Hi everyone,
I solved the problem while Intel is developing a new driver version. I done the following steps:
1- Uninstall McAffe software!
2- Install the last drivers from Intel
3- In the panel Control --> Hardware and Sound --> Power Options. Select "High Performance"
I'm working during 2 weeks and the wireless works perfectly.
Note: the "High performance" plan configures the wireless adapter settings (you can found it into Advanced settings tab) as "maximum power"
