Freeze with wlan-card disabled/enabled

Computer: Samsung 530U, NP530U3C-A07SE

So we got this computer brand new with Windows 7. We wanted Windows 8, and performed an clean install of Windows 8, manually formatting the partitions, meaning deleting of every recovery partitions and so on. W8 booted fine, and everything worked fine, installed new drivers through Samsungs own "Windows 8 SW update"-software. Installed new updates through windows update, and everything seemed to work just fine.

But then, suddenly when the PC have been left alone for a while, and I think I can provoke the same issue by hibernate and start up again, the wifi can't connect to the wireless network, which the networks router could be found 1 meter aside. You then get the "network available"-symbol, and we can go on and try to connect to the network. The PC tries to connect for a while, and then it seems to just kill the wlan-card, like it has been disabled, and now the PC freeze. We now have to hard-reboot it, and wait for login, and then clean reboot it, and then again at login everything works fine. To the next time the PC have been left alone.

So the problem look like this; hibernation->wifi connection lost->wifi available->re-connecting to wifi->wlan-card disabled->PC freeze

What we have tried is to uninstall all wifi-drivers, install different drivers, from Samsungs site, windows pre-installed drivers, driver software-drivers and so on. Just to add, we also have this 7 series computer from Samsung, everything works fine.


Have anyone else been dealing with the same problem/or have any suggestions? Can anyone suggest a software to log what's happening with the computer before it crash/freeze, because I can't seem to find anything from the Windows Event Viewer.

Thanks in advance.
