    Wireless Disabled Broadcom BCM 4312, Dell Vostro 1700

    I have a Dell Vostro 1700 with the Broadcom BCM4312 card (obviously). Running 10.04.

    Earlier today the wireless was working fine, then after a reboot, it stopped. I have the Broadcom STA wireless driver installed already, and have read all the other applicable threads on the forums pertaining to my situation and tried various fixes posted, all to no avail.

    I can access the internet via wired tethered connection through my Droid, and it doesn't detect the wireless tether, again, obviously. I have my wireless switch on, and 'rfkill list' returns:

    matt@ubuntu:~$ rfkill list
    0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
    1: dell-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: yes
    3: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

    When its switched off, it returns:

    matt@ubuntu:~$ rfkill list
    0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    1: dell-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
    3: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

    Oddly it appears to be open when it's off and blocked when it's on. When the wireless switch is set to off I can search for hidden networks, and it finds my network when I type it in or use the one I've set in already, but it just sits at connecting and repeatedly asks for my passkey (which is inputted correctly). After three tries it says 'wireless disconnected'. When the wireless switch is set to on, it says my wireless is disabled.

    Here's the iwconfig: (tethered to my phone)

    matt@ubuntu:~$ iwconfig
    lo no wireless extensions.

    eth1 IEEE 802.11 Access Point: Not-Associated
    Link Quality:5 Signal level:0 Noise level:0
    Rx invalid nwid:0 invalid crypt:0 invalid misc:0

    usb0 no wireless extensions.

    eth0 no wireless extensions.

    pan0 no wireless extensions.

    Output for sudo lshw -C network: (again, tethered to my phone)

    Sorry for the long post, I just wanted to cover most of the commands that are usually asked here. And this question has been asked a million and half times, but none of the situations have been quite like mine and all the 'fixes' I tried didn't help. Drivers are installed, and have been reinstalled numerous times. Help?

    Thanks

    I have the exact same problem with my Dell 1520. Did you ever find a solution?
