I've been able to connect to the internet for over a year on my Inspiron 1545 laptop using Windows 7. Recently I had to reset my router because I got a message that it was insecure. When I enter the new password the router gives me, I get a message "The wireless radio is off." I push the F2 button and the antenna icon flashes on the screen. Repeated this. I tried pushing the Fn + F2 but nothing happens. I've tried several times, restarted, etc. to no avail.

I bought the laptop with Windows Vista and upgraded to Windows 7 if this matters.
I checked all the devices in Device Manager and they are say they are working properly.
Anyone have any ideas on how to connect the wireless radio?
