    This means your wireless "switch" is off. If you don't have a physical "slide" or "toggle" switch, in most HP notebooks, the wireless light is also a touch sensitive switch. Just swipe your finger over the wireless indicator and it should be enabled again.

    I have the exact same problem using Puppy Lucid 5.2 which is based on Ubuntu repositories. The problem is that my install CD did not have the necessary microcode driver iwlwifi-6000-4.ucode or something like that. I found version of this microcode that matched my kernel version, 2.6.33.2, and copied the microcode to the file system using the puppy package manager. Upon reboot my wireless was enabled and I was able to connect to my router.
