I have the M5-581T-6807 laptop.  I did a fresh install of windows 7 x64 on it.  Since it was a windows 8 laptop I have updated the bios to 2.09 and installed Atheros 10.0.0.42 driver.  Anytime I close the lid and it goes into sleep mode and I wake it up, the wireless is gone.  If I do a restart it doesn't come up.  But if I do a shutdown and start it up, it works everytime.  I am thinking that the issue might be with the bios.  Since I have windows 8 bios installed on a windows 7 OS.  The windows bios is 1.12, I have tried to install it, It tells me that I can't downgrade.  Any help would be great.
