After two days with the new module parameter, no wifi connection problems any longer. Marking the problem as solved.
Sure, will do this. But first, I'll wait a few more days and see whether the wifi issues really disappeared. Thanks again for your help.
Thanks for the hint. It seems to do the rick.
I guess that you're refering to a issue with iwlwifi in kernel 3.2 discussed here: https://bugzilla.redhat.com/show_bug.cgi?id=785239

Hello,
after dist-upgrade from 11.10 to 12.04 (64bit), my wifi connection got very unstable, and keeps bugging me. Until the dist-upgrade, everything worked fine. My hardware is a ThinkPad T420...
The changes to /etc/default/grub look correct. did you run 'sudo update-grub' afterwards? You can verify that the changes reached grub.conf by looking into /boot/grub/grub.conf. You should find the...
I discover issues with shutting down Ubuntu Oneiric on my T420 lately. Most of the times, the laptop is not halted and powered off, but instead reboots. Does anybody discover similar issues?

coretemp is compiled as module in default Ubuntu kernel. All you need to do is following the step-by-step tutorial I linked. See 'modinfo coretemp' for more information.
Yes, I upgraded from 11.04 to 11.10. Upgrading from one Ubuntu release to the next one is officially supported by Ubuntu and shouldn't cause major trouble.
I neither have issues with my trackpad, nor with my hotkeys. They all work as expected.
Here's another issue tracking post, which I try to keep up to date:

[/I]Great, thanks a lot for the hint. Indeed it works like a charm for me on T420.

You're sure that your _microphone_ mute key works? It really mutes the microphone? Or are you talking about your audio output mute key?
The path to temperature sensors changed with new Oneiric (11.10) kernel. See this post, especially the following subitem:

Now that I upgraded to Ubuntu 11.10 Oneiric Ocelot, I'll share my experiences again. First I have to say that all in all the upgrade went pretty smoothly. Below is a summary of the issues that one...
I'll give Ubuntu 11.10 a try as soon as it's released. For sure I'll share my experiences regarding issues with T420 in this forum.
yes speed of 2348 is not level 0. I guess that it was still spinning and level was just decreased. you should keep an eye on the level and speed of the fan. in case it changes frequently, and you see...
level 0 means that the fan is not running at all. are you sure that it's the fan that makes the noise?
Yes, that's correct. It's exactly the same as in my /etc/thinkfan.conf. Which Thinkpad do...
It seems like you added the line 'options thinkpad_acpi fan_control=1' to /etc/thinkfan.conf instead of /etc/modprobe.d/thinkfan.conf. Both files have different meanings. /etc/thinkfan.conf is the...

Thanks for your reply. Up to now, I didn't use this parameter. Now I added it to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub, ran update-grub and rebooted. Unfortunately it doesn't help anything....
