joe_intel,
I tried 15.8 and had the same issue! Something Intel has introduced in 15.6 and higher is breaking the Windows networking stack upon installation! I am now living in fear that any PCs in my organization get these drivers without my approval as if I don't catch the problem in time to do a System Restore, I have to wipe and re-install the whole PC!
Please look into this issue further!
Some further info about the configuration of the Lenovo ThinkPad X230 that I have this issue on:
- Windows 7 Enterprise x64
- UEFI boot
- Intel vPro enabled on wired and wireless interfaces
- BitLocker disk encryption using TPM (note: I did encounter the problem without BitLocker being used too)
