I've created ubuntu-14.04 image and restoring on disk and Motherboard model is GIGABYTE GA-H61M-WW with this Ethernet controller:
Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)
Now issue is that, as Ubuntu boots up, the link light will go off Ubuntu reports cable is disconnected and ethtool result:
Link Detection: no
For this, too many help over the internet and following many forums but not getting solution yet!
Main issue: After attached Ubuntu disk, then Switched back to windows 7 disk which was already worked Ethernet card but Now showing Ethernet unplugged !!!
So that reinstall drivers and boot with Linux Live OS but Ethernet not working..., I performed same on two same model PC's and facing same network card issues! So I don't want to performed on another PCs.
Everything are fine like cables, switchs and connectors...
My question is, in built Ethernet is physically failed by Ubuntu on both machine?
How can first solve this issue in windows 7 and after Ubuntu?
