Not sure if this is the right place to post this, because I'm not sure what has happened, I'm Nurssing student trying to study for a 2 huge test via my ASUS U 80 Laptop. (going crazy sitting at the desk all the time) any way everything fine was on laptop via wirless modem, Lost the wireless signal (I have verified it is still available) ran a trouble shoot on laptop which tells me the no wireless signal available wireless turned off. I click over on the wireless controls to turn it back on and --- it won't let me turn the wireless back on. Could it be that the wireless card has stopped working altogether? Help---Desperate! Any ideas???? At least I can keep studing on my desktop but must have laptop up before school on Tues. next.
