Hello.
I have been running Ubuntu since 8.10 on my Thinkpad X200. Over the years,
my wifi has been problematic with linux, but the past year or so it's
generally been working well. However, lately I ran into a regression with
a stable rebuild of 3.2 (-35 in ubuntu-land).
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1096294
The information here is generally a bit low on detail because I have
little idea how to collect information suitable for meaningfull debugging.
Short: 3.2 gained a regression about 2 months ago. I usually solved
this by rebooting the AP or doing rmmod/modprobe iwlwifi, or rebooting
into 3.8.0 and then booting back into 3.2.0-34.
Then when I tried -39, my 5GHz wifi stopped working completely (would only
stay associated for a few seconds, then disconnect with local reason 3),
tried rebooting the AP, same thing. I tried 3.8.0 which worked before, it
behaved the same way. I also tried 3.9-rc4, same result. So now I was
without 5GHz for a 1-2 weeks, running only on 2.4GHz.
Then I installed and booted into Win8 to verify my hardware. Worked fine
with 5GHz. Then I booted back into 3.2.0-34, which then all of a sudden
worked fine, and now I am on 3.2.0-39 which is also fine.
Is there anything in Intel 5300 that can survive between cold boots that
booting into Win8 might magically fix, especially something that might
have been touched by recent changes in 3.2 stable and 3.8-3.9 ?
