I have a Lenovo Edge E31 notebook with AMD chipset. I used this PC with Win7, it worked properly. I tried to install Win8. When I installed, it found every hardware, and installed drivers automatically. But When I first restarted the machine, my WIFI-card disappeared. In Device Manager I can find the card, but when I open the properties, there is an error code (10), "The hardware doesn't exist". I tried a lots of drivers, but nothing happened. Aida doesn't see my WIFI card too. When I delete the card, and reinstall it, it works good until the next restart. If I delete my common PCI-E hardware from Device Manager, and the machine restarts, WIFI works too. It looks like my motherboard cannot turn the card on. I think that I need a driver update for my chipset, because every hardware I have has a "standard driver". I think it's a ks880m chipset. Can I find a driver for it?
I have the same problem with my bluetooth too, just I don't care about BT. In Power Management, WIFI has maximum performance, PCI-E's power safe is off. In BIOS WIfi is always on. Of course I have a hotkey to turn it on/off, but it can tudn it off, but not ON. If I turn off wifi by hotkey, I can just tudn it on when I remove PCI-E from device manager. Of course, I have to do this after all restarts. The problem is just with Win8. When I take in a HDD with Win7, I don't have this problem.
Any idea? Or a driver?
