    Unhappy Cannot enable Realtek wireless on Toshiba Satellite Pro L500 in Ubuntu 11.04

    I have just installed Ubuntu 11.04 on my brother's Toshiba Satellite Pro L500 and have spent all day trying to get the wireless to work. I am fairly new to Ubuntu (have played about without getting my hands dirty for a while), but I have tried everything I could find in the threads and still cannot solve the problem, so here goes...

    the laptop does not have a physical wifi-switch (it should switch on-off with Fn+F8, which doesn't work), the drivers seem to be installed, but I cannot 'enable wireless', and I found that it is 'Hard blocked':
    sudo rfkill list all
    :
    0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

    but 'rfkill unblock all' does nothing.

    Some people mention that certain wireless devices might need to be switched on in another OS, but this is not an option, as I hastily removed Windows and have no way to re-install it.


    Below, I put all sorts of information (which I only partly understand, but saw was advised in a 'How to post about wifi' thread):

    Let's have a look at:
    Code:
    lsmod | grep wmi

    Hmmm. No acer-wmi or similar. Let's see all of:
    Code:
    lsmod
    Something should be driving your hotkeys and isn't doing so correctly.

    Regarding the hotkeys (you mean my Fn+F8 that should toggle the wifi?), all the other Fn+... (sound, etc.) work, so I thought it was a driver or some other similar problem (admittedly I am in deep waters, and don't really know).

    Re: Cannot enable Realtek wireless on Toshiba Satellite Pro L500 in Ubuntu 11.04

    Have you tried:
    Code:
    sudo rfkill unblock all
    Please do:
    Code:
    sudo tail -f /var/log/syslog
    Leave the terminal open as you manipulate the switch. Are there any interesting messages that appear in syslog?

    Are you certain the Fn+F8 key is not a multi-function switch? That is, one press is bluetooth, second is bluetooth and wireless, third is wireless and fourth is none. I have one of those keys on my IBM T40.

    Re: Cannot enable Realtek wireless on Toshiba Satellite Pro L500 in Ubuntu 11.04

    I have tried
    Code:
    sudo rfkill unblock all
    and variations, e.g. rfkill unblock wifi
    then I would always check
    Code:
    sudo rfkill list all
    and always get:

    0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
    2: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
    regarding syslog: I tried what you said, but it would not react to me pressing Fn+F8, or any other Fn combination. It did give the following (every time):

    May 13 00:41:54 ArjanPro kernel: [17727.437705] atkbd serio0: Unknown key pressed (translated set 2, code 0xbd on isa0060/serio0).
    May 13 00:41:54 ArjanPro kernel: [17727.437709] atkbd serio0: Use 'setkeycodes e03d <keycode>' to make it known.
    May 13 00:41:54 ArjanPro kernel: [17727.445189] atkbd serio0: Unknown key released (translated set 2, code 0xbd on isa0060/serio0).
    May 13 00:41:54 ArjanPro kernel: [17727.445193] atkbd serio0: Use 'setkeycodes e03d <keycode>' to make it known.

    May 13 02:02:32 ArjanPro kernel: [22564.871197] atkbd serio0: Unknown key pressed (translated set 2, code 0xbd on isa0060/serio0).
    May 13 02:02:32 ArjanPro kernel: [22564.871204] atkbd serio0: Use 'setkeycodes e03d <keycode>' to make it known.
    May 13 02:02:32 ArjanPro kernel: [22564.878753] atkbd serio0: Unknown key released (translated set 2, code 0xbd on isa0060/serio0).
    May 13 02:02:32 ArjanPro kernel: [22564.878777] atkbd serio0: Use 'setkeycodes e03d <keycode>' to make it known.
    May 13 02:17:01 ArjanPro CRON[5406]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly)
    the last entry being almost an hour old.

    Also,
    I am pretty sure Fn+F8 is not a multi-function switch. I have checked this by seeing if anything changed in 'rfkill list all' and in the networks icon in the tray when I pressed it, but nothing. Should\can I check what the combination is mapped to? and how?

    just to say that I'll be out of action for a while (bed time), but thanks for your help so far!

    Re: Cannot enable Realtek wireless on Toshiba Satellite Pro L500 in Ubuntu 11.04

    At least for now, I am stumped. Let me sleep on it.

    I wonder if this helps us: /etc/acpi/events/tosh-wireless and /etc/acpi/tosh-wireless.sh

    In this case, tosh refers to Toshiba.

    See you tomorrow.

    Re: Cannot enable Realtek wireless on Toshiba Satellite Pro L500 in Ubuntu 11.04

    Please try:
    Code:
    sudo modprobe omnibook wifi=1
    Now does Fn+F8 work?

    Please see:
    Code:
    modinfo omnibook
