    wlan0 blocked by rfkill

    Heya, I updated my laptop with a fresh install of 10.10 this morning. Everything seems to be working fine besides the wifi. I've browsed through this forum section and Google and tried some various solutions but I can't get it to work. I found some output requests so I'll begin by posting my outputs from those and hopefully someone can help me easier.

    Code:
    $ sudo lshw -C network

    I can't enable wireless networking in the network manager since it's greyed out. I tried setting WirelessEnabled=true in /var/lib/NetworkManager/NetworkManager.state and then restart the network manager but that didn't change anything. I also tried wicd instead of NetworkManager -- no luck.

    I ran the following to see what happens when I press the wifi button on my laptop:

    Code:
    $ sudo rfkill event
    1288606442.348538: idx 0 type 1 op 0 soft 1 hard 1
    1288606442.348589: idx 1 type 1 op 0 soft 0 hard 0
    1288606447.036105: idx 0 type 1 op 2 soft 1 hard 0
    1288606448.748096: idx 0 type 1 op 2 soft 1 hard 1
    1288606450.209440: idx 0 type 1 op 2 soft 1 hard 0
    1288606453.179616: idx 0 type 1 op 2 soft 1 hard 1
    However, it's permanently glowing blue. The laptop is a Compaq Presario CQ70. Does anybody know how to solve this issue? I really appreciate any help I can get with this.

    Re: wlan0 blocked by rfkill

    You have a hardware switch blocking the device. Is there a switch that turns it off/on ?

    Yes, the button is constantly glowing blue and pressing it doesn't seem to work. It should be blue when enabled and red when disabled.

    My only guess is the switch is defective or is Windows dependent. If you dual boot check and see if you can activate the switch via Windows.

    I am not sure that I agree that the switch is defective. Is there any improvement if you do:
    Code:
    sudo rmmod -f hp-wmi
    If it helps the switch work correctly and enables your wireless, we will need to modify one file to make it permanent.

    I ran rmmod -f hp-wmi and the nic changed from "not ready" (I think) to "disconnected" in the network manager. The switch still doesn't work.

    I proceeded with ifconfig wlan0 up, got the "Operation not possible due to RF-kill" again, ran rfkill unlock all and then rfkill list, that outputs that phy0 is neither soft or hard blocked. iwlist scan says that wlan0 has no scan results but there are plenty of networks in the area that should be detected.

    The switch isn't defective, it flashes properly between red and blue at the laptop's boot process. wifi access has been working in previous versions of Ubuntu.

    Thanks for your replies guys!

    I have this same problem that I reported just a little bit earlier.

    http://ubuntuforums.org/showthread.php?t=1610928

    My system (10.04) was working fine and then suddenly stopped working. I suspect one of the recent updates (in the past two weeks). I upgraded to 10.10, but the problem continued.

    I also just installed a fresh 10.10 Ubuntu to a laptop that was running Windows7 before I got it. I am having the same issue as the OP. Here is my output from rfkill list:
    Code:
    1: phy0: Wireless LAN
    	Soft blocked: no
    	Hard blocked: yes
    Here is my relevant output from sudo lshw -C Network:
    Code:
