My laptop is a Lenovo g530 running win 7. I installed SP1 on 2/8. My wireless was working fine on 2/10, which was the last time I tried to access the internet before today. Today, I can't connect to any networks.
Diagnosing the wireless says I need to turn it on, but when I press Fn+F5 there's no option to turn it on, just a window with the message "First switch on the wireless device".
I can't connect by plugging in an ethernet cable either; that just shows "unidentified network" and prompts me to power cycle the modem. I know the modem is fine because another laptop in the room is able to access the internet with wireless.
Everything looks normal in device manager.
How can I further diagnose the problem?
