Wi-Fi in my laptop (intel wireless3945 abg) turns off randomly (hardware turn off) it disappear from hardware list and its light is going off. I think that it is going down when my computer starts to save power and turning it off for a moment, then it cannot bring it back again.
When I click on button that turn off / on wi fi. I can turn off but then I can not turn on. Sometimes option find new hardware in Hardware View helps and wi fi is being reinitialized (but it is rarely thing).
Do you have and Idea what should I do I have drivers from 15/09/09. Version 18.104.22.168.
I unchecked option that lets turning off wi fi in Hardware View under Power Management (Allow the computer to turn off this device to save power).
The same on windows xp and windows 7
I think that it might be some problem with drivers because when I restart my computer wifi sometime is working and sometime not. But when I hibernate / dehibernate it always works.
