Hi I have a Sony Laptop with Sandy Bridge chipset. I installed the new version of Ubuntu 11.10 because of I read that this release should have support for this chipset. In fact, almost all devices of my laptop are working fine, but the wireless card can not be enable. I found several links to older versions, but I guess all of them were design to work with kernels 2.X.X so I did not tried them. Is there any way to repair this at this time ?

This looks remarkably similar to the linked question below.

In your last trace - acer_wmi wireless kernel module is soft-blocked - this is causing the "DISABLED" message in the first trace.

Try blacklisting the acer_wmi kernel module as per the linked question and accepted answer.

  • WoW !!! This works perfect for me. Thanks a lot fossfreedom ! Just one more question. As long as I get updates I need to modify this configuration file again ? – Leandro Oct 13 '11 at 23:14

    no - since it is blacklisted you dont need to worry. However, just occasionally, remove the blacklisting to see if any newer kernels released fixes this bug. – fossfreedom Oct 13 '11 at 23:20
