    Wifi sometimes works and sometimes doesn't


    I recently installed linux mint 13 cinnamon. When i first turned on my computer no wireless networks were recognized. Then i rebooted and everything worked perfectly. After a few reboots (not all in the same day) no wireless networks were recognized again. I know my wireless is working because when I boot into windows 7 i can always connect to wifi. But with cinnamon it's random. Why does wireless only sometimes work? How do I fix this?

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    This sounds like a race condition to me. One assumes the driver is loading ok, but it is possible that the device is not initialized and runnable quickly enough for the network software (wpa_supplicant, etc) to access it when they start. You might be able to address this problem by disabling and then re-enabling the wireless networking in the Network Manager tool.
    Sometimes, real fast is almost as good as real time.
