Lenovo G50-70 (i3) ETHERNET drvier fail


Aug 26, 2016
I use Lenovo G50-70 i3 model. I was happy with the laptop's performance until recently when i started playing an online game (FIFA Online) which needs a good connection. I have always used WiFi for my laptop but wireless is not as good with gaming, It gives me the lags. So, I decided to attach a wire to my laptop but the problem now is my ethernet port isn't working,
i went into my device manager and looked for my driver, there is a driver called Realtek PCIe GBE Family Controller that has a yellow exclamation along with it. I uninstalled the driver and pulled my driver CD out and tried to install the realtek LAN driver and the same driver failed to install again. The ethernet Controller installs but this PCI controller isn't working at all, I have tried the latest drivers from Realtek Lenovo HP and even intel and nothing works.
Please help I need to start gaming again.
p.s. its Win7x64
