    Question WLAN don't work on laptops without wlan switch

    Hello!

    It seems that the wlan framework don't work well with older laptops that don't have a wlan switch to enable/disable the wlan.
    I'm using Ubuntu 9.10...

    I have a ASUS L5800C with a Broadcom 4301 chip
    rfkill reports the following:
    0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes

    After pressing Fn-F2 on the keyboard it changes to:
    0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

    I'm unable to switch the "Hard blocked" to "no". So the b43 driver show's the following messages in the dmesg (see the "Radio hardware status changed to DISABLED" line!):

    Is there any way or patch for this issue !?

    Thanks

    The reason why nobody has replied is that no one has anything positive to add on this subject !!

    Re: WLAN don't work on laptops without wlan switch

    I have found the "solution" myself.

    The solution was to recompile the kernel without RFKILL option.

    Maybe in the future there is a better way...

    Re: WLAN don't work on laptops without wlan switch

    Hi giacos73, I have the same laptop and same problem since I upgraded
    kernel to 2.6.30,31,32.
    This thread may be of interest for you:
    https://lists.berlios.de/pipermail/b...ry/006928.html

    I still haven't tried the compile-time disabling of rfkill (doing next).

    Hi;

    I've been suffering from the same thing. How did you manage to recompile the kernel without RFKILL option? Would you please give some detail?

    With a Broadcom 4306 mini-PCI card I had success masking pins 11 & 13 with cellophane tape. Now always on in a laptop that has no hardware switch.

    Re: WLAN don't work on laptops without wlan switch

    I'm having the same problem on an HP Pavilion zx5000 equipped with a BCM4303 rev. 2.
    The laptop has a toggle switch to disable wireless, but it is useless in Linux (Xubuntu 9.10): its light remains off, confirming that the wireless network adapter is indeed turned off.
    When running Windows, wireless works upon boot-up, and that switch works too, if i choose to use it.
