Onboard LAN not working

Hey all

So I bought a brand new motherboard; the ASUS M4A78-HTPC. I installed the driver for the onboard LAN from the supplied disc but when I insert the Ethernet cable the network icon on the task bar lists "unidentified network" and "No internet access". I am unable to use the internet and have tried various LAN driver versions with no success. Any ideas?

Thanx


System Specs
Windows 7 OS
MSI K9A2VM-FD 780V Socket AM2+
Coolermaster 700W Power Supply
4 GB Geil RAM DDR2 800
XFX ATI 5770
Creative X FI Xtreme Gamer
CM STORM Case

Are you running it thru a router?

If so, you made need to copy the PC's MAC Address to the router.

Else, do a clean reinstall of Windows 7, and it should load the driver on setup. Mine did on my Asus P6T. Windows loaded all the drivers for anything onboard (i.e. Sound, LAN) without any interaction by me. It did it of one of the first boot ups/restarts.

Hi

Yes i am running it through a router. Does the MAC address reset itself when a new motherboard is involved?

Thank You

I did disable the MAC address filtering on the router yesterday through another PC but that didn't change anything...

First, when you open the Device Manager and expand the [+] Network Adapters tree does your NIC show-up? {Realtek PCI-E GbLAN controller 8111C}

Yes it does show up. Everything is normal only when i plug the ethernet cable i get two LED's one orange and one yellow but no access to the internet.

If that fails then either turn-off your router ~ 10 minutes or reset your Router.

This is Windows problem and not a MOBO issue.


I've tried doing a clean install of windows 7 with no success even though windows installs the driver automatically.
I've also tried turning my router off for 10 minutes. What is really weird is that the motherboard that I am currently using (MSI) the internet works perfectly....
The latest thing I have tried is flashing the BIOS to the latest version which also didnt solve anything.

When I said "Windows" I meant configuration & settings, not reinstall + BIOS flash both of which I severely doubt could be the issue. Then I asked about the Device Manager which confirms that the NIC is installed - I made a reference of the type and I assume it is as I posted. Leaving Windows configuration, Router or possibly the NIC CAT-5 or 6 cabling or connections. To R/O a bad cable try the cable on a different PC or use a different cable. If you inadvertently used a "Crossover" cable by mistake you'll also have troubles connecting on many routers.

In addition, Reseting the router {reset button} with R/O router.

^However I am totally confused with that comment and then the next - please clarify.

Is your LAN chip on motherboard 1 Gbps ? If yes, sometimes you may have a problem when you you use a patch cable of Cat 5-E between your motherboard and the modem/router. There happens to be a communication error. You should either run a patch cable of Cat 6 or reduce the speed of your LAN connection to 100 Mbps in the configuration settings of your LAN chip in Device Manager. Of course, I assume your patch cable is not defective.

By the way, MAC address filtering of your LAN should not be of interest when you hardwire your LAN to the modem/router. It may be important when you connect wirelessly. This is so, at least, for my Linksys router of WAG 300N.

The motherboard which i am currently using which is in an MSI is fine with the cable I am using and I do have access to the internet.

I am unsure of the chip on the motherboard but I do know the LAN is set to Auto Negotiation in the settings and I have tried various speeds on half and full duplex with no success.

I've had the same problem on an ASUS P8Z77-M motherboard connected to a powerline device. COuldn't work out what was wrong, tried a laptop on the same powerline unit and it worked straight away. So obviously the fault was with my newly built desktop.

after many drivers and restarts I simply un-installed Asus' iNetwork control in the Asus utilities in the start menu and after a restart and initial network identification I'm connected and achieving advertised speeds at peak times, oh the joy of breaking away from a wireless adaptor!!

I am curious as to whether there's a work around though as i liked the idea of the iNetwork feature..

Anyway, OP and all others over the world reading this, try this simple fix before faffing with new drivers or sending your board back to the retailer.

To clarify, I was and still am running Realtek PCIe GBE Family Controller on Windows 7 64bit
