I was viewing a clip on YouTube at home today and all of a sudden my wireless connection disappeared. No wireless networks are detected anymore. Nothing else was running, I was not doing anything else except having my browser open.
I haven't installed anything lately, nor have I made any system changes. There is no malicious software on my laptop either, you can be sure about that.
My cell phone has Wi-Fi support and it does pick up all the networks available, including my router. It's definitely my laptop.
I don't see anything worth mentioning in the Event Viewer.
It is not the wireless on/off switch button either (it's always on anyway).
What I find odd is that my mouse pointer started freezing from time to time which I suspect is happening when network scan is performed.
Could it be a hardware problem (I haven't had a NIC fail on me ever though)? Any diagnostic tips?
EDIT: The model is Asus F5RL.
