I have a brand new Toshiba Satellite P855-S5200, and cannot get wifi working on it under OpenSuse 12.1 (now with a Tumbleweed kernel), but OpenSuse cannot drive the wifi.  This laptop has an Intel® Core™ i7-3610QM Processor, and Windows 7 drives the wifi flawlessly, claiming it is a Centrino-N 2200 device (if memory serves, I'll send a correction if this is wrong).  Neither Opensuse 12.1 nor the upgraded kernel worked, they gave the messages:

Since the chip may be newer than the kernel version, I checked windows which said it was a Centrino Wireless-N 2200 and looked at http://www.intellinuxwireless.org/, which says: Intel® Centrino® Wireless-N 2200 (3.2.0), so I tried the tumbleweed kernel, so currently:

However, in /var/log/messages I still get:

Is there a workaround or fix for this?

Reproducible: Always

Steps to Reproduce:
1.Boot Windows 7, watch the wifi work flawlessly
2.Boot Linux, observe that the OS disabling wifi
3.Try KDE network manager and see that it cannot find my wireless ethernet adapter.
Actual Results:  
No special setup is required.

Expected Results:  
Have linux find the wifi like it does for every other intel wifi I've used in the last 4-6 years.

Hello All:

I think I know how to fix this and what the problem is.

Would the maintainers please be so kind as ensure that the microcode is installed in /lib/firmware as per the hints at: http://mtekk.us/archives/guides/fixing-request-for-firmware-file-failed/

OpenSuse does use modules, however please note that there is now iwlwifi-2000-*.ucode module, where * wildcards the version number, in /lib/firmware.
Downloading and installing the iwlwifi-2000-*.ucode (in my case * = 6) from http://intellinuxwireless.org/?n=downloads into /lib/firmware fixed the problem with the tumbleweed kernel.  I have not reverted to Opensuse 12.1 yet, so that kernel remains untested, but the Tumbleweed kernel 3.4.30 appears to work.

Comment 2 Foolish Ewe 2012-07-05 01:53:13 UTC

I reverted to 12.1 and the iwlwifi-2000-6.ucode firmware fails with both the installed and updated versions of the kernel (in my case the desktop kernel).  Unfortunately I had no joy finding iwlwifi-2000-5.ucode (please note that I tried renaming the iwlwif-2000-6.ucode to iwlwifi-2000-5-ucode, but that did not work), so I'm stuck with tumbleweed. Now if I can only get sound working... but for that I'll open a different bug report.

Comment 3 Takashi Iwai 2012-07-06 06:57:15 UTC

You can find the updated firmware in Tumbleweed's kernel-firmware package (in noarch).  iwlwifi-2000-6.ucode is found there, too.

Reopen the bug if it still doesn't work.  Thanks.
