[Bug 876147] Re: Intel Corporation Centrino Wireless-N + WiMAX 6150 (rev 67) not working after upgrade to 11.10


iFreeBudget, 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 (not the daily folder, but the one all the way at the bottom) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. 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:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

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:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

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

Bug description:
  I had a pretty stable Natty install, but then I went and upgraded to
  11.10. It went downhill from there. Most of my problems I am about to
  describe are covered in various threads but none of the solutions have
  worked for me.

  I have a Asus laptop model no: U56E-BBL5 with 6gb RAM, Intel core i5

  1. Wireless/wifi stopped working. Outputs from various commands
  suggested in other threads are pasted here

  [/CODE]So, wireless is completely not working now and I have to sit near by shoe closet on the floor to get a wired connection to post this.

  2. Suspend hangs the system.

  Whenever I suspend or system goes to suspend due to inactivity, the
  system completely freezes. Only a hard reset is possible at this time.

  3. System is generally slow and unreliable. Only saving grace has been
  Gnome3.2 which looks rather neat.

  Any help is greatly appreciated and any one else having same problems
  please give a shout. I would feel a little better knowing that I am
  not alone having these problems.
