failing when it tries to enable it, leaving the wireless card
disabled.

Issue the command

sudo lshw -c network

and look for the wireless interface info. I bet that it will say "*-network
DISABLED".

This seems to work as a temp fix:

gksudo gedit /etc/modprobe.d/iwlwifi.conf

add the line

"options iwlwifi bt_coex_active=N 11n_disable=1"

at the beginning, before the remove iwlwifi line, save the file

and then

sudo reboot

That worked for me, with a gateway with a Intel 5100 wireless card.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[professordes (d-a-johnston-hw)]

Will check tomorrow when I am back at my office.

I am not sure if this was a one off. After a reboot the wireless came alive again with the -21 kernel on the X201.

I have seen no problems with a couple of Thinkpad X200S laptops after upgrade....

I think my suggestion was a red herring. Did some more testing this
afternoon. After removing the option line from/etc/modprobe.d/iwlwifi.conf
and rebooting again, wifi still works. So the "fix" seems to be a simple
reboot.

I suspect that something is messed up on first boot after updating the
kernel. Everything seems fine on subsequent reboots.

iwlwifi looks normal in dmesg, and the wifi interface comes up properly
now.

I had the same experience - after a reboot the wifi on the X201 came
alive....

Any updates on this? I met exact same problem. I am running ubuntu 14.04 LTS on lenovo(thinkpad) X201. The network card is really unstable and keep turning off randomly. I have to keep rebooting my laptop to fix this issue !!!!
