Windows 7: Realtek PCIe GBE Family Controller keeps disconnecting - my fix.

Realtek PCIe GBE Family Controller keeps disconnecting - my fix.

So I had this issue where my ethernet connection on my Lenovo B570 laptop keeps disconnecting about every couple of minutes and the link lights would turn off then it would reconnect. So I did the following:

visit Realtek and install the latest driver. (Might not be necessary but do it anyways)
open Network and Sharing Center, click on Manage adapter settings, right click Realtek PCIe GBE Family Controller (Local Area Connection) and select properties. Click on configure, switch to advanced tab and change the following properties:

Auto Disable Gigabit > Relink Battery or AC
Green Ethernet > Disable
Energy Efficient Ethernet > Disable

My ethernet connection has been stable so far.

Hope this helps anyone.

Thank You Very Much! Your manual really helped me!
I was dancing with a tambourine for 3 nights, before i found Your message.
I Must add that 1 step was made by myself: link speed/duplex settings were changed from Auto to 10 Mb, Full Duplex. And only after that link lights began to work....

Quick update: I switched Auto disable gigabit to disable and it works fine so now I have gigabit speed.
