Hello Ryan, Thanks for your response.

My AP is in the same room that I use my notebook, it's right in front
of me. There's no specific scenario for this failure to happen.
Sometimes it does not happens for days, but sometimes it happens 3/4
times in the same day.
It looks like that there is not specific scenario, sometimes it
happens while I'm using firefox, sometimes it happens when my laptop
is "doing nothing". (Was it helpful?)

I'm using WiFi 802.11n, 2.4ghz with AES.

I'll try this new firmware/driver.
