    Wireless is no longer functioning

    My gazp5 has suddenly lost all wireless capabilities. I have no idea why, the wireless just doesn't detect other networks. Here's the output of:
    dmesg | grep wlan0

    Re: Wireless is no longer functioning

    1. Make sure your wireless toggle switch is on (slide it to the right).
    2. Follow these instructions to ensure your interfaces file isn't hosed...

    To fix your /etc/network/interfaces file, go to a terminal
    (Application > Accessories > Terminal) and enter the following command:

    sudo gedit /etc/network/interfaces

    This will launch a text editor with the interfaces file opened in it.

    In this file, put a comment (#) in front of EVERY line of the file
    EXCEPT for these two lines:

    auto lo
    iface lo inet loopback

    Click SAVE on the text editor and reboot your computer.
    It should now boot faster and connect to networks more easily.

    NOTE:
    Unless you are dealing with static IP addresses (which is pretty rare for the
    general end-user) you should NOT establish a network connection by going to
    System > Administration > Network.

    Instead, you should connect to the Internet using the Network Manager icon
    in the upper right corner of your screen (the one that looks like a little
    computer monitor).

    Re: Wireless is no longer functioning

    All of those things were done prior to my previous post (based on previous threads), also I always use the network manager for connecting to a network.
    The reason I posted this as a new thread is that it is intermittent, sometimes I just have to force it to connect to a network, or put in a hard connection then it starts working again. It only seems to occur when I try to connect to some nebulous networks near my work place. They are 'unsecured' but never let me connect.

    The doctor can't fix it if he doesn't know the symptoms.

    Re: Wireless is no longer functioning

    On the Intel 4965 I've got this not functioning wifi is somehow related to the recent kernel updates. wireless is fine with 2.6.24-16 but cant connect (same error as OP) with 2.6.24-18 or -19
