    Wifi suddenly stopped working


    So being first time Linux user, I've installed Ubuntu one my laptop (Compaq Presario CQ60). Everything worked great right out of the box for few weeks. Then suddenly wifi stopped working. I'm not aware of any changes or anything I would do that could cause this.

    I'm running release 10.10.

    iwconfig says:

    lo no wireless extensions.
    eth0 no wireless extensions.
    wlan0 IEEE 802.11bg ESSIDff/any
    Mode: Managed Access point: Not-Associated Tx-Power=off
    Retry long limit: 7 RTS thr: off Fragment thr: off
    Encryption keyff
    Power Management: off

    The laptop has dedicated wifi on/off button. This button indicates wifi is on. However pressing it has no impact (as it used to under Windows) and no effect on iwconfig output.

    Other laptops are able to use the wifi router, so it is not problem with the router.

    I've tried few things I could find on this forums but with no luck.

    Any help would be appreciated.

    Ok, so

    rfkill unblock all

    fixed the issue.

    Why? What does this command do?
