this affects me too. I am using ubuntu 11.10 on my dell studio 1558. It keeps saying that device is not ready. The only workaround i can find is to uncheck the enable networking option from its menu and then re- enable it.

On this machine, if I use the wireless hotkey combo to turn wireless off once, I am able to turn wireless back on again. However, on the second and subsequent attempts to turn wireless off and on using the hot key combo, the wireless remains disabled. The only recovery is to reboot the machine. This machine does NOT have a physical slider, only the hotkey.
