it is very easy. Intel or Microsoft did failed with drivers for Intel mini-PCI cards for Windows 8.1 64bits. All Intel mini-PCI cards has problems with drivers for Windows 8.1, from my experience it is n2230, and 6235 and many others too.
You need to downgrade do Windows 8 or change the mini-PCI card to Realtek or Qualcomm.
Same as my case, I need to downgrade or change the mini-pci adaptor.
Yes. Exactly. According all I did read about the issue with Intel mini-PCI and Windows 8.1 64bit, it looks like the only way is to downgrade to Windows 8.
Downgrading to Windows 8 did solve this issues for many or all users, that has similar issue.
I am going to try the downgrade to Windows 8 today also.
Problem has users whos hardware do not have official preload with Windows 8. I have same issue with Sony, as the preload is Window 8.1, but I can use and install clear Windows 8 and after install all other Sony software. Not every users is capable of this.
I understand that users, who do not have Windows 8 preload and do not know how to reinstall Windows 8, return their hardware to its seller. This is option 2 of this Intel driver issues.
I believe I have a preload of Win8 on mine, but I am a little concerned I am stuck on that level forever.
Its a pretty new laptop (Warranty Enddate +2 months, unfortunately) with Intel SSD and lot of RAM etc.
Let me hear your experience in downgrading.
I will peruse the driver install problem a bit more.
I wonder why I cannot get a driver pack without an Installer on top of it. Some of us are old enough to know how to move around with device driver settings etc.
and thanks for sharing, btw.
