This probably intended for Lenovo personnel specialists but still, maybe someone encounter a similar problem?
So, x121e (304579G) UEFI only option + GUID partition table (GPT) + Pure UEFI windows 7 pro 64bit install, and no luck with wireless lan drivers. Everything else seems work perfect.
I tried to install drivers from TVSU, and from Intel site. Did Nothing. Problem is that after every restart, Wireless adapter in device manager get yellow warning mark, and 2 Microsoft miniport adapters disappear. Only way to get it back, uninstall, then scan for changes and system install same driver again. (every mini port adapter gets names wit +1 index). Adapter work again fine. Until.... Next restart. Found similar problem on German forums, but was very hard to read. So any tips, ideas?
By the way, why drivers from TVSU not install mywifi technology pack? Widi not work without that. And if I try install it from Intel official setup, it update driver too. So no point install it from TVSU.
