    Wireless stopped working after Ibex update


    A few hours ago I took my updates for Ubuntu Ibex, rebooted per the instructions, and when I came back up, my wireless wasn't working.

    I can open Network Configuration and see the networks I connected to in the past. The settings are still correct and all looks good with my router settings.

    When I rightclick on the networks icon in my desktop panel, both Enable Networking and Enable Wireless are checked.

    When I left click on it, I don't see the available networks like I used to before the reboot, and the Wireless Networks menu item is disabled.

    I tried re-adding my network, rebooting, disabling and re-enabling things, but no go. Am I just missing something?

    My Atheros card was problematic before but since I upgraded to Ibex, the wireless was working smoothly and as expected. The help topics I've come across don't seem to have my particular mix of issues. I appreciate any ideas.

    There is reportedly an app in Jackelope and Ibex which functions like 'System Restore' in Windows. Whether or not is it enabled by default I don't know. I don't know the name of it either...

    I believe also there is a way to view and to undo updates by history.

    When you update, the kernel is often updated too. Device drivers are usually kernel modules, and depending on how the driver was installed, may not be present in the new kernel.

    I would suggest reading the post linked to below, and then posting the info that it tells how to find.

    http://www.linuxforums.org/forum/wir...tart-here.html

    Without this info, we can only guess at the best way to fix it.

    You have the first command wrong, it is with two "n"s.

    Anyway, it looks like it is loading the ath5k module for your card. But it does seem to be deactivated. Is there a switch or key combination (Fn + F?) to turn the wireless on/off? Try that first.

    Yay!

    I do have Fn + F8, but this hasn't worked in linux. I also have a mechanical Wireless On/Off switch on the front of the laptop. I flipped this off and back on before with no results, but after what you said I played with it more. I turned it off, rebooted, shut down, turned it on, and booted up again. The Network Manager applet asked permission to use the keyring, and voilá!

    Thank you very much for the help.

    The newer kernels have support for wireless on/off switches and the shortcut keys. The on/off switch is covered by the rfkill module, the shortcut keys are usually covered by a module specific to your laptop brand. There may be a toshiba module that covers this.

    Glad to hear that you got it working.
