    wireless is disabled by hardware switch - natty 11.04

    HI all,
    I'm running natty 11.04 and wireless was working properly till yesterday night. now is not possible to see any network.

    I'm on a dell inspiron 1545 and the Broadcom STA drivers are already installed.

    tried already a rfkill unblock all, but the results still this:

    Code:
    0: brcmwl-0: Wireless LAN
    	Soft blocked: no
    	Hard blocked: yes
    1: dell-wifi: Wireless LAN
    	Soft blocked: no
    	Hard blocked: no
    but the result of this command is changing all the time, few minutes before I got this one:

    Code:
    0: brcmwl-0: Wireless LAN
    	Soft blocked: no
    	Hard blocked: yes
    1: dell-wifi: Wireless LAN
    	Soft blocked: yes
    	Hard blocked: yes
    any idea how to solve this? tried to reboot couple of time without results.

    the weird thing is that yesterday night and from the very beginning never had an issue with the connection.

    Any idea? I think there are lot of people out there with the same issue isn't?

    This is the result of the outrageous f45up of wireless net drivers in 11.04 and I'm also looking for a permanent solution to this issue.

    So much for the great "let's eliminate paper cut bugs" talk...

    I know that some "software" wireless interfaces apparently need Windows 7 (or possibly Vista) in order to "enable" the hardware switch. If you still have a Windows partition (dual-boot), that might be worth a try.

    Also, it would be good to specify which Broadcom wireless interface (and configuration) you have by running the following terminal commands:

    Code:
    lspci -vvnn | grep 14e4
    
    sudo lshw -C network
    
    lsmod
    
    ifconfig
    
    iwconfig
    That said, Ubuntu 11.xx seems to have many recent "issues" with wireless and wireless firmware (I'm still using Ubuntu 10.04.2 LTS and the Broadcom STA driver and it works quite well "out of the box"). :/

    Unfortunatelly (or not ) it's a single system machine. Here's the terminal return of all the commands you listed:

    Re: wireless is disabled by hardware switch - natty 11.04

    With due respect to my colleagues, I think it's due to a poor implemetation of the module dell-laptop. Please do:
    Code:
    lsmod | grep dell
    If dell-laptop is loaded, remove it:
    Code:
    sudo rmmod -f dell-laptop
    sudo rfkill unblock all
    Is your wireless working now? If so, we'll need to blacklist dell-laptop.

    Hi Bucic,

    Yours is a Broadcom 4318 AirForce One wireless, and post #27 on the following thread seems to have recently worked for those:

    http://ubuntuforums.org/showthread.p...om+4318&page=3

    This is also a very informative thread about Broadcom 4318's and firmware:

    Under what name do the non-proprietary BCM4318 drivers show up in lsmod?

    i have been having the same problem with wireless, and so have followed this discussion. I can confirm that the last proposal (removing dell_laptop) *did* fix the issue.

    Looking at Bucic's lsmod output, I don't see ANY Broadcom modules loaded. (Also, I don't see any Dell modules loaded there, and it might actually be a HP based on the module "hp_wmi" that I see loaded above- and it appears keymap-related.)

    The Broadcom 4318 should have "b43" "b44" and/or "ssb" modules from what I recall- see the thread that I linked above (but I don't see any of those modules loaded from what Bucic posted). Their absence makes me think that Bucic should probably follow that Broadcom 4318 thread through step-by-step from the beginning.

    FYI- my working Broadcom STA wireless (Broadcom "4321AG" under Vista 64bit and "4328" under Ubuntu 10.04.2 LTS) has these modules loaded:

    wl 1964968 0
    lib80211 6151 2 lib80211_crypt_tkip,wl

    The LED indicator is up but wireless is still not listed in the networking applet, not even after disconnecting the LAN cable and disabling/enabling networking.
