WiFi does not function on Acer 1830T with 11.04

[Craig Nelson]

Acer 1830T-68U118 - Wireless functions fine with Ubuntu 10.10 / Win7 dual-boot but fails with Ubuntu 11.04

WORKAROUND:
cat /etc/modprobe.d/blacklist-acer.conf
blacklist acer_wmi

sudo lshw -C network; lsb_release -a; uname -a; rfkill list

Try to blacklist module 'acer_wmi' as described in :
https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/689529/comments/20
Please add a comment on whether it helps.

[Craig Nelson (cankwn-sc)]

Wladimir,

Blacklisting acer_wmi as you suggested corrected the problem
Thank you for your expert and very quick response

[RedSingularity (redsingularity)]

Assigning to the linux kernel.

I tried blacklisting acer_wmi as described - but it did not seem to help.

As I reported above, following installation of kernel - 2.6.38-10-generic-pae the wireless started working.

[richard mullens (richard-mullens)]

Hi,

You requested the following - which I then performed. I also set the status
to "New"

Your response was to issue the message again and reset the status to
Incomplete.

Why ?

The original bug reporter seems not to be subscribed - so he won't do it.

The problem appears to be resolved with a more recent kernel.

[richard mullens (richard-mullens)]

I just applied updates on return from abroad, and now the wireless is broken again.

Linux richard-1830T 2.6.38-11-generic-pae #48-Ubuntu SMP Fri Jul 29 20:51:21 UTC 2011 i686 i686 i386 GNU/Linux

[richard mullens (richard-mullens)]

I restored wireless operation by

dpkg --list | grep linux-image
Then
sudo apt-get remove linux-image-2.6.38-11-generic-pae
and rebooting.

Now I have

dpkg --list | grep linux-image
ii linux-image-2.6.38-10-generic-pae 2.6.38-10.46 Linux kernel image for version 2.6.38 on x86
rc linux-image-2.6.38-11-generic-pae 2.6.38-11.48 Linux kernel image for version 2.6.38 on x86

ii linux-image-2.6.38-9-generic-pae 2.6.38-9.43 Linux kernel image for version 2.6.38 on x86

and System Monitor says Kernel Linux 2.6.38-10-generic-pae

[Julian Wiedmann (jwiedmann)]

Craig (and anyone else affected),
could you update your kernel to 2.6.38-11.48 and test whether blacklisting acer_wmi is still required?

[penalvch (penalvch)]

Craig Nelson, thank you for reporting this and helping make Ubuntu better. 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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

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

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

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Anyone else who may have the same or similar problem, please file a new bug report via the Terminal and your welcome to subscribe me to it:
