Hi ! I have installed 9.04 Netbook Remix on my Aspire On A531h. The tickbox for Enabling Wireless in the Network manager is greyed out.

I think it has to do with the WiFi "killswitch" on my hardware. It doesn´t seem to have any effect at all, so propably it is not supported in Ubuntu.

I use the standard driver, not the "madwifi" that is also included.

Has anyone experienced the same and know what to do? Can the wifi be enabled/activated with command(s)?

BR /miika71, newbie

Wouldn't hurt to take a look at your configuration and find what's causing the problem to begin with. Might be it's as simple as bringing the interface up or then not. So, open up a terminal, run lshw -C network and post back with the output.

This is the output from lshw -C:

Another thing worth mentioning, I downloaded RutilT WLAN Manager, and with that applicationit is possible to scan and detect networks using wlan0, but I can not activate it in the Network manager to use it to connect to the networks.So, the interface seem to be alive, but I can not use it.

Hi, how can I check if the Acer_WMI module is loaded?

lsmod | grep acerIf its blank then it isn't that.

It seem to be there!
What should I do?

You can remove it (temporarily) by
sudo rmmod acer_wmiIf it helps then blacklist it.

Damnit! It worked! Thanks a million! How do I do to blacklist it? Will it then be disabled when I reboot as well?

ddrichardson
June 3rd, 2009, 10:04 PM
Edit /etc/modprobe.d/blacklist.conf and add a line:
blacklist acer_wmi

I meant to say, keep an eye on automatic updates because this will likely change in the future. The acer_wmi module doesn't inhibit on my current kernel (I'd say the number but I can't be nadged to go up stairs, turn it on and type uname -r to find out what the current Arch kernel image is).

Glad it fixed it for you. Its been surprising how many times updates have caused me problems on my Aspire One.
