Won't detect the ethernet cable.

I think that if the last router worked then the problem is with the new router and not the operating system. You should try using another router.

Sorry for being so late, but I've tried it with another one and it still did not work.

Do you remember how you solved this bug? I have the same problem

Okay let me tell you my problem and the reason for updating in this thread.

I have a Windows 8 system. I am having issues connecting to internet(LAN cable).This was working fine a few days back. If I change the hard disk and connect a different hard disk which has Windows 7 it works perfectly fine. Notice the only thing changed here is the hard disk with different OS in it. This confirms that issue is not with the lan/ethernet cable/port.

I am currently seeing this message - "Ethernet 2 doesn't have a valid IP configuration".
When I checked the IP that's assigned this is what it says:

Autoconfiguration Ipv4 Address 169.254.31.190
Ipv4 Subnet Mask 255:255:0:0

Then i tried going to command prompt and gave
ipconfig /release

This wasn't of much help as it failed with some error message

Then I tried running sfc/scannow and dism /Online /Cleanup-Image /RestoreHealth looking at some of the posts posted here and online.

Running dism I am getting the same error as reported in this thread.

I have couple of questions:
1) Are these right steps to follow to fix this for internet connection issue ?
2) What do i need to get this valid ip configuration issue resolved ?

Note: There is no issue with the cable because i fixed another hard disk and booted and the internet was connecting there.

I don't have much idea in all this.I followed some of the things which were posted on net and checked.
Any help will be greatly appreciated.
