["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

steros, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete

Title:
  no power management for Intel(R) PRO/Wireless 3945ABG/BG

Status in The Linux Kernel:
  In Progress
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have no power option for my wireless adapter. Especially when on AC this gets very hot (nearly unusable).
  In Windows I can lower transmission power which helps.
  I am under the impression in earlier versions of Ubuntu I was able to do that too (or through some tools).
  Now it seems to be gone.
  To my research it seems that the original drivers "ipw3945" have been replaced by newer "iwl3945"?
  Maybe thats the cause?

  additional Information below:
