    Enable Wireless - unchecked and greyed out

    Hi everyone,

    I'm hoping you can help with a query. I'm running Ubuntu Linux 9.10 and have been connected to my wireless modem/router (linksys) without any trouble.

    Until today, when I foolishly decided to change my system password. I was prompted for my network password which I thought I had correct, but apparently didn't. Now, when I click on my icon for internet connections the 'enable wireless' button is unchecked, and greyed out, so I can't click it back on.

    I logged into my modem/router and re-set the password, and that's all okay.

    In the meantime I'm connected via the cable to the router.

    I checked the settings and my network is disabled as per below. I've unplugged and restarted the linksys, and also my laptop several times.

    I know this set up works, I just need to find the 'switch' to turn the wireless networking back on.

    Thanks for your help!

    That's exactly what it looks like. Please post:
    Code:
    rfkill list
    Thanks.

    Yes! This means there is a hardware switch or slider somewhere on your laptop that switches the wireless on and off. It is switched off.
    lisa@lisa-laptop:~$ rfkill list

    Find it, switch it and be back in business.

    Re: Enable Wireless - unchecked and greyed out

    I have the exact same problem!

    The command
    Code:
    rfkill list
    gives the following for me:

    Wireless Hardware Switch On
    0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no


    Wireless Hardware Switch Off
    0: dell-wifi: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
    1: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes


    Wireless Hardware Switch On Again
    0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
    1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no


    Wireless Hardware Switch Off Again
    0: dell-wifi: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
    1: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
    and so on....

    Any idea why this is happening? I have another Gateway Laptop where I have no problems at all connecting to wireless networks. So is this some driver problem or a bug?

    Any quick fixes?

    I'm on Ubuntu 10.04 and my Wireless Card is:
    Intel Wireless 6200 AGN

    Re: Enable Wireless - unchecked and greyed out

    I have a Dell Inspiron 1720 where, if I reboot my computer with the wifi switch turned ON, I cannot connect to any wifi networks, the "enable wireless" is unchecked and grayed out. However, if I make sure to have my switch in the OFF position when it's rebooting, once I log in, I turn ON my wifi and I am able to connect. It really sucks having to remember to turn off my wifi, or even worse, having to reboot my computer just because I forgot to turn it off. This happens to me with both Broadcom drivers. Here are some outputs:
    Code:
    lspci | grep Broadcom
    03:00.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
    0c:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
    Code:
    rfkill list
    0: hci0: Bluetooth
    	Soft blocked: yes
    	Hard blocked: no
    1: dell-wifi: Wireless LAN
    	Soft blocked: no
    	Hard blocked: yes
    2: dell-bluetooth: Bluetooth
    	Soft blocked: yes
    	Hard blocked: yes
    Any help is really appreciated.

    EDIT: After reading a few more posts, I found that by running "sudo rmmod -f dell-laptop" I am able to turn on the wifi.

    Re: Enable Wireless - unchecked and greyed out

    I have a similar problem, following a re-installation of 10.04.
    Wireless Network in Network Manager is greyed out and not enabled:

    lshw -C network

    My WiFi switch (keyboard/LED switch) does not light up when I turn it on and off:

    rfkill list
    0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
    andy@ubuntu-laptop:~$ rfkill list
    0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

    The wireless hardware is enabled at power on and not disabled in the BIOS.
    It works perfectly when I boot Windows, and also worked perfectly with my previous Ubuntu 10.04 installation.

    I have even reinstalled 10.04 while the wireless was toggled 'On' and it made no difference.

    Re: Enable Wireless - unchecked and greyed out

    When visiting my sister recently, I checked out her laptop (make not noticed). Her daughter had put a stickly label on the top of the screen saying "switch off wireless." I guess there was a reason for this. By the way, the OS is Vista. So, this problem of needing to switch off wireless in hardware before re-booting might not be a Ubuntu problem.

    regards
