Lenovo B490 Laptop Wireless LAN Driver
Few days back My friend used my laptop in my absence and after that I am not able to connect internet through the H490 port. I think that the auto-negotiation part is now working well. Still “network controller” appears in device manager as an unknown device. Vinga the same problem on a lenovo y I could use a little help with my new laptop – I installed Windows 7 64 and all the drivers I could find on the drivers page, and still, it can’t use my wired network.
Hello, I have the same problem, not with my ethernet controller but my network controller.
