Windows 7: Ethernet not detected

05 Jun 2010   #1

Ethernet not detected

Hello all!
I know there have been some threads about this issue before, but I couldnt find a solution to my problem there:
Until today I had Windows XP running on my new system, which consists of:
  • Mainboard: Asus M4A87TD
  • Athlon X2
  • Ram and other hardware.
The network adapter is a onboard solution and is:
RTL8111E PCIe Gigabit Lan controller featuring AI NET 2 (by Realtek).
From there it is connected via cable to a router which itself is connected to a dsl-modem.
Running under Windows Xp I could connect to the internet and to the network without a problem.
Now I installed Windows 7 Home 64bit. After installing all drivers I still get the error message: No networkcable connected.
What I did so far to get a solution:
- Download and install the newest driver for the network adapter (7.018) from the realtek site
- Download and update BIOS (Version 0810) from asus site

After that the networkadapter showed in DM that it was working and running - what it obviously didnt.

- Installed Windows7 32bit - same problem
- Installed Ubuntu in 32bit and 64bit version - same problems as under Win7
- Cable and router work fine, have 3 other PCs on the router, 2 with Xp/Linux and one with vista
- I also tried to boot the pc without cable connected and plug it in later - no changes

Then I put Windows XP back on it and the connection worked again -_-

The next step I will do is to update the router software (ofc I did restart it like 5 times until now), but I doubt that it will help much.

Any thoughts on that problem?
Thanks in advance!

Did you install the chipset drivers available from Asus?

I did install the chipset drivers. I just checked again and they are all the latest versions.

I solved it now somehow. Dont ask me how exactly but it is working now. My best guess is that the static IP I put into the advanced properties of the network adapter worked this time. It is not static anymore but maybe it triggered something who knows

At least it works now

Ethernet cord not detected
Hey guys, I just installed Windows 7 on a new computer, and I can't get it to detect my ethernet cord. The light on the card that the cord plugs into lights up, and I could access the internet when running a Knoppix live CD, so I don't think it's a hardware problem. I'm fairly inexperienced...
